Guide to Putting Decking on a Flat Roof

Flat Roof Deck Flooring Materials

If you’ve got a flat roof and and you’ve been thinking that the view from your roof is amazing. It’s a shame you can’t spend more time up there. You may just be in luck.

Many before you have asked the question, “” - and the answer is yes. That is assuming that your roof is strong enough to support support the weight.

You’ll want to start with consulting a local contractor to make sure the surface is fit for decking. Then once you have it ready for rooftop decking, visit Greatmats.com and browse its’ selection of rooftop deck tiles. Many of these tiles are even designed to accommodate rubber roofing membranes.

Flat roof deck flooring comes in many different materials which each offer their own unique benefits.

Rubber Flat Roof Deck Flooring

Rubber rooftop decking tiles offer the greatest durability and the best warranties. These floating rooftop deck flooring products are one of the heaviest options - aside from concrete. But, due to their convenient sizing, that’s rarely an issue for installation. The weight also helps keep the tiles in place during strong winds. Rubber flat roof deck flooring is also very slip resistant and at 2 inches or greater thickness offer much better cushion than concrete in case someone would happen to trip and fall while on your deck. If you want a somewhat cushioning deck floor on a flat rooftop that will hold up well to heavy furniture, rubber is your best option.

Plastic Flat Roof Deck Flooring

For smaller flat rooftop decks with lighter furniture, plastic decking tiles are a great DIY rooftop deck flooring option. The tiles offer more cushion than concrete and even rubber decking and they’re easy to install yourself by just snapping the tiles together and cutting to fit with either a power saw or a sharp utility knife. Plastic flat roof deck flooring tiles will have a perforated surface for drainage.

Rubber Foam Flat Roof Deck Flooring

Another option, if you’re willing to glue down your rooftop decking surface is rubber foam blend tiles. These offer the greatest slip resistance - even when when. They are very soft and comfortable and remain temperature stable, so you don’t have to worry about scorching bare feet in times of intense sunlight and heat. The biggest concern with rubber foam blended rooftop decking is the fact that it will be much more easily damaged by sharp objects.

You can even find WPC rooftop decking tiles that give you that nature wood look with many of the benefits of plastic.

Again Yes! - You can put decking on a flat roof - if it’s prepared properly to handle the weight.
