Missoula Roof Pros provides professional chimney flashing in Missoula, MT for residential and commercial properties across the Missoula valley and the Bitterroot. We build a cricket behind chimneys narrower than the code requires one on, and we do it because a chimney in this valley acts as a dam for two months rather than for a single afternoon. Twenty-four inches of width is our trigger. The building code waits until thirty.
A cricket is a small peaked structure framed onto the upslope side of the chimney that splits what comes down the roof and sends it around both sides. Without one, the back wall of the masonry stops everything arriving from above, and the pile that forms there is the single most reliable leak on any roof in this town. We find it more often than we find worn shingles.
The code threshold is a perfectly reasonable national compromise, written for places where that pile drains away within a day or two. Here it stands for weeks against the mortar joints under continuous pressure, freezing at night and softening in the middle of a bright afternoon. A twenty-six-inch chimney with no cricket is not a code violation. It is still going to leak.
The flashing itself gets built in two pieces, always. One piece of step metal per shingle course, each turned up against the brick, and then a second layer of counterflashing let into a groove ground out of the mortar joint and sealed. One-piece surface-mounted flashing caulked to the brick is common on older Missoula houses and it is a five-year detail at best. Sealant against masonry does not survive many winters up here.
We also look at the brick, not just the metal. Chimneys here run all heating season and take real thermal cycling, and a joint that has lost its mortar will take on water regardless of how good the flashing is. If the crown is cracked or the joints are open, we will say plainly that the mason should come out before we do.
One last thing worth mentioning in this town. If a wood stove flue passes through the roof, that penetration sits in the warmest column of air on the house and clears its own snow, so it looks fine from below. Check the storm collar and the high-temperature sealant every fall anyway. They dry out fast up there, and a clear penetration tells you nothing about the condition of its seal.
Our licensed and insured team brings the right materials and equipment to every job — a self-adhered ice barrier run two courses up the shaded slopes, rigid baffles set in every rafter bay ahead of any vent product, hidden gutter hangers screwed into rafter tails at sixteen inches, a cricket framed behind chimneys narrower than the code trigger, skylight curbs built ten to twelve inches tall for sustained depth, overflow scuppers cut through the parapet above the primary drain — and backs the work with a written workmanship warranty. We serve Missoula and nearby communities including Lolo, Orchard Homes, East Missoula, Bonner-West Riverside.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with a self-adhered ice barrier run two courses up the shaded slopes, rigid baffles set in every rafter bay ahead of any vent product, hidden gutter hangers screwed into rafter tails at sixteen inches, a cricket framed behind chimneys narrower than the code trigger, 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 Missoula 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 the Missoula valley and the Bitterroot means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Missoula Chooses Missoula Roof Pros
- ✓We price the shaded slopes and the sunny slopes of your roof separately, because in this valley they are not carrying the same winter
- ✓Our inspection season is late September and October, not spring, because a roof here stops being available in December and a spring finding has already cost you a season
- ✓We quote winter leaks as two visits with two numbers, and we will not charge you for a permanent repair that we know cannot cure in a cold pool
- ✓Before we quote a metal panel we walk the ground underneath it, because the whole load releases at once here and the planning belongs below the roof rather than on it
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Missoula follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
