Why Harrison businesses call us first
Harrison is a working lakeside community, not a strip-mall sprawl. The buildings that keep this town running - the shops feeding cyclists off the Trail of the Coeur d'Alenes, the seasonal restaurants on the waterfront, the storage and light-industrial structures set back from the lake - each carry a roof that has to survive Inland Northwest winters with no room for downtime.
DG Contracting LLC has been roofing North Idaho and Eastern Washington since 2013. We hold an active Idaho contractor license alongside our Washington credentials, so commercial work on the east shore of Lake CdA is handled by a crew that's properly insured on both sides of the state line. As a GAF Master Elite contractor - a rating fewer than 3% of roofers in the country reach - we can warrant systems most local outfits simply can't offer.
Commercial roof systems we install
The right membrane depends on your building's slope, foot traffic, and how it's used. We assess and install:
- TPO and PVC single-ply - heat-welded seams for flat and low-slope roofs over retail, restaurant, and office space; reflective surfaces that ease summer cooling loads.
- EPDM rubber membrane - a durable, cost-effective choice for larger flat decks and outbuildings.
- Modified bitumen - layered, redundant protection for roofs that take ponding or mechanical wear.
- Standing-seam and architectural metal - for steep-slope commercial buildings and mixed-use structures where snow shedding matters.
- GAF commercial shingle systems - for pitched roofs on storefronts and lodging that want a finished, residential-grade look.
Not sure which fits your property? A free estimate starts with us on your roof, not guessing from the ground.
Built for snow load, ice dams, and freeze-thaw
A flat or low-slope commercial roof in this region faces a punishing cycle. Heavy snow piles on the deck, daytime melt runs toward drains and parapets, then it refreezes overnight - the freeze-thaw pattern that pries seams open and lifts flashing year after year.
We detail every commercial install around these realities: proper drainage and tapered insulation so meltwater leaves the roof instead of pooling, reinforced flashing at curbs and penetrations, and ice-dam protection where roof planes meet walls. Done right, the system carries the snow it's supposed to and stays watertight through every thaw.
Repair, recoat, or replace
Not every commercial roof needs to come off. When you call us, we tell you honestly which path makes sense for the building and the budget:
- Repair - targeted fixes for storm damage, failed seams, punctures, or flashing leaks when the membrane still has life.
- Restoration and recoat - extending a sound single-ply or metal roof with a seamless coating that buys years before a full tear-off.
- Full replacement - a new system, properly warranted, when the existing roof is past saving.
For a town where a leak over the kitchen or the cash register means lost revenue, we schedule around your operating hours and keep the building usable while we work.
Warranties and financing for commercial owners
Every commercial project is backed by our 15-25 year workmanship warranty, and qualifying GAF systems can carry the GAF Golden Pledge coverage - 25- and 50-year protection that most contractors aren't even authorized to write. That matters when you're protecting an asset you plan to hold, lease, or sell.
We also offer flexible financing so a roof replacement doesn't have to wait for the slow season, and replacement projects include a 15-25 year workmanship warranty.
A local crew that answers the phone
Harrison is a small lake town, and we treat it like one. You deal with the same family-owned company from estimate through final walkthrough - no call centers, no subcontracted strangers showing up unannounced. Our 5.0 rating across 288 Google reviews comes from owners who got straight answers and a roof that held up.
