What a deck-up installation actually involves
A new roof is not just the shingles you can see from the street. The part that decides whether your roof lasts twelve years or thirty is the layered system underneath, and a real installation rebuilds all of it in order.
We strip the old roof to the bare decking, replace any sheathing that snow and freeze-thaw cycles have softened, then build back up - ice-and-water shield at the eaves and valleys, synthetic underlayment over the field, starter course, then the roofing material, finished with matched ridge cap and flashing. Each layer has a job, and skipping or rushing one is what causes the leaks that show up two winters later.
Material options for Valley homes and buildings
Spokane Valley's housing runs from older homes near Sullivan Rd to newer construction in Greenacres, alongside the light-commercial buildings clustered around Mirabeau and Trent. We install the right system for each:
- Architectural asphalt shingles - the everyday choice for Valley homes; dimensional, wind-rated, and available in impact-resistant grades for hail-exposed lots
- Standing-seam metal - sheds heavy snow on its own and shrugs off hail, a strong fit for steeper newer pitches
- Flat and low-slope TPO - heat-welded membrane for additions, garages, and the light-commercial structures along Trent where shingles do not belong
We bring samples to your estimate and explain the real cost-and-lifespan trade-offs on the spot.
Engineered for how the Valley weathers
A roof off Sullivan Rd faces a specific set of stresses, and we install to meet each one rather than to a generic national minimum:
- Snow load - we confirm the decking and fastening can carry accumulated weight without flexing
- Freeze-thaw and ice dams - membrane placement at the eaves plus balanced attic ventilation keep meltwater from backing up under the roofing
- Wind and hail - high-wind nailing patterns and impact-rated material options for the open exposures near the river
Ventilation deserves special mention here. An attic that runs too warm melts the snow above it unevenly, and that refreeze at the cold eave is exactly how ice dams form. Getting intake and exhaust balanced is part of every install we do, not an upsell.
How DG runs the job
Our crews are our own - the team that tears off your old roof is the team that finishes the new one, so nothing gets lost in a handoff to subcontractors. Every project opens with a written scope that lists the material, underlayment, flashing, and ventilation plan so you know exactly what you are paying for.
As a GAF Master Elite contractor, a level fewer than three percent of roofers in the country hold, we install GAF systems to the manufacturer's exact specification, which is what makes the strongest warranties available to you. If a full system is more than your roof needs right now, our roof repair in Spokane Valley page covers when a targeted fix is the smarter call.
Warranty, gutters, and financing
We stand behind the installation with a 15-25 year workmanship warranty, and qualifying GAF systems are eligible for the GAF Golden Pledge with 25- and 50-year coverage on materials and labor - among the most complete protection in roofing, and only available through Master Elite installers.
Replace your roof with us and you also get a 15-25 year workmanship warranty, because managing runoff is part of protecting the roof you just invested in. We are licensed and insured in both Washington and Idaho, offer flexible financing, and every estimate is free.
