Coverage & How Much You Need:
One roll covers its nominal width x length, e.g. a 10 ft. x 100 ft. roll covers roughly 1,000 sq. ft. before seams and perimeter allowance. Choose the widest roll that fits the roof to minimize seams, and add laps and edge detailing to your order.
Fit and Compatibility:
Part of the RPI Royal Edge EPDM system; use with RPI bonding adhesives, flashings and system components for a complete installation. Membrane alone is not a finished roof - adhesives, termination and flashing accessories are sold separately.
Frequently Asked Questions (FAQ):
Q: What thickness should I use?
A: .060 in. is the common choice for most low-slope roofing; .045 in. is offered where a lighter membrane is specified.
Q: How much area does one roll cover?
A: Multiply roll width by length, e.g. 20 ft. x 100 ft. is about 2,000 sq. ft.; deduct for laps, penetrations and perimeter detailing.
Q: What is included with the roll?
A: One roll of black EPDM membrane only; adhesives, flashing and system accessories are sold separately.
Q: Will it crack with building movement?
A: No, with a minimum 300 percent elongation the membrane flexes with structural movement, unlike conventional asphalt roofing.
Q: Can it be used on a green roof?
A: Yes, Royal Edge EPDM is listed by the manufacturer for green roof installations along with commercial and residential use.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick the widest roll your roof geometry allows: fewer field seams mean fewer potential leak points and faster install. For most low-slope work specify .060 in., keeping .045 in. for light-duty or specified applications. Lay the membrane and let it relax before bonding, and use only RPI system components and primers so the assembly performs as a matched system.
EPDM is slippery when wet or dusty; wear appropriate footwear and follow fall-protection requirements on low-slope roofs.
Cover your low-slope roof with RPI Royal Edge EPDM membrane in the roll size and thickness your project needs.
