Commercial Flat Roofing Repair & Replacement in Denver

Flat roofs have dominated the commercial and industrial space since the 1920s. Before the commercial flat roofs came into the picture, the pitched roofs were in vogue. But, flat roofs’ benefits made it as popular as it is today among commercial building owners. It is considerably much more cost-effective and easier to install as well. Moreover, the buyers have many options of flat roofing materials to choose from depending on their requirements and budget, including bitumen, EPDM, PVC, etc. 

Using commercial flat roofs allows Denver building owners to use additional square footage for various purposes, including developing a garden landscape, installing solar panels, installing air conditioners’ external units, satellite dishes, and more. The maintenance requirements of flat roofs are also comparatively low than steep slope roofs or pitched roofs.

Commercial Flat Roof Types

The roofing industry has evolved, and many new roofing materials have surfaced over the years. While there are many different types of commercial flat roofs available in the market, we at ATS Exteriors can help you choose the one that perfectly fits your requirements and budget. 

Different roofing materials have different qualities, pros and cons, and characteristics. Depending upon your business’ nature, space, building’s dimension, and other factors, we can inspect the property and guide you in the right direction to get you the best value for your money. Do not worry, as we offer free onsite inspection across Denver, Colorado. 

Here are the few common commercial flat roofing materials we deal in:

Metal Panel Roofs

Metal flat roofs are amongst the most durable roofing materials available in the market today. It offers unmatched protection and durability and can be used equivalently well for both flat and sloped roofs. With a lifespan of nearly 40 to 50 years and made of aluminum or stainless steel, one can be sure of the protection and value for money it offers.

Typically, each metal sheet has a span of four feet that is helpful during maintenance. There is a special sealant offering water-tight protection applied at the seam’s edge of every metal sheet. It not only provides better insulation but helps prevent water leakage as well. 

Built-Up Roofing (BUR)/Tar and Gravel Roofs

These variants of roofing materials are highly expensive but can last for a minimum of 50 years when properly installed. The layers of tar and other roofing materials, amounting to nearly five layers, ensure full-proof protection over the years in the harshest of weather conditions. The layers can be increased or decreased depending upon the budget and clients’ specific requirements. At ATS Exteriors, we can customize this type of roofing for our clients and add asphalt or more layers for added protection. 

Asphalt Roofs

Asphalt roofs have a life span of fifty years, but the average lifespan can come down to around ten years in high-traffic zones or when under tremendous pressure due to harsh weather conditions. When the installation or maintenance is not done properly, the wear and tear in this type of roofing material can prove expensive due to frequent roof repairs. However, asphalt roofs are much cheaper than metal roofs and BUR/Tar/Gravel roofs and are a common choice among commercial buildings such as hotels, warehouses, industrial properties, etc. 

Two-Ply Modified Bitumen

It is an expensive roofing option but needs negligible maintenance in the long-term. It offers air-tight insulation and protection due to a ceramic coating over it, which helps protect against UV rays, water leakage, and daily wear and tear. When properly installed and maintained, this roofing type can easily last for forty years or more. 

Single-Ply Synthetic Membranes (TPO, EPDM, and PVC)

There are many sub-variants of this roofing type, and it is one of the most commonly preferred roofing materials in commercial and industrial space. It is because not only are they comparatively economical, but also highly durable. The thickness of a single-ply membrane varies, and its installation process may vary as well, depending on the customer’s customization requirements. We at ATS Exteriors, Denver, Colorado, offer our clients an exhaustive range of commercial flat roof options, including –

  • Polymer-Modified Bitumen

  • Neoprene or Polychloroprene

  • EPDM or Ethylene Propylene Diene Monomer

  • PVC or Polyvinyl Chloride

  • Chlorinated Polyethylene and Chlorosulfonated Polyethylene Sheets

The lifespan of the roofing materials mentioned above ranges between thirty to fifty years. Some of the benefits of the single-ply roofing membranes are –

  • Highly Cost-Efficient

  • PVC and TPO Roofs Blocks UV Rays Efficiently

  • EPDM Roofs are eco-friendly

  • Better Insulation

Jeff and his team at ATS Exteriors did an amazing job helping me throughout the entire process of getting my roof replaced after hail damage occurred. Jeff is an honest, reputable and dedicated roofing professional. The quality of work his team did on our roof was top notch and provided me with a sense of security knowing the work was done right and that ATS is there for me for any future exterior needs I might have.

ATS exteriors, and especially Matt and Rebecca, were excellent to work with. They made sure I understood exactly what would be done and the timeline for completing the work. They were very responsive with communication and always conducted themselves like friendly professionals. They even went to bat for me to make sure my insurance company covered everything that they were supposed to. I highly recommend them and ATS Exteriors.

Rebecca and her company were top notch for two roof projects for which I hired her and her company- my duplex and my small HOA. Handling the insurance claim for a covered roof replacement does not immediately make much sense your first time through, and Rebecca guided me the whole way through all the required steps and turned a headache into a pleasure to work with her company. I recommend her and would hire her again if I ever needed a roofing company. Thanks!

We hired ATS Exteriors to replace our gutters and they did a magnificent job. They responded to my inquiry right away, came out to put together an estimate that day, and were able to get the job done within the week we hired them. We’re very happy with the finished product, and with their generous warranty policy. Truly can’t recommend these guys enough.

ATS's leadership, crew, and back-office are extremely efficient and fair. They communicated well and orchestrated all of the moving parts to accommodate our roof and related exterior updates. They easily and pro-actively took into account special considerations (kids/work/dog schedules). We HIGHLY recommend them.

Becca helped me to get another $8000 dollars in damage coverage from my insurance company because the insurance adjuster failed to notice certain items in his initial appraisal. I didn't have to talk to a single person from my insurance company. She handled every call and it went smoothly. Yay! Jeff oversaw the entire repair process from start to finish. The roof, siding and gutter replacements were completed in under a week. The crew members were courteous, efficient and very tidy. I have no reservations about recommending them for any hail damage repair.

Had Jeff and his team out to replace my old siding and update my roof. Every appointment they made with us, they showed up on time. Even after the project turned into more of a headache than originally planned (old roof with hidden surprises) they were able to work right through without trouble. I will recommend ATS to all of my friends and family in the future. Special shout out to Matt! Thanks for working extra late to get the siding finished so it wouldn't interrupt a meeting I had planned for the next day!!

Our Most Commonly Requested Commercial Roofing Questions

We often hear this same question from commercial property owners. The answer is it truly depends on several factors. First, we have to consider how extensive the leaks are in your building. We have to consider the roofing material on your building, the age of your roof, and other factors like how many times it has been repaired prior without solving the leaks. This is a case by case diagnosis. However, if a roof can be repaired, we will always strive to offer the most economical option.

We often hear this question from property managers, commercial facility managers, homeowner associations, and commercial realtors. We gladly provide free commercial roof inspections. Property managers often turn to us as their “go-to” roofers because we will provide an honest, unbiased, comprehensive report on the condition of your flat roof.

We specialize in several commercial flat roofing materials. TPO tends to be the most popular. While some buildings are better suited for an EPDM single-ply membrane, commercial metal roof, or even a PVC roof. This depends on things like the appearance you are looking for, the size of your roof, any necessary weather barrier features, and the slope of your roof. Lastly, it also depends on the budget for your roof replacement.

As a property manager, it is imperative to keep your client’s commercial roof in top shape to help prevent leaks from causing a disturbance to tenants or business operations. This is why prevention is the ideal alternative to reactionary measures when it comes to your roof. We always stress the importance of bi-annual commercial roofing inspections, so you can stay on top of problematic areas before they begin leaking. We can help you develop a plan that meets your budget, and keeps your roof in top shape with annual maintenance to avoid small problems from turning into costly leaks.

This answer entirely depends on the size of your roof, the material you are installing, the quality of the material, the slope, amongst other factors. If your roof was damaged by a hail or wind storm, then your only out of pocket cost may be your deductible. We notice quite frequently in the Denver metropolitan area that the hail storms are so severe, that they are able to damage and penetrate through flat roofs, and are often eligible for replacement through insurance to restore your building to pre-storm condition. Our roofing inspections to help determine if your roof may have been compromised are entirely free.
