A Complete Guide To Commercial Roofing

What Is A Commercial Roofing System?

Commercial roofing systems and residential roofing systems primarily have the same function of protecting property. However, they are pretty different when it comes to the materials used to build and install them.

Commercial roofing systems usually contain single-ply (TPO, PVC, or EPDM), concrete, modified bitumen shingle strip/systems built up with other materials like tar gravel depending on weather conditions.

On the other hand, residential roofs are made out of asphalt shingles for hot climates all around America, but in cold regions where snow is, standard concrete tiles are typically installed. Their durability protects more significant amounts of weight-bearing down than an average rooftop would experience since houses that use these types tend not to move much due to a foundation being laid into cement, making roof installation easier as possible.

The Types Of Commercial Roofing

Here are some of the different types of commercial roofing systems:

1. Built-Up Roofing Or BUR Membrane

The Built-Up roofing system is the standard tar and gravel roof that consists of multiple layers to enhance its durability. It’s a low-slope option for those looking for protection from rain, hail, sleet, or snow while also being cost-effective.

2. Metal Roofing

Metal roofs are the most popular commercial roof type. They come in different materials, including metal tile sheets, corrugated galvanized steel, and stainless steel. Metal roofs are durable and often come with high fire-resistant ratings and protective layers to prevent rusting or damage from exposure to sunlight or other environmental factors such as water leakage. It makes it an attractive option when designing your property’s exterior needs.

3. Modified Bitumen Roofing

A modified bitumen roofing system consists of reinforced fabric and tar in layers. It is fastened to rooftops as two-ply systems that are easy to maintain for maximum protection and stability. Modified roofs can handle a lot more activity than other commercial flat roofs because they offer improved roof strength compared with traditional methods while being easier on the budget.

4. Green Roofing System

The green roofing system is becoming increasingly common as homeowners look to go the extra mile on sustainability measures. Still, they offer many benefits that make them worth considering regardless of your location. They are environmentally friendly and aesthetically pleasing while also improving efficiency with water drainage concerns.

5. Thermoset Or EPDM Roof Membrane

Thermoset Roofing is a type of commercial roof that comes in many shapes and sizes. The material is constructed from EPDM rubber and has lots of features: It is used for simple or complicated installation processes; resistant to ozone and ultraviolet light; flexible at colder temperatures with reflective properties which help reduce cooling expenses.

6. Thermoplastic Or PVC And TPO Roof Membrane

Thermoplastic or PVC & TPO Roof Membranes are a perfect second-generation roofing solution. They’re lightweight, resistant to UV rays and punctures from most chemicals and bacteria, but not all of them. And they have one fantastic feature: a reflective surface that reflects the sun’s light into space – also known as radiant heat gain reduction! But there is an even better reason for using thermoplastics on your next commercial roof project; it will help you avoid those costly repairs when leaks happen because these roofs are incredibly durable against oil released by vents too.

7. Asphalt Roll Roofing

Asphalt roll roofing or membrane is commercial roofing commonly used for buildings that feature low-sloped roofs. The roofing is on the same materials typically found in asphalt shingles, and it’s of organic felt (or fiberglass mat) saturated with asphalt, faced off by granular stone aggregate to withstand weather elements like solid winds and heavy rainstorms.

The Importance Of Commercial Roofing

Commercial roofing is essential to the health and longevity of your establishment. Here are some of the benefits of commercial roofing:

1. Energy Efficiency

Reflective membranes and tuned ventilation help reduce heat gain and HVAC load while improving occupant comfort.

2. Reduce Liability

Proactive repairs and safe installations prevent slip hazards, ceiling failures, and inventory loss—key for property management and insurance.

3. Safety

We stage work areas, protect entrances, and follow OSHA fall-protection standards to keep tenants and crews safe.

Frequently Asked Questions

What Is The Best Commercial Roofing Type?

The best commercial roofing type are PVC roofs. They’re durable and perfect for flat surfaces like in stores where people often spend time standing below them or sitting under their shade when it’s raining outside! Metal roofs have been found suitable for buildings with steeper slopes of more than two inches, but only if they’ve also fulfilled specific qualifications. TPO is another excellent choice because it can handle many different environments without being damaged too easily by high winds or extreme weather conditions, such as hail storms that could damage other roofing types. Modified bitumen may last up to 25 years, depending on whether you maintain regular maintenance schedules (or not).

What Are Commercial Flat Roofs Made Of?

Commercial flat roofs are made of single sheets such as PVC, TPO, EPDM synthetic rubber, and more. These are of excellent quality and used in large buildings that need to withstand the elements.

What Is The Lifespan Of A Commercial Flat Roof?

The lifespan of a commercial flat roof is greatly affected by how good and how frequent the maintenance is. The life of a commercial building varies depending on which type of material is used during construction. EPDM flat roofs typically serve owners well between 30+ year spans; meanwhile, PVC roofs are resilient enough only to require replacement every 15-20 yrs if cared for properly by professionals like ourselves at Delta Roofing.
