Our Services

Coastal-Ready Roofing in Friday Harbor

Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs tailored for Friday Harbor’s salt-air and heavy rains. Our certified roofers begin with a thorough deck inspection, apply high-performance underlayment, and seal flashings with marine-grade sealants to prevent leaks and ice dams.

We perform a structural evaluation to uncover hidden rot or framing issues—offering courtesy rot repair at a nominal fee. Backed by manufacturer warranties and our commitment to on-time completion, your new roof will protect your home and enhance its curb appeal for decades.

Durable Siding Installations in Friday Harbor

Refresh your island home with low-maintenance vinyl, fiber cement, or engineered wood siding from Alpine Siding Pros. Our crews align trim with laser precision, install continuous waterproofing membranes, and caulk every joint to block moisture and drafts in Friday Harbor’s maritime environment.

Each project starts with substrate and sheathing inspection. By combining top-tier materials with our perfected water-barrier techniques, we deliver an energy-efficient, mold-resistant exterior that endures UV exposure and temperature swings—boosting both durability and sea-view aesthetics.

Energy-Efficient Windows for Friday Harbor Homes

Upgrade to ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows installed by Alpine Siding Pros. Our precise measurements and advanced sealing methods eliminate drafts, reduce condensation, and improve thermal performance in Friday Harbor’s ocean-influenced climate.

We assess existing frames and flashing before carefully removing old units, then complete a meticulous cleanup. Enjoy lower energy bills, superior soundproofing from ferry traffic, and unobstructed views of the Salish Sea and San Juan Islands.

Custom Decking Solutions in Friday Harbor

Extend your living space with a bespoke deck designed for Friday Harbor’s unique terrain. Alpine Siding Pros uses pressure-treated lumber, marine-grade composites, or hardwoods rated for coastal moisture. Our installers follow local code for joist spacing, ledger attachment, and proper drainage.

From simple viewing platforms overlooking Griffin Bay to multi-level entertainment areas, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that enhances your Friday Harbor home’s value and outdoor living experience.

Why Alpine Siding Pros Excels in Friday Harbor

Alpine Siding Pros blends 20 years of island-region expertise with a deep understanding of Friday Harbor’s marine climate and architectural character. Our Bellingham-based team partners with Washington suppliers to source premium roofing, siding, window, and decking materials—ensuring fast delivery and local support. We deliver transparent bids, manufacturer-backed warranties, and community-focused service, guaranteeing every project is completed on time, on budget, and built to last.

Mastering the Building Envelope

We treat your Friday Harbor home’s exterior as a unified system—coordinating roofing, siding, windows, and decking to form a seamless barrier against moisture and air infiltration. Our crews install high-performance vapor barriers, marine-grade flashings, and premium sealants at all critical junctions. By inspecting and reinforcing underlying sheathing and framing, we stop rot and mold before they start, maximizing energy efficiency and indoor comfort.

Transparent Pricing & Rot Repair

Integrity is our hallmark. At Alpine Siding Pros, rot repair is quoted separately as a courtesy service—charged only if we uncover damaged sheathing or framing. Every estimate line-items materials, labor, and any rot remediation, so Friday Harbor homeowners never face surprise fees. This transparency lets you budget confidently and keeps your project on schedule and on budget.

Local Partnerships & Island Community Focus

As a locally based Bellingham contractor serving Friday Harbor, we partner with Washington-state manufacturers and suppliers—supporting the regional economy and ensuring rapid material availability. Our crew lives in the communities we serve, understands island permit processes, and respects local aesthetics. From minor repairs to major recladding, we communicate clearly, adhere to timelines, and treat your property with care—building lasting relationships one home at a time.
