Metal Roof Replacement Seattle: Commercial, Residential
Seattle gets close to 150 rainy days a year. That long wet season can keep shaded roof areas damp for extended periods, especially on north-facing slopes and heavily wooded properties, and this moisture wears down asphalt shingles faster than in drier climates. Metal roofing has a smoother surface, which makes moss and algae buildup less likely compared with shingle roofs across Seattle’s older neighborhoods.
Metal roofing systems last 40 to 70 years. Asphalt shingles typically last 15 to 20 years in this climate, often less on roofs with heavy tree cover or north-facing slopes that stay shaded and wet. That gap is why more Seattle homeowners and business owners are switching to metal on their next roof replacement.
As a local metal roof replacement company, we replace residential and commercial metal roofs throughout Seattle, Washington. Every installation follows the Washington Building Code and the standards enforced by Seattle’s Department of Construction and Inspections. Our crews account for the wind patterns off Puget Sound, the region’s wet season, and the Douglas fir and cedar debris that collects on roofs near wooded lots.
Our Metal Roof Replacement Services
As a metal roof replacement contractor serving Seattle, we handle full tear-offs, deck repairs, and new panel installations. A typical project moves through roof inspection, material selection, permit review where required, tear-off, deck repair, underlayment installation, panel installation, and a final inspection before the crew leaves the site.
Each roof replacement project includes underlayment rated for Pacific Northwest moisture levels, step and valley flashing, ridge caps, and a fastening system matched to the panel profile. For roofs in good structural condition, we also offer metal-over-shingle installation, which can lower total project cost by avoiding a full tear-off.
Cost depends on a few factors: roof size, material choice, whether a tear-off is needed, roof complexity, and how accessible the roof is for the crew. Before any work begins, we provide a written scope of work covering panel type, gauge, color, and total cost, so Seattle homeowners and property owners know what they’re paying for ahead of time.
Residential Metal Roof Replacement Seattle
Seattle’s residential housing stock includes a mix of early-1900s craftsman bungalows, Tudor and colonial-style homes, mid-century ramblers, newer townhomes, and multi-unit duplexes. Housing conditions vary by neighborhood: Ballard’s older craftsman homes deal with marine moisture off the water, Queen Anne’s homes often have steeper roof pitches that need careful panel layout, West Seattle properties tend to sit on tree-covered lots with more wind exposure, and Capitol Hill’s historic homes usually require a roofing profile that matches the original architectural style.
As residential metal roofing installers, we work on single-family homes, townhomes, condominiums, duplexes, and historic homes where roof pitch and architectural detail need to be matched carefully. Standing seam and metal shingle panels are common choices for homeowners who want a metal roof that still fits a traditional or craftsman-style exterior.
A typical residential roof replacement project takes one to three days, depending on roof size, pitch, and how much of the old roofing material needs to be removed. We schedule around the homeowner’s timeline and clear debris from the property each day the crew is on site.
Metal roofing also reflects heat rather than absorbing it, which can reduce cooling costs during Seattle’s warmer months. In this climate, though, the bigger advantage for residential properties is resistance to sustained rain, wind, and moss buildup rather than heat reflection.
Commercial Metal Roof Replacement Seattle
Commercial properties in Seattle range from retail storefronts and office buildings to warehouses, restaurants, industrial facilities, and multi-family apartment complexes. Flat and low-slope commercial roofs in this region take on standing water during the rainy season, which makes seam quality and drainage design critical to a commercial roof replacement project.
As commercial metal roofing specialists, we work with property managers, business owners, and building owners across Seattle to plan replacements that minimize disruption to daily operations. Larger commercial buildings are often replaced in phases, allowing the business to continue operating during construction.
Standing seam panels with a hidden fastener system are a common choice for Seattle commercial properties, since concealed fasteners reduce exposed screw points that can loosen or corrode under repeated wind and rain cycles.
Metal Roofing Options for Replacement
Different metal roofing materials perform differently in Seattle’s wet, mild climate. Below is a breakdown of the main options we install, with the most commonly requested materials covered in the most depth.
Standing Seam Metal Roofing
Standing seam panels use a concealed fastener system, with vertical seams that interlock adjacent panels. Hidden fasteners keep screws out of direct weather exposure, which matters in Seattle, where fasteners are exposed to rain for most of the year.
Standing seam panels are typically rated for wind speeds above 140 mph in manufacturer testing, well beyond the wind loads seen around Puget Sound. It’s the material we install most often on both residential and commercial roof replacements across Seattle.
Corrugated Metal Roofing
Corrugated panels use a wave-pattern ridge for added structural rigidity. In Seattle, this style shows up often on garages, detached shops, sheds, and some older residential and agricultural buildings on the city’s outskirts.
Corrugated roofing uses exposed fasteners, so periodic fastener checks are part of routine maintenance, especially after Seattle’s windier winter storms.
Metal Shingle Roofing
Metal shingles are formed to resemble traditional shingle or slate patterns while providing the lifespan of steel or aluminum. This option suits Seattle homeowners in craftsman or traditional-style homes who want a metal roof that doesn’t change the home’s original look.
Metal Shake Roofing
Metal shake panels replicate the look of wood shake shingles, which are still common on older Seattle homes, without the moisture absorption that wears down real wood shake over repeated wet seasons.
Metal Tile Roofing
Metal tile panels mimic clay or concrete tile profiles at a fraction of the weight, which means less structural reinforcement is needed on the existing roof deck compared to real tile.
Sheet Metal Roofing
Sheet metal roofing uses large, flat panels with minimal seams, a straightforward option for Seattle workshops, utility buildings, and smaller commercial structures.
Galvalume Roofing
Galvalume is steel coated with a combination of aluminum and zinc. The aluminum content resists corrosion from Seattle’s near-constant moisture, while the zinc protects cut edges and scratches from rusting.
Galvanized Roofing
Galvanized roofing is steel coated in zinc through a hot-dip process, a long-standing, cost-effective option for residential and outbuilding roofs across the Seattle area.
Aluminum Roofing
Aluminum roofing resists corrosion without a protective coating, since aluminum doesn’t rust the way untreated steel does. It holds up well in Seattle’s damp, marine-influenced climate, where moisture exposure is constant for much of the year.
Copper Roofing
Copper roofing develops a natural patina over time, shifting from bright copper to a green-gray finish, and some copper roofs remain functional for over 100 years, which suits Seattle homeowners restoring historic properties.
Steel Roofing
Steel roofing offers strength and wind resistance at a lower cost than aluminum or copper. Most steel roofing installed in Seattle includes a protective coating, such as Galvalume or galvanized zinc, to prevent rust in a climate where bare steel would corrode quickly.
Tin Roofing
“Tin roofing” is a common term for steel roofing, though true tin roofs are rare today; most products sold under this name in the Seattle area are steel panels with a protective coating.
Zinc Roofing
Zinc roofing is self-healing at the surface, meaning minor scratches oxidize and blend back into the patina over time, a durable option that carries a higher upfront cost than steel or aluminum.
Metal Roofing Replacement Seattle
If you’re searching for a metal roof replacement company near you in Seattle, we serve homeowners and businesses across the city, including Ballard’s marine-exposed craftsman homes, Queen Anne’s steep-pitch roofs, West Seattle’s tree-covered and wind-exposed properties, Capitol Hill’s historic homes, and Fremont and Wallingford’s mix of older and newer housing, along with the broader Washington area. Every project includes a written estimate, a defined timeline, and a crew familiar with local code requirements and Seattle’s weather conditions.
A few signs point to replacement rather than repair: recurring leaks, rust forming around fasteners, loose or shifting panels, failed seams, damaged flashing, and visible corrosion across large sections of the roof. We assess roof condition on-site before recommending replacement over repair, so you’re not paying for a full roof replacement project you don’t need yet.
