Mark's Roofing & Sealcoating | Roofing Services in Attleboro, MA 02703

A leaky roof valley is a critical issue, especially with our heavy New England rains. We start with a thorough inspection to find the source—often worn flashing or compromised shingles. Our repair involves carefully removing the damaged material, installing new, water-tight flashing, and re-shingling the area with proper overlap. We ensure the valley is correctly channeled to shed water efficiently away from your roof, providing a long-term solution to prevent future attic water damage.

Repairing roof deck rot is a structural fix. We safely remove the affected shingles and underlayment to expose the damaged decking (plywood or OSB). All rotted wood is cut out and replaced with new, treated sheathing to restore a solid base. We then re-install proper underlayment and shingles. To prevent rot, we recommend ensuring your attic has adequate ventilation to reduce moisture buildup and scheduling annual inspections, particularly after severe storms, to catch minor issues before they become major problems.

Sealcoating is a protective maintenance service that's highly beneficial for Attleboro's variable climate. It applies a protective layer to asphalt shingles, shielding them from UV rays that cause brittleness, thermal cracking from freeze-thaw cycles, and wind-driven rain. This process restores granules and waterproofing, extending your roof's lifespan significantly. It's a cost-effective way to bolster your roof's defense against the specific wear-and-tear it faces here in Southeastern Massachusetts.
