My microwave vents to the roof and leaks during heavy rain. How do I fix it
We have a sloped roof and the vent is close to a valley. We went up and installed taller flashing and roofing tar to seal under the new flashing and thought we had diverted the water that comes down the valley. Apparently not! I do have the manufacturer of my modular looking into it. But since they were the ones who last worked on it I am sceptical of their abilities and this is why I am trying to get more info.
Maybe I need to get a qualified roofer out for a look.
