Roofing Systems We Install

Allied Roofing & Sheet Metal Co. Inc., crews are professionally trained and certified to install virtually all types of commercial roofing systems available in the industry today. We assist building owners with decisions regarding the selection of brand and type of product, as well as the method of attachment.

Allied Roofing & Sheet Metal Co. Inc. thoroughly examines each roof area independently and assesses relevant factors such as type of decking, roof slope, foot traffic, insurance requirements, wind and fire resistance, building codes, etc. to provide the best roofing solution to meet your need.
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.
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.
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.
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.
Elastomeric Coating Systems
Elastomeric coatings are liquid applied, fully adhered, “rubber-like” protective membranes. They can be applied as part of a roof system during the construction stage, in retrofit or as a maintenance application. Both primer and finish coats can be spray applied to ensure quick application, consistent appearance and a durable finish. An elastomeric coating reflects up to 90% of the heat from the sun. This heat reduction saves your roof by limiting thermal shock and extends its useful life. They are so versatile, they can be used on virtually any clean, dry and mechanically sound substrate including built-up, modified bitumen, single-ply, metal, asphalt, polyurethane foam or concrete roofs (CSPE, EPDM, TPO, PVC).
