What owners do today

Photos scattered across three crew members' phones.

Measure once, and build every line from it

Every material line on a roof follows from the measurement: squares of shingles and underlayment, feet of drip edge, ridge and valley. Measure once, record the pitch and the layers to remove, and build every line from those figures.

Free roof replacement estimate template

Put the decking clause on every estimate

Nobody can see the decking until tear-off. Price replacement per sheet on the estimate and say that found decking is replaced at that price, so the homeowner agreed before anyone was on the roof.

Write the deposit and the balance in plain words

If you take a deposit, the estimate says how much and when. The final invoice shows the contract price, the deposit received and the balance due, so the homeowner never has to work it out.

Your state may limit how large a deposit can be and how far payments can run ahead of the work. Check before you set them.

Free roof replacement final invoice template

Photograph each layer as it goes down

Tear-off, decking, underlayment, flashing and shingles: a photo of each answers the question nobody can check once the roof is on.

Send the final invoice the day the crew leaves

The job is fresh, the photos are taken and the homeowner is looking at a new roof. That is the day to send it, not the end of the month.

Questions owners ask

Should I show the price per square or one number?

Per square on the estimate. The homeowner sees how the price follows the roof, and a square found later is a simple added line.

What about material ordered and not used?

Say on the estimate whether returned material is credited, and show any credit on the final invoice in plain words.

Can CONSTRUKTR keep the photos with the job?

Yes. The crew takes photos in the phone app as they work, and the photos stay on the job.
