Technical Bulletin #99 : Priming Metal Roofing

ISSUE

In some cases, older metal roofs require repainting and, in some cases, the property owners wish to repaint new metal roofs. Additionally, with some metal roof types or certain flashings, there can be mill finish metals which need to be painted on a roof system.

CONCLUSION

For information on repainting instructions, see Technical Bulletin #52. However, when looking for a primer paint to use in any of the above situations, consult with a quality paint store as to their recommendation. One product we have seen some success with is the Sherwin Williams Pro-Cryl primer. For roof systems which, from the initial installation, are expected to be quickly repainted, some manufacturers offer their products in a “primer only” state without the final topcoat applied or sometimes with a material called “paintgrip” applied to them.
