Wanted to contribute to the forum in the form of discussion of proper roof flashing. We just recently tackled a project where previous roofer failed to adhere to any standards for flashing. They used mostly roofing compound in place of flashing. The structure had significant siding, fascia, soffit, and deck rotting. A simple reroof took twice as long to complete due to additional steps that had to be taken. And unfortunately, there is not much out there to guide these new roofers on proper technique. I am starting this forum to share my flashing standards and to hopefully get others to share some of theirs.
Most forget to flash fascia to roof intersection. Too much rotting. This photo has fascia taken off due to severe damage. Will be replaced, which should hide most of the flashing. But also will provide protection from wind driven rain that can soak the roof soffit.
