I did it by myself !!! I’m a 62 year old widow and I followed your instructions and materials exactly. My late husband had most everything needed in his shop, even the concrete. Thank you so much for your video. I am also using mine for firewood storage since I have had to learn how to cut my own for my only source of heat.

[@christophermhudson09]

That's awesome to hear, about you building not about your husband, so terribly sorry to hear your loss. My wife and I are 31 and 33 respectively and we're just coming to the time in our life where we're giving thought to the later years, you know how it is in your 20's lol it's like 30 is never going to come and you're never going to get old..... But I cried thinking of the hypothetical situation if something were to happen to me at work what would she have to do if I were gone and it were only her and our three children, I pray she has your strength and willpower to keep accomplishing things. Sending my very best to you ma'am 🙏

[@FoolyLiving]

[@jackiesnowflake2255]

Just turned 69 and I'm going to do the same on the back of my house

[@fxrivrgirl]

Same my adult kid has no interest or skill & i want a simple way to build a awning or lean too roof over north door & have a old freezer out in elements I want it dry about 4 feet out away from house & maybe put west end 4 ft wall to cut that north west wind & snow a bit. My house is 140 years old small 1 story prairie house. Have been looking for a simple way to get my roof extended that I could manage. Ive you tube surfed for 3 years trying to find something like this. Im not living in it just want the rain/snow off & get that mess away from house where we walk in. & maybe hang a couple flower baskets in summer. I'm so tickled.

[@ronfults3844]

This project wouldn't have been possible without the good helper you had. Kudos to your little helper!

[@fallbrkgrl]

Seems pretty straight forward...then again, I'm a 59 year old woman who is trying to learn how to do things myself from watching videos. They all seem fairly simple. My first attempt at building something was a decorative fence, using wire cages, and rocks to hold the 4x4 posts. No matter how many times I measured anything to do with the project, I never seemed to be able to get it right (fortunately came up with a way to hide all of those bad cuts😏). It's always way harder than I think. Just have to keep practicing, on things that are decorative in nature, until I get better at this building thing. It seems that finding a good, honest handyman to help me is just as hard as trying to do it myself. Thanks for the great video! ❤️🌵☀️⛈️🌈☮️🐎

[@garypillischafske1425]

I have always poured a pier first then used a bracket for the 4x4 thus keeping the 4x4 from earth contact. Has lasted over 30 years that way thus far. Just a thought. Great job, now I need one!

[@2nostromo]

treated wood rots at the soil line. well worth the effort to use your method.

[@zedwpd]

@@2nostromo Depends. They have ground contact wood just for this application. Or you can use a used railroad tie with 80 years of creosote, it will last another 80.

[@elenawalczyk5927]

What a pleasure to watch handy man creating something awesome! Thank you for great tutorial!

[@tonya8013]

Good job!! just a suggestion, you can knotch out the top of the 4x4 post so that the 2x6 directs load to post rather that screws. makes for a stronger build.

[@PatriotDIY]

Good suggestion!

[@b-trugs1503]

Wouldn't even worry about that with something like this. That roof you could pretty much lift off single handedly. Majority of pergola's you see are held together with coach bolts so yeah, same concept

[@IGK58]

Can you translate “notch out the top of the 4x4 post….” in simple terms for the rest of us? I’m about to do this project myself and I’d like to know what you mean because I have no clue watch notching means or does other than makes it stronger…

[@kennethbowles4049]

@@IGK58 At 3:04 you see him screw a 2x6 to his posts. Instead of doing this, you cut out part of the top of the 4x4, so that the 2x6 sits on top of a notch. You just make these cuts with your circular saw and the 2x6 will fit in the opening you create. Your 4x4 top will look like it has a little edge for the 2x6 to sit on. Many call it a LAP JOINT. This will distribute the load down the 4x4 instead of on the screws you used to mount the 2x6. I too am going to build this in a few days, and I think cutting out a notch is a wise idea.

[@TruongMai-gl3gm]

[@TheKeymaster316]

I just wanted to drop a "Thank you" for the video. My wife wanted to build a lean to off of our unused shed so we can turn it into a chicken coop. I probably spent more time fumbling through the unkept isles of Lowes than I did actually building the lean to. The only thing I messed up was I went overboard on the purlins. But now that I've got one lean to complete, it's time to do a bigger one now. 😁😁 Thanks for the simple but concise instructions.

[@servantofyah1377]

We'll be building this onto an existing shed for some additional low cost storage. Thank you for the easy to understand instructions.

[@4WinterTires-uv1mr]

Using existing tools and materials to get the job done is what i was looking for. Useful no spending $, thanks for a raw video!

[@slo232000]

nice video for a simple lean to project. i would recommend at the top edge of the roof where the black metal meets the metal building putting a large bead of exterior silicone, caulk, or even roofing tar to seal out that joint. Stormwater will find its way into that open joint against the building and over time saturate and deteriorate the ledger board. Water can find its way into the shed through the screw holes too.

[@awildapproach]

thank you for saying that. I was watching this and wondering if caulk was needed. Now I know! :)

[@slo232000]

@@awildapproach welcome! my recommendation would be the tube of roofing cement, once it fully cures it is rubber-like and should hold up better over time than standard caulk or silicone.

[@awildapproach]

@@slo232000 Thank you so much! Will do!

[@tybailey041695]

Should have went to a seam in the metal siding and flashed the roof would’ve been the most correct way

[@coztod]

This detail is what I was looking for when searching YT for lean to methods, but it looks like this person is relying on the corrugated ridge to be a drip edge, which like you said it won’t, and surface tension will wrap water along the main building steel onto the top of the ledger. Thinking about caulking the ridged profile of the end of the lean to corrugated to the flat horizontal building metal, that will be a wide and varied joint to caulk. One thought is to use an L flashing horizontal on and caulked to the main building metal and overhanging the lean to roof metal, allowing a flat continuous caulking surface and a drip edge to kick the water into the lean to roof. Rather than trying to follow the corrugated undulations with caulk. Alternatively, I suppose you could make the cut on the roof corrugated metal at a miter matching the angle of the roof pitch to flush the profile of the corrugated roof to the horizontal wall surface, and caulk that. The drip edge l channel is probably more forgiving.

[@shaineriches4369]

For a non professional carpenter. Its a good job , well done bro. Got my respect man 😎🙏

[@Akaterial]

Good job. It looks great! My only suggestion would be to put some concrete in the bottom of the post hole before you put the posts in. When you put the post in the hole first, then surround it in concrete you leave the bottom of the post exposed to the dirt. It will slowly rot from the bottom up over the years. The wood acts like a straw and will suck water up into it from the dirt that it contacts.

[@blurglide]

Yeah, but then you have a concrete cup the post is sitting in. Best to put some coarse gravel down there to allow drainage while still creating a barrier from the soil

[@dylanheflin3666]

So does the ledger board just attach straight in tge sheet metal?

[@paulhuwig1434]

@@dylanheflin3666 through the metal preferably fastened into every stud you can possibly fasten to

[@cheesecrackers3928]

You need drainage at the bottom of the post. Not concrete,

[@SLKR-ek9hj]

Could bricks at the bottom help with this ? So the post sit on the brick and then get surrounded by concrete?

[@Barc7580]

Looks like a great place to add a couple solar panels

[@stephenhammersand4475]

I cemented 4 x 4 posts into the ground when putting in a fence around my home in Florida and after about 30 years the posts began rotting out where the cement was. I replaced the rotted out posts with new 4 x 4's but instead of cement put in crushed limestone to allow the water to seep past the wood. I think this might be better than cement but 30 years is still great. Thanks for the post

[@LordoftheCats]

One solution to prevent the post from rotting is to first start with pressure-treated wood. Then coat the part of the post that will be below ground with a good heavy coat of black fence post paint. I like to use two coats. Now put that on top of a 4 -6 inch layer of compacted crushed stone in the bottom of the hole then pour the concrete around that. That's about as close to a forever post as you can get. If you cut your posts in the process of the build, especially the tops of the post, it's a good idea to coat those cuts with some form of sealant since you removed the PT chemicals when you made a cut. Happy fencing!!

[@TJsVette]

Paint the bottom that will be going into the ground, I also add 4 screws going into the wood at a angle so the concrete has something to grab onto for a better hold. Add some small rock at the very bottom to allow drainage away from the wood. Make sure to tamp it down to get it as flat as possible. Since you can cut the tops like he did in the video, it won't matter if they are even.

[@PatriotDIY]

Good luck! For that application, you will want to include a peice of flashing between the roofing and your home! Just wanted to mention that since I didn't use flashing in the video

Man, this video on "how-to build a lean-to on an existing building" SUCKS!!! Nah, I'm just messing with you. Honestly this is the BEST video that I've seen so far when searching for "how to build a lean to" videos. Most of the other videos out there are way to long with way too much happening and nothing really being explained in simple terms or if it is explained it's way to much info. By the time you finish watching the long videos, you no longer feel motivated to start ypur own projecy. But your video was only 10 minutes long and yet you showed and explained the whole build plus you made it look so easy that I'm just going to start doing my project. Simple easy and straight to the point. Like I said the best video that I've seen so far.

[@andyprairiedog]

Excellent video again. Building my own lean-to type in several weeks. for mine, it is going to begin from under a roof overhang of a tool shed so the flashing won't be necessary for my build. I like the idea of blockings between the truss/joists rather than on-top perlins. I'm still saving up for those thin corrugated metal sheets.
