Our Services

Hillside-Ready Roofing Solutions

Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs engineered for Happy Valley’s heavy rainfall and gusty winds. Our certified roofers begin with a full deck inspection, apply high-performance underlayment, and seal all flashings to prevent leaks, ice dams, and wind-driven rain.

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

Weather-Defying Siding Installations

Refresh your Happy Valley home with low-maintenance vinyl, fiber cement, or engineered wood siding. Our installers align trim with laser precision, install continuous waterproofing membranes, and caulk every seam to block moisture, drafts, and pests in the valley’s damp climate.

Each project begins 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 durability and curb appeal.

Energy-Efficient Window Replacements

Upgrade to ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows. Alpine Siding Pros takes meticulous measurements and uses advanced sealing methods to eliminate drafts, reduce condensation, and improve thermal performance in Happy Valley’s variable weather.

We assess existing frames and flashings, remove old units with care, and complete a thorough cleanup. Enjoy lower energy bills, superior soundproofing from valley winds, and unobstructed views of rolling hillside landscapes.

Custom Deck Construction

Extend your outdoor living with a bespoke deck from Alpine Siding Pros. We design and build decks using pressure-treated lumber, composite materials, or hardwoods rated for moisture resistance. Our installers follow local code for joist spacing, ledger attachment, and drainage.

From single-level platforms to multi-tier entertainment areas, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that enhances your Happy Valley home’s value and outdoor enjoyment year-round.

Why Alpine Siding Pros Excels in Happy Valley

Our Bellingham-based team partners with Washington suppliers to source premium roofing, siding, window, and decking materials—ensuring rapid delivery and community support. We deliver clear bids, manufacturer-backed warranties, and personalized service, guaranteeing every project is completed on time, on budget, and built to last.

Mastering the Building Envelope

We treat your home’s exterior as a unified system—integrating roofing, siding, windows, and decking into a seamless protective barrier. Our crews install high-performance vapor barriers, precision flashings, and premium sealants at all junctions. By inspecting and reinforcing sheathing and framing, we prevent leaks and rot before they start, maximizing energy efficiency and indoor comfort in Happy Valley’s climate.

Transparent Pricing & Rot Repair

Honesty is our hallmark. At Alpine Siding Pros, rot repair is quoted separately as a courtesy—charged only if needed.

This transparency allows you to budget confidently and ensures your exterior project stays on schedule and on budget.
