Commercial Roof Maintenance

Proper maintenance is another effective way to prolong the life of your commercial roof. Our team of roofing specialists can create a checklist to ensure your roof is properly maintained and that small issues don’t turn into big problems later on.

The Types of Commercial Roofs We Install

Spray Foam Roofing

As the name suggests, spray foam roofing is sprayed onto your roof and expands into the shape of your roof. It is an ideal solution for roofs that have complex and vulnerable areas. Spray foam roofing is also a very cost-effective way to regulate your building’s temperature. 

Modified Bitumen Roofing

Modified bitumen roofs can be installed with a torch-down or cold adhesive system. This is a great alternative when your commercial property has low VOC requirements. Let’s just say that modified bitumen is less smelly than asphalt heated to 425ºF, which is required for built-up roof installations. 

EPDM Roofing

EPDM roofs are made of a thin rubber membrane that is durable and waterproof. This is a great material for flat or low-slope roofs and is a popular choice for businesses because it is very cost-effective. It is also quite simple to install but requires professional attention, especially if installed on a larger roof. 

TPO Roofing

TPO is a single-ply membrane used on commercial roofs to protect your building from leaks. It has heat-reflective benefits and is considered a “green option” that can help your building be more energy efficient at an affordable price. 

Flat Roofs

Flat roofs are durable, functional, and versatile. That’s why they are such a popular option for commercial buildings. They are also easy to maintain so you can continue your business affairs without having to worry about your roof. We’d be happy to go over the best flat roof options for your building that will fit your business needs and budget,

    Frank did my roof inspection and explained everything to me. Frank is very knowledgeable and I recommend calling Alamo for your home project. They just finished my roof and it looks fantastic! I will be calling them for additional work. … More

    When working on older homes there are always issues and it was that for us. When Alamo was working on the facia they noticed brick issues and former facia not installed flat. They worked hard and corrected all of it. Our salesman Frank … More is beyond outstanding. A true asset to the team. He staying in close contact as any issues arrived to be sure they were not only resolved but were corrected in a most professional way. The team that installed the steep roof did an outstanding job. We waited for a few good rains before posting this review. And we are so pleased to say not only is it the most amazing roof install neat & beautifully appealing, but it does the job!! No more roof leaks :). I must also take the time to point out of Frank our Salesman services and roof inspection. We had several companies out and he was the only one that took the time to truly look at all areas of the roof. He discovered a bullet in the roof in a spot that was not leaking. He and my husband worked together so outstanding to be sure the police had it to process correctly. Never would we have thought such a thing would be in our neighborhood. The police pointed out it could have been from very far away. When the job was done Frank came by once again to be sure we were very pleased. We reviewed some of the unforseen issues and he was sure to do proper adjustments for our family. Never have we worked with such an honest and compassionate sales person. They also did an amazing job on the gutters. To say this company is good, 5 stars is not enough. They truly are such a wonderful group of folks to work with. Thank you. If our son's brother in law can not get to our siding we will be sure to have them do that as well. We have all the confidence they will do a great job on that as well. The old slogan from ghostbusters... who ya gonna call? Well for roofing issues it is Alamo Roofing... they are the best.

    I recently had a mysterious roof leak that previous companies attempted to repair, while others couldn't begin to figure out where the leak was coming from. I called Alamo, Frank came out the next morning and in 15 minutes found the … More leak, quoted me an affordable price - and made certain the leak was repaired that same day - as we were expecting another "gully washer" of storms. Frank is personable, professional and has an attention to detail that is rarely seen - anymore. Everyone I met that day brought their "A" game. They have my business - as well as pop and ice cream that I gave them. LOL Call Alamo, meet Frank - all will be well.

    I had a leaking roof from a skylight that was previously replaced by another company 13 years ago. That co, Ruel Roofing, came out to look at it and they were very unprofessional and slapped some tar around skylight and roof still leaked. … More Contacted Alamo and Frank came out, inspected roof himself, gave me a quote on high quality skylight plywood and shingles and had the job done to perfection in a very timely manner. Highly recommend Alamo Construction!

    Alamo Construction is the best! I dealt with Frank on my roofing needs. He was courteous and knowledgeable on my roof tear off. They negotiated a good price for me and sent the crew to my home and pulled permits! They were done in about … More 1 day. Yep one day! Almost 2000 sq ft in one day. Go with the best, go with Alamo!
