ᐅ Smooth roof tile or curved roof tile?

I believe by "smooth" he meant the shape, not the surface, so rather flat, without any curvature.

Sorry, I meant the "smooth, glazed" surface. You’re probably right. 😉

I can’t support the suggestion to choose a zinc or aluminum roof covering here because installing a photovoltaic system on such roofs is significantly more complex and therefore more expensive.

Why is that? No tile puzzle, no roof hooks, less leveling, no cutting with an angle grinder. On small carport roofs, you can even skip the substructure.

A zinc, aluminum, or copper standing seam roof is installed on battens. That alone causes higher costs.

How exactly would you skip the substructure? Are the photovoltaic modules supposed to be glued directly onto the seams?
I would really like to see that.
By the way, what exactly is tile puzzling?

I would appreciate it if you could elaborate on that.

Actually, gluing is possible—I have already done that on a motorhome. For a carport, though, I would rather use screws. And yes—just directly on top. There are mounting systems for that. Unfortunately, I’m not allowed to share links.

What exactly is “tile Tetris”?

Raising tiles, installing roof hooks, cutting tiles, putting the tiles back. If things go badly, half the ridge will need to be uncovered. There is often a lot of work at the eaves as well. For me, about 5% of all tiles were removed at least once. That part took the most time. With a metal roof, you just screw through it, which saves a lot of money and time.
However, I don’t have the aluminum or copper you mentioned. It wasn’t supposed to be especially expensive. ;-)

A standing seam roof always requires a fully boarded substrate. On top of that, a random fiber membrane is applied to reduce drum noise. Only after this can the metal sheets be installed. The standing seam system needs a solid and continuous base.

Adhering modules on a motorhome with a small module might be possible. However, for a roof with modules measuring 1.5 to 2 square meters (16 to 22 square feet), this is absolutely incorrect and not according to professional guidelines. The wind uplift forces are far too strong for bonding alone.

There are the most adventurous installation methods out there. As an expert, I always find this amusing. That way, there is never a shortage of work.

Screwing through a metal roof—goodness no! This will compromise the entire waterproofing.

The ridge remains completely unaffected during the photovoltaic installation. Minimum distances to the roof edges must, of course, be observed. Naturally, small edges are ground off to mount the brackets. This only serves to ensure the roof’s rainproofing; it has nothing to do with fitting puzzle pieces together.

The important thing is that the roof remains perfectly watertight after the photovoltaic installation.
