The title says it all. I have a 1926 house in Northern IN with the original Cement Asbestos Roof on it, I am not sure of the pitch but it is appears to be pretty standard. Previous owners have painted it, I have owned the house for 11 years so the last last coat is at least that old. It has moss growing on it, so I plan to pressure wash then bleach (capturing wash in buckets at downspouts to save landscaping) and rinse as prep. But what product should i coat with. I am considering a opaque cement deck stain with the thought that it was designed for more vertical application meaning it should take more direct sun and standing water. Any suggestions welcome.

Wow, in my 30 years in the paint biz, I have never run into this type of application. Are there any local codes that would require you to remove the asbestos roof? Also, you will have to wear a haz-mat suit and a respirator as you pressure wash, although keeping it wet keeps the fibers from free floating in the air. I am thinking a very flexible masonry coating would be the way to go because of the high temps up on the roof and I'm not so sure a stain is gonna keep the asbestos encapsulated for very long. Those are just a few thoughts........I really am stumped by this one.......hope you get some further advice from others on here that know way more than I.

No known codes requiring removal. These shingles are no different than the asbestos siding used on many houses during the period, my house also has this siding. By definition they are encapsulated unless disturbed like broken, drilled sawed etc so I am to worried about that aspect, but about durability and bond of what ever product I choose.

I've never painted a roof but I've got that asbestos siding on my house. I painted it about 15 years ago and just power washed, primed with Glidden Gripper and painted with BM Moorgard. There are a few spots that I probably didn't get prepped well enough that peeled some but for the most part it still looks good. Roof takes a bigger beating than siding though so I'm not really sure what to suggest.
