Most roofing calculators online take a national average and adjust it by ZIP code. This one prices the job the way an estimator would: it separates materials from labor, applies published unit costs from a contractor cost book, and adjusts each for the region — because local labor varies far more than material does.
The output is a range, deliberately. A single number would imply we know things about your roof that nobody can know from a screen: whether the decking underneath is sound, whether there is a second or third layer of old roofing to tear off, what the flashing looks like. A range that admits its own limits is more useful than a precise number that turns out to be wrong.
Your roof is not the same size as your floor plan. Most tools multiply your home's square footage by a fixed factor and call it a roof. On a real San Diego house we measured, that shortcut implied a 2,070 sq ft roof when the actual roof was 1,366 sq ft — a guess that would have quoted about $2,400 too high. An inflated number costs you a contractor you might have wanted; a low one falls apart the moment somebody climbs a ladder.
For San Diego addresses we can measure the roof itself from aerial imagery rather than guessing. How accurate are online roofing estimates? explains the method and, more importantly, what it cannot see.
You are never handed to a crowd. One licensed San Diego contractor, and only when you ask for one — not a list of companies buying your phone number. On roofing, flooring and exterior work, that contractor will match our estimate, apples to apples, meaning identical scope.
Outside San Diego you can still use the calculator and keep the number. We just won't pretend to have a contractor for you yet.
