Thanks to all who provide their time and expertise to this roofing forum. It is very informative.
I have a flashing question. I am getting ready for a re-roof. It has the original roof plus one on top that will be taken off down to the decking. I have an overhanging front porch. Of course it has sidewalls on each side and the porch does cover these sidewalls probably about 12"-18" out. Here is the question. Obviously these sidewalls are flashed(have no idea about the flashing method). What should be done about this area as far as flashing? Just reuse what’s there which is what the roofer indicates he will do? There has never been any known roof leak to this area. I would like to hear advice as I want to get this right and I know nothing about flashing or various flashing methods. House was built in late 60s-Southeast location.
Thanks for your help.
