In most cases, flat roofs start leaking because they have exceeded their functional life and are no longer waterproof. Over time, the ongoing heating and cooling of the roofing membrane expands and contracts the roofing system components and literally starts pulling the roof apart at the seams and edges.
How much does commercial flat roofing cost in Broomall, Pennsylvania and beyond?
The cost for a new flat commercial roof varies widely based on size, composition, condition, layout of the existing roof, and the number, type, size, and spacing of penetrations. Additional factors are the number, length, height, and capping of parapets, as well as the type, composition, and construction of the new roof.
How long does a new flat commercial roof last?
The average flat commercial roof will last between 7 to 15 years before it starts to leak. The best new commercial flat roofing systems will be waterproof for 20 to 30 years.
What is the best new commercial flat roofing material?
There are three primary new flat roof single-ply materials. These include TPO, EPDM & PVC. TPO is the least expensive, providing a white new flat commercial roof with welded seams.
The American Society for Testing and Materials has required TPO to be reformulated three times because of premature cracking, according to Sika Sarnafil. Black EPDM rubber is a very durable new flat commercial roof membrane. However, it depends on tape to keep water out of the seams, it’s not energy efficient, and without reinforcing, it will become unstable over time.
PVC has had the same proven formulation for over 40 years with seams that are welded to form a monolithic flat commercial roof waterproof membrane. PVC is also Energy Star ® efficient and does not support flame-spread like TPO and EPDM. It also remains weldable for modifications and repairs throughout its life.

Can I get roof coating instead of replacing my roof?
For low-slope roofs (the technical name for what most people refer to as a flat roof or a commercial roof) that have already started leaking, may not be in the best of shape, or don’t have the best drainage, the most accurate answer is “it really depends”. Some low-slope roofs will benefit from application of professional quality waterproofing roof coatings, but there are a number of important criteria that will affect whether it’s a cost-effective way to extend the life of a roof or just a Band-Aid for which the money spent would have been better put towards a new roof instead.

What is the difference between a commercial roof and a residential roof?
While commercial and residential roofing systems serve the same purpose of protecting property, they differ significantly in terms of the materials used in their construction and installation.
Commercial roofs are typically constructed from single-ply materials such as TPO, PVC, and EPDM. Residential roofs, on the other hand, are typically constructed from concrete or modified bitumen. Some residential roofs are built from tar and gravel. Because there are so many different types of commercial roofing systems to choose from, it is important to select a reputable contractor who provides extensive commercial roofing services so that you can be sure of the quality of your work.
