Elastomeric Roof Coating Question

[Eastcoast]

Yes it's that time of year again!

Can anyone recommend (or warn me away from) one of the white roof coating products sold at either one of the big box stores or a local supplier that's open to the public.

Are the ones sold at HD and Lowes crap?

Thanks

I go to Lowe's for my elastomeric coating, I never found any at Home Depot, though they may carry it now. I started buying it a few years ago, and since I only found it at Lowe's I don't bother with Home Depot anymore. I don't think there's much to worry about, I just buy what's available, usually about $80 for a 5 gallon bucket.

I use it in combination with this fiberglass fabric made for roofing. I was not able to find it locally, so I order it from Phoenix by UPS, which is cheaper. You lay down some elastomeric coating, then embed the fabric in it and add another coat.

My roof is very bad, I should have gotten a new one some years ago but can't afford it. But with this fabric and elastomeric coating I've been able to stop some severe leaks that were present when I bought the house 12 years ago and I have gotten no leaks at all this past year.

It's really a very simple thing to do on your own.

The best systems are three part systems. Primer, mesh, and top coat, usually put on with a sprayer, but several diy products are now on the market that look pretty good.

The 3 part systems are professional grade and cost is high because of the specialized installation. This is usually only cost effective on large commercial projects. If you are just trying to coat your roof to help with heat, Henrey makes a budget price one that you just roll on. None of these products are designed to add life to your roof, they are designed to reflect the sun, but as a side benefit, they do give your roof a little more life sometimes.

Thanks guys, I'm not trying to add life to my roof (it's leak free and sound), I'm just looking to reflect and equalize my 3rd floor to second floor temps a bit. I'll take a good look at the Henry stuff.

Any tips on surface prep? Assuming at the least a stiff broom and hose down 24 hours before top coating with the elastomeric.

That's it. Read the directions and you will be OK.

The reflective coating will make a major improvement for heat, but you should also confirm that your attic/roof space is air sealed and insulated.

The Energy Works program can get you a whole house energy audit for $150 which will help to pinpoint air leaks and insulation problems.

Feel free to PM me if you have any questions.

Thanks.

Oh I can guarantee that my attic/roof space is not sealed and insulated but that's going to be a job for the next owner (I hope).

How long do you plan to be in this house? A little well placed insulation shouldn't cost too much and would make you a whole lot more comfortable immediately and save you money both summer and winter.
