ᐅ Cut Out Roof Section in Garage Area – Experiences

Hello!

Our general contractor (GC) informed us that we need to notch out the house roof in the garage area because the garage roof is higher than the house eaves. Unfortunately, we don’t understand this at all, and the GC didn’t have any picture to illustrate it.

For some background: we are building the garage ourselves (with a friend who is a mason) and were actually ready to start already. Then the GC said we should wait because there were height issues. We can begin once the roof is adjusted. This is now done, and the current instruction is that the house roof must be notched out. Since we have absolutely no knowledge of this topic, my question is whether there is any alternative to notching out the roof? If not, do you have a picture showing what that looks like?

So, after the appointment, here is an unsatisfactory conclusion:
The general contractor considers it disproportionate to tear off the roof just for a 25cm (10 inches) knee wall. They offer about 4 as a price reduction. That’s ridiculous. According to the lawyer, the argument about disproportionality is also completely nonsense. We have an appointment next week with an expert.
What other disadvantages does the missing knee wall have, apart from having less space in the attic (which is only meant to be used as storage), and the fact that the roof starts almost immediately above the window (after two rows of facing bricks), so I have less light inside the house and the exterior looks cramped?

I can’t follow his reasoning there.

The explanation given was that the software automatically models the garage 25cm (10 inches) lower than the house. However, in the plan it is only 10cm (4 inches).

Brazen nonsense. The mistake and responsibility lie entirely with them. Rebuilding the garage lower, including redesigning the driveway and changing drainage, will cost you far more than this token compensation. And your argument about light and appearance is not dismissed by that. Still, it’s not certain you will definitely win in the first instance, and construction may be delayed. Covering the additional effort of the roof cutout at their expense plus $25,000 for the 25cm (10 inch) forgotten knee wall seems to me a fair mediation outcome.

The dimensions of their garage avatar/dummy should not be taken at face value in the planning; they have to use the actual measurements. These have nothing to do with the type of door construction. Although the connection is absurd, with

They thought we’d have issues with the height anyway because we chose an up-and-over door. But they knew that from the start.

they clearly admit they were always aware of the real garage height. Tar, feather, and flog them—and then do it all over again :-)

There is news... According to the general contractor, no knee wall was planned; instead, the 25cm (10 inches) mark is supposed to indicate the bending point. Is this correct, or is he trying to fool us? In his opinion, the height issue now results from a larger roof overhang, which he says he gave us as a gift. According to the plan, it should be 50cm (20 inches), but currently, it is 75cm (30 inches). He says he did this on his own because it looks better on a bungalow.

How is a knee wall usually represented in a drawing?
Is what he is telling us accurate?

Whatever is supposed to bend off from something. In the drawing, a hatch pattern looks like it could represent a row of stones or similar. But even just a wall plate (foot plate) could be possible—nothing is really clear there.

An additional 25 cm (10 inches) roof overhang at a 25° roof pitch naturally shifts the eaves by nearly 12 cm (5 inches).

A knee wall—which is rather uncommon without a living space conversion and also not typical at this height—can be identified as a wall segment below the wall plate (here unfortunately not clearly visible in the drawing). However, when looking at the attic floor, you can see if there is any "masonry" beneath the roof structure. The knee wall is measured from the top edge of the floor (though inconsistently, whether from the raw or finished surface).

Is this the drawing for the building permit / planning permission or for the construction planning?
