The roof is the most consequential envelope system on any estate — it defines architectural character, protects everything beneath it, and determines long-term maintenance costs. We install premium natural slate, standing seam metal, and clay and concrete tile roofing systems with the precision and detailing that luxury Marin County properties demand.
Every roofing project begins with a comprehensive structural assessment of the existing framing, sheathing, and drainage systems. We engineer correct ventilation, ice and water shield placement, and drainage solutions before specifying materials — because the most beautiful roofing material fails prematurely when the underlying system is not engineered correctly.
ConstruBay (CSLB #1106798) is based in Mill Valley and has executed luxury roofing projects across Marin, Sonoma, and Napa Counties.
What Is Included
The Marin Advantage
Roofing in Marin County's Wildland-Urban Interface zones requires Class A fire-rated materials that also meet the architectural standards of Marin's historic and design-review-sensitive neighborhoods. Our PlanPass.ai platform manages roofing permit applications that frequently involve simultaneous review by building and fire departments. We are current on Marin County Fire's ember-resistant vent requirements, Class A assembly specifications, and the specific roofing material approvals required in designated fire hazard severity zones — including communities in Mill Valley, Kentfield, Ross, and unincorporated Marin hills.
