Six Things That Move Your Roof Estimate
The calculator handles the big-picture inputs. These are the line items that show up on a written estimate and explain why one roof costs more than another.
Pitch & access
Steeper roofs and tight access mean more labor, scaffolding, and safety setup. A 12/12 pitch costs noticeably more per square than a 6/12.
Tear-off layers
Each existing layer adds disposal weight and crew time. Two layers is more than twice the work of one.
Decking repair
Soft or rotted plywood under the old shingles needs replacement. Charged per sheet — we show you the bad sheets before we replace them.
Material grade
Architectural asphalt is the baseline. Designer profiles, Class 4 impact-rated shingles, or synthetic slate/shake step the price up significantly.
Ventilation & flashing
Ridge vent, soffit vent intake, step flashing, chimney flashing, and pipe boots are non-negotiable on a properly built roof — and they’re part of the estimate.
Roof complexity
Valleys, dormers, skylights, and unusual ridge lines all add labor. A simple gable runs less than a complex hip-and-valley with three dormers.
Roof Calculator Questions

It’s a strong ballpark for Northern NJ. Real numbers from real jobs we install — but every house has its quirks. The final written estimate sits inside the range based on what we measure on-site.
Steeper roofs require more setup, slower install, and stricter safety harnessing. A 12/12 takes about twice the labor hours of a 6/12 for the same square footage.
Use the size of your house footprint as a rough guide — most single-family roofs are 1.2× to 1.5× the home’s square footage depending on pitch and overhangs. Or just call us and we’ll measure it for you for free.
Decking repair is the most common one — we charge per sheet of plywood and only after we show you the bad spots. Chimney flashing rebuilds, skylight replacements, or unusual structural issues are also priced separately and disclosed before the work.
Yes. As an Owens Corning Preferred Contractor, we register every OC roof for the Preferred Protection Limited Warranty at no extra charge. Other manufacturers’ standard warranties are also included as part of the install.
