The work beneath a 17-plane roof
The homeowner called for a roof replacement in Salem. The measurement report described 2,151 square feet of roof across 17 planes, with steep main slopes and smaller sections at different pitches. The wood beneath the shingles also needed attention: plywood required replacement.
Plywood before the finished surface
The crew replaced plywood as part of the roof work. The progress photographs show exposed framing beside replacement sheets, followed by new plywood along a lower roof section. These views record a stage that the finished shingles would cover.
Different slopes, connected details
The report measured a predominant 12/12 pitch, with smaller 4/12 and 6/12 sections. It also recorded 71 linear feet of valleys and 114 linear feet of ridges and hips. These measurements helped describe the roof shape and plan materials; they did not establish the condition of concealed wood.
The new Charcoal shingles
Kodiak installed GAF HDZ shingles in Charcoal. The photographs show the new shingle slopes and ridge, along with the progression from exposed decking to underlayment. The roof replacement took two days and was completed on October 6, 2026.
The Roof, In Numbers
The report's measured dimensions and material estimates are listed separately below. The shingle examples show both no waste allowance and a 14% allowance for cuts and waste; neither is an installed quantity. One roofing square is 100 square feet.
| Roof surface area | 2,151 sq ft |
|---|---|
| Roof size | ~22 squares |
| Roof planes / facets | 17 |
| Predominant pitch | 12/12 — 12 inches of rise per 12 inches of run |
| Other pitches | 4/12 and 6/12 |
| Eaves / rakes | 203 / 149 linear ft |
| Ridges / hips | 69 / 45 linear ft |
| Valleys | 71 linear ft |
| Plywood in quote | 20 sheets of ½-inch CDX (quoted) |
|---|---|
| Shingle estimate, no waste allowance | ~66 bundles |
| Shingle estimate, 14% waste allowance | ~75 bundles; ~2,452 sq ft of coverage |
| Starter / drip-edge coverage | ~353 linear ft |
| Leak-barrier coverage | ~612 linear ft |
| Ridge / hip cap coverage | ~114 linear ft |
Ask what happens below the shingles
A roof replacement quote should explain how plywood repairs will be handled as well as which shingles will go on. In Salem, the crew replaced plywood before installing the new shingles. Ask what decking work is included, how additional sheets would be priced, and how you will be shown any concealed conditions before extra work proceeds.
