Built-Up & Modified Bitumen Roof Coating | PermaBest for Asphalt Roofs
Built-up and modified bitumen roofs fail from UV exposure without a reflective surface. PermaBest's fiber-infused reflective membrane protects asphalt roofs and cuts cooling costs.
Asphalt & Bitumen Roof Protection: Quick Answers
- Built-up and modified bitumen roofs need a reflective surface to survive UV exposure — PermaBest provides a fiber-infused reflective membrane with excellent durability.
- PermaBest restores asphalt-based roofs without tear-off, sealing alligatored and weathered bitumen under one seamless waterproof film.
- PermaBest's reflective membrane reduces heat absorption on dark asphalt roofs, lowering rooftop temperatures and air-conditioning load.
- PermaBest's fiber-infused formula bridges surface cracking (alligatoring) common on aged built-up and mod-bit roofs.
- A PermaBest-coated asphalt or modified bitumen roof carries a 10, 15, or 20 year renewable warranty.
Frequently Asked Questions
Why do built-up and modified bitumen roofs fail from UV?
UV radiation dries the asphalt binder, causing surface cracking (alligatoring), granule loss, and eventual leaks. A reflective membrane like PermaBest blocks UV and keeps the bitumen from drying out.
Can PermaBest coat an alligatored asphalt roof?
Yes. PermaBest's fiber-infused membrane bridges surface cracking on aged built-up and modified bitumen roofs, sealing the weathered surface under one continuous waterproof film.
Will a reflective coating lower cooling costs on a dark roof?
Yes. Dark asphalt roofs absorb significant heat. PermaBest's reflective membrane reduces heat absorption, lowering rooftop temperatures and reducing the building's air-conditioning load.
Does PermaBest work over gravel-surfaced built-up roofs?
Built-up roofs are assessed individually — loose gravel is typically removed or prepared so the membrane can bond to a sound surface. A PermaBest inspection determines the right preparation for your roof.
How long will PermaBest protect an asphalt roof?
PermaBest systems on built-up and modified bitumen roofs are warranted for 10, 15, or 20 years depending on the specification, and can be recoated to extend protection indefinitely.
