What this business does in Burbank, which buildings it works on, how it surveys and prices a job, and the work it will not take on at any price.
We work on houses and small residential buildings in Burbank and the areas around it. That is a deliberate limit: the housing here is a known quantity, and knowing it is most of the job.
Every survey covers the attic as well as the roof, because the entry point and the stain are rarely in the same place. Every job is photographed slope by slope. Every price is against a written scope, with sheathing priced per sheet.

Free inspection, the cool-roof position settled, then a written price.
Tell us the covering, roughly how old, and what prompted the question. Most replacements are scoped from that plus a photograph before anyone travels.
The roof and the attic together. On Burbank's older streets the deck is frequently skip sheathing rather than plywood, and which one you have changes the price before anything else does.
Whether the job crosses half the roof area decides what has to comply with current code. That gets settled before the scope is written, not discovered at inspection.
Covering, underlayment and flashings named. Sheathing priced per sheet. The area left clean and the photographs handed over.
Including ours. There are enough door-knockers working this valley that the checks are worth making on anybody.
California licenses roofing under classification C-39, and the register is public and searchable in about a minute. Ask for the number before the work, not after it.
An overlay is cheaper on the day and hides the deck. If two quotes are thousands apart, this is the first place to look, and it should be written down either way.
Nobody can know how much decking needs replacing before the covering is off. It should be a rate per sheet in the scope, not a lump guess and not a change order.
A fire-rated assembly, a named underlayment and a cool-roof compliant product each move the price. A cheaper quote is sometimes a lesser roof rather than a better price.
A covering can look sound from the sidewalk and be finished at the laps. Insist that the roof and the roof space are both looked at before a figure is written down, ours included. What you should never accept is a number at the door, because a number at the door has to be padded to be safe.
