Only Matthias could see the genius of putting a roof under the house.

Pretty smart! I like the simplicity of solving a problem with reused materials and minimal effort!

I have the same thing under my second story deck. Had it up for about 5 years now. No problems with it even after the Alaska winters.

Nice! Every time I see you with the light Hitachi drill it makes me smile. They have to be the most durable designs of drill and hammer drivers for this weight class. I've had a set for over ten years and my son built his house using one. We've certainly abused the tool, but they've never broken.

I did this under my deck that covers my cement deck underneath. I didn’t use straps below the sheets. I used j-channel at the end against the house and sides. On the side that the water runs to, I turned a piece of j-channel on its side to make a small gutter. It works great unless it’s a real downpour. It has been there for 20 years with zero issues.

This is the kind of project that looks great and I would like to see it again in a couple years to see how it holds up. Great idea. Great video!

Best thumbnail on KZfaq this year.

I like that he had placed the toy wheelbarrow there just so he could casually say "not that one" :)

My father-in-law did something very similar to what you did, thought it was a little lower (so a bigger gap between the deck and the "roof". The raccoons loved it. :)

I've got a fiberglass deck that is about dead.. and that is EXACTLY what i envisioned doing to keep the stuff stored underneath from the rain.. thanks for removing the doubt from my mind!

Watching you start those screws with a hammer reminded me of a trick I learned at my old job. When you're installing metal roofing, stack it all up and drill pilot holes through all of the sheets at once. Only takes a second and you know your screws are all going to be even.

When you see a thumbnail like that, you have to click.

When I put a roof under my deck (two story house) I was crazy. Who’s crazy now, family of mine? I’m so totally vindicated, now!

I did the same thing but had to remove it a few years later. I accounted for the pitch so that water would properly drain but didn’t consider the amount of debris that would also accumulate (small organic matter, leaves, dirt) and eventually that debris built up and restricted the water flow. It caused problems with mold, harbored mosquitos and eventually rotted the supports. Hopefully you don’t have these issues.

I did the same thing 15 years ago under my deck using corrugated plastic sheets from home depot. I used 8' 2x4s bolted in the middle to make an "X" support to hold the panels over my head during installation. Its worked great. Sure nice to have a usable patio under my deck during the rain.

Here in California they sell a kit like that but I've seen them trap moisture and cause dryrot. It may not be a problem in your one little area.

Great job, I did that on my second floor deck to keep stuff from falling through the gaps to the first floor deck.

Well... it's about time you came back to KZfaq... I recently bought a very large swingset playhouse second hand. I was thinking of turning the lower level into a garage for the kids power wheels and etc but was affraid that a roof I put under the deck wouldn't work... I now feel much better about my plans.

I'm happy to have found your sentex homepage with all its very interesting links. I read your, "Why computer user interfaces stopped evolving" and noted your, "There are things that could be done better, but being able to comprehend how the system works is much more important to me." I've thought the same for years, i.e. I want to know how and where things work and are stored so I can take control of the computer. Newer interfaces that hide the works maybe great for routine work, but they defeat creativity, manipulation and and problem solving by the end user. ~~ I come at this from close to 40 years working with various systems starting in 1967 on an IBM 360/20 and a card sorter.

I was expecting something way over engineered! Nice to see Matthias can be a mere mortal from time to time.

A man with enough milk crates can change the world

Your grass looks beautiful

Looks lovely! At first I was wondering what you would do to prevent pooling but when you started screwing it in at a slant I realized the simplest solutions are sometimes the best!

looking forward to the gloating update when it's worked perfectly for 2-3 years :-)

Just a tip; Moisture coming off the ground can be even more significant than moisture coming from the skies, especially when enclosed. If these items were stored on the grass anyway it won't be any worse. But if they were previously stored on a paved surface it could well be.

I really like the way your brain works and the results.

Simple material, simple process. Very good to create a new space.

Done this several times for customers. Fasten it better though. And a gutter along the bottom is nice. But he just needs a small area and it doesn't have a patio underneath. Quite functional the way he did it.

Maybe a tiny bit of ice. Or a foot of ice as it melts down from the wood deck and refreezes on the metal. Time will tell. A great idea, have to try.

Awesome. We did this for our upper deck above the back patio so we can go outside and not get wet. The deck is also a roof. Works great.

I have a large below-grade water tank that sits adjacent to the house at a distance of about 20". It consists of 4" thick concrete walls, and a 4" thick cover which sits flush across the 4 walls, giving a nice square finish. The dimensions are approx. 20' L x 8' wide x 8' deep. It is in very good condition - no cracking or leaking and the roof seems to be structurally sound. However, I would like to move my water storage to a location more accessible to the animals and the fields, and I don't want that water so close to the house. And, at the same time I also need a root cellar and this seems perfect for the job. But, I don't like the idea of a heavy concrete slab overhead ... so I figured to remove the concrete cover, replace it with a treated wooden frame to act as a decking surface, but with a metal runoff below it, as Matthias has just done, and then attach the entire unit as a skirt to the upper portion of the walls. I think I could achieve the necessary water-proofing, air-flow and and safety this way. And, as a bonus, I end up with a decking area just next to the house. Does anybody have any opinion or experience on something like this ?

Mathias du bist der Hammer! Immer mit außergewöhnlichen Ideen

Well as a Carpenter I think you did a really great job two thumbs up 👍🏻 👍🏻

I think you are a good candidate for cirque de soleil. Best acrobatic presentation gut gemacht Gruß Thomas

Nice and simple solution, didn''t expect less.

It would make for an excellent rainwater collector too

Pine needles and leaves may require periodic clean-outs. Perhaps you can spray a hose through the deck to rinse stuff off. Here in Oregon it would be green with moss by Spring.

Impressed Your fan from Morocco

I've done this for a customer before. Great way to use the space

I saw an under deck system at a home show a few years ago. I think it cost many times what I would pay for the deck itself. This is a much more practical solution.

Nice always like your innovation. Keep it up. Miss your regular videos.

done something like this under my deck at home - very effective and didn't cost a lot to do.

We miss your big builds :(

I've been meaning to do something similar at my house. A good 20 feet under my deck is a concrete pad that's always gross from rain dripping through the deck. Been meaning to create this kind of sub-roof to channel rainwater off into the yard, leaving the concrete dry.

Looks like a neat idea, I thought about doing my deck but unfortunately we have a lot of pine needles at our location and I think it would be difficult to clean them out.

Roof under the house... hammering in screws... Love it!

Perhaps you should revisit these projects and tell us how it worked out. Maybe a video about several of your old projects.

I did this same thing about 10 years ago and yes works. I have an eves trough in the middle to pick up diverted water.

Haha! I did this under my entire deck this spring to keep my cushions dry on my patio furnature on the porch below. I used flashing and caulking to shed water over my beams and put the roofing between the beams. It's not 100% watertight but it was never meant to be.

I would have used 10 screws to hold it.

Ha! This one of the first details I learned working as an architect in Toronto in the early 80s. Variations include tarps and that cheap plastic roofing.

Great idea 👍

I am planning the same thing, except with a frame and slide out tray for a brush cutter. I have a lot of space under the deck that would better serve as a 3 foot garden shed so that I can pull down the horrible leaky ones and install more decking.

I did this exact thing to the underside of an 8’ high wooden deck.

Good idea, only issue I see is if it's particularly windy and snow gets blown in from the side. Of course that could be remedied easily though

The critters are loving you. A cool dry place to be.

Great idea nice & dry.

I did that below my deck 40 years ago, my sheets were fiberglass and no problems with wind or snow.

The need for used steel siding intensifies.

2:10 Those sharp stones must feel good on the back. lol

We did that and had squirrels there the next year. It does keep the stuff dry though! Good to see you with new content and good luck with tendinitis.

This should work in the winter as long as the deck above the "roof" is kept free of snow or is not in the winter sun. Big problem in Colorado is the sun melts the snow on the deck when the air temp is below freezing which runs unto the water collector below and refreezes. Then the roof gets torn off the deck. No big deal in your case if that does happen.

Matthias! You need to market your version of yoga!😁

“Tiny bit of ice” is going to become a bunch of ice during spring when the snow from the deck melts onto that roof and refreezes but doesn’t have the sun to melt it off.

Great use of space. Personally I'd round over the timber edge on the end to avoid head/back injury while moving items in/out.

You will have an issue with leaves and other stuff that gets thru the deck board cracks and tend to stop up the channel where the water will run. I end up removing couple of the deck board once or twice a year to clean out the channels. I do have a tree right next to my deck, so mine might be worst than most.

If you decide to do this, make sure you have enough slope to drain the water. How do I know this? 350+ Square feet of this under my deck, now it's own ecosystem of sludge and rotted vegetable matter. Lovely on hot days! Oh yeah, the squirrels love it under there as well.

Great, very well thought out, greetings from Spain.

It's always a good idea to keep your deck clean and dry

Matthias, three points: 1./ the deck is the roof, that was a ceiling; 2./ "And it worked out in the end", actually, you had a workout on your end; and 3./ you exhibited very good foot handling - what sports did you play?

Reading the comments I realized that using all available limbs to force materials into place is not so common, as I thought. But, yes, it is nevertheless funny (especially watching it upside down).

Milk Crates: Man's Best Friend 2.0 lol

Hope it's not too noisy with all the dripping of the rain from the deck

Even if you have to buy it new that sheet metal is comparable to the cost of a plastic tarp at Home Depot (on a square foot basis) and lasts decades longer.

@2:12 Today on mousetrap monday we'll be catching a wild woodworker using a novel trap invented by the that same woodworker.

good idea, keep up the great work!

You may want to consider some kind of eaves trough to divert the water away from your foundation.

this video is the best video in the world

Great idea

Quick easy shed. Thanks for the video.

this idea is great and i want to do the same now.

Crazy! I was just thinking of doing something very similar just this morning.

Thank you for captions.

Sometimes is just about getting it done.

Look forward to seeing you with the Cirque du Soleil touring company

2:49 Yea man, I recently saw someone test different screws holding strength and the weakest one could hold 300 lbs each.

Most people would just the the wheel barrow upside down :)

I really hope there won't be any wasps moving in there. I'd keep an eye on that place every now and then during late spring/early summers.

I'd like to do that for our back deck, but I'm worried some form of critter will move in. Another concern might be debris such as leaves, grass cuttings, etc, could build up and be a fuel source should an ember get blown in there.

Seems like if you had used cabinet mounting screws those support bands might not have gotten thread bound.

Are we all just going to ignore the horribly installed deck post saddles? What were they thinking

Thought this was a hideaway for the kids!

I have occasions where I watch your videos for hours. Some I seen before. Just listening to you talk is alright with me,,since you make sense usually!! lol

when are you going to show us your apocalyptic under ground shelter , like the one in ( blast from the past )

i have a project for you... well for me actually... more specifically for me, when i'm old. i want to modify my two wheel wheelbarrow with a motor to make fetching the daily firewood in the winter, easier. my woodshed is maybe 500 feet away from the garage door... uphill empty and downhill full... i want to add an electric motor to the wheelbarrow... have seen drhack do one one a single wheel one... question is, if it's a two wheel, do you attach the big sprocket to one wheel, or in between - that would mean attaching the sleeve that goes over the axle to both wheels... and he uses what looks like a windshield wiper motor... is that really powerful enough? it only has to make one trip a day so doesn't have to have a huge battery - that could come in after each trip and be put on the charger again.

Mini tractor shed build

The wild animals are going to love that.

wondering how it really work in the winter in terms of sun melting the snow on the deck and water dripping and freezing on the metal?

Thinking about Matthias' early remark about the wind making it rattle. Even though it's now secured from that problem by virtue of the added framing, I still wonder if there's enough lift from the wind to move and work at it over time, perhaps fatiguing the metal in those 9 screws, eventually breaking them? A lot of their length is exposed between the metal and the deck on the middle and lower positions. I suppose it depends on how much wind it gets?

Functional, every-day Joe for the win. However, it looks like the mid and end spans are very shallowly attached. Should add yet another camera, and we can all watch it every spring to see how long it lasts.
