We have a wrap around porch and have experienced water leaking down the house siding under the porch. We just had the house reroofed and they have been back numerous times and just can not find any evidence it is from the roof. We notice in high wind/rain storms, especially from the east, there is lifting on the porch vinyl ceiling and as we have just about exhausted every other approach on trying to figure out why we get water dripping down from behind our house siding, we wonder if this is not the reason. Could this be possible? Has anyone else ever experienced this? Could it be the ceiling was installed incorrectly? As we live out in the country in a wide open area, we are wondering if the vinyl is not a good choice and should replace with a wood ceiling that will seal tight against house and be stronger against wind? Thanks for your help.
