01 Job details
Who and where
Your name, the job address and the market. The market sets the labor rate and the code checks.
Market drives the Title 24 cool-roof check (2025 code, re-roof table §150.2(b)1I). Zones are approximate — LA and San Diego span multiple zones; pull the zone by address from the CEC map near any boundary.
Enter your roof sections below (or sketch them), pick a roof system, and your installed price range updates as you go. Your first estimate needs no sign-up.
02 Roof sections
Measure the roof
Each roof plane's footprint and pitch, or sketch it. Squares and waste are worked out for you.
Enter each roof plane's footprint (measured flat, as from above). Pitch converts it to true surface area automatically.
03 Roof system
Pick the roof
The product line sets the installed price per square. The range on the right updates as you go.
04 Tear-off & disposal
What comes off
Existing layers and access. Not sure? Leave the defaults and it is confirmed on site.
CA tear-off runs $1–3/sf ($100–300/sq). Tile tear-off is the high end; add deck repair at $2–5/sf where the deck is bad.
Not sure how many layers are up there? Leave it at 1 — we confirm on site.
05 Scope & margin Contractor
Add-ons, financing and contingency
Lines on top of the roofing priced above. The homeowner never sees these controls.
The $/sq prices are all-in — tax stays at 0 so the quote outputs the book price. Enter a rate only for a line that is priced pre-tax.

All prices are editable ballpark defaults — set them to your supplier quotes.
