Flagstaff Roof Pros provides professional chimney & wall flashing in Flagstaff, AZ for residential and commercial properties across Coconino County and the Colorado Plateau. The uphill side of a chimney is a dam, and in Flagstaff it is a dam holding snow rather than rain. Anything wider than roughly thirty inches wants a cricket behind it, and on this side of the state that is not an upgrade item.
A cricket, sometimes called a saddle, is a small framed roof built into the slope above the chimney which splits the flow and routes it around both sides. Without one the chimney's back wall becomes the low point of a pocket, and in this climate that pocket holds a wedge of pack sitting and melting against masonry for weeks after the rest of the roof has cleared.
That is what destroys chimneys here. Mortar joints soak, freeze and spall. Brick faces come off in flakes. By the time it is visible from the driveway the top of the stack has usually lost its crown, and the flashing has spent years working against a wall no longer flat enough to seal against. We have opened chimneys here where the back wall was wet through to the flue.
We frame the cricket, sheath it, run ice barrier across the whole assembly, and flash it as a stepped system with separate counterflashing. Sealant is the backup in that detail rather than the detail itself. Anything relying on a bead of caulk to hold back standing meltwater has a service life measured in a couple of winters. Every winter of standing water is a winter that detail has to survive.
The same reasoning governs every place a roof runs into a wall. A second-story wall above a garage roof, a dormer cheek, a chase around a metal flue. Those intersections are where snow collects, and they are where we find rot once a Flagstaff roof is opened up. Those are also the places a previous roofer most often sealed rather than flashed.
What we will not do is repair your masonry. If brick is spalling and the crown is cracked, that belongs to a mason and we will tell you to hire one, because a perfect flashing detail bonded to a chimney that is coming apart buys you nothing at all. We flash it once, properly, after the masonry is sound again. Order matters here. Mason first, roofer second, and never the other way round.
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 chimney & wall flashing
The difference between chimney & wall flashing that lasts and chimney & wall flashing 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.
