Commercial Roofing Made Simple

Chief Roofing has taken part in numerous commercial projects over our 30 years. These projects include churches, banks, apartment complexes, industrial buildings, and large-scale subdivision areas.

We make the process easy for our contractors and project owners by communicating what can and won’t work based on requests for proposals and specifications.

 

Apartments, Multi-Family, Banks, Subdivisions, and Industrial Projects

For small- to large-scale subdivision projects, we take our time surveying the properties totally, seeing what work is necessary and unnecessary for the HOA. We formulate a document based on an RFP, including inspection write-ups with pictures, and a complete breakdown of the entire project. In doing so, we aim to let our project owners feel confident knowing how their project is going to lay out over time from start to completion.

Our commercial installs include shingle installation, metal roofing, rubber membrane applications, and coating systems.

No matter the scope of your upcoming project, you can rely on our craftsmen for unmatched assistance. If you're interested in jumpstarting the commercial process, don't waste another moment.

Types of Commercial Roofing Systems

To give you an idea of your choices and our expertise, here are three of the most popular types of flat commercial roofing systems used in The Triangle.

 

Single Ply Roofing Systems

Single-ply roofing systems are by far the most commonly installed systems on commercial buildings in North Carolina 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 receive surfacing. In many instances, a combination of attachment methods is used to secure a roof system.

For instance, 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 (BUR)

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 bottom most ply, is mechanically fastened.

Built-up roofs generally are considered to have fully adhered if applied directly to roof decks or insulation. These roof systems 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 buildings 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 Sheet Membranes (MB)

Modified bitumen (MB) sheet membranes were developed in the early 1960s and have been popular for a very long time. These roofs 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 to. We use this type of system on small residential roofs 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 begin 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.
