Different Types of Commercial Roofs and Their Pros and Cons

Different Types Of Commercial Roofs

Even though there are quite a few different types of roofs available for commercial buildings, you must consider factors like longevity, weather, and energy efficiency to decide which one is the most suitable for your requirement.

Important Factors for Selection of a Commercial Roof

The three most important factors in selecting a roof for commercial buildings are durability, cost, and energy efficiency. When installed properly and maintained well, a good-quality commercial roof system will last for up to five decades. Of course, longevity also depends to a great extent on climatic conditions. The cost of the roof is unarguably one of the most important considerations in roof selection. However, it is vital not to cut corners as it will invariably lead to a shorter lifespan and poorer performance. Energy efficiency has emerged as an important parameter in roof selection, and a well-chosen roof will lead to significant savings in energy costs over its lifetime.

Some of the Most Popular Types of Roofs for Commercial Applications and Their Pros and Cons

Metal roofs: With a typical life of 40-60 years, it is easy to see why metal roofs are popular. The advantages of a metal roof include its attractive appearance, high resistance to fire, strength, and sustainability. Its ability to reflect heat can lower the air conditioning load, according to Forbes. However, metal roofs are susceptible to corrosion, which is why many advanced types have protective coatings to limit the damage.

Built-up roofing membrane: When maintained well, built-up roofing has a life of over 200 years, according to Benchmark Roofing

. The roof comprises alternate layers of tar and gravel. It is generally inexpensive but buying a roof with many layers can jack up the cost. One of the oldest and most versatile roofing types, it is also durable and easy to repair. It is resistant to UV radiation but requires a strong understructure for good performance. However, built-up roofs do not have a long life. Also, identifying leaks that may develop with time can be difficult. This company has an excellent track record for resolving roof problems

Spray-on roofing: Polyurethane foam in liquid form is sprayed on the structure. The liquid expands into foam instantly and then hardens to form a solid layer with great noise and heat insulation properties. You can apply the foam on an existing roof and save yourself the trouble and expense of stripping the roof. However, the use of this kind of roof is limited to areas with fine weather as the foam does not tolerate water, ice, or snow.

TPO and PVC roof membranes: These industrial-grade materials are tough and can withstand various adverse conditions UV radiation, bacterial growth, chemicals, etc. They are also waterproof, heat-reflective, lightweight, puncture and fire-resistant, and can withstand high temperatures and winds. However, you must be careful to buy the best quality products as many products in the market are poorly made and cheap.


When buying a new roof for your commercial property, you need to consider whether your roof is visible, exposed to chemicals, acids, and grease, and is exposed to sun and extreme temperatures. You must buy the best possible roof within your budget after factoring in durability and potential energy savings.
