The step flashing sits under the roof shingles along the brick part of the chimney while the counter flashing covers the step flashing and is embedded into the brick. If the slope is less than 3 12 you ve likely found the source of the leak. Actually when a standing seam metal roof has a leak it is commonly at some type of flashing area. Failed sealant or butyl tape sealants and butyl tape are used to seal out water dirt and other debris that could compromise a metal roof.

These two l shaped chunks of metal work together to form an impenetrable seal around where your chimney meets the roof. This is not likely the problem though since very little water could enter the walls of the chimney and since the chimney comes in sections it is hard for water to leak from one section to the next. Cover the chimney bricks while leaving the flashings around the very base of the chimney exposed. If the metal chimney is rusted or damaged above the roof rain may be able to enter the space between the walls of the chimney.

For tile roofs the underlayment which keeps water out may be deteriorated. Contractors will inspect the metal roof s surface.
