Boulder Roof Pros provides professional roof coatings & sealing in Boulder, CO for residential and commercial properties across the northern Front Range. Roof coatings and sealing get sold around Boulder as the cheap alternative to a new roof. Sometimes that is exactly right. Often it is a way of paying for the same repair twice, and the difference comes down to one thing: whether the assembly under the coating is dry.
A silicone or acrylic coating is a monolithic membrane, and it needs a sound, dry substrate to bond to. Sprayed over wet insulation, it traps that moisture beneath a vapor-tight skin where freeze cycles pull the whole thing apart from below. The roof looks new for one season, then blisters and delaminates in a map of exactly where the water was. Silicone will not bond to a chalked or dirty surface, so preparation is most of the labour.
So the sequence matters. Infrared scan or core samples first, wet insulation cut out and replaced, seams and flashings repaired, then coat. On a dry, well-drained membrane with sound laps, silicone adds real service life and tolerates standing water far better than acrylic does, which counts for a lot where meltwater sits at a low point for weeks. Wet mil thickness is checked with a gauge rather than estimated by counting buckets.
Coatings also have a temperature window. Most systems want surface temperatures above roughly 50 degrees and rising, with no dew or frost, which gives us a working season from about May into September. We will not spray a roof in late October to close out a budget year, because it will not cure properly and you will own the result, not us. A coating applied too late in the season looks finished and behaves like paint.
Where coatings genuinely earn their keep here: aged metal roofs with sound panels and tired fasteners, where seam tape plus a coating stops capillary leaks without a tear-off; and sound modified-bitumen roofs where reflectivity and a few more years are the actual goal rather than waterproofing something that has already failed. On a house that usually means a garage or shop roof rather than the main dwelling.
Sealants are the smaller half of this work and the more abused. We use butyl and polyurethane where each belongs, and we do not caulk a flashing failure. If a joint moves seasonally — and at this elevation most of them do — it needs metal detailed to allow that movement, not a bead of sealant that gets scraped out and redone every second spring.
Our licensed and insured team brings the right materials and equipment to every job — self-adhering ice barrier run 24 inches inside the wall line, baffled continuous soffit intake vents, ridge exhaust balanced to a net free area of one to 300, blown cellulose over an air-sealed ceiling plane, clamp-on snow guards and continuous snow fences, site-built chimney crickets and reglet-cut counterflashing — and backs the work with a written workmanship warranty. We serve Boulder and nearby communities including Longmont, Louisville, Lafayette, Superior.

Materials, equipment and how we do roof coatings & sealing
The difference between roof coatings & sealing that lasts and roof coatings & sealing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with self-adhering ice barrier run 24 inches inside the wall line, baffled continuous soffit intake vents, ridge exhaust balanced to a net free area of one to 300, blown cellulose over an air-sealed ceiling plane, 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 Boulder 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 northern Front Range means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Boulder Chooses Boulder Roof Pros
- ✓We open the attic on every roof call, because most winter leaks in this county start above the ceiling rather than on the shingles.
- ✓Ice barrier and ventilation are priced into a replacement from the start, not sold as an upsell once the deck is open.
- ✓We measure existing soffit intake before quoting a ridge vent, since exhaust without intake pulls warm air out of the house.
- ✓Snow retention is laid out over doors, walkways and gas meters before any metal panel goes on the roof.
