What We Do

Every Surface of Your Home's Exterior

Clark County's wet winters and Gorge-corridor wind events are hard on every surface. We replace, restore, and protect your home with certified materials and crews who know exactly what Pacific Northwest conditions demand.

Roof Replacement

If your roof is past 20 years, has active leaks, or is showing moss and granule loss. It's not a patch job. Our Malarkey-certified replacements strip to the deck, assess for rot, and install a complete moisture-management system built for 40+ years in the Pacific Northwest climate.

Window Replacement

Drafty windows and single-pane glass are a direct line to a higher heating bill in a Pacific Northwest winter. Our ProVia window replacements eliminate air infiltration, cut energy costs, and upgrade your home's look. We install to manufacturer spec, so your warranty stays fully protected.

Siding Installation

Wood and vinyl siding fail in the Northwest: they warp, crack, and trap moisture against your sheathing. James Hardie fiber cement is engineered for exactly this climate: moisture-proof, pest-resistant, and fire-rated. As a Hardie Preferred Remodeler, we install it with the extended warranty that only certified contractors can offer.

Deck Building

Pressure-treated wood decks in the Northwest require constant maintenance and typically fail in 10–15 years. Fiberon composite decking is designed for our climate: no sanding, no staining, no rot, no splinters. We build decks that look great and outlast the pressure-treated alternative by decades.

Door Replacement

A drafty entry door or sticking patio door isn't just inconvenient. It's a direct energy leak. Our ProVia door replacements seal against Pacific Northwest weather with fiberglass and steel entry doors, patio doors, and storm doors built for decades of performance in Clark County's climate.

Gutter Installation

Clark County receives 40+ inches of rain annually. Gutters that overflow, sag, or fail at joints put your foundation, siding, and fascia at risk. We install seamless aluminum gutter systems fabricated on-site and sized for actual Pacific Northwest rainfall volumes. No joints along the run, no seam maintenance cycle.

Patio Covers

Clark County averages 144+ rainy days per year. A quality patio cover turns your outdoor space into year-round living: solid aluminum, insulated panels, open lattice, and attached roof-tie designs built for Pacific Northwest weather. Stop losing outdoor days to drizzle.

Why Product Selection Matters Here

Southwest Washington and the Portland metro create a demanding exterior environment: long wet seasons, persistent moisture, shaded areas, seasonal temperature changes, and strong UV exposure during dry summer periods. The manufacturer partners we work with were selected because their products are engineered for these specific conditions.

Factor 1

Moisture Management

Drainage design, flashing integration, material moisture absorption, and ventilation all determine how long an exterior system performs before maintenance is required.

Factor 2

Seasonal Movement

Materials that expand and contract with temperature and moisture cycling stress seams, fasteners, and joints. Installation details — gap tolerances and fastening patterns — determine how well a system handles this over time.

Factor 3

UV and Weather Exposure

Dry-season UV exposure degrades surface finishes and coatings. The wet-winter/dry-summer cycle tests paint adhesion and material stability in ways that single-season climates do not.

Factor 4

Maintenance Profile

Different material systems have meaningfully different maintenance requirements over 10–30 years. The right product selection reduces ongoing cost and attention, not just upfront installation cost.

Our Manufacturer Certifications

Five factory certifications — Malarkey Emerald Premium, James Hardie Preferred, ProVia Authorized, TimberTech, and Fiberon. Each one requires verified installation training that protects your product warranty.

What Homeowners Say

Real Reviews from Real Neighbors

"We had Left Coast replace our 22-year-old roof after a wind event took off several shingles. The crew showed up exactly when they said they would, completed our 2,400 sq ft roof in a day and a half, and did a magnetic sweep of the whole yard before leaving. The Malarkey shingles look incredible and we've been through two major rain events since without a single issue."

"Left Coast replaced all 14 windows in our 1987 Camas home with ProVia units and the difference in our heating bills has been genuinely shocking. Our last two heating bills are down more than 20% compared to last year. The install was clean and fast. They even repaired some dry rot around two of the window frames without trying to upcharge us into a bigger project."

"I hired Left Coast to replace the James Hardie siding on my 1960s Portland ranch. The quote process was the most transparent I've seen. Left Coast was the only contractor who walked me through every line item and explained why each product choice made sense for my house. The finished install looks exceptional and the project manager checked in daily."
