What is a roofing square?

A square is 100 square feet of roof surface, so a 2,800 sq ft roof is 28 squares. Shingles and labor are commonly priced per square.

How much extra material should I order?

Add a waste factor for cuts, starter courses and ridge. Simple roofs need less and roofs with many valleys and hips need more. Your supplier can confirm the factor for your shingle and the roof shape.

Should a roofing proposal include a warranty?

State two things separately: the manufacturer's warranty on the shingles, and your own workmanship warranty with its length in years. Only promise what you will honour.

Roofing proposal template

A homeowner buying a roof is comparing three quotes that look the same and are not. This template makes yours easy to compare: priced by stage and by the square, with the underlayment, flashing and decking allowance written out, so the client can see what a cheaper quote left out.

Terms

Payment: 30% on signing to order materials, and the balance on completion and the final walkthrough.
Revisions: Decking repairs beyond the allowance are priced per sheet and confirmed with you before the work continues.
Additional terms: Shingles carry the manufacturer's warranty; state the workmanship warranty you offer and for how many years. The work depends on dry weather and the dates may move. Permits are pulled by the contractor where required.

How to scope and price it

Quote by the square, which is 100 sq ft of roof, and show the count (28 here). The client can check your measurement against another contractor's.
Write the decking allowance with a per-sheet price. Rotten sheathing is only visible after tear-off, and a stated price removes the argument.
List the small parts: flashing, vents, pipe boots and ridge cap. They are what separates a roof that lasts from one that leaks at the chimney.
Say what the crew does with the debris. A magnetic nail sweep is a small line that clients remember.

The terms, and why

A 30% deposit orders the materials, the largest cost, and the balance is due on completion once the client has walked the job. The weather language protects both sides: a roof cannot be opened in rain, so the dates are estimates and the client is told so at signing. Keeping the manufacturer's warranty and your workmanship warranty separate shows the client who stands behind what.

Measuring in squares

Common waste ranges, not rules. Confirm with your supplier for the product and the roof.

Hip roof	about 12 to 15%	Hips and ridges add cut pieces
