I have a roof deck.

But there’s a portion that obviously isn’t covered by wood. This section can get really hot to the feet on many days of the summer (the deck was built last summer).

Does anyone have a cool idea as to what I can lay on this section so that I can easily walk on it? I know there’s the astro turf looking stuff made out of plastic.

I was just wondering whether there’s a general name for this sort of stuff or simply something else that I can easily lay down.

Below is a photo of the section of the deck that I’m talking about.

As a long time contractor I have not seen this product used on deck top roofing before but I don’t live in your area.
The most simple approach I can think of is to use some white paint the kind you use on engine blocks that comes in a rattle can. Just the difference in color should help make it cooler.

black absorbs all wavelengths of light, white reflects

Ive seen Henry brand roof paint used on black roofing. You can get it at the depot.

Ive seen a lot of those 2’x2’ rubber pads used around rooftop mechanical systems in commercial settings as a walking path to access the units.

In my dad’s community in Phoenix, many homeowners coat their patios with stuff called Kool Deck – it works pretty well from what I can tell from my visits in the summer.

Good luck,

I’d be careful what I coat it with,some coatings just made for roofing are not meant to walk on and even products that are made to walk on I would check a small area to make sure that you don’t have adhesion problems.

Look at “wood roof deck tiles”, do a google search and you will find them.

I wonder what you mean by “white paint the kind you use on engine blocks.” Maybe I should head to a local AutoZone and ask them. Why do you think this particular pain would be appropriate?


Thanks for that tip! I’ve been googling those deck tiles. Very interesting. I would never have thought of them. I need to find a place that can let me take a sample home to test how they would sit on the deck.

I also want to thank the other kind folks who have contributed to this thread. I have not ruled anything out yet. I’m very much still in the exploration stage.

The type of paint is heat resistant paint,they use it on exhaust manifolds auto zone should carry it,if you’re going to try the paint clean the surface well with naphtha or lacquer thinner, mask off a small area and apply some paint there only,give it a few days and make sure the paint adheres properly. The roof tiles may work also but I would make sure you roof cover is durable enough to take the wear and stress using those tiles will place on your roof.

The most reflective you can get will probably be leafing aluminum paint, but I don’t know about its wear characteristics, what with people walking on it.
