Understanding Flat Roofs

Flat roofs are a popular choice for both residential and commercial buildings due to their modern aesthetic and efficient use of space. However, they demand regular maintenance and prompt repairs to prevent water infiltration and structural deterioration.

Types of Flat Roofs

There are several types of flat roofing systems, each with its own set of advantages and maintenance requirements:

  • Built-Up Roofing (BUR):

    – Composed of multiple layers of bitumen alternating with reinforcing fabrics. – Known for durability and excellent waterproofing.
  • Modified Bitumen Roofing:

    – Similar to BUR but modified with polymers for enhanced flexibility. – Resistant to temperature fluctuations and UV radiation.
  • Thermoplastic Olefin (TPO) Roofing:

    – A single-ply membrane known for energy efficiency and heat reflection. – Highly resistant to UV rays and chemical exposure.
  • EPDM Roofing:

    – Made from synthetic rubber, offering excellent weather resistance. – Flexible and durable, suitable for a variety of climates.

Common Flat Roof Problems

Flat roofs, while functional, are prone to specific issues that require timely attention:

  • Leaks and Water Infiltration:

Water pooling or seeping through can lead to significant interior damage and mold growth. If you notice water stains on ceilings or flooring, call us immediately for a complimentary inspection.

  • Blistering and Bubbles:

Usually these symptoms are the result of trapped moisture or faulty installation, weakening the roof structure over time as the substrate decays due to the excessive moisture.

  • Cracking and Splitting:

Nothing lasts forever! Exposure to harsh weather conditions can cause the roofing material to deteriorate. 

  • Punctures and Tears:

Debris, foot traffic, and poor maintenance can lead to visible damage on the roof surface. If it’s visible, it’s going to cause problems. You’ll want to call us sooner rather than later.

  • Poor Drainage:

Clogged drains or improper slope can cause water to accumulate, exacerbating other issues. If you see water standing on your flat roof, contact us immediately for an inspection.

Frequently Asked Questions about flat roof repairs

Many factors will come into play when figuring the cost of roof repairs. That’s one reason we offer a free on-site evaluation of your roof, so we can examine all of the aspects for ourselves. This allows us to give you an accurate estimate.

Of course! All of our total roof replacement work is guaranteed, including workmanship and materials following installation. Your project documents will indicate the coverage term and any limiting conditions that may apply.

Yes, we understand that roofing emergencies can occur unexpectedly. We offer prompt response times to address urgent situations and minimize damage to your property.

If leaks are isolated and less than ~25–30% of the roof is wet (confirmed by moisture scan or cores), targeted repairs or a partial recover usually make sense. If insulation is saturated across large areas, the membrane is at end-of-life, or there are multiple failed layers, replacement is the smarter (and code-compliant) move.

EPDM (rubber), TPO, PVC, modified bitumen, and built-up roofs. Typical fixes include seam welding, patching punctures, rebuilding flashing at HVAC curbs/pipes, replacing pitch pockets, clearing/scoping drains and scuppers, and correcting ponding areas.

Failed seams, cracked or pulled flashing, clogged drains, punctures from foot traffic, shrinkage at parapet walls, and standing water. We start with a leak trace (including infrared when needed), fix the source, and document with photos so you know exactly what was done.

Cost depends on membrane type, access/safety, wet insulation, and repair scope. Typical leak-stop service calls run from a simple patch to multi-area seam and flashing work; you’ll get a written estimate before we proceed. We offer same-day/next-day emergency leak response to stop active water intrusion, then schedule permanent repairs.
