When you own a commercial business—a retail shop, dining, warehouse, manufacturing, or something else—you are responsible for the roofing, just as you would be for the residential roofing of your home. Yet, when you have loads of business dealings happening, the roof is probably the least of your worries.
And the good news is that, when the commercial roofing is functioning as it should be and protecting your business and employees from the elements, you shouldn’t have to think about it. A little preventative maintenance here and there will keep your roof around for many years.
But when a problem pops up, what do you do? Commercial roofing may not seem as straightforward as shingles, but you can demystify a roof with just a little research. And guess what? Our team at RGB Construction has already done the work for you by compiling resources and facts about commercial roofing right here.
We have everything you need to know about commercial roofing, so let’s get started.

How Do I Know When I Need A New Roof?
There are some visible signs of damage to the roof—a bubbling, puddling, interior water stains, sagging—that will clue you in right away. However, sometimes the damage is not obvious, so you will need a professional inspector to visit your facility. They will be able to assess the damages more thoroughly and tell you whether you need your commercial roofing replaced.
What Is Commercial Roofing Made From?
A majority of commercial roofs these days are made from a single-ply membrane system that is durable and energy-efficient. Some examples include TPO (Thermoplastic Olefin), PVC (Poly Vinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer). TPO is rubber and is a blend of ethylene propylene and polypropylene rubbers. EPDM is similar, but it is derived from a mix of natural gas and oil.
Other options include:
- Built-Up Roofing (BUR): A semi-flexible roofing system that uses layers of felt or another fabric between aggregate and tar. The layers increase waterproofing and durability.
- Metal: Although the cost of metal may be high, the effectiveness makes aluminum and steel popular choices. They are also environmentally friendly.
- Uncommon Materials: While gaining popularity, green roofs, or those with more eco-friendly elements involved (such as solar panels or solar shingles) are less common than single-ply membranes and BUR. However, you can implement some up-and-coming technologies into your commercial roof, if you wish.
How Long Does A Commercial Roof Last?
Even though commercial roofs tend to use similar roofing materials, it does not mean that the lifespan is always approximated. The location of the business, sun exposure, weather-related damages, and so on can affect how long your roofing lasts. For example, a restaurant that discharges oils and other residues through the ventilation may have more damage than a building without such discharge.
That said, there are various materials that last between 10-50 years. EPDM, PVC, and TPO commercial roofing are all single-ply membrane roofing types that have a lifespan between 15-30 years. Spray Polyurethane Foam lasts between 30-50 years; Metal is between 30-45 years.
Is Re-Roofing Possible? Or Do I Need To Rip Off The Current Commercial Roof?
If there is presently a single roof on your building that is in adequate condition, you may be able to save money by installing a roof over the current one, rather than replacing the entire thing.
There are two factors that affect whether a roof needs to be completely replaced:
- The building already has multiple layers of roofing. Commercial buildings cannot have more than two layers of roofing, according to law. Too many layers will add weight to the roofing system and could place stress on the building’s structure.
- The current roof is unsafe. An unstable, damaged, or water-logged roof is going to need to be torn off and replaced.
How Much Will The New Roof Cost?
Since no two buildings are exactly alike, the overall cost of installing a new commercial roof can fluctuate. As with most things, certain factors contribute to a higher price, too. This includes:
- The size of the roof
- The condition of your existing roof
- Insulation type
- Membrane type
- Roof access
- Warranty type
- Method of installation
- Present damages, such as penetrations
How Do I Choose The Right Type Of Roofing For My Commercial Facilities?
Don’t think that just because you have a commercial property that commercial roofing is a one-size-fits-all kind of thing. You could potentially choose the wrong kind of roofing and end up with nothing but problems. The best way to figure out which kind of commercial roofing is correct for your roof is to discuss options with the professional roofer. They will know which roof type will best serve your business type.
