Fire-Resistant Roofing Materials for Commercial Roofs

Fire-Resistant Roofing Materials for Commercial Roofs

June 12, 2024

If you own a commercial building, there are numerous tasks that you have to undertake to ensure that the building is a safe working space, for both business people and customers.

Fire hazards are one of the most dangerous kinds of unforeseen events, causing not only the loss of raw materials and items but also dozens of deaths. In fact, warehouse fires in the US are said to be the cause of about $155 million in damages every year.

If you wish to make your commercial space more secure, you must learn about the different kinds of fire-resistant roofing materials available in the market. So come on, let’s get started!

1. Why should you choose fire-resistant roofing?

Well, the biggest reason to go for fire-resistant roofing is to ensure that no worker or customer gets hurt if the building, warehouse, or any nearby area unfortunately catches fire for any reason whatsoever.

Certain areas in the US, such as Nevada, New Mexico, or even Colorado, are prone to wildfires, which can spread from the forest to commercial areas. And the chances of wildfires, or fire hazards in general, are greater during the dry summer months.

This is why most states or countries lay down several guidelines as to which kind of commercial roofing materials must be used in commercial buildings.

Fire-resistant roofing materials can significantly slow down the spread of fire and protect nearby buildings from further damage.

2. What fireproof roofing materials should you choose?

Remember, the materials you use for roofing in a commercial building will be different from those used in a household, like:

Metal roofing

This is a highly popular choice to protect commercial buildings from fire hazards. Not only is metal roofing very durable but it can also protect the building if any kind of flammable substance is being used inside.  

Since metal is non-combustible, it won’t get damaged during the fire and will withstand harsh environmental conditions too, thereby increasing its longevity.

With regards to maintenance, metal roofing isn’t as heavy, even if there’s a slight buildup of dirt and debris.

Asphalt shingles

Even though asphalt shingles are more commonly associated with residential rooftops, they can also be used in commercial buildings. Class-A asphalt shingles are popularly used in commercial buildings that have low slopes.  

Since this specific type of asphalt has the highest fire-resistance rating, it can effectively shield fire and cause minimal damage to the roof itself.  

These shingles are also cost-effective, even though installation charges can be a little high in some cases, and also meet strict fire safety norms.

Concrete or clay

Concrete or clay tiles are becoming widely popular because of the wide variety of interesting shapes, colors, and textures that are in the market today. Both concrete and clay are non-combustible, making them excellent choices for fireproof roofing.

They are also sustainable as they can be kept clean and attractive for a long time. Aside from offering great fire protection, concrete and clay also give the building a classic Mediterranean look, adding to the commercial area's aesthetic feel.

Thermoplastic Olefin

Thermoplastic Olefin or TPO with fire retardants are now being widely used due to their ability to efficiently utilize energy. When TPO is enhanced with fire retardants, it can provide excellent fire-resistant services.

TPO can reflect sunlight, which reduces the need to switch on air conditioners or coolers inside the building.

This can not only reduce the electricity bill generated by switching in different machines simultaneously but can also prevent sudden fire breakouts caused by faulty cooling equipment.


For flat or low-slope commercial roofs, modified bitumen is also a good option since it has multiple layers and the option to include fire retardant additives.

If your commercial space has heavy machinery installed on the roof, then modified bitumen will be a great choice because it is resistant to punctures and usual wear and tear.

It can also endure harsh weather conditions, such as extreme sunlight or rain. However, modified bitumen might not be available in a large variety of colors or options.

3. What are the other factors to consider while choosing fire-resistant roofing?

When you’re going to choose fire-resistant roofing materials, the material itself should always be your first choice. But that’s not it. There are also other factors that you must consider, such as:


The costs associated with the material and installation charges should be considered. Carefully go through the price catalogs and see if you can avail yourself of any discount options from the installation company.

Many times, the local regulatory body might lay down guidelines, asking specific commercial properties to utilize only a certain type of fireproof material.

Reputation and credibility

The company from which you buy the fireproof material, as well as the technician group that will install it on the roof, must be credible and reliable. They should be licensed and authorized professionals.


Fire-resistant roofing for your commercial space is a critical choice and must not be trusted by any local or experienced supplier. We at LA Roofing Materials understand that and offer absolute quality at competitive prices.
