Why Tekoa businesses need a roof built for this corner of the Palouse
Tucked into the far SE Palouse near the Idaho line, Tekoa sits where the prairie folds up against Tekoa Mountain, and that geography drives the weather right onto your rooftops. Wind funnels down off the high ground, snow loads stack deep through a long winter, and the freeze-thaw cycle works at every seam and fastener until a small gap becomes an open leak.
Commercial buildings here carry their own pressures. A historic small town means a lot of older masonry storefronts with low-slope roofs that were never built for today's snow loads, alongside metal-clad shops and ag structures that take a beating from hail and wind. We assess each one on its own terms rather than handing you a one-size template.
Commercial roofing systems we install and service
We match the membrane or panel to how the building is actually used and what the roof has to shed:
- TPO and PVC single-ply for low-slope storefronts, offices, and retail bays - heat-welded seams that hold up to standing water and ice melt.
- Standing-seam and exposed-fastener metal for shops, warehouses, and farm buildings that need to shed deep snow fast.
- Modified bitumen and built-up systems where a proven multi-ply roof makes the most sense for an older building.
- Flashing, curb, and penetration detailing around HVAC units, vents, and parapet walls, where most commercial leaks actually begin.
Snow, ice dams, and the freeze-thaw problem on flat roofs
Low-slope commercial roofs are where Inland Northwest winters do their quietest damage. Snow that drifts and refreezes against parapets and rooftop equipment forms ice dams that push meltwater back under the membrane. Each freeze-thaw swing then pries that opening a little wider.
We design for it from the start: proper slope to the drains and scuppers, reinforced flashing at every transition, and insulation that limits the warm spots where snow melts and refreezes unevenly. For buildings already showing interior staining, we trace the path back to the source instead of just patching the spot below it.
Working around your business hours
A commercial reroof can't shut a Tekoa business down for a week. We sequence the work so occupied buildings stay usable - phasing sections, protecting interiors and inventory, and keeping entrances and parking clear. For tenant-occupied or multi-use buildings, we coordinate with owners and renters so nobody is caught off guard.
Because we hold licenses in both Washington and Idaho, businesses with locations on either side of the nearby state line can work with one contractor instead of juggling two.
Credentials, warranties, and what they mean for your building
DG Contracting is GAF Master Elite certified, a standing held by only the top 2-3% of roofers in North America, and that lets us register the strongest manufacturer warranties available on qualifying systems. On commercial work we back our installation with a 15-25 year workmanship warranty on top of the manufacturer coverage.
We are fully licensed and insured in Washington and Idaho, so the liability and workers' comp protections are in place before anyone steps on your roof. Want the residential side too? See our roof replacement in Tekoa page for homes and smaller structures.
Inspections, maintenance, and getting an estimate
The cheapest commercial roof is the one you maintain before it fails. We offer scheduled inspections that catch open seams, clogged drains, failing sealant, and storm damage while they're still small repairs. After a wind or hail event, a documented inspection also helps if an insurance claim is in play.
Estimates are free, and we put the scope, system, and timeline in writing so you can budget with confidence. We also offer flexible financing for larger projects. Call (509) 209-1894 to schedule a walk-through of your building.
