Commercial Flat Roofs

The commercial roofing materials for flat roofs are measured in “squares” which is equivalent to 100 square feet. They generally cost anywhere between $250 and $350 per square, but prices can vary depending on the retailer and roof size. Warranties for flat roofs are typically good for 10 or 20 years, but with professional installation and routine maintenance, they can last up to 25 years or more. It is important to choose a reputable Indianapolis commercial general contracting company for dependable flat roof installation and repair services.

Modified Bitumen

Modified bitumen is a single-ply roll commercial roofing material infused with mineral-based exterior. This roofing material is efficient in terms of installation. There are peel-and-stick versions available on the market for those who wish to install their own new roofing, although this is strongly discouraged. There are also commercial ply roofing options that must be installed with professional equipment; a process that involves heat the adhesive as the material is rolled out.

It is a popular choice because its light-colored exterior reflects heat, which reduces energy bills. Also, it is moderately priced, right in between the cost of the other roofing materials. Since the application process is a fire hazard, it should not be installed in an occupied property. One downfall is that it’s not resistant to scuff marks and tears.

Built Up Roof (BUR)

BUR is the common hot-tar and gravel roofing seen on several types of commercial buildings throughout Indianapolis. It is assembled with alternating plies (3 or more) of waterproof materials, hot tar, and ballasted gravel. Today, these commercial roofing materials are manufactured with more advanced materials like fiberglass membranes, when before hot tar paper was the principal component. Although heavy, smelly, and messy to install, BUR can be a promising choice for some property owners and developers.

Not only is it fire-retardant, but it is also the cheapest of all the roofing materials so budgets can stay intact. But it should not be installed in a building that is occupied. This is a perfect choice for those remodeling a commercial property that is still vacant. Keep in mind that it is a big job that requires the services of a professional commercial contractor.

Rubber Membrane

Rubber roofing is an excellent choice for commercial properties in warm climates. It is effectually resistant to sunlight damage and can be installed one of three ways: glued-on, anchored with fasteners, or ballasted with stone. It is highly durable, resistant to scuffs and rips, light in weight, and water leaks are easy to patch. It is on the higher end of the price spectrum, being that it is more expensive than BUR and bitumen, but it is a wise choice for many commercial properties.

Top Solutions to Commercial Flat Roof Drainage Problems

Now that the rain is finally making an appearance again, many owners of commercial buildings with flat roof systems might be noticing some drainage issues that have developed since the last rainy season. You see, flat roofs are a common roofing system for commercial properties because they provide square footage for many major utility systems and appliances, like HVAC, solar paneling, venting, and more. Flat roofing also comes at a reasonable price, is simple to install, and can last several decades with good care.

However, flat roof systems are more vulnerable to drainage problems compared to conventional, sloped roofs. This mostly happens when they are not installed properly, or properly maintained. As a commercial building owner or proprietor, if you have noticed water drainage issues with your flat roof system recently, be sure to act fast by resolving any structural defects before winter arrives. Otherwise, you may discover a heap of damage to your roof after all the snow and ice melt away next spring.

Common Solutions for Flat Roof Drainage Problems:

Gutter Systems

Gutter systems are one of the most critical protective components of a commercial property. That is because they divert water off of a roof and away from the building. If your commercial flat roof is having drainage issues, it could be due to defective gutters, or not having a gutter system at all. Try adding a gutter system to your property, and see how well it works to protect your roof and more. Just be sure to have gutters installed by a professional and licensed commercial general contracting company in Indianapolis.


Another workable solution for poor water drainage on flat commercial roofs is scuppers. Scuppers are outlets that project water runoff away from a commercial building, very similar to how gutters work. They are positioned on the edges of a roof, so they work well to keep siding and walls dry during times of precipitation. They work better against heavy rain, but do not stand up as well against snow and ice. This means they are best suited for regions that do not experience heavy snowfall or freezing temperatures.

Internal Drains

Internal drainage systems are another great option for larger commercial buildings, especially those with roofs that tend to collect water in the center. For this reason, they are placed in intervals near the center of a roof, and retain an internal network of gutters and pipes that divert water to the exterior of a commercial building. They are commonly designed with guards or strainers that prevent leaves and twigs from obstructing any pipes.

Get a Commercial Roof Inspection Before Freezing Weather Arrives

If you do not want to be hit with an unexpected commercial roof repair, be sure to take care of any water drainage issues now while the weather still permits. Acting now will prevent further water damage, structural damage, and damage to your overall foundation. Contact an Indianapolis general contractor for expert advice and service you can trust.
