A full roof system, not just a shingle layer
A roof installation worth doing once is a layered system, and on a new build or a tear-off in this tiny SE Spokane County grain town we install every layer to work together. That means a clean, properly fastened deck, a synthetic underlayment, ice-and-water shield in the valleys and along eaves, balanced intake and exhaust ventilation, and the GAF shingle and accessory line on top.
Skipping a layer to shave the bid is how roofs fail early out here. We build the assembly the way GAF engineers it, which is also what keeps the long-term warranty intact.
Built for open Palouse exposure
Homes and shops on the rolling ground near Rockford sit in open Palouse exposure with very little to slow the wind. A roof here takes uplift across long, unbroken slopes that a sheltered town lot never sees, so edge details do the heavy lifting.
- Sealed and mechanically fastened starter courses at every eave and rake
- High-wind nailing patterns rated well above code minimums
- Metal drip edge and tight rake terminations so wind cannot get a grip under the field
Get the perimeter right on a Waverly roof and the rest of the field stays put through the gusts that roll up off the wheat.
Snow, freeze-thaw, and ice dams
Inland Northwest winters load a roof with heavy snow, then run it through repeated freeze-thaw cycles that pry at any weak seam. Ice dams form when escaping heat melts the underside of the snowpack and the runoff refreezes at the cold eave.
We head that off with continuous ice-and-water membrane at the eaves and valleys, ventilation that keeps the deck cold, and flashing detailed to shed meltwater rather than trap it. On a new install this is the moment to build it in correctly, before the first hard winter tests it.
New construction and outbuildings
Waverly is a working grain community, and the roofs here are not just houses. We install on new homes, additions, garages, shops, and pole-style outbuildings, matching the system to how each structure is used and heated.
An unheated shop ventilates differently than a finished house, and we spec each accordingly. If you are coordinating with a builder, we work to the framing schedule so the dry-in happens on time and the structure is protected the day the deck goes on.
Why homeowners choose DG Contracting
We are a family-owned roofer based in Colbert, holding GAF Master Elite certification that fewer than the top 2-3% of contractors in North America earn. That standing lets us back your installation with a 15-25 year workmanship warranty and register it for the GAF Golden Pledge, with 25- and 50-year manufacturer coverage.
We are licensed and insured in both Washington and Idaho, carry a 5.0 rating across 288 Google reviews, and offer flexible financing. Replace a roof with us and you also get a 15-25 year workmanship warranty. See our roof replacement options if you are weighing a tear-off against new work.
What to expect from estimate to dry-in
It starts with a free, no-pressure estimate. We measure the structure, talk through shingle lines and color, and lay out the full system in writing so you can see exactly what you are buying.
- On-site assessment of the deck, framing, and ventilation needs
- A clear scope and quote with no surprise line items mid-job
- A protected work site and a clean property when we leave
