A roof that starts at the deck, not the shingle
Plenty of installs treat the shingle as the product and everything underneath as an afterthought. We build the other way around. On a new install in Marshall we start by inspecting and re-securing the sheathing, then layer on a synthetic underlayment, ice-and-water membrane at the eaves and valleys, properly spaced fasteners, and a balanced intake-and-exhaust ventilation path before a single shingle is set.
That sequence is what separates a roof that lasts its full rated life from one that quietly fails at the seams a decade early. For new construction especially, getting the layers right the first time means you never inherit someone else's shortcut.
Built for wind off the prairie
Homes in this rural-residential stretch southwest of Spokane sit on open ground, and the wind off the prairie hits a roofline with nothing to slow it down. Gusts that a tree-sheltered city lot never feels will work at lifted tabs and under-nailed shingles until they peel.
We install to GAF's high-wind nailing pattern as a baseline here, not as an upgrade - six fasteners per shingle, sealed starter courses at every rake and eave, and ridge caps rated to stay put. The goal is a roof that treats a prairie windstorm as a non-event.
Snow load, freeze-thaw, and ice dams
The Inland Northwest stacks heavy snow on a roof for weeks at a time, then runs it through repeated freeze-thaw cycles. Meltwater refreezes at the cold eave and backs up under the shingles as an ice dam.
- Ice-and-water shield at the eaves and in every valley, carried well past the interior wall line.
- Balanced ventilation that keeps the deck cold so snow melts evenly instead of refreezing at the edge.
- Drip edge and flashing detailed to move water off the roof and away from fascia.
On a new build this is the difference between a roof that sheds a hard winter and one that stains ceilings by its second February.
Why GAF Master Elite matters on a new install
Fewer than three percent of roofing contractors in the country hold GAF Master Elite status, and DG Contracting is one of them. On an installation that distinction is not a sticker - it is what lets us register your roof for the GAF Golden Pledge warranty, the strongest coverage GAF offers, with 25- and 50-year terms on materials and workmanship.
We pair that with our own 15-25 year workmanship warranty, so the system and the labor behind it are both standing behind your home. If you are weighing materials and ventilation options, our roof replacement page walks through the same system in a tear-off context.
