Roofing built for Millwood's commercial footprint
Millwood is a compact city, and its commercial stock reflects that history - a mix of older masonry storefronts, mid-century light-industrial bays, and small offices serving the surrounding established neighborhoods. Many of these flat and low-slope roofs were last redone decades ago, and the membranes are now brittle from years of Inland Northwest sun and cold.
We work on the building types Millwood actually has: single-story retail along the Argonne Rd corridor, repurposed warehouse space near the river, and multi-tenant strips where one roof covers several businesses at once. That mix calls for a roofer who can scope each section honestly rather than selling one product for every situation.
Flat and low-slope systems we install
Commercial roofs in Millwood rarely look like the steep residential roofs nearby. They demand membrane and metal systems engineered to shed water with very little pitch:
- TPO and PVC single-ply - reflective, heat-welded seams that hold up to the temperature swings between a 95-degree July afternoon and a January freeze.
- Modified bitumen - a durable, layered choice for older buildings where tear-off and recover decisions matter.
- Standing-seam and architectural metal - for sloped commercial sections and entry canopies that take wind off the river valley.
- Coatings and restoration - extending the life of a sound deck before a full tear-off becomes necessary.
We match the system to your building, your budget, and how long you plan to hold the property.
Why snow, freeze-thaw, and ice dams matter on a flat roof
Flat does not mean low-risk in this climate. Snow piles deep on Millwood rooftops and sits there, and the daily freeze-thaw cycle drives water into every seam, fastener, and parapet flashing that has loosened over time. Ponding water that freezes overnight is one of the most common reasons a commercial membrane fails early.
On low-slope roofs near the Spokane River, ice can also back up at drains and scuppers, forcing water sideways under the membrane. Our installations prioritize positive drainage, reinforced flashing details, and the kind of seam work that keeps meltwater moving off the roof instead of pooling on it.
Minimizing disruption to your business
A roof replacement on an occupied storefront is different from a vacant house. We stage materials to keep your parking and entrances usable, schedule the loudest work around your hours where we can, and keep the active tear-off area sealed against weather each day so an afternoon Spokane Valley storm never reaches your inventory or your customers.
For multi-tenant buildings, we coordinate access so neighboring businesses stay open. You get a clear timeline before we start, not a surprise once the crew is on the roof.
Warranties and credentials that protect the investment
DG Contracting holds GAF Master Elite status, a certification carried by only the top 2 to 3 percent of roofing contractors in the country. For commercial clients that translates into access to the GAF Golden Pledge warranty (25 and 50-year coverage) on top of our own 15-25 year workmanship warranty.
We are licensed and insured in both Washington and Idaho, carry the documentation your insurer and lender will ask for, and offer flexible financing so a necessary roof does not have to wait on a single capital cycle. If your project also touches gutters, we include a 15-25 year workmanship warranty. See our commercial roofing services for the full scope.
A local company with 288 five-star reviews
We are a family-owned business that has worked across the Spokane Valley since 2013, and our 5.0 rating across 288 Google reviews comes from property owners who needed straight answers and crews that showed up. Millwood's older established neighborhoods sit right alongside its commercial blocks, so the building you manage is often a few minutes from homes we have already roofed.
That proximity matters: when a leak shows up after the next freeze, we are not driving in from another county to look at it.
