Allied Roofing Company is trained and certified to install a variety of commercial roofing systems:

EPDM Roofing Systems
Durability, design versatility and installation ease are among the many reasons ethylene propylene diene monomer (EPDM) is a very popular material for both new and reroof low-slope roofing applications.  EPDM roofing systems are based on a high-performance synthetic rubber compound that provides outstanding weathering characteristics in climates worldwide.  EPDM systems can be ballasted, mechanically attached, or fully adhered.

TPO Roofing Systems
TPO membranes are a blend of polypropylene and ethylene propylene polymers and usually are reinforced with polyester.  TPO systems are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages.  TPO single-ply roofing membranes provide exceptional resistance to ultraviolet, ozone and chemical exposure and incorporate heat welded seams.  TPO systems are usually mechanically attached or fully adhered.

PVC Roofing Systems
PVC membranes are reinforced with polyester or glass-fiber mats or scrim. PVC sheets contain plasticizers and stabilizers, as well as other additives to impart flexibility and achieve other desired physical properties. Like TPO membranes, PVC membranes are also heat welded and are also usually mechanically attached or fully adhered.

Built-up Roofing Systems
Generally consist of type IV or type VI asphalt impregnated, glass fiber mat reinforced roofing felts installed in multiple layers with hot asphalt.  Aggregate surfacing is installed with a flood coat of hot asphalt on top of the plies.  Hybrid systems incorporating modified bitumen membranes with built-up roofing felts are also very popular and durable.

Modified Bitumen Systems
Modified bitumen roofing membranes are composed of reinforcing fabrics such as polyester or fiberglass that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material.  The two types of modified bitumen membranes are SBS polymer modified and APP polymer modified.   Generally, APP modifiers impart a "plasticized" quality to asphalt, and SBS modifiers impart a "rubberized" quality to asphalt.  This polymer modification and reinforcement provide exceptional elongation and fatigue resistance.   Modified bitumen membranes are installed by heat welding, hot asphalt, cold-applied adhesive or mechanical attachment.  Modified bitumen products are most durable when applied in multiple layers.  Granule surfaced cap sheets are available in different colors according to project requirements  

Metal Roofing Systems
Metal roofing system panels are generally considered architectural or structural.  Architectural metal panel roof systems are watershedding and must be used on steep slope roofs with a solid substrate, while structural metal panel systems can be used in low slope or steep slope applications.  Most structural metal panels are applied over spaced structural supports without being supported by a solid substrate.  There are many seam designs and attachment methods with both types of metal panel systems.  Warranties for metal roofing systems range from finish warranties to long term leak free warranties.
