Yes, a full roof replacement is the definitive solution for roof decking rot. Our process starts by safely removing all old shingles and compromised decking. We then install new, treated plywood decking to create a solid, moisture-resistant base before applying high-quality underlayment and shingles. This not only fixes the rot but also addresses underlying ventilation issues common in our area, preventing future problems and securing your home's structure.

Absolutely. A leaking skylight often requires flashing repair or replacement, which we expertly integrate into siding or remodeling work. When we replace your siding or undertake a remodeling project like a bathroom update or room addition, we inspect and reseal the skylight perimeter with proper, weather-resistant materials. This coordinated approach ensures a watertight seal and protects your interior from water damage, making your entire exterior renovation more effective and durable.

When building a new room addition, guest house (ADU), or any new structure, we prioritize preventative roofing from the start. We use rot-resistant materials for the roof decking and install high-quality, ice-and-water shield underlayment, especially around potential leak points like valleys or where the new roof ties into the existing one. Our construction methods are designed to withstand local weather, ensuring your new space is built to last and free from the common issues we see in older Milltown homes.
