Leaking roof flashing repair
The back porch leaks water during a particularly heavy rain storm. New
shingles were put on about a year ago by a professional roofer and it didn't leak until I hammered up ceiling boards to the inside of the porch just recently. On inspection, there is a thick bead of black caulking along the top of the flashing where it lies against the brick of the house but it must have microscopic cracks in it to cause so many leaks. If I took a heat gun and ran it along the bead of caulking along the top of the flashing, would it melt enough to seal any cracks? Or is it necessary to remove the old caulking first then apply new? Any more ideas, particularly better ones? |

Any more ideas, particularly better ones? The way I install flashing on a chimney is to chisel out some of the mortar and insert the flashing between the bricks. Then replace the mortar with that concrete repair stuff in a caulk tube. I don't find that flashing can be caulked directly to bricks and not need revisiting regularly. |
