Premier Choice Exteriors (PCE) – Carries a full line commercial division. PCE’s commercial division offers services to commercial clients looking for replacement roofs, new construction roofs, or maintenance programs. Within these options PCE has the capabilities to install TPO, EPDM, Metal, Modified Bitumen, and Built-Up Roofing (BUR) systems.
TPO is one of the most popular roofing materials installed on commercial properties is a thermoplastic polyolefin, also commonly known as TPO roofing. This type of roof is comprised of an ethylene-propylene rubber that is combined with polypropylene through a polymerizing method. TPO can be attached through mechanical fastening and adhesives. All TPO is heat welded at the seams and probed to check for any deficiencies following the heat welding. There are multiple reasons to opt for this material. From durability to cost-efficiency, TPO roofing is an excellent go-to choice for commercial construction project.
EPDM stands for ethylene propylene diene terpolymer. It is a synthetic rubber roofing material that can be used on both residential and commercial structures with low slopes. The material is comprised of two main ingredients, propylene and ethylene, both of which are derived from natural gas and oil. EPDM roofing can be installed in either white or black, as well as in a variety of widths between 7.5 to 50 feet. EPDM roofing is available in three thicknesses of 45, 65, and 90 mils, and can be attached through ballasting, adhesives, or mechanical attachment. Regardless of the installation method, the seams of the rubber roofing structure are sealed with a liquid adhesive, or in some cases, a specially formulated tape will be used for sealing purposes.
Modified Bitumen Roofing
Modified Bitumen was developed in Europe during the 1960s, and it is a close relative of the old built-up roofing (BUR) system. Modified Bitumen flat roofing is a single-ply system made of asphalt bitumen, modified with polymers, and reinforced with fiberglass and/or polyester. It is assembled in a unique permutation of layers that compound to increase the roof’s effectiveness. The three ways to install Modified Bitumen are self-adhesive, cold adhesive, and heat (torch down).
Metal Roofs are typically applied to low sloping roofs of 3-12 pitch or more. Most metal roofs carry a Class A fire rating, reflect radiant heat from the sun, and can carry an increased R-Value with foam board installed under it. There are many different types of metal and profiles that can be installed over a substrate. This flexibility will typically allow a owner to achieve their desired look. The life expectancy of metal ranges from 30 – 70 years depending on what’s chosen.
Built-Up Roofing, referred to by the acronym BUR, have been in use in the U.S. for more than 100 years. These roof systems are commonly referred to as “tar and gravel” roofs. BUR systems generally are composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. The number of plies in a cross section is the number of plies on a roof: The term “four plies” denotes a four ply roof membrane construction. Sometimes, a base sheet, used as the bottommost ply, is mechanically fastened. Built up roofs generally are considered to be fully adhered if applied directly to roof decks or insulation.
