A complete system, not just a layer of shingles
Roof installation is more than nailing down shingles. On a new build or a full tear-off near Comstock, we install the entire GAF roofing system as the manufacturer designed it: starter course, ice-and-water shield at the eaves and valleys, synthetic underlayment, properly nailed architectural shingles, ridge cap, and balanced intake-and-exhaust ventilation. Each piece protects the next, which is what keeps a South Hill roof watertight through decades of freeze-thaw.
Because we're GAF Master Elite certified, a credential held by only the top 2-3% of roofers nationwide, we can register your installation for the GAF Golden Pledge warranty covering both materials and workmanship for 25 to 50 years.
Built for new construction and additions
The South Hill keeps growing, and new homes and additions need a roof installed right the first time. We coordinate with builders and homeowners on bare-deck installs where there's no existing roof to match or work around. That means we can dial in the deck inspection, drip edge, flashing and ventilation from scratch rather than retrofitting around someone else's shortcuts.
For additions on existing homes around Lincoln Heights, we match the slope, shingle line and color of your current roof so the new section reads as part of the original house, not a patch.
Respecting steep-pitch and historic rooflines
Many of the historic steep-pitch homes on Spokane's South Hill have dramatic gables, dormers and intersecting valleys that demand careful flashing and an experienced crew. Steep pitches shed snow well but punish sloppy installation, and the complex geometry creates more valleys and penetrations where water wants to get in.
We install step flashing at every wall, woven or closed-cut valleys done to spec, and pipe boots and chimney flashing that actually seal. The result looks true to the home's character while performing like a modern roof.
Engineered for Inland Northwest winters
South Hill roofs face heavy snow loads, ice dams and wind-driven rain. A good installation anticipates all of it.
- Ice dam defense: ice-and-water membrane along eaves and valleys where meltwater backs up under refreezing snow.
- Ventilation balance: matched intake and exhaust to keep the deck cold and reduce the snow-melt cycle that forms ice dams.
- Wind resistance: correct nailing patterns and rated shingles to hold up to gusts that funnel across the hill.
These details rarely show up in a quick estimate, but they're the difference between a roof that lasts and one that leaks by its third winter.

Every roof we install on the South Hill comes with our 15-25 year workmanship warranty on top of the GAF material warranty. Replace your roof with us and we'll include up to a 15-25 year workmanship warranty, so your drainage and roofing work together from day one.
