How Much Does a Metal Roof Cost, and Why? Take The Guesswork Out Of The Process By Involving a Professional.

Wednesday, April 16th, 2014

Among many of the frequently asked questions we receive, the first and most prominent of them all is, of course, “How much does a metal roof cost?” This is the number one question our consultants receive from homeowners all over New England. This is also the number one question we usually cannot answer over the phone. To answer quite bluntly, giving an estimate over the phone for an aluminum metal roofing system is a metal roofing contractor’s nightmare – there are simply too many complex factors involved. Save yourself the trouble and speak with a reputable metal roofing contractor to set up an appointment for a free estimate – you will save yourself the trouble of trying to figure out the price on your own, become aware of the potential scope of your project, and become much more educated on the variety of different metal roofing products.

One Shortcut to Establish a “Ballpark” Range

First, keep in mind that a full contract for aluminum metal roofing will be about 2 ½ to 3 times the cost or more of an asphalt roofing contract. One way to find out if metal roofing cost is in your potential scope *without* meeting with an aluminum metal roofing contractor, is simply to contact a few local, competent asphalt roofing contractors for their quotes, and then just multiply by 2 ½ to 3. Understand that prices for asphalt roofing can vary greatly depending on the company – be sure you meet with a few licensed and insured contractors so you know that you are getting accurate pricing based on your local area’s roofing industry standards. Surprised that the Metal Roofing Blog is suggesting you to meet with an asphalt roofing contractor? You should be – as discussed earlier, an aluminum metal roofing installation is 2 ½ to 3 times the cost (or more, depending on the product) of asphalt roofing. Do the math – figure out if aluminum metal roofing is in your ballpark, then move forward by meeting with a metal roofing contractor to see what product will be the best fit for your criteria and your home. This is the simplest way to get a ballpark price for aluminum metal roofing without actually meeting with a metal roofing contractor, and it has the added advantage of allowing you to consider whether an asphalt roof might actually be an ideal alternative for you.  Finally, save yourself the trouble and meet with a reliable, reputable metal roofing contractor, who can guide you through the decision process and greatly reduce the effort required to research your options.

If you are still reading at this point, we are guessing you still do not want to meet with a metal roofing contractor. You think you want to find out on your own how much to expect to spend on metal roofing costs for your home … but remember, many contractors are more than willing to do this for you for free. Good luck. Oh well – what do we know?

Calculating a Metal Roof Cost Estimate Range for an Aluminum Metal Roofing System

Begin by picking up the following tools to aid you in this complicated process: paper, a tape measure, a calculator, and a pen or pencil. The first step is to figure out the total square footage of your roofing. To do so, use the tape measure to find the length of your roof surface from one side to the other. Find the width of your roof from the eave to the ridge, and multiply the length and width to find the area. If the roof is awkwardly shaped (anything other than a rectangle), find the area of smaller sections at a time and add them together. Repeat all of this until you have measured all of the roofing surfaces. Add them together. You now have the square footage of your roof.

Unfortunately, the square footage is not the only factor that determines the price point for a metal roofing system. Be mindful of all of the complexities of your roof, because, well, they are complex. The complexity of the roofing is a major factor affecting the price point. These complexities include (but are not limited to) multiple angles and pitch, valleys, and hips.

Penetrations through the roof are just as important, such as: pipes, vents, skylights, and chimneys. Understand that these penetrations require detailed flashing, and usually, the difficulty of the flashing is highly subjective due to the many different styles of homes.

Understanding what metal roofing product meets your criteria and your home affects the price due to many factors, but more importantly, the price point can be greatly affected depending on the condition of the asphalt and the amount of layers. Excluding standing seam aluminum metal roofing, a traditional metal shingle roofing system can be installed over one layer of asphalt – provided that the single layer of asphalt and the decking is in sound condition. So, what about standing seam? Standing seam lays flat on the surface and will cause irregularities in the panel over a layer of asphalt, so all of the previous material must be stripped.

You are probably asking yourself, “I just got the square footage. I have a couple skylights, now what?”

We are going to conclude with a sample estimate based on the standard 2014 New England metal roofing industry prices. This is going to be a ballpark range and is not, by any means, a concise estimate. Take it with grain of salt, and it should only be used as a reference point. That said, we will provide a simple sample metal roofing cost of an aluminum metal roofing system – broken down piece by piece. Compare your findings to the following figure to find out your ballpark price range for an aluminum metal roofing system.

The Simple Sample Aluminum Metal Roofing Ballpark Price Range

*(PLEASE note that these figures are as of April, 2014, for the New England metal roofing industry)

Consider the following – try to relate it to your home and your measurements …

Our sample is going to be a house with a full shed dormer off the back.
1.) Flashing the cheeks of the dormer will generally cost between $700 – $900.

2.) This house will require head wall and sidewall flashing, the cost being $500 – $700 to re-flash around metal roofing.

3.) This house has a footprint of 60’ x 40’ and has valleys and vinyl siding. Figure that the roofing surface sums up to 2075 sq. ft., which equates to 21 squares. For aluminum metal roofing, the average New England metal roofing industry cost would be about $1100 – $1400 per square (10’ x 10’ area), which makes the bulk of the metal roofing cost between $23000 – $29000.

4.) Remember that complexities will greatly influence the price. This sample roof has 2 bathroom vent pipes, which usually cost $100 – $200 per pipe. Figure this house has 2 skylights on the front of the roofing, measuring approximately as 16’ x 40’. In this case, it would cost between $200 – $300 for the flashing around each skylight. If, like in many cases, this house needs replacement skylights, you are looking at around $800 – $1200 per skylight – plus the cost of the skylight. This is to remove, replace, and re-flash.

5.) Continuing with this simple sample home, let us say this house has a center chimney measured to roughly 3’ x 3’. Chimneys in New England are usually flashed with copper and lead, so understand that they must be flashed with the same type of material as the roofing or it could be subject to electrolysis. Electrolysis takes place when one metal eats up the other, so if you are considering an aluminum metal roofing system, your chimney will probably need new flashing. The New England metal roofing industry cost for chimney flashing is usually between $500 – $1000+ depending on the size of the chimney and the condition it is currently in. Occasionally, the chimney will need to be re-pointed because dealing with a chimney in poor condition after a metal roofing system is already installed could create future problems.

6.) Rule of thumb: the lower the pitch of the roof, the lower the metal roof cost; the greater the pitch, the greater the metal roof cost. We will say that this roof has 1 layer of asphalt in good condition – as in, the shingles are lying flat and not crumbling. In this case, we will say the roof is about 15 years old. The roof deck, which is the wood under the shingles, is in considerably good shape. Because of this, this is a job that could have an aluminum shingle layover without stripping the asphalt. The chimney would have to be re-flashed because it is a different metal. Both skylights are in good condition so they also just need to be re-flashed. There is no ridge vent or gable edge vent on this house, so the venting needs to be corrected. Answering a common question among homeowners, “Can you vent a metal roof?” – The answer is yes. This is done by adding soffit vents and cutting in a ridge vent. The price range for this would be between $500 – $1000 depending on what needs to be done.

Break down:

  • Cheeks of the dormer flashing – $700 – $900
  • Head wall and side wall flashing – $500 – $700
  • 2075 sq. ft. = 21 squares – $23,000 – $29,000
  • (2) bathroom vent pipes – $100 – $200
  • Flashing around (2) skylights – $800 – $1200
  • Flashing around the chimney – $500 – $1000
  • Soffit Vents – $500 – $1000

Total estimated ballpark range price without ever visiting the property = $26,100 – $34,000

Note: Specialty Materials Can Lead To Significantly Higher Costs

An in-depth review of other metal roofing types besides aluminum is beyond the scope of this article. A copper or zinc roof both have additional advantages, however, they significantly add to the cost burden of a metal roof. That said, copper roofs and zinc roofs can be a wonderful enhancement to a home’s visual appearance and value.

Conclusion

Do not fall for the gimmicks that many metal roofing contractors use to get you to their websites. No website will ever tell you exactly how much a metal roofing system will cost for your home. Why? Because it is impossible, as you can see by the widely ranged ballpark estimate we have presented here. Gimmicky advertisements, such as metal roofing calculators, discounts, and the like – are almost always SCAMS. Lastly, we do not want you giving yourself a headache when trying to estimate the cost for a metal roof for your home. As outlined earlier, this is as ballpark range as it gets and there is so much involved when calculating the price for a metal roofing system, that the best approach is simply to have a professional come out and actually observe your situation with his own eyes. We mean it when we say it: save yourself the trouble and meet with a professional metal roofing contractor.

Spring Cleaning: “I’m In New England, When Is The Best Time To Get Metal Roofing?”

Friday, March 21st, 2014
New England Spring

http://www.discovernewengland.org/seasons/spring/

The Northern Hemisphere is beginning to tilt towards the sun as we are approaching warmer weather. The snow is melting, and homeowners all over New England are simultaneously beginning to do work on their homes. A common question among homeowners is when the best time is to replace their roof with metal roofing. Though it is much easier for most homeowners to do their home improvement when the weather is warmer, most experienced metal roofing companies will have the endurance and expertise to work in most cool or warm conditions. Believe it or not, residential metal roofing is actually a four-season industry. Most contractors in this industry will have their crews working all 12 months out of the year, installing aluminum, zinc, or copper roofs year-round.

The spring and summer seasons are when this industry is approaching it’s “busy season”. Because of this, the backlogs of projects under most metal roofing contractors are going to be much longer than they are during the cooler seasons. Homeowners will have to wait quite a bit longer to get their new roof put on than they generally would during the cooler, slower seasons.

“So, when is the best time to install metal roofing?”

A quick answer to that question is, truly, “Whenever you can.”

There are, however, positive and negative aspects for each season regarding when a metal roof should be typically installed on a home. Summer may seem to be an appropriate time to have a roof installed, but believe it or not, it can be considered among the worst. Why? The sun is out, it is warm, the conditions are fair – there is no better time to put a new roof on the house! This is absolutely wrong. Can you imagine being on a roof for 10 hours at a time in near 100 degree weather?

Just how it can be too cold for metal roofers to work in the winter, it can also be too hot. The relaxing summer days are when the family is leisurely lounging around their house and yard; especially when the children are playing in the yard with their beloved pets. Though most reliable contractors will have their crews do a simultaneous job clean-up while installing the roof, there is a much higher risk of landscaping around your home to potentially suffer minor damages. Before the warmer part of the spring season – before you begin doing your yearly yard clean up – is the ideal time frame for metal roofing to be put on the home. That way you will not be seeing any potential mess from the installation crew after you have cleaned up your yard. This reason is why later fall is an excellent time for installation as well.

The other side of the spectrum, the winter, is also not the best time for an installation. However, keep in mind that you will be beating the “spring and summer rush” that most New England metal roofing contractors face if you decide to get your new roof during this season. Installing a metal roof in the winter can be a struggle and usually takes a lot of patience. There are a lot of variables that can slow down an installation during the winter, such as conditions being too cold for the installation crew, heavy ice, wind, and snow. These variables can be restrictive to the installation process; so in some cases, homeowners may have to wait a bit longer than they initially expected. That being said, planning a new roof for a winter installation will put the homeowner before the warmer season rush, so your roof will be all set for the warmer season and will not prevent or restrict any other additional home improvement endeavors.

“When should I get metal roofing, then?”

As outlined earlier, as soon as you can. Because installing metal roofing is a long term investment for you and your home; the sooner, the better. You must also keep in mind that if additions are being planned for the home that will tie into the roof line, save yourself the trouble and get the addition at the same time as your new metal roof.

Keep in mind that winter is generally considered to have the harshest weather conditions out of all of the seasons in New England, and one of the primary reasons to get a metal roof is to protect your home. Throughout the New England winters, ice damming can be a problem on most homes with conventional asphalt roofs. Homeowners say to themselves that they can wait because they are going to replace their roof anyway. This is a common fallacy. Ice damming not only does damage to the roof, it can actually do damage to the home as well. The reason is that when there is poor ventilation in the attic, the warm air will melt the snow on the roof; that in which can leak under the shingles and into the house. This can cause internal damage, mold growth, rotting, and unhealthy air that you are potentially inhaling every day and night. Read more on how dangerous ice dams can potentially be…

In conclusion, there is no better time to get a metal roof than now. Regardless of when this is being read, the answer is still now. There are advantages and disadvantages to doing an installation during each season, and these factors are always going to be subjective to each homeowner. Do what applies best to you and your home. Initiate the process and speak with a metal roofing contractor today to get your free estimate and ventilation analysis.

Mother Nature: Protect Yourself, Your Home, and The Environment With A Metal Roofing System

Friday, March 14th, 2014

Advanced metal roofing technology that has sprung up over the last few decades includes reflective paints to increase energy efficiency, solar shingles that actually captures the sun’s energy and convert it into electrical energy, and metal roof components that interlock. Metal roofing on a home, in a way, can resemble a knight in armor … metal roofing provides armor both to the home as well as its occupants.

Storms have historically and continually caught many off-guard. On the summer morning of August 29, 2005, the Gulf Coast was struck with a category 3 hurricane. Winds blew between 100 and 140 mph, stretching up to 400 miles across. The impact from these winds infiltrated levees and caused severe flooding in many areas in Louisiana, Mississippi, and Alabama. This storm became known as “Hurricane Katrina.”

A Metal Roof is Like a Personal Suit of Armor

Whether or not your home is off the Gulf Coast, in Florida, Cape Cod, or any coastal area in New England, it is important to have a roof that can protect your home. You may not live in an area prone to hurricanes, but who knows if it eventually will be? Your home needs a personal suit of armor. Metal roofing is hurricane rated up to 120 mph. One of the reasons this system is so resistant to wind is because the panels interlock. Metal roofing is very light weight, and with the roofs ability to interlock to itself on all four sides, this system will withstand numerous environmental situations, such as: hurricane winds, heavy snow, and rain.

Hurricane Katrina

Hurricane Katrina

Interlocking Roofing Panels

Though New England has not been hit with many hurricanes lately, who can predict when one will eventually have a significant impact in this area? Consider that anywhere with reasonably high winds or the possibility of any potential hurricane is present, you can benefit from a metal roof to protect your home from that potential impact. Know that if the roof suffers from a hurricane, your home will suffer too. This is not to be played off as something minor – in the worst case, a hurricane could completely destroy your home. It is smart to learn from your own mistakes, but it is even wiser to learn from others. You do not need to learn after your home is already destroyed. Look at the damages faced by the hurricanes in Louisiana and Florida, for example. Most of the roofs that remained throughout those storms were the ones with aluminum metal roofing with panels that interlock – these homes were protected by their own personal suit of armor.

Environmental Friendliness

Metal roofing is the most environmentally friendly roofing option for most homes. Choosing aluminum over asphalt makes you a part of the solution, not the problem. Did you know that over 95% of the base metal for aluminum metal roofing is actually from recycled aluminum? Roughly 20 billion pounds of asphalt is dumped into US landfills every year. Unlike asphalt, this material is very advanced metal roofing technology. Metal roofing material does not use oil as its base resource. One may ask that if asphalt shingles need to be stripped anyway for the installation of metal roofing, aren’t we still contributing to the landfills? Wrong. As a matter of fact, in many situations, metal roofing can be installed over existing asphalt shingles without stripping them.

Reflective Capability

A metal roof will keep your house cooler in the summer and warmer in the winter. The reason is that metal roofing has radiant heat reflection, meaning the heat from the sun will reflect off of the roof, keeping the home cooler. Because of this, the excessive use of air conditioning during hot summer days will be drastically reduced. How does this affect the environment? The production of electricity used for air conditioning causes smog and pollution.

With a metal roof, you will not be producing as much electricity. However, the dead airspace between the metal roofing and roof deck provides great insulation. The metal gets hot, but the heat will not transfer into the house. In addition, your house will be able to retain heat much better during the winter. Most commonly, metal roofing with shinier metallic surfaces or milder colors are better at reflecting the radiant heat. Though, keep in mind that aluminum metal roofing will have natural emissivity, regardless. Special reflective paints, originally developed for military applications, have made great strides in increasing the reflectivity of metal roofs and is probably the most advanced metal roof technology to impact the market in recent years.

Besides the very environmentally friendly benefits of this roofing, metal roofing generally interfaces very nicely with solar panels. All of these benefits from a metal roof can actually fit into “cool roof” criteria, which means that in certain states, homeowners may be eligible for tax benefits. This said, here are a few frequently asked questions and misconceptions about metal roofing:

Isn’t metal roofing a new industry?

False. Although metal roofing seems to be gaining a lot of recent popularity, it has been widely used since the early 1800s. Even so, with many modern architects implementing metal roofing, homeowners figure their traditional home will not match with a metal roof. This, as well, is untrue. These products have become very advanced. Metal roofing comes in a variety of different styles and colors, such as the common “shake” style that mimics a wood shingle. Find out which metal roofing product suits your criteria.

Can’t Most Contractors Install a Metal Roof?

Absolutely not. In fact, you should steer clear from any roofing contractor that claims to install metal roofs but does not specialize in the field. Installing metal roofs is not an easy task. The craftsmanship is very specialized and advanced. Metal roofing requires many installation and bending techniques that only a specialized and experienced metal roofer exhibits. A common problem in this field is that many people receive an array of quotes for a metal roof, from a multitude of contractors and conclude by choosing the lowest price bidder. This usually leads to continual difficulties and problems due to a faulty installation which can ruin the promise of a “lifetime roof” with a plethora of repairs – often eventually adding up to the price that the reputable metal roofing contractor originally quoted, or more. In some cases, contractors have unknowingly installed agricultural metal roofing on homes, which later have had to be re-roofed with an architectural product. Save yourself the trouble; work with a reputable metal roofing contractor.

Metal roofing is too expensive!

It can be expensive, yes. But, like many investments, it will pay off. Along with the many environmental benefits and reducing your electric bills, a metal roof will increase the value of the home, and actually make the homeowner eligible for many tax benefits. Along with “cool roof” criteria in certain states, the wind and fire resistance of metal roofing, insurance companies will give discounts.

I live in a high wind area. Isn’t this a dangerous place for a metal roof?

As outlined earlier, the opposite is the case. There are many building codes that a roof must abide by in certain areas; hurricane regions in particular. Also, because the systems will generally interlock, metal roofing will be able to withstand high winds and prevent water from leaking in to the home. Remember, this roof is that of a suit of armor.

Metal roofing actually lasts long?

You will never have to re-roof again; because this industry has drastically advanced, metal roofing systems are expected to last up to 100 years. Because of the long term investment, the environmental benefits, and the incredibly specialized manufacturing and installation process, your roof will last you a lifetime.

Conclusion

Do yourself and Mother Nature a favor and get a metal roof. You will both protect the environment and protect yourself from the environment with this efficient shield of armor. Metal roofing has a come a long way, and you can make your home go a long way as well.

Metal Roofing Contractors: How to Select One

Wednesday, March 12th, 2014

Evaluating metal roofing contractors and selecting one should involve extensive comparative research between the top contractors in the industry in your location. The many factors involved in comparing metal roofing contractors include, but are not limited to: cost, experience, reputation, and flexibility.

Red Flags to Avoid

Because a metal roof is such a large investment for you and your home, simply signing a contract with the first contractor you meet with is the worst possible route. Beware of sales representatives who urge you to sign one during the meeting. Being pressured to sign a contract during your first meeting is not a reasonable way to be treated. These representatives care about you signing a contract, not you. If you fall into this trap, keep in mind that you will generally have three days to cancel it. After meeting with a few contractors, do not base your decision on the lowest price – that is often a major mistake. Many homeowners have found that paying just a small amount more is definitely worth the investment for a metal roof.

Metal roofing contractors with the most qualifications, highest level of experience, and largest number of glowing references are much more likely to give you a much better product worth your money. You will ultimately not spend much more long-term, and will very likely save money – by preventing any problems that come with choosing a less experienced or reputable contractor. As in most walks of life, “You get what you pay for.”

Flexibility

Other factors such as the shape and pitch of your roof, will have a significant impact on the price for a metal roof, as well as the style you decide to go with. A standing seam roof could quite possibly be a bit more than the various profiles of metal shingles; but keep in mind, there will usually not be much of a discrepancy in price from the metal shingles. That said, the contractor who is willing to do the work should have many options that meet your criteria.

Experience

Doing business with a contractor who specializes in metal roofing in particular is vital. Do the background research. Be sure any metal roofing contractors you consider have all of the licensing and proper certifications for the type of material they are installing. Verify the legitimacy of the business; don’t be afraid to ask for their tax identification, verification of their worker’s compensation, and liability coverage. Confirm that their insurance covers the entirety of the workers on your property. The importance in such situation is that, in case any of the workers get injured on your property, you want to be sure that you are protected from any potential lawsuits. Be sure to understand the logistics, the number of workers, and the time frame and length of time that workers will be on the property.

Lastly, be sure the company has a viable warranty so there is an understanding of any actions you as the homeowner could perform that could potentially void the warranty.

Reputation

How reliable is this contractor? Be sure to understand their reputation. Check out their listings on: BBB (Better Business Bureau), Angie’s List, GuildQuality, and Yelp – these are all fairly common websites for metal roofing contractors. Be wary if the contractor has no presence on any of these platforms. Read through these reviews and ensure that this company is legitimate and truly specializes in this field. Double check on their office locations, coverage, and phone numbers. Verify that the company has a list of referrals, references, and drive-bys. An experienced metal roofing contractor in this industry should have a list of at least two dozen references that you can personally call for a referral. Utilize the “drive-by list” provided by the contractor and check out previous installations they have done of the products you are most interested in.

Conclusion

Putting a metal roof on a home can be a great way to prevent problems, increase energy efficiency, and increase the resale value of the home. Always be sure to select a metal roofing contractor with a great reputation that has demonstrated that they do a solid job, and who is willing to stand behind their work.

Hartford Civic Center Not The Only Roof Damaged by Snow in 1978

Friday, March 7th, 2014
Hartford Civic Center Roof Collapse, 1978

Hartford Civic Center Roof Collapse Scene, 1978

Snow Roof Damage a Common Occurrence, But Often Preventable

The winter season in New England is notorious for its dreadful snow storms. Looking back, on January 18, 1978, when a prominent 10-day long storm hit Hartford, Connecticut, the Civic Center roof tumbled down to pieces due to the excessive weight of accumulated ice and snow. This disastrous collapse happened only about six hours after U Conn and U Mass had competed against each other within the arena. It is truly a miracle that this happened overnight when no one was inside the center. During this 10-day storm, the roof of the Hartford Civic Center was not the only roof damaged in New England. Buildings in the surrounding areas also experienced damage, to varying degrees, as buildings do every winter – from the accumulated effects of heavy snow loads, ice dams as a result of melting and refreezing, and so on.

People have the notion that snow and ice damage on their roof and home is inevitable. This misconception is widespread. Snow roof damage is actually completely preventable. However, it is such a common occurrence that homeowners do not take the correct measures to protect themselves, their family, and their home. Ever see icicles dangling around the edge of your roof? As pleasant to the eyes as they may be, this is a major warning that you may in fact have an ice dam on the roof, preventing the roof to properly drain water.

Ice dams are not an issue to be taken lightly. Why do they happen? If there is poor ventilation, the warmer air in the attic will melt the snow on the roof. This is bad because melting snow will cause the liquid to get underneath the roofing shingles and under lower areas before it becomes frozen again by the cold weather. This water has the potential to get underneath the roofing shingles and leak into the house, which would damage the ceilings, walls, etc. Not only is all of this water leaking into the house, it also brings the possibility of mold growth, rotting and damaging the roof deck and making the air inside the home unhealthy.

How is this prevented? There are immediate short term and long term adjustments that can be made to the roof to prevent this issue. The most immediate and dangerous step is to carefully step up on the roof and use a roof rake, which can be purchased at most home improvement retailers, to push the built up snow off the roof immediately after the storm. The amount of built up snow that a roof can handle is going to differ based on the type of roof and condition; however, the general rule is that there should be no more of a foot of heavy snow on the roof before it is removed. Once the snow is removed, find the location of any ice dams. Once located, chip at the ice carefully and try not to do any damage to the roof. Let it create a stream in a direction where it will flow off the roof easily. Finish by clearing any ice out of the gutter. Spread calcium chloride to aid the ice in melting; however, do not ever use rock salt, as this will damage the roof. Though this is completely doable for most people, getting up on the roof after a storm is very dangerous. Consider hiring an experienced roofing contractor to do this for you.

The most efficient long term method of prevention would be replacing your problematic roof with a metal roof. Besides all of the other great benefits of metal roofing, the metal roof has a smooth surface and a radiant reflecting property that gives it many heat handling characteristics to battle ice damming. A lot of metal roofs have an interlocking system, which also makes it much more difficult for water to get in. When replacing the roof, be sure an ice and water shield-type membrane is being installed. This shield will not protect the roof, but it will protect the house from water leaking in. Proper ventilation and insulation is also vital. The attic should be the same temperature as outside so the warmer air in the attic will not be melting the snow on the roof, as explained earlier. Speak with a metal roofing contractor today and determine which metal roofing product meets your criteria.
