Commercial Roofing Guide

What is the definition of Commercial Roofing?

This commercial roofing guide will help explain the primary role of industrial roofing systems and residential roofing systems. The primary role of these systems are to protect the structure it covers. However, the biggest difference is the material used and installation methods used. The most common industrial roofing materials include single-ply membranes, concrete, modified bitumen, built-up roofing, tar and gravel, and others. Since there are more options for industrial roofing compared to residential roofs, building owners must do thorough research and select a reputable contractor who provides comprehensive industrial roofing services and only uses the highest quality materials in order to have guaranteed and lasting results.

Installation Of Your Commercial Roof

Commercial Roofing Guide


The installation process for a commercial roof can vary substantially depending on the material, cost, labor hours, and level of complexity. Employing a dependable commercial roofing contractor that can do the work on time, within budget, and at your leisure is advantageous.

Three Essential Commercial Roofing Elements

There are three essential elements to any commercial roofing project: proper ventilation, adequate drainage, and a quality roof covering system. Proper ventilation helps ensure that the temperature inside the building stays consistent, which can help prolong the lifespan of the roof itself. Adequate drainage prevents water from pooling on the roof and causing damage. A quality roofing system provides protection from the elements and can help improve the energy efficiency of the building.

Metal is one of the most widely used roof covering materials for sloped roof commercial buildings. There is a wide range of metal materials that can be used for roofing, including metal tiles and panels, corrugated galvanized steel, stainless steel and stone-coated steel. Commercial metal roofs are robust and have good ratings for fire and hail resistance. Most often, they include protective layers to prevent corrosion and damage from sunlight and other harmful elements. In addition, they are a very aesthetically pleasing alternative and contribute to a more sustainable property design.

Roofing Composed of Modified Bitumen

A mod-bit roof, comprised of asphalt that is combined with a rubber or plastic polymer that has been strengthened with fiberglass, creates a pliable waterproof membrane. Mod-Bit is a minimum two layer system and installed on rooftops to guarantee optimum protection. In comparison to conventional commercial roofs, mod bit roofs are easier to maintain and have greater tensile strength. It is an ideal solution for a business roof if you expect a great deal of foot traffic.

EPDM Roofing Membrane

Commercial Roofing Guide


Ethylene propylene diene terpolymer is often referred to as EPDM. This material's performance benefits includes enhanced elongation (ability to stretch), UV resistance, and the ability to withstand hail impacts. The darker colored material helps owners save on heating costs, while a lighter colored material helps owners save on cooling costs.

These systems are ideal for commercial roofing applications. These roof systems make great energy efficient "cool roofs" that provide building owners and even home owners with energy savings. These systems have a high reflectivity rating, are very lightweight, and are able to resist being degraded by the suns harmful UV rays. PVC and TPO are puncture resistant, can handle most chemicals but may be more susceptible to hail impacts. The installation process for TPO is a little more difficult because most TPO roofs require welded seams and are either mechanically fastened to the deck or is a fully adhered (glued) system. PVC and TPO roofs are also great for any establishment that utilizes a ventilation system that may expel oils, such as eating establishments.
