Commercial Roofing Types in Memphis:

To give you an idea of your choices and our expertise, below we describe the 4 most popular types of flat commercial roofing systems used in Memphis, TN.

Single ply roofing systems are by far the most commonly installed systems on commercial buildings in Memphis today. They are also the most cost effective and longest lasting commercial roofs available.

Single-ply membranes can be installed fully adhered, mechanically attached or held down with ballast. Most single-ply roof systems do not receives surfacing. In many instances, a combination of attachment methods are used to secure a roof system.

For instance, an insulation may be mechanically attached to the substrate with the roof membrane fully adhered to the insulation. The most common type of single ply system we install is called TPO.

TPO is the best solution because it is, cost effective, durable, easily repairable, lightweight and has great warranties.

Built up roof membranes, referred to by the acronym BUR, have been around 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. These roof system have become rarely used since technology has advanced. But in that same way, these systems are still on most buildings today.

The reinforcing fabrics also are called roofing felts or ply sheets. Roofing felts are reinforced with either glass-fiber mats or organic mats. Felts are produced in a standard width of 36 inches and metric width of about one meter.

The bitumen typically used in BUR roof systems is asphalt, coal tar or cold-applied adhesive. The asphalt or coal tar is heated in a kettle or tanker and then applied by mop or mechanical spreader.

Asphalt is a petroleum product refined from crude oil; coal tar is derived from the distillation of coal. Cold-applied adhesives typically are solvent-based asphalts that don’t have to be heated in a kettle or tanker. It is very rare in 2015 to see a roofer fire up a kettle and apply these types of systems. Insurance companies do not like insuring contractors and building owners when these hot products are used.

We have seen many building catch fire and even people get hurt from the dangerous hot asphalt.

Surfacing’s for built up roof systems include aggregate (such as gravel, slag or mineral granules), glass-fiber or mineral surfaced cap sheets, hot asphalt mopped over the entire surface, aluminum coatings or elastomeric coatings.

Modified bitumen (MB) sheet membranes were developed in the early 1960s and have been were popular for a very long time. These roof are still installed to this day and have their purpose in the market. Polymer-modified roof membranes are composed of reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material.

MB roof system membranes are composed of multiple layers, much like BUR membranes. MB roof systems typically are installed as a two-ply system and almost always are fully adhered. We use this type of system on small residential roof and additions. They are quick, safe, and affordable.

We also install elastomeric roof coatings for certain types of roofs. They are very popular on metal roofs, BUR, and Mod-bit roofs as they begins to fail. The elastomeric coating can be applied to help the roof last longer and get some last minute usability for the customer. Most of the time, membranes can become brittle, shrink and pull away from curbs, separate seams and cause major leaks.

By being proactive and restoring the roof membrane before it is too late, allows you to avoid unnecessary and costly tear offs, reduce future maintenance costs, decrease heat transfer into buildings and therefore, increasing the ROI and life cycle cost of the roof. We highly recommend elastomeric coatings for roof repairs.
