Commercial Roofing

Our crews have built a reputation for top notch service in the roofing industry. Anywhere you ask in the Southeast, you will hear about All-South Sub. We have won several awards and we work hard to keep our reputation solid and growing. Since 1976 when we installed Alabama’s first single-ply roof, we have put on over 70 million square feet of single-ply roofing membrane. In 1989, we added another method to our offerings: built-up roofing. If you need a commercial roof installed, we have the knowledge and experience to do it right!

The term “single-ply roofing” may be used for any of several types of compounds manufactured into flexible sheets, which use several methods of attachment to your roof. Because of the many options and combinations available, these roofs are versatile and can be adapted to most applications.

The most common roof is EPDM (Ethylene Propylene Diene Terpolymer). This material is commonly called rubber roofing. There are several other types of membranes which fall into three basic types: Thermoset, Thermoplastic, and Modified Bitumen. Each roof type has different application needs and its own set of advantages and disadvantages.

Your application will be assessed for the best product for your needs. Several factors which will be considered are cost, aesthetics (the look of your roof), wind exposure, sun or UV exposure, and building height and accessibility.

Another option to consider is a built-up roof. These systems take durability another step forward, offering several layers of fiber reinforcement sandwiched into several layers of asphalt. These roofs are incredibly strong and durable with increased water resistance. Many of these built-up roofs will still be performing perfectly after thirty or forty years and although this method is fairly new, we expect the same roofs to continue performing for another 30 after that.

The increased insulation of a built-up roof will aid in energy efficiency, with decreased heating and cooling costs. These roofs are also extremely fire resistant and meet Underwriter’s Laboratories testing and most Fire Marshall inspections. The last great qualification for these roofs is that they are extremely wind resistant.
