Ridge-Tough Roofing in King Mountain

Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs engineered to resist King Mountain’s heavy rain, snow loads, and wind gusts. Our certified crews inspect the roof deck, apply industrial-grade underlayment, and seal all flashings to prevent leaks and ice dams.

Every project begins with a structural assessment to uncover hidden rot or framing issues—courtesy rot repair is available at a nominal fee. Backed by manufacturer warranties and our on-time guarantee, your new roof will protect your home and enhance its scenic ridge-top curb appeal.

Weather-Defying Siding Installations

Shield your King Mountain home with low-maintenance vinyl, fiber cement, or engineered wood siding. Our installers achieve millimeter-perfect trim alignment, install continuous waterproofing membranes, and caulk every seam to block moisture and drafts in the high-elevation environment.

Each siding job starts with substrate and sheathing inspections. By pairing premium 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 panoramic views.

High-Performance Window Upgrades

Upgrade to ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows designed for King Mountain’s variable climate. Alpine Siding Pros uses precise measurements and advanced sealing to eliminate drafts, curb condensation, and optimize thermal performance at elevation.

We assess existing frames and flashing before carefully removing old units, then perform a meticulous cleanup. Enjoy lower energy bills, superior soundproofing from ridge-top winds, and unobstructed views of the Cascades and valley below.

Custom Deck Construction on the Ridge

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

From simple viewing platforms to multi-level entertainment decks, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that maximizes your King Mountain home’s ridge-top vistas and outdoor enjoyment.

Why Alpine Siding Pros Stands Out in King Mountain

Alpine Siding Pros brings 20 years of specialized Pacific Northwest experience to King Mountain, WA. Our Bellingham-based crew partners with Washington suppliers to source premium roofing, siding, windows, and decking materials—ensuring rapid delivery and local support. We deliver transparent bids, manufacturer-backed warranties, and community-focused service, guaranteeing every exterior 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—coordinating roofing, siding, windows, and decking to work in harmony against moisture 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 at elevation.

Transparent Pricing & Courtesy Rot Repair

At Alpine Siding Pros, honesty is non-negotiable. Rot repair is quoted separately as a courtesy—charged only if needed. Every estimate line-items materials, labor, and any remediation so King Mountain homeowners never face surprise fees. This transparency lets you budget confidently and ensures your exterior project stays on schedule, on budget, and without compromise.

Local Partnerships & Mountain Community Commitment

As a locally owned Bellingham contractor serving King Mountain, we partner with Washington-based manufacturers and suppliers—supporting regional businesses while guaranteeing access to top-quality materials. Our crew lives nearby, understands mountain-specific building codes, and respects the area’s natural beauty. From minor repairs to full recladding, we communicate clearly, adhere to timelines, and treat your property with care—building lasting relationships one home at a time.
