What Our Roof Replacement & Installation Service Includes
Full Roof Replacement
Full roof replacement means stripping your existing roof down to the deck, inspecting for hidden water damage or rot, and installing a complete new system from underlayment to ridge cap. In Seattle, we regularly see roofs that have endured 25+ years of marine moisture, moss buildup, and the occasional ice dam in neighborhoods like Ravenna and Wedgwood where tree cover keeps things shaded and damp. Our crews document every deck condition with photos, replace any compromised plywood, and install your chosen material to manufacturer specifications so your warranty stays intact. We back every full replacement with our written 90-Day Done Right Promise - if it’s not right, we come back and make it right, no paperwork, no arguing.
New Construction
New construction roofing is the installation of a complete roof system on a home being built from the ground up, starting with a clean deck and no legacy problems to hide. We’ve worked with builders and homeowners across Seattle’s developing areas, from infill projects in Ballard to custom builds on Mercer Island and Bainbridge Island, where proper ventilation and underlayment choices matter even more because there’s no existing structure to reveal past mistakes. Our team coordinates directly with your builder or architect, specifies the right ice-and-water shield for Seattle’s wet winters, and installs flashing details that prevent the leaks we so often get called to fix on other contractors’ new builds. The price we quote is the price you pay - no surprise change orders when the job’s half done.
Asphalt Shingles
Asphalt shingles remain the most common roofing material in Seattle for good reason: they handle our wet climate well, offer strong value, and come in styles that suit everything from Craftsman bungalows in Wallingford to mid-century ramblers in Bryn Mawr-Skyway. We install architectural and three-tab shingles from GAF, CertainTeed, Owens Corning, and other leading manufacturers, and we’re authorized to offer their full warranty coverage because we follow their installation specs precisely, not approximately. In neighborhoods like White Center and Burien where many homes were built in the 1960s and 70s, we often provide our Roof Replacement & Installation in White Center to replace original three-tab roofs with modern architectural shingles that carry 30- to 50-year material warranties. Our estimates include exact shingle counts, not ballpark guesses, so you’re not paying for waste you didn’t need.
Metal Roofing
Metal roofing is a standing-seam or panel system that sheds rain and moss better than almost any material, making it an excellent long-term choice for Seattle’s climate, especially on homes with low-slope sections or heavy tree coverage. We’ve installed metal roofs from Atlas and Tamko product lines across the Seattle area, from contemporary builds in Newcastle to farmhouse renovations in Riverton where homeowners wanted 50+ years of service without another replacement in their lifetime. Metal costs more upfront - typically 2-3 times asphalt - but the lifecycle math often favors it for homeowners who plan to stay put, which describes most of our customers. Our crews are trained in proper thermal expansion detailing and fastener placement, the two places where metal roofs fail when installed by generalists.
Tile Roofing
Tile roofing - clay, concrete, or composite - brings weight, permanence, and distinctive curb appeal to homes that can support the load, which we verify with structural assessment before quoting. We’ve replaced and installed tile on Seattle-area homes from Magnolia’s view properties to the steeper pitches of Kirkland and Inglewood-Finn Hill, where the material’s resistance to rot and insects pays off over decades. Tile requires specialized underlayment because the tiles themselves are not the primary waterproof layer; our crews use proper battens, flashings, and valley treatments that meet Boral and other manufacturer requirements. If your home currently has tile and you’re seeing cracked or slipped pieces after a windstorm, we can match existing profiles and colors rather than pushing a full material change you didn’t ask for.
Flat Roofing
Flat roofing serves low-slope applications - additions, garages, commercial-style residential sections, and modern designs - with membrane systems like TPO, PVC, or modified bitumen that depend entirely on skilled installation for waterproofing. Seattle’s flat roofs take a beating: ponding water from our persistent drizzle, UV exposure during our brief dry summers, and thermal cycling that tests every seam. We install flat systems with proper slope correction, adequate drainage planning, and membrane welding or adhesion that meets manufacturer specs, because a flat roof failure doesn’t announce itself with a missing shingle; it announces itself with water inside your walls. Our inspections include infrared moisture detection where indicated, so we know the condition of what’s beneath before we quote replacement.

Brands We Service for Roof Replacement & Installation
We’re authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines that cover the full range of residential roofing materials available in the Pacific Northwest. With GAF and CertainTeed, we’ve completed hundreds of asphalt shingle installations across Seattle’s established neighborhoods, from Capitol Hill’s vintage homes to the newer construction in Boulevard Park, and we stock the specific underlayments, ridge vents, and starter strips that let us honor their system warranties without substitution. Our Tamko and Atlas experience runs deep on metal and specialty shingle projects where color matching and finish durability matter, particularly on homes in Mercer Island and Bellevue where HOA guidelines restrict material choices.
Whether you have GAF Timberline HDZ already specified by your architect, a CertainTeed Landmark requirement from your insurance settlement, or an older Boral tile roof that needs section replacement to maintain uniformity, we can help. We don’t substitute materials without written approval, we don’t install “equivalent” products that void your warranty, and we register every eligible installation with the manufacturer so your coverage is real, not theoretical. If you’re not sure what brand is on your roof now, we’ll identify it during inspection and explain your options without pushing toward the most expensive choice.
Signs You Need Roof Replacement & Installation Right Now
- Your roof is 20-25 years old or older. Most asphalt shingle roofs in Seattle’s climate reach end of useful life around this mark, accelerated by moss retention and moisture cycling. Even if you’re not seeing active leaks, the underlayment and seal strips degrade, and the next windstorm or freeze-thaw cycle can expose the deck beneath. We inspect aging roofs at no charge and give you an honest assessment of whether you’ve got two years left or need action this season.
- You’re finding granules in gutters or downspout outlets. Those granules are the UV-protective coating on your shingles; when they’re washing into your gutters in quantity, your shingles are bald and aging fast. In Seattle’s cloudy climate this can seem less urgent than in Phoenix, but once granules are gone, the asphalt substrate absorbs moisture, swells, and cracks. We document granule loss with photos during inspection so you can see exactly what we’re seeing.
- Shingles are curling, cupping, or missing along edges and valleys. Curling indicates the shingle has dried and shrunk past recovery; missing shingles mean wind has found a lift point and will keep working the edge. Our wet winters make this worse because lifted shingles funnel water directly to the nail line. We replace individual shingles when appropriate, but when the pattern is widespread across a roof plane, replacement is the cost-effective choice.
- You see daylight through the roof boards from inside your attic. This is not a repair situation; this is a roof that has failed structurally or been compromised by long-term leakage. In older Seattle homes, particularly in neighborhoods like Georgetown and South Park where original construction predates modern codes, we find rotted skip sheathing and compromised rafter tails that require structural attention before any roofing material goes on. We address this in our estimate, not as a surprise mid-job.
- Your ceiling has water stains that reappear after “fixing” the obvious leak. Chronic staining means water is traveling laterally under the roofing, often far from where it shows inside. This indicates systemic failure of the underlayment or multiple penetration flashings. Patch repairs in this situation waste money; we explain the full scope, show you the photos, and let you decide with real information. Our 90-Day Done Right Promise means if we miss something, we own it and fix it.
Our Roof Replacement & Installation Process - Step by Step
- 1
Free on-site inspection and photo documentation. We arrive at the scheduled time, in uniform, and climb your roof - we don’t estimate from the driveway or use satellite imagery as a substitute for hands-on assessment. Our technician photographs every roof plane, all penetration flashings, the condition of existing ventilation, and any visible deck issues. You’ll see what we see, and we explain which problems are urgent, which are watchable, and what your options are at each price point.
- 2
Detailed written estimate with line-item pricing. Your estimate specifies materials by manufacturer and product line, quantities based on actual measurements, labor scope including deck repair allowances, and a firm total with no hidden fees. We explain why we recommend what we recommend, and we’re happy to quote alternatives if you want to compare. The number on the estimate is the number on the invoice - a square deal, period.
- 3
Material delivery and job scheduling. Once you approve, we order materials through authorized channels to ensure warranty validity, and we schedule your job for a firm start date with a backup weather date because this is Seattle and rain happens. We coordinate delivery to minimize driveway blockage and protect landscaping. If you live in a neighborhood with parking constraints - Queen Anne, parts of Madrona - we handle the logistics so you don’t have to.
- 4
Tear-off, deck inspection, and installation. Our crew removes old roofing to the deck, inspects every square foot for rot or damage, replaces compromised plywood, and installs your new system to manufacturer specifications with proper underlayment, ice-and-water shield at eaves and valleys, and ventilation that meets code. A foreman checks each phase before we proceed, and we photograph key details for your records and our warranty file.
- 5
Final inspection, cleanup, and warranty registration. We walk the completed roof, verify fastening patterns and flashing details, clean every speck of debris from your property with magnetic sweepers for nails, and present your final documentation including manufacturer warranty registration and our written 90-Day Done Right Promise. Then we follow up at 30 and 90 days to confirm satisfaction - not because we expect problems, but because standing behind our work is how we’ve stayed in business since 2016.
How Much Does Roof Replacement & Installation Cost in Seattle?
A typical asphalt shingle roof replacement in Seattle runs $12,000-$20,000 for an average 2,000-square-foot home, while architectural shingle upgrades or complex rooflines push toward $22,000-$28,000. Metal roofing generally starts around $25,000 and can reach $45,000+ for standing-seam systems on larger or steeper homes. Tile replacement ranges $20,000-$40,000 depending on whether structural reinforcement is needed. Flat membrane systems vary widely by access and slope correction requirements, typically $8,000-$18,000 for residential applications.
Several factors move these numbers: roof pitch (steeper = more labor), number of penetrations and valleys, deck condition requiring plywood replacement, accessibility for material delivery, and whether we’re removing one layer or multiple previous roofs. The cheapest bid rarely accounts for these variables honestly; we’ve been called in after low bidders “discovered” $6,000 in extra charges that should have been foreseeable.
To avoid overpaying, get at least two estimates that include the same scope, verify your contractor carries proper insurance and manufacturer authorization, and ask specifically what’s not included. Our estimates include all labor, materials, permits, disposal, and cleanup - the price we quote is the price you pay. We also offer a Free Second Opinion on Any Written Estimate if you’ve already got a quote that raised questions.
Every estimate is free, in-home, and no-obligation. Call (866) 850-9676 to schedule.
