White roof coating recommendations?

I am about to paint my (flat) roof white and looking for product recommendations. There are several levels of white roof coating at Lowe’s ranging from $31 to $140 per 5-gallon bucket. I’ve read that the cheaper ones don’t last as long and will tend to wash off. I’m leaning toward the Black Jack Ultra Roof 1000 at Lowe’s, which is $100 and is elastomeric with silicone. The $31 bucket (on sale from $62) doesn’t say elastomeric, it says just “White Roof Coating” so I fear that i’ll be back up on the roof in a couple of years recoating it….Anyone have experience with white coatings, and can tell me which are still good after several years?

If it’s an asphalt type than you could use any type of coating that specifies it will work over a BUR type roof.  Asphalt type roofs would typically have a gravel surface.  They really haven’t been too common around here since most people put on rubber roofs now.  If it’s a rubber roof, that’s a whole different ball game as most of these coatings are not designed for rubber roofs.  As I stated in a previous thread, the only company that I’m aware of that makes a diy coating for rubber roofs is Ames – you would apply one coat of super primer and then one or two coats of their Maximum stretch.  The important things to check on a white coating are the reflectivity and elasticity.  The manufacturer should be able to show you that number after a year in service as well. The better the coating, the more elastic and the more reflective over a period of time.  The better the coating, the more expensive it will typically be.     hope that helps some

Asphalt i believe. Probably around 8 years old

It is a flat roll roof, it is in good condition, no leaks. It is not now coated, just bare black

This was just touched upon in another thread last week.  What kind of roof do you have?  What kind of condition is it in?  Is there an existing coating on the roof now?
