Roof Systems

When it comes to commercial roof systems, there are several materials to choose from. Each of them has a niche on the market and comes with certain benefits, whether it’s durability, low maintenance or reduced air pollutants. The roofing material you select will largely depend on the size, location and specific features of your building. As a Maryland roofing company, Alternative Roofing, Inc. is always available to offer our commercial clients professional advice along with professional installation.

EPDM Rubber Roofing

maryland roof systemsIn many flat and low-slope commercial roofing applications we use EPDM, which is a synthetic rubber roofing membrane. It comes in traditional black and reflective white for cool roof projects. There are two types of EPDM depending on the thicknesses: .45mil and .60mil. We can install it through adhesion, mechanical attachment or ballasting, depending on the specifics of your roof.


PVC is a flexible, thermoplastic membrane produced by using an ultraviolet-resistant polyvinyl chloride. PVC roofing is the ideal long-term solution for roofs that demand high performance at a lower life-cycle cost.

Modified Bitumen

This type of roofing is made from asphalt and a variety of modifiers and solvents that add strength and elasticity. There are several types of installation for modified bitumen roofing. In a heat application process, the seams are heated to melt the asphalt together and create a seal. There is also a cold-applied adhesive method, as well as some self-adhesive forms of this system. The different products are also referred to as APP (heat applied) or SBS (cold applied).

TPO Roofing

TPO (thermoplastic polyolefin) roofing systems combine both polypropylene (plastic) and ethylene-propylene (rubber). The result is an ideal commercial roofing system that is reliable, cost effective, energy-star rated and easy to install.

Metal Roofing

Metal roofs are common in both residential and commercial applications. Steel, aluminum, copper and galvalume are some of the metals most commonly used in commercial metal roof manufacturing. Metal roofing comes in ribbed panels designed to keep your roof cool and free of moisture. Some metal roofs qualify for the Energy Star rating and can even bring you savings in the form of tax credits or reduced insurance rates.
