Thermoplastic polyolefin (TPO) single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages.  As demand increases for heat-reflective and energy efficient roofing systems, TPO single-ply roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure.

Polyurethane foam is sprayed directly onto the roof, where it “foams up” and solidifies before a protective coating is applied. Because of its flexibility, foam is especially useful for roofs with unusual shapes or configurations although foam is mostly applied to regular flat roofs. Foam has a number of unique advantages over other types of flat roofing systems. For one, it protects against thermal shock and it can greatly reduce your air conditioning bills.

Built-up roofing, BUR, for short, is what many people call “hot tar roofing.” A century old, time-tested roofing method, built-up roofs are made of three or four overlapping layers of asphalt felts fused together with hot asphalt.

Modified bitumen’s, like built up roofing, are made of reinforced asphalt impregnated felts. But, unlike BUR, the asphalt in the felts is modified with plastic or rubber polymers (hence the name) to improve its elasticity, durability, and overall performance. Because of the added polymers, modified bitumen is often applied in a single layer with overlapping seams. They can be “glued” to the roof with hot asphalt or an adhesive, or by using propane torches to melt the asphalt underside. Some modified bitumen requires protective surfacing materials, usually mineral granules or a liquid coating.

Single ply membranes are made of rubber, plastic or a hybrid of the two. As the name implies, single ply membranes are applied in a single layer. Installation is simple: the membrane is rolled out, the seams between sheets are heat welded, chemically welded or glued together, and the membrane is attached to the roof with fasteners (usually screws/flat plates), ballast (usually rocks), or adhesive.

A metal roof will probably be the last roof you will ever install. It offers a great-looking, life-long alternative to other common roofing materials. Over the life of your business, metal roofing will probably be the most economical choice when compared to the limited life expectancy, and re-installation and repair costs of traditional roofing materials.

Some key features of classic rib metal roofing are:
· Applies over open framing or solid substrate
· Can be applied over existing roof materials, eliminating disposal costs
· Reduces maintenance
·· Lightweight – less than 1/3 the weight of asphalt
· Can’t rot, crack, split, or break
· Fire resistant for added protection
