Raised roof to cab sheet metal

Hey all!

New user here,

I am looking forward to building a Skoolie soon with a flat front rear engine bus, and I too will raise my roof. The method that I plan to raise it to cut along the window channels, and over the cab (so it will basically be one of those two height roofs).

My question is how are people managing to bend that sheet metal around the curved higher roof to the now shorter portion of the roof?

I am assuming the use of multiple smaller sections of sheet metal riveted together would be easiest? Thanks!

PS- To smooth this out should I use fiberglass?

Use construction paper to form templates for the metal cutting.

THIS is a great thing.. Cardboard and blue tape mock ups!


the rather thin inexpensive Sheet metal duct panning is also a good way to mock up things because its easy to bend and such.. so you can make sure you can actually make the final piece out of real metal...



just wear gloves.. paper cuts from cardboard suck.. Metal cuts from sheet metal BLOW...

I also was thinking of a cardboard template that could be transferred to sheet metal and cut in a single piece. Less chances of leaks.

We used "poster board" paper and trimmed the steel down a bit as needed.

And back to one of the original questions...


No. Bad idea to mix sheetmetal & fiberglass. Stick with all metal.

If I had not seen your mad metalworking over on your build thread I would have thought "no way".

Having looked at some of your work on your bus in your thread. I am a bit envious of your metal skills.

That's the word I was looking for. Cheap like $1 at box store. Have used this method before in racecars and shaving engine bays.
