What Commercial Roofing Involves

Commercial roofing is a different animal from residential work. Your roof deck is likely steel or concrete, not wood. The slope is measured in quarter-inch per foot, not steep pitches. And the membrane — the waterproofing layer that is the heart of the system — comes in several distinct chemistries.

TPO (thermoplastic polyolefin) is the workhorse of the industry. It's a single-ply membrane with heat-welded seams, highly reflective, and cost-effective. EPDM (ethylene propylene diene monomer) is the synthetic rubber that's been around for decades, known for its flexibility in Denver's temperature swings. Modified bitumen is an asphalt-based sheet applied with a torch or self-adhered backing, often used as a cap sheet over a built-up roof. PVC single-ply is similar to TPO but with better chemical resistance — a good choice if your building has restaurant exhaust. Built-up roofing (BUR) is the classic layered system of asphalt and reinforcing felts, still specified for its durability.

We work with all of these, and with manufacturers like Carlisle SynTec, GAF EverGuard, Firestone, Johns Manville, and Versico. Each has its own specification, warranty terms, and installation details. Our job is to match the right system to your roof deck, your budget, and your expected building life.

Signs You Need Commercial Roofing

Commercial roofs fail differently than residential ones. You won't see missing shingles. Instead, watch for these symptoms:

Ponding water that remains 48 hours after a rain. This is a red flag — standing water adds weight and accelerates membrane degradation.
Membrane seam separation, where the laps between sheets pull apart. Water finds these openings quickly.
Blistering or alligatoring on the surface. Small bubbles or a cracked, scaly pattern signal the membrane is breaking down.
Flashing pull-away at the parapet or around roof penetrations. Flashing is the metal or membrane that seals the edges — when it lifts, water gets behind it.
Ballast displacement — loose gravel or pavers moved by wind, exposing the membrane underneath.
Interior staining at column lines or along exterior walls. Water travels along the roof deck before it drips, so stains may appear far from the actual leak.

Denver's climate accelerates these problems. Hailstorms with marble-sized hail can bruise a membrane, creating weak spots that fail later. Intense UV radiation at high altitude breaks down the surface of asphalt-based products. Sudden temperature swings cause expansion and contraction, stressing seams and flashing.

Our Commercial Roofing Process

We start with a roof asset survey. This is a detailed inspection of your roof's condition, including a drainage analysis and a review of the original specifications. We document everything with photos and moisture readings.

Next comes a specification review. We look at the existing system, the deck type, and the building code requirements for your area. We then write a specification for the new roof — the exact membrane, insulation thickness, and attachment method. This document is what we install to, and it's what your manufacturer warranty is based on.

The installation itself is a coordinated operation. We set up scaffold and safety harnesses for our crew. We protect your building's entrances and walkways. We coordinate with your tenants about noise and access. Then we tear off the old roof, inspect the roof deck for rot or decay, and install the new system — insulation, membrane, flashing, and any necessary coating.

Throughout the job, we keep you informed. You'll know the schedule, the milestones, and any issues we find. We don't surprise you with change orders.

Cost Considerations in Denver

Commercial roofing costs are quoted per square foot, and the range is wide. A simple TPO overlay on a clean deck might run $6–$9 per square foot. A full tear-off and replacement with a built-up roof, new insulation, and upgraded flashing could be $12–$18 per square foot. The size of your roof, the number of penetrations, and the condition of the deck all move the number.

We give you a line-item estimate so you can see exactly where the money goes. We also help you understand the return on investment — a well-insulated roof reduces your heating and cooling costs, and a reflective membrane cuts your air conditioning load in Denver's summer sun.

Warranty & Insurance

Manufacturer warranties for commercial roofs are typically NDL — No Dollar Limit — covering materials and labor for 15 to 30 years, depending on the system. To keep the warranty valid, the roof must be installed by an approved contractor, which we are. We handle the warranty enrollment paperwork for you.

If your roof has storm damage, we work with your insurance carrier. We document the damage, prepare the claim, and provide the proof of loss forms. We also help you understand your policy's claim deadline and the reserve release process.

Signs You Need Commercial Roofing

⚠

Ponding Water

Water that sits on your roof for more than 48 hours after a storm is a problem. It adds weight, accelerates membrane wear, and can lead to structural sag.

⚠

Seam Separation

If the laps between membrane sheets are pulling apart, water has a direct path in. Denver's temperature swings stress these seams, making them fail sooner.
