AAR Roofing maintains applicator licenses for virtually all Major Roofing Systems. We maintain a variety of field crews that specialize in different roof applications and systems. This allows us to cater the roofing crews to your specific roof needs.
Single Ply systems
According to the Single Ply Roofing Institute (SPRI) …
The class of commercial roofing membranes commonly described as “single-ply” are flexible sheets of compounded synthetic materials that are manufactured in a factory to strict quality control requirements.
Single ply roof systems provide strength, flexibility, and long-lasting durability. The inherent advantages of pre-fabricated sheets are the consistency of the quality of the products that are manufactured, the versatility in their attachment methods, and therefore, their broader applicability.
Single ply membranes come in a variety of roll sizes and configurations. The membrane is part of the roofing system that is exposed to the elements. The costs vary greatly between types and thicknesses. Contact us to discuss the right product for your facilty.
TPO (thermoplastic polyolefin) – Normally a white sheet available from a variety of manufacturers. This sheet is an economical choice for new construction as well as re-roof projects. The seams are “hot Air” welded to ensure a solid bond. Available in a variety of thicknesses and configurations.
PVC (polyvinyl chloride) – Similar in characteristics to the TPO membrane, however this membrane is resistant to animal fats and oils. Making it an excellent choice for restaurants or other facilities where chemicals may come in contact with the roof surface. Available in a variety of thicknesses and configurations.
EPDM (ethylene propylene diene monomer)- Commonly found as a black roof membrane referred to as a “Rubber Roof”. Seams are joined by glue or a specialized seam tape. Available in a variety of thicknesses and configurations.
BUR (built up roofing) – Asphalt based roofing comprises layers of felts between layers of asphalt. This roofing is “assembled” on the roof and consists of many different variations based of the roof requirements. This is the older, standard system that most people think of when it comes to “hot tar” or asphalt roofing.
Modified bitumen membranes incorporate the high tech formulation and prefabrication advantages of single-ply with some of the traditional installation techniques used in built-up roofing. These materials are factory-fabricated layers of asphalt, “modified” using a rubber or plastic ingredient for increased flexibility, and combined with a reinforcement for added strength and stability.

APP (atactic polypropylene) – Modified BUR membrane normally applied with a torch. Used for roofing, repairs and flashings on BUR and Mod BUR roofing
SBS (styrene butadiene styrene) – Modified BUR membrane applied with hot asphalt or adhesive.
Architectural Metal Roofing – Metal panel system that is seamed together with a “standing seam” that is either snapped together, battened or hemmed. Long lasting and architecturally pleasing to the eye. Used mainly in steep sloped roofing applications.
Green Roof Systems – This roof system uses vegetation as a ballast or as part of a complex “Green” system. Specialized plants are placed onto roof systems that are installed prior to placing the plants. There are many uses and needs for vegetative systems…sometimes just for their overall appearance!
