J&M Roofing Shingle & Vent Replacement. Ceiling Knockdown Water Stain Repair

J & M Roofing did my roof. Corporate/Legal Name J&M Residential Services LLC. License Number CCC1331951. Check reviews before hiring the wrong company like I did! This is just one of the many issues I had with J&M Roofing. They blamed it on wind driven rain but it leaked every time. Vent was replaced and does not leak anymore even in heavy "wind driven" rain and they refused to fix the water damage.

This is my first knockdown amateur repair. I watched videos like you're doing in order to try it. I hope this helps.
