How To Fix A Saggy Roof 

Thanks so much! So glad the video was helpful! :)

Interesting. Can you give us a pointer to you tube videos?

I’d need a visual explanation 😂

So glad to hear it was helpful! Thanks! 😄

Thanks! Glad I could help!

So glad it could help. Thanks!! Good luck with your project!

Thank you! I’m very glad you liked the video!

Oh wow! Sorry to hear that. Thats a pain. The snow load might have been too much for the trusses to support. I'm glad the video could help! this should greatly increase the strength of the existing trusses.

Hahaha 😂 Thanks for watching! 😁

Haha yeah it was not fun! Good luck on your!

Awesome! I'm glad the video could help. Thanks!!

We measured a rafter that wasn’t sagging. We cut it close to the length we wanted then held it up in place and marked the angles.

Sure, the angle on these will depend on the angle of your roof. You can calculate the length and angle by going to a truss that is not sagging and hold a 2x4 up to the truss and strong back. Then run a pen along the strong back to get the angle. Cut and then repeat the same steps to get the angle and length for the truss. If it takes a few tries that’s fine. Once you get one done you can use it as the templet for the rest. Hope that helps. Thanks!!

Thanks, I try to make it as understandable and simple as I can. My farther in law was a huge help with this one.

So glad! Thanks :)

You want to aim for a load barring wall on the floor below. The previous owner of this house opened up the space below and took out the walls that were supporting the roof and installed a main beam down the middle instead. We tried to install the strong back as close as we could to that beam. If the wall doesn’t r support beam is too far away you can get 2-3 feet from it and that worked for us.

Agree. I thought surely someone caught this.

There were a few vents but they weren’t located in this section of the house. There was loads of wiring that in a previous video I had to fix and organize. Because of that it was already out of the way of this project. The ductwork is in our basement.

I'm glad the videos could be helpful! Good luck with your project!

Thanks so much!

Glad it was helpful! Thanks!!

Thanks! 😁

Yes, but the wall here was taken out by the previous owner and they caused the sagging roof. If possible it’s easiest to go off of a wall but this is an example of how it can be done if that’s not an option.

Thanks! it made a very noticeable difference from the outside out our house :)

Very true. It would be easy to lose your balance and fall through the ceiling.

Thanks so much! Good luck with your project!

So glad the video could help! Thanks!

We measured down from the peak of the roof on each side and ran a chalk line string to make the placement. Thanks!

Ok thanks for the reply!

Thanks, I appreciate it! 😁

We held up the 2x4 next to the truss at the angle we wanted it to support and had the board just long enough to reach half way down the rafters. With the 2x4 next to the rafter we used a pencil to transfer a line from the top of the rafter on to the 2x4. After cutting that mark the other angle is exactly 90 degrees from that first cut. A speed square works well for getting the second angle. After that we placed the the cut 2x4 on the strong bad in place but left the 2x4 a few inches too long so that we could place in next to the truss and mark a line for the top angle. Hope that helps. Good luck! Thanks :)

You are correct! Thanks for setting me straight! 😂

Thanks! Yeah it may not work for every situation but it is a good option to explore along with other ideas before jumping into a repair.

Your very welcome! I’m so glad my video could be helpful!. Thanks! :)

Scary that you are a roofing contractor and don't know this already. It's like a licensed plumber watching youtube videos to learn how to do plumbing.

There are a lot of bot comments on RU-vid. If they say something illogical or claim to have literally the exact same scenario at the same time as in the video, be suspicious.

It wasn't too bad. With the two of us, we finished it in one afternoon. It helps to do this in the fall or winter seasons as the heat of summer can be hard to work in. Thanks!

Thanks! Yeah that was one of the options we were thinking about. Hopefully because it is only 2 feet from the main beam it should have plenty of strength. Also the joists are actually 2x6s. I’m keeping an eye on it and so far all good! :)

I caught somewhere in the video around @8:30 - 8:45 that the father in law was eyeballing the level across a couple rafters with the 2x4. You could probably buy a proper level and use that to figure how much you need to push/pry the rafters. Definitely would want to get one of those 4 or 5 foot levels so you can easily measure across several rafters.

Haven't done the job yet, buy I used string to tie from one end to the other. Both end rafter boards are tied into the home. I find it easier to eyeball the ones that are sagging.@@mustache2295

I probably wouldn't pay more than $600-1000 that a big price difference but that will depend of the amount of materials and difficulty of the project. This project took two of us only one afternoon to complete.

@@SimonSaysDIY THANKS VERY HELPFUL

@@SimonSaysDIY how big is your roof?

CE

Thanks!

Haha 😂 well I think it’s safe to say the roof will no longer be sagging 😁

It's not additional, it should have been there from the beginning.

Thanks. My father in law showed me that tip and it worked surprisingly well!

Also wondering about codes, and putting weight on the ceiling joists

Why not just go right back to the center beam rather than make those strongbacks and cut/secure them properly so they do bear the load?

If the angle is too steep, what about making a web?

Thanks! 😄

@@SimonSaysDIY your welcome.and the best part is they way the work was done and your guys movements and how delicate you were in the process means you actually enjoy what you do actually take pride and respect for the project.hard to find true people like this these days.👍

So happy to hear that! :) Thanks!

Thanks!

Thanks!! 😁

Thanks! 😄

Thanks! I'm glad my video could help. Good luck with your project! :)

Thanks! 😀

Great to see a Christian sharing the good news about Jesus!

Thanks! No we didn’t have any issues with the roof after fixing this. However a few months later our home insurance made us replace our roof because of unrelated age issues with the roof. Hope that helps!

@@SimonSaysDIY Man, I'm in the same situation. Shingles are old, but I'm trying to fix sagging rafters and a deflected ridge before I begin.

Glad to help! Thanks!

I did ask a REAL Professional and he helped with the project. It was actually fixed correctly. However, there are also many other ways that this can be done and this solution won't work for every situation. Thanks! :)

​@@SimonSaysDIYthis is actually false. You put a bandaid on a scratch... And never took the band-aid off or cleaning the cut so now it's going to get infected and cause issues elsewhere.

too dumb. Watch again, take notes, pause, don't be an idiot.

Thanks, But if it was done right then the roof wouldn't be sagging and supports missing. This was a typical BAD professional job. Supports for the roof taken out and never replaced. wiring cobbled together and scattered everywhere. Missing electrical box covers exposed wire connections and loose insulation moved during the remodel and never put back. Also, I know my limits so this is why I asked for help and had a real professional contractor advise and help with the project. Thanks for the feedback though! :)

I find that really hard to believe and no there is not so many way to fix a roof! I have never ever seen a roof fix like that come on ! It had collar ties !!!! PERIOD! I really do not care what you do! However you put it out on YT like it’s the right way??? The saying goes if you find yourself in a hole the 1st thing you do is??? STOP DIGGING! If I was fixing that roof 1st off you go to an engineer and hv your plan approved! It’s a roof not an office wall! I seen the braces and collier ties and NO SAG! U placed to much crap on the ceiling and eventually that’s a problem! Ask a contractor! Not the guy down the street that flips homes! This is my problem with YT! If I was the contractor and I seen your video and stating it was done wrong trust me I would see you on the legal field of play! Your not a carpenter or a contractor so that means you hv no idea what your talking about? Yet if you were a doctor and I had one of your patients on tv pointing all your supposed mistakes u would be pissed! Can you calculate rafter cuts for a roof? Figure your bd ft of needed lumber ? Use your framing square to figure the angle of my skirt board? Calculate rise/run for stair lay out? Guys train years to learn this craft & you buy a house open a YT channel and start pointing out all the carpenters mistakes? I am wasting my time ! Pls hv some respect!

@@SimonSaysDIY don't feed the grizzly construction trolls

Could you do a video showing how you would do it. This seems good to me.
