Fort Collins Roof Pros provides professional chimney flashing in Fort Collins, CO for residential and commercial properties across Northern Colorado. A chimney is a hole in the roof with a wall built through it, and it is the detail most likely to leak on a house here. It is also a detail hail finds, because a chase cap takes a strike on the flat and dents into a puddle.
Start with the failure people mistake for a roof problem. Tar smeared along a chimney-to-shingle joint is not flashing, it is a countdown. Sealant on a masonry chimney has a service life of a few Front Range winters and then it cracks with the freeze cycle, and the water goes into the wall cavity where it does its work out of sight before it ever reaches a ceiling.
Proper flashing is layered metal with no sealant doing structural work. Step flashing woven course by course up both sides, a base pan at the low side, an apron at the front, and counterflashing set into a cut reglet in the mortar joint rather than lapped over the brick. On a chimney wider than about thirty inches, a cricket to split the water instead of letting it pond behind the masonry.
Kickout at the bottom of the step run is the detail most often missing entirely, and the one that soaks sheathing behind siding. A diverter kicked out to the gutter takes two minutes to install during a reroof and prevents a repair that opens a wall. We reflash rather than reseal, and if the mortar is shot we will say the mason comes before we do, because a reglet cut into crumbling mortar will not hold.
On metal chase caps, we replace thin galvanized with heavier gauge, cross-broken so it sheds instead of ponding, with a drip edge and a proper storm collar around the flue. That is also the part to photograph after a hailstorm, because a dented cap is easy evidence. Cross-breaking means the pan is bent slightly along its diagonals so it cannot hold standing water in the middle.
We reflash chimneys throughout Fort Collins, Laporte, Wellington, Timnath, Loveland, Berthoud and Windsor. If you are reroofing, this is the moment to do it right. Reflashing a chimney later means cutting back into a roof that is already finished. If your chimney is unused, capping and flashing it flat is often cheaper and more durable than keeping a flue nobody lights.
Our licensed and insured team brings the right materials and equipment to every job — UL 2218 Class 4 impact-rated shingles, SBS polymer-modified asphalt, FM 4473 Class 4 rated low-slope assemblies, ASTM D7158 Class H wind-rated shingles, 24-gauge standing seam steel with concealed clips, stone-coated steel with a granulated surface — and backs the work with a written workmanship warranty. We serve Fort Collins and nearby communities including Loveland, Greeley, Windsor, Evans.

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 UL 2218 Class 4 impact-rated shingles, SBS polymer-modified asphalt, FM 4473 Class 4 rated low-slope assemblies, ASTM D7158 Class H wind-rated shingles, 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 Fort Collins 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 Northern Colorado means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Fort Collins Chooses Fort Collins Roof Pros
- ✓We put the Class 4 payback in writing — upgrade cost divided by your carrier's annual premium reduction, in years, before you sign anything.
- ✓Impact-rated accessories are in the base price. Ridge vent, pipe flashings and gutter gauge are the unrated parts that dent, so they get specified with the shingle.
- ✓Tear-off to bare deck as standard. Nobody can inspect sheathing through a second layer, and a roof-over hides the decking problem you will pay for later.
- ✓Manufacturer high-wind nail patterns rather than the four-nail minimum, written into the contract so the wind class on the wrapper means something.
