SYMPTOMS

Signs your Commercial Roof needs attention

Commercial roof problems get expensive fast. Water intrusion damages inventory, equipment, and finishes. We inspect your roof, document everything, and give you a clear plan.

  1. Ponding water that stays on the roof 48 hours after rain
  2. Bubbles, blisters, or ridges in your membrane surface
  3. Visible seam separation or flashing pulling away from walls
  4. Interior leaks, water stains, or musty smell in the building
  5. Clogged or damaged roof drains backing up after heavy rain or snowmelt
  6. HVAC curb flashing cracked or deteriorated around rooftop units
  7. Dents, punctures or cuts in your membrane
  8. Your roof is past 15 years without a condition assessment

If any of these sound familiar, call (303) 808-0687. We inspect commercial roofs for free.

Flat Roof Repair, Restore or Replace: How We Decide

Most flat roof bids start by comparing membranes. We start one layer down. On a TPO or EPDM roof, the condition of the insulation and deck under the membrane usually decides whether the answer is a repair, a restoration, a re-cover or a full tear-off.

What we look at first

  • Moisture in the insulation. We core cut flat roofs, taking small samples through the roof to see whether water is trapped in the insulation, and we seal each cut.
  • The deck. Rusted steel, soft wood or sagging areas change the plan, so we check the deck wherever we can reach it.
  • Membrane age and seams. On TPO we probe the heat-welded seams. On EPDM we check seam tape, perimeter shrinkage and how weathered the rubber has become.
  • Existing layers. We count how many roofs are already on the building, because that limits the options.

How the findings point to an answer

  • Dry insulation, sound deck, trouble at a few details: usually a targeted repair.
  • Dry insulation, membrane aging across the whole field: often a silicone coating candidate, if the roof qualifies for the coating manufacturer’s warranty.
  • Wet insulation in a few defined areas: we cut out and replace the wet sections, then look at restoring or re-covering the rest.
  • Wet insulation across much of the roof, a damaged deck, or two roofs already in place: a full tear-off. Building codes generally don’t allow a re-cover over a water-soaked roof or over two existing roofs, and we won’t re-cover over a damaged deck.

When replacement is the answer

For TPO and EPDM replacements we install GenFlex and Elevate systems, and we are certified with both. Qualifying systems from either can carry a 20-year NDL manufacturer warranty, which requires a scheduled maintenance program to stay in force. Compare the membranes on our TPO roof repair and replacement page and our EPDM roof repair and replacement page.

Before the snow season

Clear drains and scuppers so meltwater has somewhere to go, and have open seams and rooftop unit flashing sealed. If the roof leaked this year, ask us to check the insulation before winter, because water trapped in insulation can keep spreading, and wet insulation adds weight to the roof.

Call 303.808.0687 and we will show you what is under your membrane before we talk options.

Commercial Roof Systems We Install

Commercial roofing systems we install and repair

Single-ply membrane with heat-welded seams for a watertight bond. Energy-efficient white surface reflects UV and reduces cooling costs. A common choice for commercial flat roofs in Colorado because of its balance of cost and performance. Available in 45, 60, and 80 mil thicknesses. Best for retail, office, and warehouse buildings where energy efficiency and budget matter.

Synthetic rubber membrane known for flexibility in extreme temperature swings. EPDM handles Colorado's freeze-thaw cycles well. Available in black and white. Seams are adhered or mechanically fastened. A cost-effective option for buildings that need reliable waterproofing without the higher price point of PVC.

Chemical-resistant single-ply membrane with hot-air-welded seams. PVC is the go-to for restaurants, commercial kitchens, and any building where grease, oil, or chemical exhaust hits the roof surface. Stronger chemical resistance than TPO and a longer track record in harsh environments. Higher material cost, but the right choice when chemical exposure is a factor.

Multi-layer asphalt membrane applied in sheets with torch, cold adhesive, or self-adhesive methods. Modified bitumen provides good puncture resistance for roofs with heavy foot traffic or rooftop equipment. Common on older Denver commercial buildings and a reliable choice for re-covering a single existing built-up roof when the insulation is dry and the deck is sound.

Standing seam and exposed fastener metal systems for commercial buildings. Metal handles snow load and UV exposure well, with low maintenance. Popular for industrial buildings, warehouses, and retail locations where aesthetics and durability both matter.

Silicone or acrylic coatings add waterproofing, UV protection, and reflectivity over an existing roof that is aging but still sound, and reduce landfill waste from tear-off material.

Blue Peaks Roofing is a Gaco-certified silicone roof coating installer, so qualifying projects can carry a Gaco manufacturer warranty of 10, 15, or 20 years. Gaco silicone is applied over many existing flat and low-slope roofs, which lets many building owners skip a full tear-off. Warranty length, required coating thickness, and eligibility are set by Gaco and depend on your roof's condition, so we start with a roof inspection and confirm which options fit your building.

Frequently Asked Questions

Commercial roofing costs depend on the roof size, system type, number of penetrations, and condition of the existing deck. TPO and EPDM single-ply systems are generally the most affordable per square foot. PVC and metal cost more and fit specific needs. We provide a free on-site inspection and detailed written estimate before any work begins.

Timeline depends on the size of the roof and the system being installed. A small retail building may take three to five days. A large warehouse or multi-unit complex can take two to four weeks. We give you a specific schedule before starting and coordinate around your business operations to minimize disruption.

Manufacturer warranties vary by system and product. We walk you through all warranty terms before you sign, and your contract spells out exactly what is covered.

TPO is a common choice for flat roofs in Colorado because of its energy efficiency and competitive cost. PVC is better for restaurants and buildings exposed to grease or chemicals. EPDM is a reliable budget option with a long track record. Metal is a good fit for sloped commercial roofs. We recommend based on your building's use, budget, and exposure.

Yes. We plan every commercial project to minimize disruption. That includes phased installation, off-hours scheduling when needed, contained staging areas and cleanup at completion. We keep you informed throughout, and your business keeps running. We communicate the schedule in advance and adjust if your operations require flexibility.

We do both. Many flat roof issues, like seam separations, flashing failures, or localized membrane damage, can be repaired without a full replacement. If the existing system is still in good condition, a targeted repair or coating restoration may be a practical alternative to replacement. We inspect and give you an honest recommendation.

Yes. We regularly work with HOA boards and property managers on multi-unit roofing projects. We provide detailed proposals for board review, attend HOA board meetings, and document roof conditions across the community.

Metal Roof vs. Shingle Roof in Colorado: How to Choose

Short answer: for most Colorado homes, an impact-resistant asphalt shingle roof is the better value, and standing seam metal is a long-term option.
