What a DG roof installation includes
We don't just lay shingles. A DG Contracting roof installation is a complete weatherproofing system, installed to GAF specifications from the deck up.
- Tear-off & deck inspection — we remove the old roof and check the decking for rot, soft spots, and inadequate fastening before anything new goes down.
- Ice & water shield at eaves, valleys, and penetrations — critical for stopping ice-dam leaks in our climate.
- Synthetic underlayment, proper ventilation, drip edge, and flashing at every transition.
- Premium shingles or panels plus ridge caps, all installed by our own crews — never day-labor subs.
Every full replacement also comes with a 15-25 year workmanship warranty and downspouts so your new roof drains the way it should.
Roofing materials & options
The right material depends on your home, your budget, and how the roof faces the weather. We'll walk you through all of it during your free estimate.
- Architectural (dimensional) asphalt shingles — our most popular choice. Thicker, longer-lasting, and high wind-rated, with the depth and shadow lines flat 3-tabs can't match.
- Standard asphalt shingles — a reliable, budget-friendly option for sheds, rentals, and simpler rooflines.
- Metal roofing — standing-seam and metal panels shed snow fast, resist hail, and can last 50+ years. Ideal for steep pitches and cabins.
- Flat & low-slope TPO — energy-efficient membrane roofing for additions, porches, and commercial buildings.
Why it matters in the Inland Northwest
Roofs in Spokane and North Idaho take a beating most of the country never sees. We build for the specific failures we watch happen here:
- Snow load — proper fastening and decking so the structure carries a heavy winter without sagging.
- Ice dams & freeze-thaw — ice & water shield and balanced ventilation keep meltwater from backing up under shingles and rotting the deck.
- Wind & hail — impact-resistant materials and wind-rated installation for the storms that roll through every season.
- Hot, dry summers — UV-stable products and ventilation that lets attic heat escape instead of cooking your shingles from below.
A roof installed for a mild climate simply won't last here. Ours are spec'd for the worst week of the year, not the average one.
Our process, start to finish
We keep it straightforward and keep you informed.

- 4. Final walkthrough & warranty registration — we confirm the work meets spec and register your GAF coverage.
Why GAF Master Elite & our 25-year warranty matter here
Fewer than 2–3% of roofers in the U.S. earn GAF Master Elite certification — and DG Contracting is one of them. That status isn't just a badge; it's what lets us offer warranties most contractors can't.
Because we're Master Elite, your roof can be backed by the GAF Golden Pledge, with up to 50-year material coverage and 15-25 year workmanship protection — the strongest residential warranty GAF offers. On top of that, DG adds our own 15-25 year workmanship warranty.
In a freeze-thaw climate, workmanship coverage is everything: most leaks come from how flashing and underlayment were installed, not the shingle itself. See the full details on our warranties page.
