Hello,
we would like to install our satellite system on our roof, which has a 5° slope. The cables will not pass through the roof to avoid any potential weak points (they will be laid externally). However, our construction management is rejecting the installation of a mounting base where concrete slabs can be placed. They say the slabs would be too heavy for the roof. I find that hard to believe. Could the mounting base possibly shift due to wind?
Are the concrete slabs really a problem for a single-pitch roof?
All our neighbors have their satellite dishes on their single-pitch roofs. Strange, isn’t it?

That doesn’t make sense. We don’t even know his preferences. Maybe it needs to be 120cm (47 inches), or perhaps 50 or 60cm (20 or 24 inches) would be enough.
@TE
How are we supposed to know which basin or what height you need?
Both are relevant to discuss the weight. The same applies to the site managers as well.
Without knowing the weight, no statement can be made, except that the roof is generally designed with very tight margins. However, that would always exclude additional photovoltaic or solar installations.

Sebastian793 Jul 2016 11:32This is not nonsense – this is my recommendation. He asked for it... no need to react so strongly right away.
I assume HD and Astra as the standard, and you should install at least an 80cm (31.5 inches) dish to avoid problems in bad weather.
And before someone smart-alecky says they have no issues with a 60cm (23.6 inches) dish: of course that can work – it always depends on the circumstances. But with an 80cm (31.5 inches) dish, you won’t go wrong and can avoid potentially costly trial and error.

toxicmolotof3 Jul 2016 12:45But for HD and Astra, in good old Germany you usually don’t need an 80cm (31.5 inch) dish, not even in bad weather or with a bit of snow.
With an 80cm (31.5 inch) dish, you can still barely receive Astra at 28.8° in the middle of Germany even during 90% of all thunderstorms.
The problem with an 80cm (31.5 inch) dish is that you need at least a 100cm (39.4 inch) mast, which in turn requires at least eight 40x40x4 mm (1.6x1.6x0.16 inch) plates for a secure base, meaning about 120 kg (265 lbs) spread over roughly 0.64 m² (6.9 ft²).
For our mounting bracket, we chose 50x50x5 mm (2x2x0.2 inch), which corresponds to 230 kg (507 lbs) per square meter.
Not every flat roof can support that.
