FAQs

TPO, PVC, and EPDM are all single-ply membranes, but each has unique strengths. TPO offers excellent heat-welded seams and energy efficiency, making it one of the most common choices today. PVC provides superior chemical resistance and flexibility, ideal for restaurants, industrial buildings, or high-exposure areas. EPDM is a rubber membrane known for its durability and weathering resistance, especially in cooler climates. At BEI, we’ll help you choose the right system based on building type, budget, and long-term performance needs.

It depends on your substrate, slope, and how the surface is used. For example, polyurethane and hybrid liquid systems work best for decks, balconies, and areas with movement, while silicone or acrylic coatings are great for UV-exposed flat roofs. We review your project conditions and recommend the most effective solution — not just what’s convenient to sell — because performance and longevity come first.

In many cases, yes — as long as the existing surface is dry, sound, and properly prepared. Our team often helps contractors identify whether a recover, repair, or full replacement is the smarter long-term choice. Products like Acryflex, Impethane, and Impeflex are commonly used for overlays, saving time and labor while restoring watertight protection.

Most of our systems are designed to last 20 to 25 years with proper maintenance, and many come with manufacturer-backed warranties when installed by approved contractors. At BEI, we don’t just sell products — we help you protect your warranty through maintenance programs, inspections, and technical support throughout the roof’s service life.

In most cases, yes — especially on metal, concrete, or other porous substrates. Primers like Impeprime® promote adhesion and uniform coverage, ensuring the membrane performs as designed. Our technical team can advise exactly which primer system pairs with your chosen liquid product for the best bond.

Always store products in their original sealed containers, in a cool, dry place away from direct sunlight and freezing temperatures. Liquid coatings and adhesives should be kept between 60°F and 80°F for optimal performance. On-site, avoid contamination from dust or debris, and follow all handling instructions on the TDS and SDS provided.

For most systems, apply between 50°F and 95°F, avoiding high humidity, standing moisture, or windy conditions that can affect curing. Weather windows matter — so we help contractors plan installs around forecasted conditions to achieve proper adhesion, thickness, and finish.

Yes — we offer a full line of low-VOC and VOC-free adhesives, coatings, and sealants that meet state and federal environmental regulations, including California SCAQMD Rule 1168. Our IMPER-series products combine performance with sustainability, giving you cleaner air quality and fewer job-site restrictions without sacrificing durability.

Absolutely. BEI was built on field experience — not just sales — so we provide hands-on training, product demonstrations, and job-site support to ensure installations meet spec and warranty requirements. We work directly with contractors and crews to make sure every system is applied correctly, from prep to final inspection.

Yes — our estimating team can provide coverage calculations, material takeoffs, and product recommendations based on your roof dimensions and details. Whether you’re bidding a commercial re-roof or a new deck waterproofing project, we’ll help you order the right amount of material the first time, avoiding waste and delays.
