Roofing templates
Roofing estimates are usually priced per square (100 sq ft). Breaking out tear-off, underlayment, shingles, flashing and disposal shows the homeowner exactly what they are paying for and reduces disputes about hidden decking repairs.
What to include
- Roof size in squares and the number of layers being removed
- Shingle brand, line and color
- Underlayment, flashing, vents and drip edge
- A per-sheet price for replacing rotten decking, if needed

Frequently asked questions
How are roofing estimates calculated?
Most roofers measure the roof in squares (100 square feet), add a waste factor of about 10–15%, then price tear-off, materials and labor per square. Extras such as decking, chimney flashing and skylights are listed separately.
How should I handle decking replacement I can't see until tear-off?
Add a line with a price per sheet of plywood or OSB and a note that the final quantity will be confirmed after tear-off. That way the homeowner approves the unit price in advance.
