Seattle, WA Metal Roofing: Stunning Black Interlock Shingle Roof Transforms 1929 English Tudor Home
Seattle, WA
Susan and Richard A.
When my husband Richard said he wanted to put a metal roof on this 1929 English Tudor house, I thought he had gone around the bend, maybe several bends.
After seeing the pictures and hearing about the features, I started to become a convert. Now that the job is down, I know that we made the right decision for several reasons.
First, the black Interlock shingles look so appropriate on this house. In certain lights it even appears to look like <a title="slate" href="” data-wpil-keyword-link=”linked”>slate. Many neighbors and friends have commented on how very attractive it looks,
Secondly, the workmen did such a professional job. They were meticulous at each step of the process and, we are confident, that their craftsmanship was excellent. Each day that they were here they worked diligently and conscientiously making sure that every step of their work was done to the highest expectations. In addition, they were quiet and tried not to interrupt our daily routine.
Third, we are most pleased about all the high quality features of the product: the durability, the appearance, and the fact that it is maintenance free.
Thank you for making the excellent product.

Top 10 Metal Roofing FAQs for Homeowners in Seattle
Homeowners researching metal roofing in Seattle often have several important questions before replacing their roof. Many people want to understand how metal roofing compares to traditional materials like asphalt shingles in terms of lifespan, durability, cost, and long-term value. Roofing decisions can also be influenced by local weather conditions. Homes in Seattle may experience environmental factors such as rain, wind, snow, heat, fire, or seasonal storms that can impact roof performance over time. The following frequently asked questions help explain what homeowners should know when evaluating metal roofing and why many people choose durable roofing systems designed for long-term protection.
How long will a metal roof last in Seattle, WA?
Metal roofs in Seattle commonly last 40–70+ years; asphalt roofs typically have shorter lifespans (often 15–30 years depending on product and installation). Seattle’s temperate, maritime climate brings long, wet winters and mild summers, with persistent precipitation and coastal moisture that keep roofs damp much of the year. Frequent rainfall and marine humidity encourage moss and organic growth on shaded roof surfaces and can accelerate corrosion on low-quality materials, while snow loads are generally low compared with inland regions—so moisture resistance and algae/moss resistance are key longevity factors in this market. Homeowners choose metal for durability, low maintenance, and superior water-shedding. Interlock Metal Roofing systems use heavy‑gauge aluminum and include a lifetime limited 50‑year transferable warranty for long‑term protection.
How much does it cost to install a metal roof in Seattle, WA?
In Seattle, WA, metal roofs generally cost more up front than asphalt shingles but can deliver greater long‑term value. Final price varies with roof size, pitch and complexity (ridges, valleys, dormers), whether an old roof must be torn off, flashing and skylight work, and local labor rates. Seattle’s permitting, seasonal weather windows, access challenges on steep or tree‑lined lots, and contractor availability can also influence cost. Many homeowners compare options by lifetime value—durability, energy performance, and reduced maintenance can lower future repair and replacement expenses compared with cheaper systems. Durable metal roofing systems often reduce long‑term costs through longer service life and fewer repairs. Interlock Metal Roofing emphasizes long‑term ownership value and product performance rather than competing as the lowest‑cost roofing option, focusing on systems designed to minimize lifetime expenses and maximize protection for Seattle homes.
Should I choose metal roofing or asphalt shingles for my Seattle home?
Short answer: Metal roofing can be worth it in Seattle if you prioritize longevity and low long‑term risk; homeowners who want durability and long‑term protection often choose metal.
Lifespan: Metal typically lasts multiple decades longer than asphalt, which often needs replacement sooner. Maintenance: Metal requires less routine repair and resists rot; asphalt demands more inspections and periodic shingle replacement, especially where moss and algae thrive from constant moisture and shade in the Puget Sound region. Durability: Metal sheds rain, resists wind and freeze‑thaw damage better than asphalt in Seattle’s wet, coastal climate, reducing leak risk over time. Long‑term value: higher upfront cost for metal often pays off in lower lifecycle costs and fewer repairs.
Interlock Metal Roofing appeals to homeowners seeking long‑term performance and architectural curb appeal because it combines durable metal construction with designed aesthetics and warranty-backed systems.
Are metal roofs noisy when it rains in Seattle?
This is a common myth: metal roofs are noisy in Seattle rain. Modern residential metal roofs installed over continuous, solid decking do not sound like barn roofs. Rain noise is influenced by the full roof assembly—insulation, attic volume, underlayment, and attachments all reduce sound. Installation quality and proper fastening prevent rattles and vibration. Properly installed residential metal roofing is typically similar in sound to asphalt or tile during rain. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes, with underlayments and flashing that help control water, thermal performance, and sound. In short, a well-installed metal roof in Seattle is not noticeably louder than other common roofing materials.
How energy-efficient are metal roofs in Seattle?
In Seattle’s mild, maritime climate a metal roof can be energy-efficient because metal surfaces (especially with reflective coatings) can reflect sunlight and reduce summer heat gain. Actual performance depends on the full roof assembly: underlayment, attic insulation, and proper ventilation all influence heat transfer and moisture control. In cooler, cloudy Seattle summers the cooling savings may be smaller than in hot, sunny regions, but reflective finishes still help on bright days and improve year-round durability. Homeowners researching roof replacement often consider energy efficiency to lower utility bills, improve indoor comfort, reduce moisture risk, qualify for incentives, and increase resale value. Interlock Metal Roofing systems are designed to support long-term home performance.
How does metal roofing in Seattle, WA withstand wind, hail, and severe weather?
Seattle, WA roofs face frequent heavy rain, periodic windstorms/atmospheric rivers, and occasional hail or snow that can stress roofing systems. Metal roofing performs well in wind (low uplift when properly fastened), sheds heavy rain and snow, and many metal profiles resist hail and impact better than asphalt shingles. Performance depends on: roofing system design; installation quality; material durability. Homeowners factor weather resilience into material choice to protect the structure, reduce leakage and repair costs, and lower insurance/maintenance risk. Interlock Metal Roofing systems are engineered for durability, hail protection, and wind resistance and—when specified and installed correctly—offer long-term resilience suited to Seattle’s wet, windy climate.
Will a metal roof rust or corrode in Seattle's wet climate?
Metal roofing performance in Seattle, WA depends on the metal type: steel, copper, zinc, and aluminum each behave differently. Some metals (e.g., stainless steel, copper, zinc, aluminum) are inherently more corrosion-resistant than uncoated carbon steel. Aluminum performs especially well in wet or coastal environments because it naturally forms a protective oxide layer and resists saltwater-driven corrosion. Homeowners should prioritize corrosion resistance to avoid leaks, staining, structural degradation, higher maintenance and replacement costs in Seattle’s damp climate. Interlock Metal Roofing Systems use aluminum construction engineered for strong corrosion resistance and are protected further by the Alunar Coating System for extra protection against moisture and salt exposure. This extends roof longevity and helps preserve resale value.
How often should I inspect and maintain my metal roof in Seattle?
Metal roofing in Seattle is generally low maintenance and highly durable, resisting rot and insect damage common in the Pacific Northwest. However, no roof is completely maintenance-free: periodic inspections—after storms and seasonally—are important. Check for accumulated debris on panels and in valleys, clean gutters to prevent backflow, and inspect flashing, sealants and roof penetrations (vent pipes, chimneys, skylights) for corrosion, loose fasteners or seal failure. Weather events and seasonal debris like heavy branches, moss or salt spray can cause localized wear or block drainage. Promptly addressing damage and keeping drainage clear preserves performance and warranty. Overall, metal is a long-lasting, low-maintenance option well suited to Seattle’s wet, changeable climate.
How does curb appeal affect my home's resale value in Seattle?
In Seattle, metal roofing can increase home value because buyers often prioritize durable, low-maintenance roofs that reduce future repair and replacement costs. Premium roofing materials also boost curb appeal, making homes stand out in competitive neighborhoods. A long lifespan conveys reliability and can improve buyer confidence at inspection and appraisal. Architectural style matters — roofs should complement the character of local neighborhoods and historic districts. Interlock Metal Roofing systems provide multiple architectural profiles to match varied tastes, including slate, cedar shingle, Mediterranean tile, shake, and standing seam, and are offered in heavy-gauge aluminum and solid copper. Properly specified and installed metal roofs that fit neighborhood style typically add marketability and can command higher offers in Seattle’s real-estate market.
Can I install solar panels on my Interlock Metal Roofing System in Seattle?
Yes — Interlock Metal Roofing Systems are compatible with solar installation with the installation of custom solar brackets installed by Interlock Metal Roofing (PNW) Inc. Seattle’s cool, wet, coastal climate brings frequent rainfall and persistent moisture that promotes moss growth and keeps roofs damp—factors that favor long‑lasting, low‑maintenance roofing choices. Because solar is a long‑term investment that adds weight, roof lifespan is important; plan for future solar when replacing a roof. Homeowners comparing materials in Seattle should prefer durable, corrosion‑resistant, low‑moss roofs—Interlock systems are solar‑compatible and designed to support secure mounting solutions.
