San Antonio roofing

Flat Roof Repair & Coatings

Porches, additions and commercial buildings across the city have flat or low-slope roofs that pond after a downpour. We repair and replace TPO and modified bitumen and coat sound membranes to reflect the sun.

The job, explained

Flat roofs are common on many homes and commercial buildings around San Antonio. Due to the region’s intense sun, seasonal storms, and occasional freezes, flat roofs can develop cracks, blisters, or pooling water that damage the roofing material. Repairing problems early helps prevent more extensive damage and costly replacements.

Applying roof coatings can protect flat roofs from UV rays, moisture, and temperature swings. These coatings can seal small leaks, improve energy efficiency, and add a reflective surface to reduce heat buildup. Regular inspections and maintenance keep flat roofs performing well year-round.

Why it matters in South Texas

San Antonio’s climate includes intense sun, seasonal hailstorms, and occasional freezes, all of which can stress flat roofing materials. Homes around the Hill Country edge often have complex roof designs that require careful repair and coating application to meet HOA or deed restrictions. Regular maintenance and protective coatings help preserve roofs against these environmental factors, extending their service life and maintaining home comfort and value.

Choices

Materials and methods we use

Elastomeric Coatings

These flexible coatings expand and contract with roof movement, providing a durable waterproof barrier that resists cracking and UV damage.

Silicone Coatings

Silicone coatings offer excellent water resistance and UV protection, ideal for areas with heavy rain or intense sun exposure.

Acrylic Coatings

Acrylic coatings are water-based and cost-effective, providing good UV protection and reflective properties for energy savings.

Polyurethane Coatings

Polyurethane coatings are highly durable and resistant to foot traffic, making them suitable for roofs with occasional maintenance access.

Step by step

Our process

  1. 1

    Inspection and Assessment

    We start by thoroughly examining your flat roof to identify damage, wear, and areas prone to leaks or ponding water.

  2. 2

    Cleaning Surface

    The roof surface is cleaned of debris, dirt, and loose materials to ensure coatings adhere properly and repairs last longer.

  3. 3

    Repairing Damage

    Damaged areas such as cracks, blisters, or punctures are patched or sealed using materials compatible with your roofing system.

  4. 4

    Applying Coatings

    A protective coating is applied evenly to seal the roof, reflect UV rays, and improve resistance to weathering and temperature extremes.

Questions

What people ask about flat roof repair & coatings

How often does a flat roof here need checking?

Flat roofs should be inspected at least twice a year and after major storms to catch damage early and maintain coatings.

Can flat roof coatings fix leaks?

Coatings can seal small leaks and prevent moisture intrusion, but larger or structural damage may require separate repairs first.

Are coatings suitable for all flat roof types?

Most flat roofs, including modified bitumen and single-ply membranes, can benefit from coatings designed for their specific materials.

How long do flat roof coatings typically last?

Coatings generally last 5 to 10 years depending on material, roof condition, and weather exposure before needing reapplication.
