Fort Collins Roof Pros provides professional flat & low-slope roofing in Fort Collins, CO for residential and commercial properties across Northern Colorado. Low-slope sections take hail worse than steep ones, because a stone that glances off a pitched roof lands square on a flat one. Every low-slope specification we write in this city starts from that, and the answer is almost always thickness and a hard layer underneath.
Membrane gauge is the first lever. A 60 mil TPO is a fine roof in a mild climate and a marginal one where inch-and-a-half stones are a normal June event. We spec 80 mil on anything exposed, because the extra mil thickness is the cheapest impact resistance available on a low-slope assembly and it costs a small fraction of what a season of puncture repairs costs.
What sits under the membrane matters as much. Half-inch high-density gypsum or asphaltic cover board over the insulation gives a stone something firm to strike against, so the energy does not drive the membrane into soft polyiso and split it. FM 4473 Class 4 ratings on low-slope assemblies are earned by the whole build-up, not by the sheet alone, and that is the paperwork a carrier wants to see.
Detailing decides whether the roof leaks. Curbs and penetrations get proper flashing rather than pourable sealer, drains get clamping rings and strainers, edges get fastened metal at published spacing, and tapered insulation gets laid to move water to the drain instead of into a ponding low spot that freezes and works the seams. Walk pads go wherever a service technician will stand, because service calls puncture more membranes than weather does.
Coating an old low-slope roof is sometimes right and often oversold. On a sound single-ply with good seams a coating buys years. On a membrane already split from hail it hides the damage from you and from your adjuster, which is a bad trade. We will tell you which one you have before quoting either, and a moisture survey settles the question rather than a guess.
We build and repair low-slope roofs on additions, porch decks, garages and small commercial buildings across Fort Collins, Loveland, Greeley, Windsor, Evans and Wellington. Modified bitumen, EPDM and TPO each have a place here, and we will explain which one your deck, your drainage and your budget point to. We will also tell you which build-up your insurer will actually rate as Class 4.
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 flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing 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.
