The inspection

What we found. A failing closed, California-style valley with worn and damaged shingles along it.

What we recommended. Remove the valleys and fully replace them on both sides, install Malarkey Omniseal three-ply membrane in the dead valley about four feet up, and rebuild with new cropped valleys and colour-matched IKO Cambridge shingles.

A valley repair can save a roof

When the rest of the roof is sound, rebuilding a failing valley properly can stop leaks for years without a full replacement.
