Steep-Pitch Roof Replacement

A full tear-off on a 47-square steep-pitch roof
This Shawnee homeowner contacted McCann's Roofing and Construction for a complete roof replacement on a large brick and stone home with a 10/12 pitch and a cut-up, multi-section roofline. The crew removed the existing roofing material down to the decking, re-nailing any loose wood before dry-in and shingle installation.
The QuickMeasure numbers explain the labor on this one: 47.7 squares, 205 linear feet of hips, and 166 linear feet of valleys. Hips and valleys outnumbered ridge more than four to one, which means far more cutting, more starter, and more precise detail work than a simple gable roof of the same size.
Roofing scope
A GAF shingle system in Weathered Wood
Every layer of this roof was installed to spec, with the details this home called for:
- Full tear-off down to the decking; loose wood re-nailed
- Self-adhering ice and water shield at all penetrations and valleys
- Synthetic underlayment across the full deck
- New embossed drip edge in Weathered Wood along all eaves and rakes, 433 linear feet
- GAF ProStart starter shingles along all gutter lines and rake edges
- GAF Timberline Natural Shadow lifetime dimensional shingles in Weathered Wood, 6-nail installation for the highest wind rating
- GAF Z-Ridge hip and ridge shingles in Weathered Wood
- 8 GAF Master Flow high-capacity 144-style dome vents to keep the manufacturer warranty intact
- 4 new pipe flashings and 4 vent caps (3"–5"), all color-matched to the shingles
- Full job site cleanup and a 5-year workmanship warranty
Installation in progress as GAF Timberline Natural Shadow shingles are installed on rear elevation, Shawnee, OK.
Measured for an exact material fit
McCann's orders a satellite QuickMeasure report on every project so materials are ordered to the exact dimensions of the roof, not a rough estimate. This roof's hip-and-valley-heavy design drove significantly more linear footage than a simple roofline of the same square count.
What made this job different
Steep pitch, heavy hips, and 92 feet of step flashing
A 10/12 steep pitch
At 10/12 the roof rises 10 inches for every 12 inches of run. Every crew member works harnessed, materials have to be staged deliberately, and the pace is slower than a walkable roof.
371 feet of hips and valleys
205 linear feet of hips and 166 of valleys against just 82 feet of ridge. That ratio means constant cutting and fitting rather than long straight runs.
92 feet of step flashing
Where the roof meets vertical wall, step flashing gets woven in course by course. This home had 92 linear feet of it, plus 38 feet of additional flashing detail.

Common questions
Questions about this project
What color is GAF Weathered Wood?
Weathered Wood is a warm, multi-toned blend of tan, brown, and gray designed to mimic aged cedar shake. It pairs naturally with brick and stone exteriors and is one of the most widely installed GAF colors on Oklahoma homes.
What is GAF Timberline Natural Shadow?
Timberline Natural Shadow is GAF's lifetime dimensional shingle, built with a shadow band that gives the roof depth and a wood-shake appearance. It carries a lifetime limited warranty when installed to specification.
Why does a 10/12 pitch add to the cost of a roof?
A 10/12 pitch rises 10 inches for every 12 inches of horizontal run, steep enough that crews must work harnessed, materials must be staged rather than simply set down, and installation moves at a slower pace. Those added labor and safety requirements are what a steep pitch fee reflects on an estimate.
Why install 8 roof vents on one home?
Vent count is sized to the attic's square footage and its intake, not chosen at random. On a 47-square roof, 8 high-capacity dome vents provide the exhaust needed to keep the attic balanced and the manufacturer's shingle warranty intact. undersized ventilation is one of the most common reasons a warranty claim gets denied.
