Deck Over A Flat Roof 

Matt great thought process once again. Never imagined something so original put together so well. In a sense Seamless construction! Beautifully Amazing absolutely amazing!

I would love to see more detail on that transition at the door to the deck

Bison is THE way to go. Did the same thing (nervously) on the first house we built and it’s awesome, even for a nube-carpenter. Thanks for the vid, Matt.

On the build show!!! That deck system is awesome. Great video. Liked seeing the install details.

Always seeing and learning something new here. Just awesome thanks again for sharing the knowledge Matt.

Looks like an amazing product to use in this application!!!

WOW! What an amazing product. Matt, you've got quite the talent to show us these great products and innovative ideas! Your clients are so fortunate to have you building their homes.

Glad you tube recommended this video. Need a deck completed soon

That's a sweet cut matching the curved parapet wall. In San Francisco the FD makes people use modular decking like this when it's over a living space. I think it's brilliant, we've used it on film shoots because it is the essence of scenery: Looks great, easily usable, durable units built elsewhere, easily installed [and then taken away after the shoot]. Also the leveling legs are very like what they use for modular concert stages.

Oh man! I need this. Thanks Matt.

That's a really fascinating, cool deck. It's really appealing

Mirage makes a very similar system made for tile but you can adjust from the surface with a small t handle. Did some decks with 24x24 porcelain tiles years later still look like new

Marvelous! @4:00 Matt addressed my worry about "remove-ability of palette" in case of need to unplug scupper, drain, etc., from leaf litter or vermin infestation.

How about an in depth best practices video on yearly maintenance on these decking and siding materials. Materials, timing, conditions, what to do, what not to do.

wow great product looks very efficient and economical

Very Nice! I do work with Ipe and also I have done many projects with Ipe...and he is right, maintenance of Ipe is an every year job! Not for everybody's budget!

I'll be building one of these this summer on the flat roof I made this last summer. I will be making the deck from rift sawn white oak from our area though. Did the rubber roofing myself and have all of those videos on my channel and the videos from the Bison Pedestal deck will be coming shortly.

Looks awesome, lots of plannig .

That’s awesome!

Love your channel Matt. Please consider more content on types of roofs (decks, garden, green roof?) Any advantage to flat roofs with usable space?

beautiful work!

I was looking to do a floating deck for my flat roof. I'll give this a try.

Thanks for saying it will go gray. Love the transparency with the product.

This looked very interesting for a low profile deck I wanted to do for the 26 foot opening I made for a bi fold system. I needed something low profile enough to make an even transition from inside laminate flooring to the opening of the bi fold doors to the deck outside. I was thinking about making a concrete slab, and purchasing those feet and deck wood. BUT going to the website, it’s one of those where you have to request the price. I hate that. They’re just feet and square panels of wood. I don’t understand why you don’t just put the price up on the website? Lost my business. Too bad seemed like a good way to go...

Great video - great system.

Videos are great, but I'd love to see this project up close!

these stand offs are great. anyone or have you Matt ever done a Living Roof with a floating deck like this?

Awesome deck

thanks, great video and nice products

thanks for the video. lots of great information

Very interesting. Thanks for the Vid!! Good job

They make very attractive structural tiles that span the distance between the plastic support piers. They will last forever without maintenance in the harshest climates. Looking at them at building shows they appear to get their strength from an integrated fiberglass grid mesh either within the tile or adhered to the lower surface.

Epay? Looks good nice easy system . Those adjustable feet have been around awhile we used them under floating tiles over a tanked roof cam up mint!

"Couple days" XD XD XD !! Other than that ^^ It's a great looking deck & very professional looking install

To fix the issue he mentioned about rotting pressure treated sleepers: Use PVC decking material instead of wood, that way the part that is (potentially) sitting in water isn't going to rot.

We have something similar in Europe. They will take some phenomenal maximum loading (500kg each). I used them to re-support a large timber shed that had shifted in level one end.

I need one of those shirts !!

Excellent!

Awesome video. The Ipe looks incredible. That deck must cost a fortune. Can you give a quick price breakdown for installing a deck like that?

This looks like a great solution.. I imagine its very expensive considering I haven't found any prices on their website.

Hey Matt! How was the parapet siding finished over the membrane? Also, how was the roof's ventilation handled? I have a similar rooftop terrace over my garage but I'm struggling to get decent finish on the edges of the parapet without having to put an aluminum fascia that will cover the edges of my tiles (and the top of my brick parapet). Thanks for the input! Btw, good job on this roof deck!

Love your video. We currently are remodeling and would like to install the wooden pie deck. Could I install with 2 inch depth on my flat roof patio?

great informative video as always. What's the S.F cost for installation of the bison's?

I have this in an upcoming project, and thing special you would recommend for the TPO or the iso under it?

I know this is an old video but hope you'll be able to answer my question. I am considering this system to build a deck on a flat roof in South Florida. My concern is with wind speeds during the hurricane season. How do you ensure the entire structure will be stable and still with high wind conditions without perforating the surface where it will sit?

An excellent north American wood for decking is black locust. In the U.S. the locust borer makes commercial growing of black locus generally unprofitable. The wood is very rot resistant and tough - it can bend nails. Some is harvested from West Virginia. Its widely grown in Europe because the locust borer larvae were never brought to Europe. It also makes lovely furniture. If the locust borer can be controlled it would become one of the most popular woods in the U.S. because the trees grow rapidly, its actually a legume so it grows on poor soils.

Well done field guys straight ass line

What do you do about leaves and debris that gets under the deck? Regular removal and cleaning?

Used as the deck in SV Seeker!

I wanna see how your Carpenters scribed up to that curved wall and what saw they used to cut it. Looks flawless.

When you build stuff like this that covers a drain or whatever. Do you take a picture from above before the decking is installed? Then with the decking installed with markers to mark out where the fasteners, screws, are? If I was the home owner, I would love to have these pictures so I would know where the drains are and how to access those drains. Whether I would personally clean out the drains or hire someone else. Having this information would be helpful on so many fronts.

Because all the 2'x4' component decks look to be mechanically fastened to the standoffs there is no worry about the standoffs moving over time since they're not fastened to the roof. What that means is you basically have one macro system that's linked at the corners. Because the decking butts up flush to the the inside walls of the roof there doesn't exist the room for the entire system to shift. It's basically a friction-fit flooring system. Neato.

@matt - what’s your view point on Trex instead of Ipe? Seems like a better product for durability, but have you seen different results in the humid SE?

I'm putting a composite deck on a flay asphalt roof and was curious if Bison makes a stand off for my application.

Great perimeter seem. What's the wind rating?

I’ve seen builders using a hybrid of Sleepers for framing a desk on the stand-offs so the Entire deck is still free-floating but you’re able to use a wider variety of other decking materials. I’m interested in a bamboo composite decking that isn’t available in longer-length deck panels/tiles. Do you think the decking panels on the standoffs or the sleepers on the stand-offs is a better way of installing a free-floating deck? Or similar are they similar?

Hey Matt, builder from FL... Still hoping you can do a series on hurricane reinforcements?!

Nice product and superb installation. I let my ipe grey naturally. It is too much work to reseal it every year.

Other than extra damage protection and fire safety for the actual roof, are there functional benefits to doing this? I know aesthetically it looks great, but if it would be used only by the residents below (and no grilling or fire hazards), is it necessary?

This looks great. Can this system support a hot tub

Really curious if you think it would be possible to create your own platforms to sit on the Bison feet. I'm really wanting to do a herringbone design and they don't offer that.

Can you install a rail system directly onto this system? If so, how is it attached and supported?

Would the drains be sufficient to handle heavy rainfall? What would happen with overflow? How about clogging, when drains get partially clogged? It would be a perfect moscito breeding ground when you get standing water under the deck.

With this, you could run pool pvc pipes underneath for a rooftop pool

Would you recommend this for a penthouse with a lot of roof space around it. We are told that we can build a deck since it is part of the penthouse but they will need to have the roof inspected every year so they need something that can be removed. Will this be also be not noisy for our neighbors below?

Great vid. I raised the volume cuz I couldn’t hear a word. And then the outro music came on and I almost had a heart attack.

Can this deck be installed over a GAF Liberty SBS Self-Adhering Cap Sheet? I live in NYC so we have cold winters and hot summers.

Will this system work over a concrete patio here in the PNW?

Matt, pleas do a video on GRP roofs. I do not understand this country's aversion to them. They are the norm in other countries. 50year roofing

Is there any reason I shouldn't lay evp plank flooring over an epdm "flat" roof? Or if you'd prefer, is there any way this would be advisable? I'm looking for an option for a lighter weight rooftop deck.

CBC requires joist space below a balcony to be ventilated. How was this achieved on your beautiful project? The Bison panels versus decking and joists certainly saves depth. The video is dated April 2018...Any long term feed back yet?

The price on that must be nuts, also do you have to raise the railing as well?

I like this. My only question is: do you have to remove the entire deck before a hurricane since they’re not attached to a roof?

I wonder if so much depth is needed. This is probably spec for this specific product but if there were a standoff product that requires only an inch or two from the roof surface (not including the depth of the deck boards) then a guard rail may not be required to be added...

How did those walls pass code height? With the deck they are now even lower.

Could something like this be done in the Basement floor instead of Concrete

What about up lift during a storm since it isn't attached in any way?

What type of perimerter rail detail is recommended where the is no parapet ? Love the look but contemplating this type of system that needs perimeter guard rails an likely perimeter, roof surface to deck surface, dams to stop wind uplift.

Locked in with a screw on each corner, but that means in order to remove a panel in the middle you'd have to release 9 surrounding panels to release the middle one. (by the looks of how it locks into each panel). Or am I missing something?

What do you suggest with yearly maintenance to maintain the color?

Its a constant level lake because its not a lake! Its a river with dams on either end.

I have an existing flat roof deck that has a torch down roofing material over concrete. Can these pedestals be used to support joists to install a more traditional deck? Additionally, these pedestals just float and are not screwed into the roof… right?

Nice.

what if you want a concrete deck over living space? How would you do that?;)

I'm assuming this Bison system would not be an option near the coast, being they are not locked down to the main framing of the house. There are to many risks for wind storms for this to be a viable option.

Is it safe to put a pedestal deck over a bitumen flat roof? I’m concerned with slippage due to heat pulling on seams.

what about the uplift, surely without hurricane straps this will fly through the outterspace 🤣

Can composite decking be installed over the Bison supports ?

I live in Florida so wind loads and uplift are issues down here. Are there any provisions with this type of decking other than the weight of the epie?

Where can I get the wood panels from?

Anyone know how the price of Bison compares to conventional wood sleepers?

It is not cheap but it does work ! Every roof deck I see it’s worse from just a deck being built to stay and now few years later or less it’s leaking but now A gotta pay some one to disassemble the deck just pin point leak then to repair it’s another bill then rebuild deck

I know you say the panels are removable, just have to remove the 4 screws, but it looks like there is a disk at each corner that the screw goes through locking all 4 panels together. How do you handle the disk during removal and reinstall?

what's holding the whole deck down? Is it just its own weight?

Where will I buy the 2x4 panels or where can I order them?

Can I live there?!?!

where can I get one of those build hats?

Did you make or buy the Ipe panels?

So i have a flat rubber roof with a pitch. I want to raise and place a deck. Can a jacuzzi be placed on top of deck and pedestal? I know the structure is able to handle the weight. There is living space below. It was and addition to the house over looking the woods in the back yard. So will it hold a jacuzzi do you think? or should i place directly on the rubber roof.

This is exactly what I’m looking for! Would it be safe to bolt a lightweight pergola to a deck like this? Thanks!
