Spiderman198223 Feb 2024 19:54We have a shallow 23-degree pitched roof with drainage via an eaves flashing. This means the underlay drains over the eaves flashing and everything flows over the roof tiles into the gutter. It is a cold roof.
1. How problematic is this if a photovoltaic system is installed later? Water that gets onto the underlay through the connections or roof tiles.
2. How problematic is this for the façade, since the water drips off uncontrollably? Condensation and moisture buildup, as well as snow loads in winter that pass through the roof tiles and get blown onto the façade by the wind. (2 full floors)
3. Are there any negative experiences regarding a terrace—meaning water frequently running off the eaves flashing onto the façade?
4. Should drainage generally go into the gutter starting from a certain roof size, since more water naturally accumulates?
5. Am I worrying too much?
The roof tile used has a standard roof pitch of 22 degrees.
Does the eaves flashing need to be explicitly listed in the construction and scope of work description? The general contractor just did it this way, and I would have preferred to be consulted beforehand.

The issue concerns the problems that arise with drainage using a drip edge and, if it is not specified in the scope of work, whether drainage should then necessarily be routed through the gutter during house construction.

Spiderman198225 Feb 2024 20:55If it is expected that large amounts of rainwater will need to be drained below the planned roof drainage system, the additional waterproofing measure must be drained directly into the gutter.
Are there regulations specifying when drainage into the gutter is mandatory? In other words, when can large quantities of rainwater be expected? For example, factors such as roof size, location of the house/weather conditions in the area, or specifications from the architect.
