    ...even after the leak around my skylight may be sealed.

    Here are some photos:

    So you can hopefully see some areas look to be in decent condition still, but the areas over my Arizona rooms have some large blisters, and some pitting. I was told by the neighbors that the roof was re-done about
    20 years ago or so.

    I know the proper thing to do would be to get the pros to re-roof my place, but this was quoted at about $7000.

    So I'm wondering if it would be acceptable for me to just put an elastomeric white coat over the whole roof, including all the pitting.
    The only noticeable leakage on the inside was from my skylight, which
    you can see I've tried to seal in my other thread.

    I was told that for Tucson, the Home Depot people recommend that you put a new elastomeric coating every 2 years, because of the intense heat. It seems obvious to me that the last coating on my roof was done much longer than 2 years ago.

    So what do you all think? Could I get away with just putting a
    new white coat every 2 years, and just ride this old roof out for
    another 5-10 years?

    Advice greatly appreciated in advance......Thank you.....

    All I know about this stuff is what I have read after you have posted your questions, but after looking at this, it seems to be that the problem areas are where the water dosn't drain and allowing dirt to settle. Perhaps the problem was that those areas were not cleaned good enough before last coating or maybe cleaning the dirt out from time to time would make the coating last longer.
    As far as re-coating I think the trick would be to get rid of anything loose, I've read about TSP, bleach and high pressure washer, all of which make sense at least to me.
    All of which can and likely will be corrected by people in the know. good luck.

    Yes, I've seen similar advice on Youtube, thanks for posting.

    So it sounds like since my roof isn't really leaking (except near
    the skylight that I just hopefully patched up), that it should
    be reasonable to just apply elastomeric cool white coats every
    two years, right?

    Ok, so guess what? It's coming up on two years since I started this thread, and I never applied the elastomeric coating!

    But I paid for it: The skylight I "fixed" leaked again recently, and so did two other skylights.

    So now I really have to do this.

    Question: Is it best to remove the skylight "bubble", to better access the edges of the box? It seems like it would be a bit tight to brush the elastomeric coating when the bubble is screwed into the box.

    Also: There appears to be elastomeric coating on my A/C vents, but they have gotten quite dirty. I was reading that someone people coat their A/C vents as well as the roof, and have enjoyed more efficient air conditioning, because the vents reflect the sun's energy better.

    So doesn't it make sense that I should re-coat my A/C vents again, to make them pure white and reflective again?

    Thanks in advance for any advice!
