Bay Area Single Ply Roofing Contractor


As the name would suggest, Single Ply Roofing systems are composed of a single sheet of roofing membrane that is either fully adhered to the roof substrate with specially formulated adhesive, mechanically attached to the roof substrate with screws and plates, or held down with ballast.

The most common types of single ply roof membrane are Thermoplastic Olefin (TPO), Polyvinyl Chloride (PVC), and Ethylene Propylene Diene Terpolymer (EPDM).

Choosing which membrane is right for your building will depend on the use of the building and the roof’s proximity to certain environmental factors. We can help you decide which type of TPO, PVC, or EPDM roofing is best for your specific application.

Commonly Asked Questions About Single Ply Roofing

What is a single ply roof?

A single ply roof is a roofing system built with only one layer of material such as PVC, TPO, or EPDM. The main advantage of a single ply roof is that it is much lighter than a multi-ply roof. It also expands and contracts in extreme temperatures better than a multiply roof.

Compared to built-up roof systems, single-ply roofing is a relatively new roof membrane technology and is being used more and more in both new construction and re-roofing applications.

How long does single ply roofing last?

When installed correctly, single ply roofing can last up to 30 years. Single ply roofs come in a few different varieties, all of which are designed with very different material and installation methods. The most common types are PVC, TPO, and EPDM.

Which roof type would a single ply roof membrane be installed on?

Single ply roofing membranes are typically used for installation on low slope roof systems. When added to a tapered roof insulation system, they can be a very effective way of directing ponding water to the building’s designed drainage locations.

Compared to built-up roofing, installation of a single-ply roof system is a relatively clean process and does not come with the odor of melting asphalt like a built-up roof system. For this reason, single-ply roofing is a great choice if you need to re-roof a building while it will be occupied or if there is significant foot traffic in the area that would take offense to the smell of a built-up roof.

How do you apply single ply roofing?

Single ply roofing consists of a single layer of roofing membrane (or other material) which is applied directly over an approved, fire-retardant coverboard. One of the most important steps is to make sure the roof is dry before you start.

There are two main ways to apply single ply roofing:

  1. fully-adhered an approved adhesive
  2. mechanically attached with screws and plates

The process is different for each. The best way to apply single ply roofing is to have a qualified roofer do it for you.

What is single-ply membrane made of?

A single ply membrane is a type of roofing that is made from one piece of material that is rolled out and affixed to a roof.

Materials commonly used to make single ply membranes include PVC membrane, TPO membrane, and EPDM. These materials are often used to cover commercial and industrial buildings.

A single ply membrane is an attractive product for both the builder and the consumer. It is a durable roofing option that does not require much maintenance and is resistant to growth from algae and moss.

Is EPDM a single ply membrane?

Yes, EPDM is a single ply membrane. EPDM membrane is a type of single ply membrane made from rubber and it differs from other types of single ply membranes because of its chemical makeup. EPDM is ethylene propylene diene monomer and it is used for EPDM roofing systems.

What are the benefits of single ply roofing?

Single ply roofing is the best choice because it offers a number of benefits.

The first is that it is highly durable, making it a great choice for those who want their roof to last for decades.

Additionally, single ply roofing is more affordable than some other roofing options, which is great for those on a budget. It is also very easy to install and requires minimal maintenance.

What type of warranty is included with a single ply roof installation?

When looking at single ply roofing, there are several factors that will determine the type of warranty you receive. Since the greatest risks associated with single ply roofing are leaks due to product defects, you should seek out companies that include a minimum 20-year warranty on the material.

The best type of manufacturer’s warranty is a No Dollar Limit (NDL) warranty. When covered by these warranties, the manufacturer will agree to repair or replace portions of the roof that fail within the specified time frame.

They may even cover the interior finishes of your building, should they be damaged due to the roof’s failure.

What types of single ply roofing are there?

The main ones are: TPO, EPDM and PVC.
