What is a Flat Roof?

From a construction standpoint, a building will have either a sloped or flat roof, based on the needs of that structure. In general, most residential homes are sloped roofs with either hip or gable roof profiles, and most commercial buildings have flat roofs. However, not every flat-roofed building is the same, and thus the term “flat roof” is a broad term to define a specific construction method, as opposed to a specific roofing product. Because there are so many different types of buildings that have flat roofs, many products have developed over the years to suit the needs of them all. Even though an H-E-B in Castle Hills and a training building at Lackland AFB both might have flat roofs, the buildings themselves serve very different purposes and have different needs. Thus when you are choosing a flat roofing company in San Antonio it is important to choose a company who knows what kind of roof is right for your building.

Presidio Roofing was recommended to me by my insurance company and base on that I hired them to replace the roof of my house. They did an excellent job and left the yard absolutely clean! The roof inspector, Jonathan Whitaker, organized the whole project and he got the job completed in one day! He is absolutely a skilled professional.Thank you!

Nothing but great things to say about the team at Presidio Roofing. We had a roof leak around our vent hood and they pinpointed the underlying issue and resolved relatively promptly.

Great experience with Jonathan and Presidio Roofing. I had a roof that wasn't an insurance claim, just a very old, flat roof needing replacement, and Presidio had good reviews suggesting they had expertise with different types of roofs, including TPO, which I got. Sure enough, they were professional the whole way through; I got exactly the kind of roof I was looking for; and everyone I dealt with made the process as pleasant as possible. Their estimate and warranty were clear and more comprehensive and cost-effective than other estimates I got. Jonathan and the company acted with a lot of integrity throughout, so I felt I could trust them to honor the agreement.They even offer complementary maintenance inspections after the fact, which is a nice plus. Unfortunately my roof had a lot of hidden damage and took about 2x longer and more materials than expected. It's stressful to deal with such an expensive project, but less so when you feel they're not price-gouging, but trying to honor the original estimate--in fact I think they ate some of the costs to stay closer to the estimate. The work was done well and with good attention to detail and they barely disturbed the house or area at all. Jonathan was flexible with meeting times and was on time, personable, and easy to talk to about questions or concerns. He has a lot of experience and made great suggestions. He was also transparent about the process and great at knowing exactly what would work or not work and remembering every question or request I had about the roof. He spent a lot of his own time examining the old roof beforehand and I felt like he did an outstanding job communicating with the crew, the company, and myself. I highly recommend Presidio and Jonathan as professionals that take your job seriously, will stand by their work, and provide superior customer service. I hope to use them again for the gutter installation.

Presidio Roofing did my roof which was damaged after a storm. The process was super easy, well explained and fast. Everyone I came in contact with was very friendly and knowledgable. The actual crew that came to put on the roof was very mindful of my property and cleaned up after themselves. They sent me pictures of the progress and by the time I came home all was done and cleaned up. The roof looks great! I am very happy with the whole experience and highly recommend Presidio Roofing!

When we replaced our roof, there were tons of roofing companies to choose from. I researched & chose Presidio Roofing because when I mentioned their name to my insurance company they acknowledged that they were a legit & very professional company, plus easy to work with. The work was done very quick & clean. They even showed me an area of plywood which needed to be changed in order for roof to be properly installed. Fast forward a couple of years & I had a minor issue & was put in touch with Presidio and they were very understanding & resolved my issue within hours. I can't say enough good things about Presidio Roofing. I recommend them to all my family & friends. Thanks for everything.

Presidio Roofing came highly recommended from many of my friends and they were absolutely right. The Presidio team told me exactly what I needed and what I did not need. Their crew was fast and efficient. We consulted on the color and it is beautiful. In particular, since the home is older, we had some ugly air vents on the old roof that stood out for all the wrong reasons. Presidio installed modern vents that you do not even notice and are more efficient. From the inspection, to the estimate, to the drop off of materials, to the replacement, to the clean-up, to all the follow-up, Presidio Roofing is a total class company and they will make you house beautiful - and increase it’s value!! Call them - now!!

Flat Roofing Products

The different products for flat roofing systems can be broken into a few sub-categories that help define them. The primary flat roofing categories are:

Single-Ply

Single-Ply Roofing Systems are the most common type of flat roofing materials used in construction today. They are defined as large sheets of water-proof materials that do not require tar or torches for installation, have less seams that could leak than classic rolled roofing, and come with specific components and installation methods for water-proofing flat buildings to the highest degree of efficiency. Your flat roof installer in San Antonio can mechanically fasten the membrane with screws of fully adhere it with an adhesive. Most single-ply products come with manufacturer specific NDL (no dollar limit) warranties that can be registered when the products are installed correctly by a certified installer. The most common single-ply products are TPO, PVC, and EPDM and some of the most common brands are GAF, Carlisle, Firestone, and Mulehide. In general, we feel that single-ply TPO and PVC membranes are the best flat roofing material option on the market today.

Built Up Roofing (B.U.R) Systems

Built Up Roofing Systems are comprised of multiple layers of materials that when used together provide a strong unified roof that holds up well against water and severe weather. A B.U.R. starts with a base sheet, then multiple layers of ply sheets, then a cap sheet. Sometimes these systems will be called 3-ply or 4-ply systems and oftentimes when they do leak you will see additional cap sheets added to “build up” the roof even more. B.U.R. systems are the oldest flat roofing system still on the market and commonly used. The classic idea of a roofer with a kettle of tar comes from installing these roofs. GAF is an industry leader in roofing products and provides one of the best overall BUR systems on the market.

Modified Bitumen

Modified Bitumen refers to a rubberized asphalt product that has been around for 50+ years in the roofing industry. “Mod Bit” roofs come in large rolls, usually 3 feet wide, that are rolled down and adhered in one of a few different ways. They can be hot-mopped, torched down, cold-applied, or self-adhered and provide the widest range of options for installation on all different flat roofs. Modified Bitumen roofs will have a base sheet and a cap sheet and provide a cost-effective option for most building types. Both rolled roofing and B.U.R. systems can be installed utilizing a method called gravel ballasting, where a layer of gravel/rocks is laid across the top of the final membrane. This gravel weighs down the products and reduces the need to penetrate the decking with anchor screws as much.

Liquid Applied

Liquid Applied roofs are a resin that is applied using rollers or sprayers onto various types of reinforced material such as fiberglass matting, which is installed onto various roofing substrates such as metal, modified bitumen, or even certain single ply membranes. The most common coatings are Silicone and Polyurethane and have become increasingly popular in the roofing world, particularly as a cost-effective way to seal entire roofs that are leaking, without removing those whole roofs. Most single-ply roofing manufacturers also make coating products and as these products and methods of installation have continued to develop, they have quickly become one of the most common roofing products in flat roofing.

Foam

Foam roofs are a unique option that can be of great benefit to commercial and industrial flat buildings. Foam is pumped out through large barrels using a machine rig and sprayed onto existing roof membranes and substrates such as metal. A spray foam roof will then be coated with a silicone spray coating such as Gaco-Western or GAF. Spray Foam roofs provide great insulation and can be used to add insulation to an existing roof. Spray foam roofing is common on both commercial and residential flat roofs in San Antonio and across Texas.

What Flat Roofing Product is Best For You?

When you need a flat roof replacement in San Antonio one of the first questions is whether it makes sense to replace the current roof with a different product. For example, it is incredibly common for older buildings with B.U.R. or Modified Bitumen roofs to go back with a TPO or PVC roof. When it is feasible for the situation, we almost always recommend installing a TPO or PVC single ply system. These products have become the most common roofing products for new construction over the last two decades because they provide the most seamless installation, the best waterproofing capabilities, and the best NDL warranties on the market. Water does not have the ability to penetrate or degrade a TPO or PVC roof unless it is incorrectly installed, thus in most cases they are the obvious choice. But just because we recommend a certain product doesn’t take away from the fact that your roof may be best suited with a different option. That is why our trained project managers help make us the best flat roofing company in San Antonio. They will analyze and inspect your roof, document and share their findings with you, and present only the best option for your situation. Whether you are in need of a single-ply, a B.U.R, a foam, liquid applied, or modified flat roofing system, we are the best flat roofing company in San Antonio to get the job done right.
