Coating Asphalt/Fiberglass Shingles With Mastic

[hausdok]

Hi All,

I've got a client asking me about "painting" an asphalt/fiberglass composition shingle roof. This is the stuff that he's thinking about using:

This is a new one on me. In 13 years in this gig I've only seen one asphalt roof that had been painted with anything and the stuff it was coated with looked like ordinary acrylic paint to me. That roof was performing fine, by the way.

I probably wouldn't use the stuff on my own home only because I like to know more about stuff than the manufacturer tells me before I experiment with it. Can any of the brethren from Florida tell me if they've ever seen this stuff used and what, if any, negative issues accrued?

ONE TEAM - ONE FIGHT!!!

I saw it once several years ago and mistakenly wrote in my report that a 20 year old roof was "very new."

I don't know how long it lasts, but the product I saw looked great.

I don't know anything about the product but after seeing the web site I'm wondering if you get a jar of Mama Jebs cure all snake oil with every purchase...
