Larsen Roofing | Roofing Services in Davison, MI 48423

A roof valley leak is serious and requires professional attention to prevent interior damage. At Larsen Roofing, we start with a thorough inspection to find the source—often worn flashing, cracked shingles, or ice dam damage. Our repair involves removing damaged materials, installing new waterproof underlayment and flashing, and carefully re-shingling the valley to ensure a watertight seal that handles Michigan's heavy rain and snow.

Moss traps moisture against your shingles, causing them to decay. We never recommend power washing, as it strips protective granules. Our safe, effective process involves applying a moss-killing solution, allowing it to work, then gently removing the dead moss. To prevent regrowth, we can install zinc or copper strips along the ridge—a small metal runoff during rain creates an environment where moss can't grow, providing long-term protection.

Davison's climate—with its freeze-thaw cycles, heavy precipitation, and shaded, tree-lined properties—creates the perfect conditions for valley leaks and moss growth. Valleys channel a large volume of water, so any weakness leads to major leaks. Moss thrives in our damp, shaded areas. Ignoring these issues leads to rotten decking, damaged insulation, and mold. Our localized expertise focuses on solutions built for these specific, recurring challenges to protect your investment.
