A roof is only as good as its installation. Dons Roofing Repair builds roofing systems designed for maximum longevity — with proper ventilation, premium materials, and meticulous workmanship on every project in Cotati, CA.
A new roof installation is more than laying shingles on a deck. A properly installed roof is a system — one that integrates weatherproofing, ventilation, drainage, and structure into a unified assembly designed to perform for 30, 40, or even 50+ years with proper maintenance. When any element of that system is compromised by poor installation, the entire roof underperforms — often without immediate visible evidence.
Dons Roofing Repair has installed roofing systems on hundreds of new construction and full replacement projects throughout Cotati, CA. Our installation crews follow manufacturer installation specifications to the letter — because violating those specs voids warranties that protect your investment.
Two roofs with identical materials can have vastly different lifespans based on installation quality alone. Improper nail placement causes shingles to blow off in the first major storm. Skipped ice and water shield causes ice dam leaks in winter. Misaligned flashing allows water infiltration at every transition point. These aren't hypothetical failures — they're the most common sources of the repair calls we receive on roofs installed by less careful contractors. Our installations are done once, done right.
For new construction in Cotati, CA, we work directly with builders, contractors, and architects to ensure the roofing assembly integrates correctly with the structure. We handle permit applications, material procurement, scheduling coordination, and final inspection documentation — making us a reliable trade partner for any residential build.
