Gosh. I see this post has been here for weeks and no responses.
I was hoping to get some feedback on "Cool Roofs". Is it worth the money verses the savings. If you have an existing asphalt roof, what's the best Eco-friendly upgrade?
The roof is fifteen years old and needs replacing soon.
I've been upgrading/renovating for the last few years to make my MH eco-friendly. Added straw/clay insulation all around the exterior walls, additions are paper adobe and/or sawdust clay/slip, and more.....
Now I'm finally getting around to the roof. I want to make it as earth friendly as possible. A MH roof is crappy 2 x 2 trusses, with 1/2" plywood, and asphalt shingles. My thought was to put a cool roof coating over the existing shingles. not finding a lot of info about this online. Most sites do not recommend painting a cool roof product over shingles. I talked to ANVIL (makers of roofing products) and they said it's okay, but you must clean, and then seal the shingles first, to make them less porous and for a better seal between coating and surface. Does anyone on this list have any experience with "Cool Roofs"? Is it better to use elastomeric? or a ceramic coating? I've seen some sites that say it's all a waste of time and money.
E. Henderson: Did you seal the roll roofing? What white coating product did you use? Is a fibered elastomeric better? I live in the Southern USA. Hot from May to Oct.
My building renovation design philosophy has been to use natural insulations as much as possible. I'd like to the same with the roof.
