Built around the businesses near Manito Park
Comstock is a working neighborhood as much as a residential one. The small medical offices, salons, churches, and service businesses tucked among the established homes off Grand Boulevard and around Manito Park all sit on roofs that take the same beating South Hill houses do, but with far more at stake when water gets in. A leak over a waiting room or a stockroom is not just a repair bill, it is closed doors and lost days.
We schedule commercial work around how a business actually runs, staging materials so your parking and entrances stay usable and keeping crews coordinated so the loud, disruptive phases land when they cost you the least. As a family-owned company working here since 2013, we treat a Comstock storefront roof the way we would treat the one over our own shop.
Flat and low-slope systems we install
Most commercial buildings in and around Comstock run flat or low-slope decks, which fail differently than the steep shingle roofs on the surrounding homes. Ponding water, seam separation, and flashing failures around HVAC curbs are the usual culprits. We install and service the membranes that hold up in the Inland Northwest:
- TPO and PVC single-ply for reflective, heat-welded seams that resist standing water and UV.
- Modified bitumen for multi-layer durability on older low-slope decks.
- Built-up roofing where a proven, redundant system makes sense.
- Metal for low-slope sections and architectural accents that shed snow cleanly.
We also rebuild tapered insulation to correct drainage on decks that have always ponded, so water moves to the drains instead of sitting through the next freeze.
What South Hill weather does to a commercial deck
The mature tree-lined streets that make Comstock so pleasant also drop leaves and needles that clog scuppers and internal drains every fall. Once a drain backs up, the next snowfall sits as a load on the membrane, then melts and refreezes into ice at the edges and seams. That cycle is what opens a TPO seam or splits an aging bitumen lap.
Wind-driven rain finds tired flashing around parapet walls and rooftop units, and hail leaves bruising you cannot see from the ground. We inspect the details that fail first, the drains, the curb flashings, the wall terminations, and tell you plainly whether you are looking at a targeted repair or a system at the end of its life.
Repair, restoration, or replacement
Not every commercial roof needs to be torn off. When the membrane is sound but tired, a fluid-applied coating or restoration can add years and stop minor leaks for a fraction of a full rebuild. When the deck is saturated or the system has cycled past its service life, replacement is the honest answer, and we say so.
We walk every option with the building owner or property manager, including how each choice affects warranty coverage and insurance. If you also own or rent out a home in the neighborhood, our residential roofing in Comstock covers the steep-slope side of the same address.
Warranties, licensing, and financing
DG Contracting is a GAF Master Elite contractor, a credential held by only the top 2 to 3 percent of roofers in North America, and we are licensed and insured in both Washington and Idaho. Commercial installs are backed by our 15-25 year workmanship warranty alongside the manufacturer's material coverage, so the building is protected against both product and installation failures.
We offer flexible financing to spread the cost of a larger commercial project, and every assessment starts with a free, no-pressure estimate. You will get a written scope that spells out exactly what we are doing and why.
