What is a single-ply roofing system?

A single-ply roofing system is a roof covering made of one layer of thermoplastic membrane plus a fire sheet or fireboard. In an April 2023 blog post, BYLTup, a Long Beach roofing contractor, names GAF EverGuard TPO and IB Roof Systems PVC as examples and contrasts them with built-up cap sheet and modified torch asphalt roofs. The post says these systems have been rising in popularity for their durability, ease of installation, low maintenance, warranties and ability to blend with mid-century modern design.

Why is single-ply roofing considered durable?

BYLTup says single-ply roofing is durable because its single thermoplastic layer, paired with a fire sheet or fireboard, resists UV radiation, punctures and tears while keeping a Class A fire rating. The Long Beach contractor says this extends roof life, reduces repairs and lowers ongoing maintenance costs over the long term compared with built-up cap sheet or modified torch roofs.

Is single-ply roofing a good fit for mid-century modern homes like Cliff May and Eichler designs?

BYLTup says single-ply roofing suits mid-century modern homes, such as Cliff May homes in Long Beach or Eichler homes in Orange, because their rooflines are often complicated and hard to cover with traditional materials. Large membrane sheets are welded into a watertight, monolithic finish with minimal seams. BYLTup says this streamlines installation when certified, trained installers do the work, and usually means fewer mistakes and less interruption for the owner. The post describes these homes as having open post-and-beam layouts, floor-to-ceiling windows, open beam ceilings and indoor-outdoor appeal.

How energy efficient is single-ply roofing?

BYLTup says single-ply roofing reflects UV rays instead of absorbing them, which makes it Title 24 compliant and can cut summer cooling bills by up to 30%. BYLTup presents this as a long-term saving for homeowners in hot climates such as Los Angeles and Orange County. The post does not state the conditions behind the 30% figure. BYLTup also publishes a separate Cool Roof Savings Estimates page for flat and low-slope roofs. It describes IB Roof Systems white PVC with a CRRC-rated three-year aged solar reflectance of 0.74 and emittance of 0.87, above California's Title 24 minimum of 0.63 aged reflectance. For a 1,000 sq ft low-slope roof over air-conditioned space in Long Beach, it estimates $140 to $370 per year saved versus a dark roof and $25 to $80 per year versus a code-minimum cool roof. These are estimates, not guarantees, and savings over unconditioned space such as a garage or attic can be close to zero.

What warranties come with GAF EverGuard TPO and IB Roof Systems PVC?

BYLTup states GAF EverGuard TPO comes with up to 25 years of No Dollar Limit (NDL) warranty coverage, and IB Roof Systems PVC can offer up to lifetime residential coverage limited to the material membrane. BYLTup also says these warranties are transferable to a new owner if the home is sold. Warranty terms should be verified in writing for each job.

What single-ply roofs has BYLTup published?

Yes. BYLTup has published single-ply roofs, mostly commercial, including IB Roof Systems 60 mil PVC, fully adhered, at Kress Lofts in downtown Long Beach with a 25-year IB NDL warranty, and a nearly 120,000 sq ft PVC recover at a Torrance bakery with a 20-year NDL. These are commercial examples, not mid-century homes. BYLTup's Orange County job listings also include a GAF EverGuard 60 mil TPO roof. Each project's scope is published on BYLTup's completed-jobs and commercial roofing pages.
