Seattle, WA
Thomas D.
I want to express my appreciation for your company’s excellent response to our recent need for replacement of deteriorating closure material on our metal roof installed about four years ago. It is a pleasure to deal with people whose first priority is customer satisfaction.
I’d like to particularly thank Steven Jasper, the installer responsible for the work. He was competent, efficient and thorough. It was a large job and particularly difficult because of its height off the ground as well as the <a class="wpil_keyword_link" title="hot" href="” data-wpil-keyword-link=”linked”>hot weather. I also want to thank Wendy Willans of your customer service department who arranged for the work effectively and promptly.
I will not hesitate to recommend your company to anyone interested in a high quality metal roofing installation by people eager to stand behind their products and workmanship.

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 commonly last 40–70+ years; asphalt roofs typically last about 15–30 years. Seattle’s climate—frequent rain, coastal moisture, mild wet winters with occasional snow, and persistent humidity that promotes moss growth—can shorten thin or poorly detailed roofs but favors metal’s resistance to rot and biological growth. Homeowners choose durable metal systems to avoid repeated asphalt replacements, reduce maintenance (moss removal, shingle failure), and better resist rain- and wind-driven wear. Proper gauge, corrosion‑resistant coatings, quality flashings, and correct fasteners are critical in Seattle’s coastal, rainy environment; hail and heavy wind are less common but considered in designs. Routine maintenance—clearing gutters, removing debris and moss, and inspecting sealants and flashings—helps reach the upper end of metal’s lifespan. Interlock Metal Roofing uses heavy‑gauge aluminum and a lifetime limited 50‑year transferable warranty for long‑term protection.
How much does it cost to install a metal roof in Seattle, WA?
Metal roofs in Seattle typically cost more upfront than asphalt shingles. Final price depends on roof size, slope and complexity, tear-off and number of layers, flashing and skylight work, and labor. Local construction factors—permit fees, Seattle-area labor rates, access and weather-related installation needs—also influence cost. Many homeowners compare roofing options by lifetime value rather than initial price: metal roofs generally offer greater durability, fewer repairs, and a longer service life, which can reduce total long-term repair and replacement expenses. Choosing a durable system can lower maintenance, insurance, and replacement costs over decades. Interlock Metal Roofing focuses on long-term ownership value and durable systems rather than competing solely as a low-cost roofing option, helping Seattle homeowners balance upfront cost with lifetime performance.
Should I choose metal roofing or asphalt shingles for my Seattle home?
Metal roofing vs asphalt shingles in Seattle — Lifespan: metal 40–70+ years; asphalt shingles 15–30 years. Maintenance: metal is low (occasional inspections); shingles need more frequent repairs, moss removal and periodic replacement. Durability: metal resists rot, moisture and wind uplift and sheds heavy rain; asphalt is more vulnerable to moss, granule loss and water infiltration in Seattle’s wet, humid winters. Moss thrives on shaded, persistently damp roofs, accelerating shingle failure risk. Long-term value: metal has higher upfront cost but lower lifecycle cost and often better resale for owners focused on longevity. It’s not always best for every budget or aesthetic. Homeowners who prioritize durability and long-term protection often choose metal. Interlock Metal Roofing systems appeal to those homeowners because their interlocking panels shed coastal moisture, resist moss and wind uplift, and deliver lasting performance with strong architectural curb appeal.
Are metal roofs noisy when it rains in Seattle?
This is a common myth: modern residential metal roofs installed over solid decking do not sound like barn roofs. Roof sound depends on insulation, attic space, and the overall roof assembly—adding underlayment, insulation and a ventilated attic greatly reduces rain noise. Installation quality matters: fastener type, secure flashing and continuous deck contact prevent vibration and noise. Properly installed residential metal roofs are typically similar in sound to asphalt or tile roofs during rain. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes, including components that control water, airflow and acoustics. In short, when designed and installed correctly, metal roofing in Seattle will not be noticeably noisier than other common roof types.
How energy-efficient are metal roofs in Seattle?
Metal roofing can be energy efficient in Seattle. Many metal roofs have reflective coatings that reduce solar heat gain by reflecting sunlight, lowering summer cooling needs. However, true energy performance depends on the entire roof assembly — underlayment, insulation level and placement, and attic ventilation — which determine heat transfer and moisture control. Seattle’s temperate, maritime climate with mild, often cloudy summers and cool, wet winters means reflective benefits are smaller than in hot, sunny regions but can still improve comfort and reduce peak cooling loads. Homeowners replacing roofs often weigh energy efficiency to lower utility bills, improve year‑round comfort, extend roof and HVAC life, 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 roofs face heavy seasonal rain and atmospheric rivers, plus frequent strong wind and occasional hail from summer storms. Metal roofing performs well in wind—interlocking panels and mechanical fastening can resist high gusts when engineered to local codes. In hail, heavier gauges and high-profile profiles reduce denting and leaks; impact performance varies by alloy, thickness and finish. Metal sheds rain quickly and resists rot and moss common in Seattle’s damp climate, reducing leak risk during storms. Performance depends on roofing system design, installation quality and material durability. Homeowners consider weather resilience to limit water intrusion, lower repair and insurance costs, and extend roof life. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance, but proper design and installation are essential for peak performance.
Will a metal roof rust or corrode in Seattle's wet climate?
In Seattle’s wet, often coastal climate, corrosion and rust resistance are key when choosing a metal roof. Metal roofing performance depends on the base metal—steel, copper, zinc, and aluminum each behave differently—so some materials resist corrosion better than others. Aluminum performs particularly well in wet or coastal environments because it naturally forms a protective oxide layer that slows corrosion and won’t rust like steel. Homeowners should consider corrosion resistance to avoid premature deterioration, reduce maintenance and repair costs, and protect home value in humid or salty air. Interlock Metal Roofing systems use aluminum construction designed for strong corrosion resistance and are further protected by the Alunar Coating System for extra protection, making them a durable option for Seattle homes.
How often should I inspect and maintain my metal roof in Seattle?
Metal roofing is generally low maintenance and highly durable, making it a strong choice for Seattle’s wet, windy climate. However, no roof is completely maintenance-free. Homeowners should inspect roofs periodically—after storms and at least seasonally—for loose fasteners, damaged seams, or worn sealants. Remove leaves, needles, and branches that trap moisture; keep gutters clear to prevent back-up; and inspect flashing and roof penetrations (vents, chimneys, skylights) for proper seals. Heavy seasonal debris or storm damage can accelerate wear or cause leaks, so prompt cleanup and repair after events is important. With routine visual checks and minor care, metal roofs provide long-lasting, low-maintenance protection in the Pacific Northwest.
How does curb appeal affect my home's resale value in Seattle?
Yes—metal roofing can increase home value in Seattle. Buyers often prioritize durable, low‑maintenance roofs that withstand Pacific Northwest weather, and a premium roof improves curb appeal. A long lifespan and proven resistance to rot, moss, and wind can boost buyer confidence and potentially raise resale value or shorten time on market. That said, architectural style matters: a metal roof that complements a neighborhood’s character and home style will be more valuable than a mismatched look. Interlock Metal Roofing systems offer multiple architectural profiles—slate, cedar shingle, Mediterranean tile, shake, and standing seam—available in heavy‑gauge aluminum and solid copper, giving homeowners weather‑resistant options that suit varied Seattle streetscapes. Consult a local appraiser or real estate agent for neighborhood‑specific estimates.
Can I install solar panels on my Interlock Metal Roofing System in Seattle?
Q: Can solar panels be installed on Interlock Metal Roofing Systems in Seattle?
A: Yes. Interlock Metal Roofing Systems are solar compatible—Interlock Metal Roofing (PNW) Inc. supplies custom solar brackets that securely mount panels to their metal profiles. Seattle’s long, wet seasons and high humidity encourage moss growth and prolonged moisture exposure, so roofing and mounts should resist corrosion and avoid trapping water. Roof lifespan is important when adding solar: long-lasting materials reduce the chance of removing panels for reroofing. Homeowners comparing materials in Seattle should favor long-lasting metal roofing over short-lived shingles to minimize moss-related maintenance. Interlock systems are designed to support solar mounting solutions.
