Metal Roof Maintenance

Steps to Maintaining Your Metal Roof:

  1. You should look at your roof at least twice a year, in the spring and in the fall.  Check all seams, around the sides and around all other objects on your roof (vents, plumbing stacks, antennas, etc).
    • If the roof coating is peeling, flaking or cracking, then it is time to re-do that area
    • If you find any punctures (from falling debris) your roof will require some repair
  2. Prepare your roof for coating the same way you’d prepare your walls for paint.
    • Prep the surface with a wire brush or scraper, removing as much of the old roof coating as possible, especially the stuff that’s flaking.  This sometimes takes a bit of elbow grease, but the final result is worth it!!
    • Then clean the surface with a product that does not leave behind a residue.  We like Tri Sodium Phosphate (TSP).
  3. Now you’re ready to seal your seams.
    • Some people like to use fiberglass tape with the seam seal (this does an excellent job, but is not essential).
    • We suggest a rubber based product, they will last longer and adjust better to temperature changes.  We use DYCO 20/20.  Spread your seam seal on with a disposable paint brush. Use 2 thin coats, allowing time to dry between applications.
    • If your roof is galvanized steel you may wish to coat the entire surface, to avoid deterioration and pinholes.
  4. Relax and Enjoy!!!
