What Type Of Roofs Have The Longest Life Span

Time: 2021-07-06

New roofing is one of the most expensive building improvement costs a commercial property owner will face. As with most construction projects, there is a direct relationship between quality and cost. When it comes to commercial or industrial roofing in Toronto, quality matters.

Roofs made of high quality materials will provide the best longevity. In fact, it almost never makes sense to bargain when choosing materials for your commercial roof. Rather, spending a little extra on a quality commercial or industrial roof will give you more peace of mind, as the roof will not only last much longer, but will also protect your building (and the people within) much longer.

So, which roofing material is best for your commercial property in Toronto? And, which lasts the longest? We’ve outlined below some of the most common commercial roofing materials that can both properly protect your long-term investment, and provide a safe roof over your head.

1.Built-Up Roofing (BUR)

A built-up roof (BUR) is a common layered roof that is created by alternative layers of roofing felt and waterproof membrane such as fiberglass and bitumen (hot asphalt). BUR roofing is generally seen on flat roofs and can provide extreme longevity and effectiveness when installed properly.

Average Lifespan of Built Up Roofing

Built up roofs typically last anywhere from 20 to 30 years. The best way to maximize the lifespan of BUR roofs is through proper maintenance and upkeep. For example, regular inspection, repair, and by keeping debris off the roof to prevent surface degradation will ensure increased longevity.Ethylene Propylene Diene Monomer (EPDM) Roofing

2.Ethylene Propylene Diene Monomer (EPDM) is a synthetic industrial grade rubber created from a combination of ethylene propylene and diene, an unsaturated hydrocarbon alkene. EPDM roofs are flexible, yet remarkably durable, and as a result, provide a longer-than-normal lifespan.

Average Lifespan of EPDM Roofing

The rubber that comprises EPDM roofing membrane is what puts it at a higher lifespan of anywhere from 20 to 30 years. EPDM roofing can be applied in three thicknesses: 45 Mil (thousandths of inch), 60 Mil and 90 Mil. EPDM is so effective that even the 45 Mil membrane is sufficient for most small- to medium-size commercial or industrial flat roofs.

3.Polyvinyl Chloride or PVC Roofing Material

Polyvinyl Chloride (PVC) is a type of single-ply roofing membrane that is most commonly seen on flat or low-sloped structures. PVC is known for its durability and longevity because it contains cool roof pigments, UV stabilizers, and other components to extend the life of the membrane. PVC is also a cost effective option for property owners looking to lower their heating and cooling costs. Because PVC is composed of highly material, energy demand is reduced as well as monthly heating (with insulation) and cooling costs.

Average Lifespan of PVC Roofing

PVC roofing membrane is the third-most widely produced synthetic plastic polymer in the world. It’s a highly durable, long-lasting roofing material that has a lifespan of 25-30 years when properly looked after and maintained.

4.TPO or Thermoplastic Oflefin Roofing

Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber polymerized together. TPO is mostly used with flat roofs that are commonly seen on malls, shopping centers, warehouses and expansive office complexes.

Average Lifespan of TPO Roofing

While not as flexible as traditional PVC, TPO is less expensive and generally lasts 15 to 20 years, offering a cost-effective, yet very dependable alternative for most commercial or industrial flat roofs.

Toronto Businesses Rely on BUR, EPDM, PVC, TPO Roofs

Although it may be easy to choose the most inexpensive option when financing a new commercial or industrial flat roof in Toronto, taking a long-term approach will prevail. More expensive roofing material for your flat roof will provide better value over the lifetime of your property. Above all, a quality flat roof will give you a more protected building and a better long-term investment.
