ᐅ Terrace Roof Deflection

Hello,
I have a question regarding my terrace roof (KD roof, 8m (26 feet) by 4m (13 feet), 10mm (0.4 inches) laminated safety glass, 3 posts). I measured the cross beams (each 4m (13 feet) long) and noticed a sag of about 5-6mm (0.2 inches) in the center at the front. Is this still acceptable, or should I report it to KD? Could it bend further? After rain, there is always some water standing in the middle of both beams, about 1cm (0.4 inches) deep. The roof has been installed for 2 weeks.
Does anyone have experience with this? Thank you.

Well, if the roofing has only been in place for 2 weeks, I would definitely communicate with KD about it and not rely solely on statements here in the forum. My gut feeling says it’s probably not a concern, but since there is water standing there, I would clarify this with the supplier to avoid potentially risking any warranties.

Is water present at the junction of the two crossbeams, that is, at the middle post? In my case, an aluminum plate was screwed in there and then sealed with sealing compound. This means the area is higher than the rest, so water tends to collect on one side.

The joint is positioned slightly higher. The water level is between the two crossbeams.

In any case, report the issue and describe your observation.
Can you upload pictures related to this?

Water should definitely not be standing on it.
