In this episode of the Garage Door Installers Podcast, James looks at one of those problems that can turn a straightforward garage door survey into something much more complicated - **low headroom**…

You've got all these sections that are going to travel up vertically and then run back along tracks across the ceiling.

So immediately, you're not just thinking about the size of the opening anymore.

You're thinking about the space above it, where the tracks are going to go, where the operator is going to sit, what's in the way, what's happening with the roof.

And that's before you even start worrying about whether someone's got a light fitting hanging down in exactly the place where your track needs to be.

You can have two garages that look virtually identical from the front, but once you get inside, one has got loads of room above it, and the other has got a steel beam running straight across the ceiling.

And suddenly, what looked like a really straightforward installation isn't straightforward at all.

And this is why when we talk about headroom, I think one of the most important things to explain is that's not just about a number.

You might have somebody say, I've measured it and I've got about 200mm above the opening.

But where is that 200mm? Is it completely clear? Does it stay at 200mm further back? Is there something sticking down? What's the construction of the ceiling? What's happening at the sides? What door are we trying to put in? What mechanism are we using? Which operator are we using? Because all of those things can change the answer.

And this is where you start to realise why a proper garage door survey is actually quite important.

You can't just measure the width and height of the hole and say, yeah, that'll do.

you've got to understand what the door is going to be doing once it's fitted and one of the interesting things about low headroom is that people often assume it means they can't have a particular type of door and sometimes that's true but quite often it doesn't it just means you've got to think about it a little bit differently take a sectional door A customer might say, I'd really like a sectional door, but I've been told I've got low headroom.

But there are different track arrangements available, and most suppliers can offer a low headroom solution.

Now, whether that's the right solution for that particular garage is another question.
