Raising the roof in the flat roofing game

By Jesse Sanchez. 

This durable, self-extinguishing membrane is changing expectations for roof performance and longevity. 

When it comes to commercial flat roofing, IB Roof Systems™’ PVC membranes are making noise. That’s because this roofing solution doesn’t just sit pretty under the sun; it actively resists fire, chemicals, ponding water and even time itself. Professionals in the roofing industry are paying attention, and with good reason.  

The standout features of IB PVC go far beyond the basics. One of its most practical advantages? The system doesn’t require T-patches or cut-edge sealants, saving time and cutting down on labor, a big win on any job site. As noted in IB’s brochure, “IB PVC membrane does not require seam sealants to prevent water absorption,” which speeds up installation while reducing future maintenance needs. 

Now, let’s talk longevity. IB’s proprietary acrylic finish, available exclusively on their membranes, not only improves solar reflectivity but keeps the roof cleaner, longer. That means lower energy bills and less dirt buildup, both of which contribute to the roof’s long lifespan. Their “Cool Sand” and “Cool Stone” membranes reflect up to 90% of solar radiation and meet or exceed strict California Title 24, Energy Star and Cool Roof Rating Council (CRRC) standards. 

Unlike many systems, IB PVC is designed to outlast and outperform. Ponding water? No problem. Grease and jet fuel? Still, no problem. The membrane’s resistance to chemical exposure makes it ideal for restaurants, airports and other industrial environments. 

Another exclusive? IB’s high-performance scrim doesn’t absorb water, a detail that might go unnoticed until the day it saves a roof from failure. Their brochure cites ASTM water absorption results of just 0.6%, well below the industry standard of 3%. The entire IB system is also backed by comprehensive warranties, up to 30 years in some cases, with options like the Lifetime Residential Limited Material Warranty. Contractors benefit as well, with a simplified training process thanks to easier welding and “roll and go” installation that doesn’t require cleaning seams or waiting for materials to settle. 

IB Roof Systems has over 40 years in the game and continues to lead by refining the science behind flexible, durable and sustainable PVC membranes. Whether you’re building new or restoring old, the company's membranes offer more than protection, they offer peace of mind.
