About This Service
Distinguish cap from crown
A cap and the masonry crown are different chimney-top components. A missing cap does not establish that every leak originates at the opening, and a cracked crown needs its own assessment. The repair scope should name the part being corrected and explain its relationship to the reported concern.
Assess the roof junction
The connection between chimney and roof includes details that manage water at the intersection. BIA describes base flashing and counterflashing as related components. The proposed repair should address the relevant connection rather than assume a surface bead of sealant resolves every junction problem.
Separate old stains from active entry
Discoloration can remain after a past event. Tell us whether it is changing and what has already been repaired. The assessment should not use an old mark alone as evidence that the same water path remains active or that the previous work has failed.
Discuss finish matching before work
Replacement masonry or repaired surfaces may not look identical to weathered adjoining materials. Discuss appearance as well as function when reviewing the work. The proposed finish should be clear without presenting a visual match as proof that the water-management detail has been corrected.
Assess Openings in Metal Components
A damaged cover or earlier attachment can leave details that deserve assessment. The proposed work should identify whether the metal component, its attachment or adjoining material needs correction. Choosing another fastener or adding sealant without evaluating the installed arrangement should not be presented as a complete repair plan.
