Roof Coatings for Mobile Homes, elastormeric or asphalt based AL

[VERN in IL]

I've used the aluminum asphalt aluminum coating in the past on mobile home roofs, is the White elastomeric worth the switch? (10% increase in efficiency)

Is the elastomeric compatible with the aluminum coating that is already on the roof?(both are from kool seal)

I used elastomeric as an exterior seal on a stick built home with concrete block roof. It did reduce the heat load. It did not resolve the leak the roof had, even though I could see no gap or seam. Use a real membrane and get real results.

I have used elastomeric latex, it did very well for me.

I used it once on an asphalt-composite roof where the tar had began releasing the pebbles and the tar paper was curling. The roof shingles were basically failing. Instead of spending $20k to re-roof, I spent $100 to paint over the shingles. It sealed the pebbles back onto the shingles, and gave us another 5+ years of life from that roof. I would do it again, if I still owned that style of roof.

In fact, I would schedule to have such a roof re-painted ever 5 years, just to keep from ever having to re-shingle.

Prep is very important. Remove anything that is loose, all dirt. I even put coarse sand paper on a broom handle pad and rough up the old seams a little, wash down well and apply. The new latex worked very well for me, makes a layer that will "move" with the roof, not crack like the old coatings. White reflects the heat so it stays more stable. I apply 2 coats, a week apart, some are almost 10 years now, no leaks....James

The mobile home had several leaks when I bought this place. Two coats of elastomeric stopped the leaks. It did bubble up in one place where the water stands. I found an elastomeric that works under standing water (you put it on a dry surface) and put some on last fall. We'll see how it does.
