What is Commercial Roofing?

Commercial roofing systems and residential roofs primarily have the same function of protecting property. However, they are quite different when it comes to the materials used to build and install them. Commercial roofing systems are typically made up of single-ply (TPO, PVC, EPDM), concrete, modified bitumen, built-up roofing system, tar and gravel, and more. Depending on the weather conditions, residential roofs are typically made of asphalt shingles or concrete tiles.

Since more options are available for commercial roof systems as compared to residential roofs, you need to research well and choose a reliable contractor who offers extensive commercial roofing services so you can get assured results.

Types of Commercial Roofing Systems

Built-Up Roofing or BUR Membrane

Built-up roofing, also known as BUR roof, is the standard tar and gravel roof system. It consists of multiple layers or piles which enhance the durability of the system. BUR is a low-slope roof system, an ideal choice if you need a durable and cost-effective option.

Metal Roofing

Metal roofs are a popular commercial roof type. They are available in different materials, including metal tile sheets, corrugated galvanized steel, stainless steel, stone-coated steel, silicon-coated steel, copper, aggregates of aluminum, zinc, tin, and more.

Metal commercial roofing systems are durable and come with high fire-resistant ratings. They often have protective layers to prevent rusting and damage from exposure to sunlight and other environmental factors. Also, they are an attractive option and help create a more sustainable design for your property.

Modified Bitumen Roofing

Also known as mod-bit roofing, a modified bitumen commercial roofing system consists of reinforced roof fabrics and bitumen in layers. It is fastened to rooftops as two-ply systems to ensure maximum protection and stability. Modified bitumen roofs are easy to maintain and offer improved tensile strength as compared to other commercial flat roofs. It is a perfect choice of a commercial roof if you anticipate a lot of activity.

Thermoset or EPDM Roof Membrane

Thermoset roof, also known as EPDM roofing, is versatile, long-lasting, and easy to maintain as compared to other types of commercial roofs. Constructed from a single-ply rubber material, it comes with a simple installation process and has a strong resistance to ozone and ultraviolet light. EPDM roofs also have other benefits, including resistance to some solvents, acids, and alcohol, flexibility in colder temperatures, and reflective properties that can help reduce cooling expenses.

Thermoplastic or PVC & TPO Roof Membrane

Poly Vinyl Chloride (PVC) and Thermoplastic Polyolefin (TPO) roofs are perfect for second-generation applications. They are lightweight, resistant to UV rays, punctures, most chemicals and bacterial growth, and highly reflective. PVC and TPO commercial roofs are ideal for restaurants, hotels, and other businesses that release oils from the ventilation systems.

Green Roofing System

Green roofs have become popular in recent years and are a sustainable option for properties. They can improve efficiency and manage water and drainage concerns. They are also aesthetically pleasing and environmentally friendly commercial roofing material.

3 Essential Aspects of Commercial Roofing

Commercial Roof Installation

Depending on the material, pricing, labour hours, and difficulty level, the installation method of a commercial roofing system can vary greatly. It helps to hire a reliable commercial roofing contractor who can get the work done on time, within budget, and at your convenience.

Roof Inspection

A complete commercial roofing system inspection includes examining the problem areas such as roof membranes, decking, vents, flashing, gutters, downspouts, and drainage pipes. Doing so can help prevent potential roof damages, identify any problems early, and avoid costly repairs in the future.

Maintenance of Commercial Roofs

In addition to inspection, proper maintenance is critical to extending the life of a commercial roof. It includes cleaning debris, treating any leaks, tears, or water damage, repairing flashing and HVAC systems on the roof, preparing your roof for every season, and ensuring the roofing material is in excellent condition.
