When does a silicone roof coating fit?
We install silicone systems from GE Momentive and Gaco. Gaco coating guidance states its silicone coatings carry no ponding water exclusion, which suits flat roofs that pond.

Commercial roof coatings backed by verified credentials
A commercial roof coating in Denver works hardest against the weather that ages flat roofs fastest. Intense high-altitude sun, rapid temperature swings, hail and freeze-thaw cycles put repeated stress on the surface, seams and flashings. Most of that damage builds out of sight until water shows up indoors.
Sun and heat
Intense sunlight and high surface temperatures age membranes, sealants and exposed flashings faster.
Hail and wind
Storms puncture, crack, loosen or scour roof materials, often where no one looks from the ground.
Freeze-thaw cycles
Water in small cracks and open seams expands when it freezes, and the openings grow.
Standing water
Ponding and blocked drains add weight, trap debris and speed up wear on low spots.
Hidden moisture
A roof can leak long before a stain appears, and the stain is often far from the entry point.
Budget surprises
A leak reaches tenants, inventory and equipment, so the bill is rarely just the roof repair.
I personally was very happy with Apex from start to finish. … The contract was fulfilled over and above my expectations. The crews were, in my opinion, professional.
I own an insurance agency and have been using Apex Roofing for several years. … The owner Mike and my personal contact Brad are very hands-on and have always been available to my clients and myself with any questions or concerns.
It’s a big roof with lots of angles. Apex did an amazing job … Over all I would say it is an easy 5 star job.
Apex Roofing installs silicone and acrylic roof coating systems on commercial and multi-family buildings across Denver and the Front Range, as part of our commercial roofing services in Colorado. The Roof Coatings Manufacturers Association describes coatings as a way to protect and extend the service life of existing roofs, which makes commercial roof restoration an option before a tear-off.
We install silicone systems from GE Momentive and Gaco. Gaco coating guidance states its silicone coatings carry no ponding water exclusion, which suits flat roofs that pond.
We install acrylic systems from Henry and Gaco. The Henry application guide for its acrylic system requires positive drainage, so acrylic suits roofs that shed water well.
Yes, once corroded or damaged panels are replaced, loose rust is removed and loose fasteners are replaced, as the Henry guide requires. The same guide excludes Kynar- and Hylar-coated metal.
We confirm access, safety and the schedule with your property contact first. The Henry guide calls for air intakes to be turned off during application so fumes stay out. Anything beyond the written scope is approved before we do it.
Widespread wet insulation, a failing deck or a membrane past saving call for repair or replacement first. For a new low-slope membrane, Apex Roofing is a Licensed GenFlex applicator (EPDM and thermoplastic roofing).

A commercial roof can be coated when it is dry, sound and compatible with the coating system. Wet insulation, poor adhesion or the wrong drainage for the chosen system rule it out until fixed.
A visual inspection cannot see wet insulation. When our inspection suggests hidden moisture, we recommend the testing the coating manufacturer requires before any coating is scoped.
| Check | Passes when | Fails when |
|---|---|---|
| Moisture | A moisture survey (infrared, nuclear, capacitance or core cuts) shows dry insulation and deck | Saturated insulation or deck is found |
| Wet areas | Wet sections are removed and replaced with dry materials first | Wet materials would stay under the coating |
| Adhesion | Field adhesion tests meet the manufacturer's minimum | The coating will not bond to the surface |
| Drainage | Water drains off for acrylic; Gaco silicone carries no ponding exclusion | Acrylic is planned for a roof that ponds |
| Condition | Damage is limited and the surrounding roof is serviceable | Damage and wet insulation are widespread |
| Details | Flashings, drains and penetrations are secure and watertight | Details are loose or leaking |

Property managers and HOA boards need decisions they can defend. Apex Roofing's preventive maintenance program adds scheduled inspections, prioritized repairs and long-term budgeting to a coated roof.
Every coating price depends on the roof under it, so we price after the inspection and written scope. These factors move the number most.
Repairs before coating
Wet insulation, rotted decking or failed earlier repairs found during prep add labor and materials.
Materials
Coating systems and accessories are billed at supplier cost plus overhead and profit.
Crew size
Larger roofs and heavier material handling need a second technician, which raises labor.
Time on site
Labor is commonly priced in half-day or full-day blocks, and travel time counts.
Roof access
Locked hatches, occupied spaces, missing approvals or unsafe weather add time.
Distance and supplier trips
Buildings far outside the metro add mileage, and extra supplier trips add cost.

At least twice a year, preferably in spring and fall. The National Roofing Contractors Association recommends that schedule for building owners, with extra inspections after hailstorms and other severe weather. Seasonal checks catch open seams, clogged drains and coating wear while repairs are still small. Frequency can rise with roof age, rooftop traffic and warranty requirements.
Sometimes, but cold weather limits it. Henry requires the substrate to be at least 50°F before its acrylic coatings go on, and the roof must stay dry for 12 hours after. Silicone systems follow their own manufacturer limits. Coating work is scheduled for a dry window that meets the chosen system's requirements.
Yes. Hail can puncture, crack or loosen coatings and the materials beneath them, and the damage is often invisible from the ground. An inspection after a major hailstorm documents what changed while the event is recent. Repairs then use materials compatible with the existing coating system.
No. A coating maintains and extends the life of an existing roof; it does not make the roof permanent. A coated and maintained roof still reaches replacement eventually, but the timing can be planned and budgeted instead of forced by a failure. Regular inspections show when more repairs stop making technical or financial sense.
No. Apex Roofing offers a free inspection of your commercial roof. You receive photo-documented findings and a straight answer on whether coating, repair or replacement fits your building. If coating fits, the recommended work goes into a written scope before anything is scheduled, so you know exactly what you are approving.
