Flat Roof Repair Options
Commercial roofing offers the largest selection of roofing systems available, allowing more customization for your building. Since most commercial roofs are flat or low sloped, a waterproof and UV resistant roofing material is extremely important as these are the two most occuring damages to commercial buildings. Below are the installation and repair option available for commercial flat roof systems.
- Built Up: The original flat roof system that has been in use since the 1800s, it consists of stacking multiple layers of melted tar and asphalt shingles on top of each other to create a thick and durable flat roof at an affordable price. Built up roofs are one of the only flat roofing systems that can be walked on, but their thick layers of materials make the roof extremely heavy.
- Single Ply: Made of a stretchy, waterproof, and durable rubber membrane, these single ply roofs stretch far without tearing. Their lightweight membrane is highly reflective, lasts 20 years, and is recyclable as new membranes can be applied on top of each other.
- Modified Bitumen: Melted asphalt that is then painted onto the roof to dry into a tough seamless coating, modified bitumen is a smelly and messy process, but is highly reflective when properly installed.
- Restorative Coatings: If you are just needing flat roof repair, getting a restorative roof coating is a great way to save thousands of dollars by skipping the costly roof replacement. These powerful regenerative roof coatings are applied over your flat roof and seal together any cracks to extend the life of your roof for another 20 years.
Built Up Roofing
Built Up Roofing Installation
A rooftop deck or patio made out of a built up roofing system is a great way to utilize the extra storage space you have with a low slope roofing system. Built up roofing systems are consisting of asphalt, gravel, and fiberglass asphalt shingles to create a bulky and sturdy membrane that can cold up to 350 pounds. Because so many layers are stacked up to create the bulky roofing system, built up roofs are dense, and the installation process is a time consuming and foul smelling one. B & W Roofing and Construction can install your built up roofing system in San Antonio, TX when you phone us at (210) 849-8025 today.
What is a Built Up Roof?
As one of the cheapest flat roofing options, built up roofs provide many good benefits over their 12 year lifespan. Resistant to water, sun, fire, and chemicals, the thick tar and asphalt roof is able to be installed in any temperature. The gravel bits of the roof can potentially clog gutters, and makes it harder to identify leaks as they cover cracks, but using infrared leak detectors can easily solve this problem. Unfortunately, none of the materials used in a built up roof are recyclable, so when it comes time for a roof replacement, the entire roof has to be thrown away and replaced with a new one, increasing the already high levels of roofing landfill waste.
Modified Bitumen Roofing
Modified Bitumen Flat Roof
Modified bitumen membrane roofing is like a combination of built up roofing and single ply roofing. Asphalt and tar that are found in built up roofs are melted down into a liquid which is then coated into one thin layer onto a roof like a single ply membrane to create a modified bitumen roof. While it is very effective when it is properly installed, modified bitumen is extremely messy and dangerous to apply, making it become less popular over time. B & W Roofing and Construction has years of experience installing modified bitumen roofs in San Antonio, TX and can install your modified bitumen roof system safely and accurately when you call us at (210) 849-8025.
Benefits of a Modified Bitumen Roof
Having rubber modifiers as its base allows modified bitumen roofing to be elastic, while the melted asphalt and tar still provide durability and thickness. Modified bitumen also has insulation, a polyester membrane, base sheets, adhesive, and a protective top coating that help protect against UV and water damage and prevents wear and tear. All of these materials inside the modified bitumen membrane allow this roofing system to last 20 years before needing a recoat, and restorative roof coatings can be applied on top of these roofs to help them last another 20 years!
Single Ply Roofing
A relatively new invention for flat roofs, single ply roofing systems have taken the commercial roofing industry by storm. Lightweight, affordable, and the most reflective option for flat roofs, single ply membranes are available in multiple different base materials to perfectly match your roof, budget, and needs. Made of elastic modifiers like rubber or polymer, these membranes are completely seamless, allowing no water to get in or tears in your roof to happen! To get your singly ply roofing installed in San Antonio, TX, call the single ply roofing contractors at B & W Roofing and Construction at (210) 849-8025 today.
If your flat commercial roof sees a lot of temperature fluctuations or deals with chemicals, then PVC roofing is the only single ply roofing system that can handle these extreme fluctuations! Made of polyvinyl chloride and polyester, glass fiber, scrim, or fleece, PVC roofing rolls are elastic and strong. They are so strong in fact that they can hold up to 350 pounds, which is 150 pounds more than what other single ply membrane roofs can hold. Call B & W Roofing and Construction at (210) 849-8025 to set up an appointment for PVC roofing installation in San Antonio, TX.

This is what allows the PVC flat roof to be so withstanding and resistant to all types of weather including fire and chemicals. Even in category 3 hurricane winds will the PVC roofing sheets stay put and last for 20 years. Just like all single ply roofs, PVC roofing is energy efficient, but stands out from others as it is available in multiple colors besides the standard reflective white coating.
TPO Roofing System
TPO roofing material is made out of ethylene propylene rubber, fiberglass, talc, and rubber to provide elasticity and strength. Their polymer base helps increase their durability, making the TPO single ply roofing so strong, it can resist hail damage! Since TPO roofs are rolled or sprayed on, installation is quick, quiet, and environmentally friendly, as there is no replacement roofing that has to be discarded.

EPDM Rubber Roofing
EPDM roofs are a popular choice for commercial roofs due to their multiple installation methods. EPDM roofing membrane installation can be done by painting on the liquid coating, fully adhering the EPDM roll roofing, ballasting, mechanically attaching, or fully adhering the EPDM roofing material using specially formulated tape or fire. Available in both black and white coatings, the synthetic EPDM rubber roofing lasts 30 years when properly installed and maintained. For EPDM roofing installation in San Antonio, TX, call B & W Roofing and Construction at (210) 849-8025.
What is EPDM Roofing?
While the traditional ballast method is not used very much anymore due to how time consuming and heavy the installation makes the EPDM material, the option is still available because it is more low cost. It involves placing rock or concrete over your EPDM roofing to create a built up roofing effect. The mechanically attached or fully adhered methods are applicable to the most roofing types and provide a lightweight result as larger sheets are used to provide fewer seams.
Vulcanized Rubber Roofing
Vulcanized Rubber Roofing
Since most single ply roofs are already made of a rubber base to provide elasticity, vulcanized rubber takes it a step further by mixing the rubber with sulfur to make it even more stretchy and durable. This allows the vulcanized rubber to elongate even further while still maintaining its seamless strength. For installation of a vulcanized rubber roof in San Antonio, TX, call B & W Roofing and Construction at (210) 849-8025 today.
Benefits of Vulcanized Rubber Roofs
The advantages of using a vulcanized rubber roof compared to traditional single ply roofs are that vulcanized rubber roofs are stronger, more flexible, and more resistant to temperature and environmental changes. Other products that vulcanized rubber is used for include rainboots and tires, so this material is incredibly durable and waterproof. Rubber is very reflective, meaning that your commercial roof will be cooler and won’t get as damaged from the sun.
Probably the best benefit of a vulcanized rubber roof that really makes it stand out from single ply roofs is the amount of weight it can hold! With single ply roofs, their thin layers make it impossible for them to hold any amount of significant weight. With a vulcanized rubber roof, 200 pounds or more is nothing and won’t cause the membrane to lose its shape or rip.
