I've got a question for those of you with a similar setup to my shop with a 2 post lift. I have a 40x30x12 with 3/12 roof. The shop has 16'x10' doors on one 40' side. I plan on getting a 2 post lift and placing it on the far right of the shop (not determined which lift yet, most likely a 10k lift that stand at 12' or so) and I'm considering installing the doors to follow the pitch of the roof at about 12" under the purlins. My question is, is it necessary to install the doors following the pitch, or is it worth the work? I don't want to disturb the lift if I have a vehicle on it while lifting the door. Will a car or truck disturb lifting the door if installed like normal? I believe the answer is yes, that it's necessary but wanted to hear from those that have a similar setup before start to modify the tracks.

If I'm understanding your question correctly, you're asking if the door rolling back parallel to the floor at a distance 10 ft from the floor will interfere with a vehicle up on your lift. If I have that correct, the answer is yes, I don't see how you could put a vehicle up on a lift, the top of which will be higher than 10 ft without the door interfering. Worse, the frame and track will always be in the way.

I have what sounds like a similar setup. Mine is 36x36 with 10x10 doors. My two bays are 12 ft wide between the trusses I have a low rise lift (MaxJax) so I can lift to the highest position while keeping the top of the vehicle below 11 ft where my lighting is on the truss bottoms and cross members. Here are some photos of how the roofline doors look and the room they provide.

My prior shop had a 10k Bendpak centered in a 23’ deep (inside) bay with a follow-the-roof 10x10 door. The tracks ended 1/4” short of the posts, but the door stopped at least a foot from the posts.

100% worth the effort to modify the track for roof pitch. I had to do this on my attached house garage when I had a 4 post installed for car storage. I had vaulted ceilings in the garage but the track/door interfered. I modified mine so that I could stack 2 smaller cars while building my shop. When you go this route you can either removed the opener and keep it as a manual door or you will have to installed a jackshaft style opener if you want to retain remote open and closing. I opted to just lift the door up and down and held it open with a pin installed in the door track.

Everyone, thank you for the information. It's exactly what I needed to see/read. Thanks for the pictures. Will definitely continue with modifying my tracks with roof pitch. And yes I plan to use the jackshaft openers.

I have an 8ft tall door that goes up the wall to the 12ft ceiling by my lift. It works out great because half of the door is along the wall.
I wouldn't have it any other way, even if I didn't have the lift.

Be sure to include your track design when you look for the opener. A conventional track has the door going to horizontal when up so the load on the motor actually decreases as the door rises. W/ the roof following tracks the weight of the door almost doesn't change. You may also need different pulleys for the cables.

It was necessary for me. That's about all I can say.

With the 3/12 slope, you're not going to get out of the way much, but I suppose it'll be worthwhile.

I built a 427 Shelby Cobra too and I'm extremely happy I bought my MaxJax for low ceilings to aid in building mine.
