Roof Overlay

What This Service Involves

A roof overlay installs new shingles directly over your existing single layer, avoiding the labor and disposal of a full tear-off. It only works when the current roof is structurally sound and dry underneath, which we verify carefully given how well our Northwest climate hides moisture damage. When conditions are right, an overlay is a faster, more affordable way to renew the surface before the next wet season. We inspect thoroughly first because layering over hidden rot would only trap moisture and shorten the new roof's life.

What Affects the Cost

Best Time of Year
