Flat Roof Systems We Service

We work on all major commercial flat and low-slope roofing systems, including:

  • TPO Roofing – energy-efficient, heat-welded single-ply systems

  • EPDM Roofing – durable rubber membranes ideal for large roofs

  • PVC Roofing – chemical-resistant systems for restaurants and manufacturing

  • Modified Bitumen – reinforced asphalt membranes for added durability

  • Built-Up Roofing (BUR) – multi-layer systems designed for long-term performance

If you’re not sure what type of flat roof you have, our inspection process identifies it and explains your options clearly.

  • TPO Roof

    TPO (Thermoplastic Polyolefin)

    A popular, energy-efficient membrane often used on commercial buildings. Over time, seams can separate, flashing can loosen, or punctures may occur. We heat-weld, patch, and reinforce problem areas - and when the system is past repair, we install durable new TPO roofing designed for maximum longevity.

  • EPDM (Rubber Roofing)

    EPDM (Rubber Roofing)

    EPDM systems can develop shrinkage, seam failures, and punctures from foot traffic or UV exposure. We perform precise repairs, seam resealing, and membrane patching - or complete replacement when damage is widespread.

  • Modified Bitumen

    Modified Bitumen

    A reliable asphalt-based system that can split or crack at seams. We perform targeted patching, torch-applied repairs, and full system replacements for roofs nearing the end of their service life.

  • PVC Roofing

    PVC Roofing

    PVC roofs resist chemicals and ponding, but seams and punctures can still fail over time. We repair small defects with welded patches or install new PVC systems for long-term strength.

  • Commercial metal roofs

    Commercial Metal Roofs

    Metal systems are durable but require maintenance to address rust, loose fasteners, deteriorating sealant, or panel separation. We tighten, reseal, coat, or retrofit with new metal roofing when needed.

  • Built-Up Roofing (BUR)

    Built-Up Roofing (BUR)

    “Tar and gravel” roofs can blister, crack, or develop hidden moisture issues. We repair localized damage or replace aging systems with modern, more energy-efficient solutions.

Common Flat Roof Issues We Fix

  • Leaks & Water Intrusion

    We locate the true source of leaks - often hidden beneath membranes or insulation - and stop water infiltration quickly. If leaks are widespread, we recommend the most cost-effective long-term solution.

  • Seam Failures

Pulled-apart seams are a common sign of aging or shifting membranes. We reseal, weld, and reinforce seams, or recommend replacement when failures cover large sections of the roof.

  • Punctures & Tears

Foot traffic, tools, HVAC work, and debris can puncture the roof membrane. We patch isolated damage or advise replacement if the membrane has become brittle.

  • Flashing Issues

Flashing failures around HVAC units, walls, drains, and skylights create major vulnerabilities. We reseal or rebuild flashing and evaluate whether deterioration is isolated or system-wide.

  • Ponding Water

Standing water leads to premature membrane failure, rot, mold, and deck damage. We improve drainage, reinforce weakened areas, or recommend replacement when the substrate is compromised.

  • Storm or Wind Damage

Commercial roofs take a beating during Upstate storms. We provide emergency dry-in, temporary protection, and long-term repair or replacement plans that satisfy insurance and code requirements.

Repair or Replace? We Help You Decide

Not every flat roof needs to be replaced - and not every roof can be repaired forever.

Flat Roof Repair Makes Sense When:

  • Damage is isolated (puncture, seam, flashing)

  • Insulation is still dry

  • The membrane is flexible and structurally sound

Flat Roof Replacement Is Recommended When:

  • Insulation is saturated

  • Leaks are recurring across multiple areas

  • The membrane is brittle, shrinking, or failing system-wide

  • Repairs no longer provide lasting value

Our inspections include photos and clear explanations so you can make an informed decision - no pressure, no guesswork.

What to Expect From a Commercial Flat Roof Inspection

Every flat roof inspection includes:

  • Photo documentation of problem areas

  • Identification of your roof system and condition

  • Leak source analysis

  • Repair vs replacement recommendations

  • Short-term fixes + long-term planning options

For larger facilities, we can also provide moisture detection and budget forecasting support.

Commercial Flat Roof Repair & Replacement FAQs

Q: Can a commercial flat roof be repaired instead of replaced?

A: Yes, in many cases a commercial flat roof can be repaired. If the damage is isolated - such as a puncture, seam failure, or flashing issue - and the insulation beneath the membrane is still dry, repairs can be a cost-effective solution. During our inspection, we’ll show you photos and explain whether repair, coating, or replacement makes the most sense for your roof.

Q: How do you find the source of a flat roof leak?

A: Flat roof leaks often travel before becoming visible inside the building. We trace leaks by inspecting seams, penetrations, drains, and flashing, and by checking beneath the membrane when needed. For larger or more complex roofs, we may recommend moisture detection methods to identify hidden problem areas.

Q: What causes ponding water on commercial flat roofs?

A: Ponding water is typically caused by poor drainage, structural settling, clogged drains, or compressed insulation. Standing water accelerates membrane deterioration and increases the risk of leaks. We evaluate drainage and roof structure to determine whether repairs, drainage improvements, or replacement are needed.

Q: How long does a commercial flat roof last?

A: Most commercial flat roofs last between 20 and 30 years, depending on the roofing system, installation quality, and maintenance. Regular inspections and timely repairs can significantly extend the lifespan of a flat roof and help avoid premature replacement.

Q: How long does commercial flat roof repair or replacement take?

A: Flat roof repairs are often completed in a single day, depending on the scope of work. Full replacements typically take several days, not weeks, for most commercial buildings. We provide a clear timeline before work begins and schedule projects to minimize disruption.

Q: Will flat roof work disrupt my business operations?

A: In most cases, no. We plan commercial flat roof repairs and replacements to keep businesses operational. Our crews coordinate access, staging, and work hours to reduce noise, foot traffic issues, and interruptions to tenants or employees.

Q: Is a commercial roof inspection really free?

A: Yes. We offer free commercial roof inspections that include a visual assessment, photo documentation, and clear recommendations. There’s no obligation - our goal is to give you the information you need to make the right decision for your building.
