Roofing built around your business, not just your building
A commercial roof is an asset that has to keep working while you do. A leak over a warehouse, retail floor, restaurant, or office isn't just a repair bill — it's lost inventory, closed doors, and frustrated customers. We plan and schedule around your operating hours to keep disruption to a minimum.
Since 2013, DG Contracting has served Inland Northwest property owners as a family-owned, fully licensed and insured contractor in both Washington and Idaho. We work on standalone storefronts, multi-tenant buildings, light-industrial spaces, churches, and the mixed flat-and-sloped roofs common on local commercial properties.
Commercial systems and materials we install
The right membrane depends on your roof's slope, foot traffic, rooftop equipment, and budget. We help you weigh the options instead of pushing one product:
- TPO single-ply membrane — a popular flat-roof choice for its heat-welded seams, reflective white surface that cuts summer cooling costs, and strong resistance to ponding water.
- Flat and low-slope systems — properly detailed for drainage so meltwater and rain move off the roof instead of pooling and freezing.
- Standing-seam and exposed-fastener metal — excellent for shedding our heavy snow loads and a long, low-maintenance service life.
- Architectural and asphalt shingles — for the steep-slope sections of commercial buildings, mansards, and light-commercial structures.
Not sure which system fits? That's exactly what a free estimate is for.
Why the Inland NW climate is hard on commercial roofs
Spokane and North Idaho put roofs through a brutal annual cycle: hot, dry summers that bake membranes and UV-degrade seams, then heavy winter snow loads and relentless freeze-thaw swings.
That movement is where most commercial roofs fail. Water finds a pinhole or a tired seam, freezes overnight, expands, and pries the gap wider — and ice dams back meltwater up under the membrane at the edges. Flat and low-slope roofs are especially vulnerable when drainage and flashing aren't detailed correctly.
We build for that reality: reinforced seams, properly sloped drainage, and flashing details engineered to handle ice, wind, and hail — so small problems don't become structural ones.
Our process — clear, scheduled, and clean
We keep commercial projects predictable from the first call to final walkthrough:
- Inspection & assessment — we evaluate the existing system, decking, drainage, and penetrations, then document what we find.
- Detailed proposal — a written scope and estimate with system options spelled out, so you can budget with confidence. Flexible financing is available.
- Scheduled installation — work sequenced around your business hours, with the site kept tidy and secure throughout.
- Final walkthrough & warranty — we confirm the finished roof with you and register your warranty coverage.
Why GAF Master Elite and a 15-year workmanship warranty matter
DG Contracting is a GAF Master Elite contractor — a credential held by only the top 2–3% of roofers in the country. It requires proven training, licensing, insurance, and a track record GAF stands behind, which means access to the strongest manufacturer warranties available.
On qualifying systems that includes the GAF Golden Pledge material warranty, backed by our own 15-year workmanship warranty. On a commercial roof, workmanship is everything — most failures trace to installation details, not the membrane itself. Our 5.0-star rating across 288 Google reviews reflects how seriously we take that. See the full breakdown on our warranties page.
Repairs, maintenance & emergency response
Not every roof needs replacing. We handle commercial roof repair, seam and flashing fixes, and scheduled maintenance that catches small issues before they shut you down. Routine inspections also help protect your warranty coverage.
When a wind, hail, or snow event causes sudden damage, our emergency response team works to stop water intrusion fast and document the damage for your insurance claim. We also install and service commercial gutters, soffit, and fascia to keep water moving away from the building.
