 Alpine Siding Pros installs asphalt shingle and metal roofs tailored for downtown’s combined urban and marine exposures. Our certified installers perform thorough deck inspections, apply high-performance underlayment, and expertly seal all flashings to prevent leaks, ice dams, and wind-driven rain.

Mastering the Building Envelope

We treat your home’s exterior as one cohesive system—roofing, siding, windows, and decking working in harmony to fend off moisture and air infiltration. Our crews install high-quality vapor barriers, durable flashings, and premium sealants at all critical junctions. By inspecting and repairing underlying sheathing and framing, we prevent rot and mold before they start and maximize energy efficiency and indoor comfort.

Transparent Pricing and Rot Repair

Hidden fees erode trust. At Alpine Siding Pros, we separate rot repair from core services—charging only a small courtesy fee when structural replacement is needed.
