Our Services

Lakeside Roofing Solutions in Lake Whatcom

Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs engineered for Lake Whatcom’s humidity, heavy rains, and seasonal winds. Our certified crews conduct a thorough deck inspection, apply industrial-grade underlayment, and seal flashings with marine-rated sealants to prevent leaks and ice dams.

Before installation, we perform a structural assessment—uncovering hidden rot or sheathing damage—and provide courtesy rot repair at a nominal fee. Backed by manufacturer warranties and our punctual completion guarantee, your new roof will protect your home and enhance its waterfront charm.

Durable Siding for Lake Whatcom Properties

Upgrade your Lake Whatcom home with low-maintenance vinyl, fiber cement, or engineered wood siding. Our installers align trim to millimeter accuracy, install continuous waterproofing membranes, and expertly caulk all seams to block moisture, drafts, and pests in the lake’s microclimate.

Each siding project begins with substrate and sheathing inspection. By combining premium materials with advanced moisture-barrier techniques, we deliver an energy-efficient, mold-resistant exterior that endures UV exposure and temperature swings—boosting both longevity and curb appeal.

Energy-Efficient Window Upgrades

Alpine Siding Pros installs ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows designed for Lake Whatcom’s variable weather. We take exacting measurements and employ high-performance sealing to eliminate drafts, reduce condensation, and optimize thermal comfort.

We evaluate existing frames and flashing before carefully removing old units, then complete a meticulous cleanup. Enjoy lower energy bills, superior soundproofing from lakeside activity, and clear views of the water and surrounding forest.

Custom Deck Construction by the Lake

Transform your outdoor living with a bespoke deck from Alpine Siding Pros. We design and build decks using pressure-treated lumber, composite boards, or marine-grade hardwoods rated for moisture and sun exposure. Our crews adhere to local code for joist spacing, ledger attachment, and drainage.

From simple lakeside platforms to multi-level entertainment areas, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that maximizes your Lake Whatcom home’s outdoor lifestyle.

Why Alpine Siding Pros Excels in Lake Whatcom

Alpine Siding Pros brings 20 years of Pacific Northwest expertise and an intimate knowledge of Lake Whatcom’s lakeside environment and building styles. Our Bellingham-based team partners with Washington suppliers to source premium roofing, siding, window, and decking materials—ensuring swift delivery and local support. We offer transparent bids, manufacturer warranties, and community-focused service, guaranteeing every project is completed on time, on budget, and built to last.

Holistic Building Envelope Integration

We view your home’s exterior as one cohesive system—coordinating roofing, siding, windows, and decking to block water and air infiltration. Our crews install high-performance vapor barriers, precision flashings, and premium sealants at all critical junctions. By inspecting and reinforcing underlying sheathing and framing, we prevent leaks and rot before they start, maximizing energy efficiency and indoor comfort.

Transparent Pricing & Courtesy Rot Repair

Integrity is our cornerstone. Rot repair is quoted separately as a courtesy—charged only if needed. Every estimate line-items materials, labor, and any remediation so Lake Whatcom homeowners never face surprise fees. This transparency allows you to budget confidently and ensures your exterior project stays on schedule and on budget.

Local Partnerships & Community Commitment

As a locally owned Bellingham contractor serving Lake Whatcom, we partner with Washington-based manufacturers and suppliers—supporting regional businesses and ensuring prompt material availability. Our crew lives in the communities we serve, understands local codes and permit processes, and respects neighborhood character. 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.
