Five Most Durable Roofing Materials for Commercial Buildings

Are you thinking about buying new roofing materials for your commercial building or replacing the existing one? Commercial roofing materials come in different forms, and each of them is used to suit the structure and owner’s pocket.

The roofing material used for a building gives it beauty and strength both on the inside and outside. The choice of roofing material often drives construction managers to become overnight experts in different building issues, including roofing.

Along the way, you will need to employ the service of a professional and experienced roofing contractor (Pittsburgh roofing companies) for an excellent roofing installation.

How to Choose the Right Roofing Materials

Choosing a roofing material for your commercial building should not be solely based on budget. Here are three important factors to also consider.

1. Geographical Location

It is wise to take into consideration the spatial environment of your commercial building. Oceanfront view, trees around the building, and a moist climate are some of the things that can affect the roof. Knowing about the environment can help to choose a kind of roof that can withstand any environmental problem.

2. Durability

You should choose a durable roofing material, even if it costs a little bit more. In the long run, it will save you the stress of spending on repairs and replacement. Naturally, aluminum and steel are the most durable roofing materials, as they can last up to 50 years.

3. Material Weight

The weight of the material is another factor to consider. Heavy materials may lead to a structural defect. Go for the roofing materials that suit the structural stability to avoid overburdening your commercial building. Using a low weight roofing material like asphalt will help to reduce the pressure on the building.

The Five Most durable Roofing Materials for Commercial Buildings

Durable Roofing Materials

When going through the different types of roofing materials for commercial buildings, you will need to discover the cost, mode of maintenance, and durability of each one.  To ease the stress, we have highlighted the five most durable roofing materials for commercial buildings.

1. Metal Roofing

Although a little bit costly, metal roofing is the ideal choice for commercial buildings. If expertly installed, metal roofs’ lifespan can be as long as 30 years or more. The only disadvantage with this form of roofing is that leaks are not prevented, which can be caused by roof edges. So, to keep the roof in good health, there should be constant inspection and maintenance.

2. Polyvinyl Chloride( PVC) Roofing

PVC comes with a lot of benefits for your building. Not only do you get to enjoy the durability and low cost of maintenance, but PVC is also able to withstand any form of climate. The roofing material also helps increase savings over its lifespan by minimizing energy costs. The cost of installing PVC is high, but the benefits of energy conservation, ease of maintenance, and durability make it an ideal choice.

3. Spray Polyurethane Foam(SPF) Roofing

SPF is a roofing material that starts as a liquid spray, instantly transforms into a foam, and immediately becomes solid. This eco-friendly roofing material is not a roof but a spray-on for the top of an existing roof with special waterproofs and an insulating system. With proper installation and maintenance, an SPF roofing material can last for up to 50years.

However, SPF’s installation period is cut down to suitable weather conditions and must be put under thorough inspection twice a year, at least.

4. Thermoplastic Polyolefin (TPO) Roofing

Thermoplastic roofing comes with a robust energy efficiency coupled with high resistance to exposure from ozone, chemicals, and UV lights. The roofing material is so popular with commercial building contractors because of its low cost. Although not as durable as metal roofing or PVC, it still offers up to 20 years’ lifespan. Other benefits such as fire-resistance, tolerance to high winds and temperature, and strong air-welded seams make TPO a common choice for commercial buildings.

5. Modified Bitumen Roofing

This roofing material usually acts as a mold for bitumen, which is then removed and installed in layers. Because they need to depend on an asphalt membrane for the roof base, modified bitumen roofing is prone to damage from bubbling or cracks. Despite its shortcomings, the roofing material remains an attractive choice for commercial buildings due to the budget-friendly installation cost and a lifespan that can exceed 15 years.


Choosing the best durable roofing material for your commercial building is still determined by the structure of the building and your budget. Metal roofing and PVC seem like an ideal choice for large expenses, while modified bitumen and TPO provide a durable but less expensive alternative for your commercial buildings.

Finally, to get the best roofing material and standard installation, there may be a need to get a professional roofing contractor’s service.
