Flagstaff Roof Pros provides professional roof replacement & substrate repair in Flagstaff, AZ for residential and commercial properties across Coconino County and the Colorado Plateau. A Flagstaff tear-off gets priced twice. Once for the covering you can see from the driveway, and once for the sheathing nobody can see until that covering is in a dumpster. We put a number on both before we start.
There is a licensing limit behind that second number which most homeowners never hear about. Arizona's roofing rule, written into the administrative code at R4-9-103, lets a roofer replace up to ten percent of the total roof substrate square footage when bad decking turns up after the contract is signed. Past ten percent the work has to go to another license.
That line gets crossed here more than it does lower down. Water standing on a deck for a week does modest damage. Water that soaks in, freezes, pushes the plies apart, thaws and soaks in again does it to the same square foot dozens of times between November and April. What we usually find is delamination at the panel edges rather than soft rot in the middle.
So our bids carry a stated allowance in sheets, a per-sheet price beyond it, and the name of the contractor who takes over if the bad area runs past the cap. You approve any overage in writing before more roof gets opened. Nobody finds out about a five-figure change order while standing in the driveway. The allowance is not a guess, either. We set it from what the attic showed us before you signed anything.
If your house wears cedar shakes, read this before you plan anything. The city struck sections R905.7 and R905.8, wood shingles and wood shakes, out of its residential code entirely, and struck the matching sections from the commercial code as well. In the largest contiguous ponderosa pine forest on the continent, you cannot legally re-roof in wood. That holds whether your shakes are failing or merely tired, and it is worth knowing before you budget.
What goes back on is a Class A or Class B assembly, because those are the only two fire classifications the city left standing. Architectural asphalt gets there. Steel gets there in a listed assembly. Self-adhered membrane gets there on the low-slope sections. We will price each one over a deck we have actually looked at, and we will not pretend to price one we have not.
Our licensed and insured team brings the right materials and equipment to every job — Class A and Class B roof assembly listings, self-adhering polymer modified bitumen low-slope sheet, a sixty pound per square foot ground snow load adopted by ordinance, roof substrate replacement capped at ten percent of the deck, plumbing vent stacks terminated twelve inches above the covering, ice barrier underlayment carried past the interior wall line — and backs the work with a written workmanship warranty. We serve Flagstaff and nearby communities including Doney Park, Kachina Village, Timberline-Fernwood, Fort Valley.

Materials, equipment and how we do roof replacement & substrate repair
The difference between roof replacement & substrate repair that lasts and roof replacement & substrate repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A and Class B roof assembly listings, self-adhering polymer modified bitumen low-slope sheet, a sixty pound per square foot ground snow load adopted by ordinance, roof substrate replacement capped at ten percent of the deck, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Flagstaff job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Coconino County and the Colorado Plateau means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Flagstaff Chooses Flagstaff Roof Pros
- ✓Every estimate cites the City of Flagstaff amendment it is built to, and the amended pages come stapled to it rather than quoted from memory.
- ✓We state a sheathing allowance in sheets and a price beyond it, because a roofing license stops at ten percent of the deck and yours may run past it.
- ✓We measure plumbing vent stack heights before chasing a winter leak, since the city requires twelve inches and a short stack explains a great many of them.
- ✓Anything laid between October and April is hand-sealed under every tab, to the manufacturer's cold-weather sheet, which we hand you with the invoice.
