Common questions
Is caulk a good fix?
Only as a short-term patch. Caulk dries and cracks in a year or two. Replacing or resealing the metal flashing lasts much longer.
What does chimney flashing involve?
The roofer removes old metal and sealant around the chimney, then fits new step and counter flashing sealed into the brick. It is detail work that takes time.
Do I need a full roof?
Not usually. Flashing is a spot repair. A full roof is only needed if the shingles are also worn out or the deck is rotted.
