How much does the top door panel stick above the header? More than 8"?
Cut the bottoms off the two tracks bolted to the opening, drop it under the truss. Although you will likely have to used low head room brackets and modify them to get the top panel to seat right at the top. |

Quote HistoryQuoted: sucks they are like 4 hours away If they custom made those, do they have an engineer on staff that could make you a modification drawing and you can do the work? I doubt they would do that, but I'm just throwing out ideas. Your sketch you made with the white lines actually looks like it could work, but I'm not a truss expert. |

If it is, I don't think there would even be enough room above the header for a roll up. My roll up 8x8 need 16 or 18 inches above the header. door is 13'6" I'm not a math wizard or a garage door installer. Something doesn't add up. You need the height of a 13-6 door but your truss height was only 12-10 , then the trusses after that are only 12-10. What is the height requirement your storing and how long is it. Will it hit the next truss even if you get the height needed on that truss? |

What's the tallest thing you plan to move in through the door?
Could you modify a door panel or remove one panel to resize the door down by about 12-18" and then drop your door header and track system to match? |

But then because of the angle of the dangle the rear of the track is like a foot lower that the door opening. I am about to make a youtube |

If you cut it wrong, you have to buy new verticals. Only way it would work is if you have excessive panel above the door and could keep the top roller below the radius. You don't have enough panel to do this after seeing the video, don't cut the rails. |

What is the radius of the tracks for your door? If you can go smaller, that would help.
Often, in these low clearance situations, they go to a tight radius track and sometimes even do a double track for the horizontal rails. I'm not an expert, but my brother in law has a side business doing garage doors and I've helped him out a few times over the last few decades, so I've seen a couple low clearance and low headroom installs. ETA, I see this was already covered. |

You would have to place it in a program like RISA or STADD-Pro, and run an analysis. You are cutting the main tension member of the truss (under gravity loads) or the main compression member under high wind loads (yes it does both). Granted, your max tension and compression is near mid-span of the truss. But you can't just cut it. You must do something else. I bill my time out at $175/hour, but I'm not licensed in your state. Someone analyzing it would need the original design drawings with dimensions, sizes, and steel strength.
I think it would be cheaper to return the door and get a sliding door, roll up door, or shorter door. |
