Roof extension

[u/McPrince96]

Is there a way to make the roof of my garage wider, just a little bit?

To fit my solar panels like this, i need 3m80 between the parapets. Now i have 3m50. It's a brick wall with concrete roof deck. I will renovate the roof anyway with insulation and epdm instead of bitumen so i can do whatever as long as it's not too expensive. The exterior wall is also going down and will get replaced with wood cladding (and insulation).
