What Is The Most Common Type Of Commercial Roof

When it comes to commercial buildings, the choice of roofing is crucial. Not only does it protect your investment, but it also plays a significant role in energy efficiency, maintenance costs, and overall aesthetics. In this blog post, we will explore the most common type of commercial roof, the options available, and the materials used.

What Are the Different Types of Commercial Roofs

Commercial roofs come in various types, each with unique features and advantages. Understanding these can help you make a more informed decision.

Flat Roofing Systems

Flat roofs are perhaps the most common type for commercial buildings. They offer ease of installation and maintenance. Typically, these roofs are made from materials like EPDM rubber, TPO, or PVC membranes. The main advantage of flat roofs is their ability to house HVAC systems and solar panels, making them energy-efficient and cost-effective in the long run.

Low-Sloped Roofs

Low-sloped roofs are similar to flat roofs but with a slight pitch to facilitate water drainage. This type is particularly popular in areas with moderate rainfall. They combine the benefits of flat and pitched roofs, offering easier equipment installation while improving water runoff. Materials commonly used include modified bitumen and built-up roofing (BUR).

Pitched Roofs

While less common for large commercial buildings, pitched roofs are often used in smaller structures and warehouses. Their steep slope helps in effective water drainage and snow shedding. These roofs are usually made from metal or shingles, providing durability and a traditional aesthetic appeal.

What Commercial Roofs Are Made Of

The material of a commercial roof is just as important as its type. Each material offers distinct benefits and is suited for different building needs.

EPDM Rubber

Ethylene Propylene Diene Monomer (EPDM) is a durable synthetic rubber roofing membrane widely used in low-slope buildings. It is known for its longevity, flexibility, and resistance to UV radiation and extreme weather conditions. EPDM roofs are relatively easy to install and maintain, making them a cost-effective option for many business owners.

TPO and PVC Membranes

Thermoplastic Olefin (TPO) and Polyvinyl Chloride (PVC) membranes are popular for commercial roofing due to their excellent energy efficiency and durability. TPO is a single-ply roofing membrane that reflects UV rays, reducing cooling costs. PVC, on the other hand, offers superior chemical resistance, making it ideal for restaurants and other establishments with grease and oil exposure.

Modified Bitumen and BUR

Modified bitumen and Built-Up Roofing (BUR) are traditional roofing materials known for their robustness. Modified bitumen is an asphalt-based material reinforced with polymers for added strength. BUR consists of multiple layers of bitumen and reinforcing fabrics, creating a durable and waterproof surface. These materials are suitable for buildings requiring heavy-duty protection against harsh weather conditions.

How to Repair a Commercial Flat Roof?

To repair a commercial flat roof, start by assessing the damage and cleaning the area. Apply a roof patch or sealant to any leaks, ensuring you follow the manufacturer’s instructions. For extensive damage, consider replacing the affected area. Regular maintenance, like clearing debris and checking for pooling water, can help extend the roof’s lifespan.

What is the Cost of a New Commercial Roof? 

The expense of installing a new commercial roof can greatly vary, typically ranging from $3.50 to $7.50 per square foot. This cost is affected by several factors, including the materials selected, the roof’s dimensions, and labor expenses. Additional elements such as insulation needs, the removal of an existing roof, and the design’s complexity can also influence the total price. For larger buildings, the average cost for a commercial roof installation may fall between $5,000 and more than $30,000.

Your Property in Good Hands

Choosing the right commercial roof involves considering building type, climate, and budget. Flat roofs, low-sloped roofs, and pitched roofs each offer unique advantages, while materials like EPDM, TPO, PVC, and modified bitumen cater to different needs. By understanding these options, business owners can make informed decisions that enhance the longevity and efficiency of their buildings.
