So, I am about to install some new parapet flashing in a new personal retrofit project.
The contractor has suggested a specific model. However, I find the drip edge to the external side of the building too close to the wall.
My question is: What is the minimum recommended distance between the drip edge of the flashing and the wall to guarantee that the water drips away from the building?
I acknowledge that this distance may depend on the height of the wall, rainfall or wind, but I wondered if there is any general guidance.
Many thanks in advance,
