About This Service
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.
Distinguish component repair from a rebuild
Localized damage does not automatically require rebuilding an entire chimney. Conversely, a cosmetic patch is not a substitute for a broader repair when the condition calls for it. We explain the extent of the proposed work and the findings that support it.
Keep recurring symptoms documented
A short account of when moisture returned after earlier work can be useful. Record the observation without exposing yourself to roof access or reproducing unsafe conditions. This history helps distinguish a recurring complaint from a new symptom at a different location.
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.
Describe the Replacement Metal
When a cap or cover is replaced, material and configuration belong in the proposal along with removal and attachment. A photograph of a similarly shaped product is not a full specification. Ask which component is being supplied and whether any supporting work is required before it is fitted.
