Repair to flat roof

Hi Doug I'm a contractor and use Karnac roof coating Home Depot sells it. You apply it with a broom or squeegee which should also be in the same isle. It comes in white black or aluminum colors. If you have any holes or seams that need that need repair you'll need to grab a 1gal can of Roof cement and mesh tape. The cement will be applied with a putty knife. Patch your holes and seams first with cement then go over that with the roof coating. Good luck if you have any questions feel free to ask. Justin

is this stuff approved for potable water systems? doesn't sound like it....

The Rooftops product is the only choice. It Is suitable for the tropics, for potable water collection, and it's longevity makes it the best deal out there.

Anyone, especially a contractor, who uses a dark colored or VOC based product in the Caribbean should be run out of town.

Carib that would make sence if I were in the Caribbean but I'm in the next best place NJ. So Doug exclude the Karnac with rooftops in my sentence. Justin

Top Coat is what most use in STT.

I would definitely put on "Peel & Stick" as an underlayment. We purchased ours at MSI as HD didn't carry it at the time. If any moisture would come through it won't ruin the wood beneath the roof.

Went to Home Depot and found their product Crossco RCS-6000 designed for rain water collection.$158.00 per 5 gallon.This looks OK, but I'll check out Roof Tops products to make sure I'm comparing apples to apples or limes to limes.Thanks for all the input about this roofing project. Seems something I can do.

Canadian roof repair, lol!

I would guess the problems flat roofs have are somewhat different in the Carribean. No snow for one thing.

Can't wait for emercaughfield's next forum contribution. Recommendations for home tanning beds perhaps?

I have always used TopCoat and always purchase from Paint Depot.
I have used on both Flat and Pitched roofs.

Be sure to plug up or disconnect the downspouts to your cistern (rooftop drains) as you do not ever want to get whatever product you may use to recoat/reseal your roof into your drinking water. That goes for anytime when you are pressure washing or cleaning your roof. You don't want to get any of that mold, mildew and other gunk into your cistern.

I usually clean roof annually or as needed, and recoat every 5-6 yrs. to proctect the roof and the drinking water that is collected from the rooftop.

I find that contractors want an allot of money to do this simple job. I got a quote for $3500.00 once, thought it was simply rediculous
and had my handyman clean and reseal the roof with the product I purchased, saved myself $2500.00 and had a lovely clean roof!.

Try to pick a couple days when no rain is expected and do not reconnect your downspouts until coating is dry or your next project may be cleaning your cistern which you shall have to hire someone to do!

PS - If you need repairs to the roof in addition to recoating then you may have to ask for other advice.
I have only had to replace the flashing in one small spot on my roof once and hired someone to do so.
That roof was original to a home that was over 45 yrs. old at the time.
It does pay to keep your rooftops clean and resealed as it enhances the longevity of your roof.
Not to mention the fact that you drink the water collected from it!
