Roof size and geometry
Larger roofs require more material and labor. Steep slopes, multiple dormers, valleys, penetrations and complex rooflines can increase setup and installation time.
Material system
Asphalt shingles, standing-seam metal and other systems have different material, accessory and labor requirements. Even within one category, product tiers and installation systems vary.

☎ 603-633-1712Tear-off and existing conditions
Removing old roofing, disposing of debris and correcting damaged decking can materially change project cost. Hidden deck problems may not be visible until the existing covering is removed.
Flashing, ventilation and details
Chimneys, skylights, wall transitions, valleys, vents and roof edges can add scope. Proposal comparisons should identify whether old flashing is reused, replaced or rebuilt.
How to compare estimates
Compare the written scope line by line rather than only the total. Ask what is excluded, how unforeseen deck repairs are priced, what cleanup is included and which manufacturer system components are specified.
