My comp shingle roof is nearing the end of its life and has lost a few tiles. Is there a coating product that can be applied?
It's a pitched roof.
The shingles coming loose should be remedied immediately, before expensive water damage is done.
Have a trusted roofing professional -- or better yet, your insurance adjuster -- come take a look at the remainder of the roof.
- Loose shingles can occur without serious degradation of the asphalt and fiberglass.
- The cause is usually high winds or hail, but wind especially if the roof is not pitched enough (less than 4:12).
I have recently seen a waterproof membrane in a spray can that is sold on TV.
- I would not recommend using anything like this in your case, as the shingle method creates a protective path for water to flow down a roof.
- Even if the membrane is waterproof, the overlapping action of the shingles would potentially be compromised.
- Plus, who knows how long something like that can hold up to the sun's ultraviolet rays?
My recommendation: Don't take shortcuts when it comes to protecting your home from water.
