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.
Check the installed top assembly
The top configuration affects how a cap, cover or other component is fitted. Twin discusses the existing assembly before recommending replacement. A new part should correspond to the installed construction, rather than being selected only because its appearance resembles the old piece.
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.
Identify the requested outcome
You may need a recurring drip addressed, a damaged cover replaced or an earlier recommendation explained. Naming that goal helps frame the assessment. Twin explains what the proposed repair covers instead of bundling several unrelated concerns into a vague waterproofing package.
Discuss the handover
After the accepted work, keep the description of repaired components and any remaining recommendation. That record is more useful than a general statement that the chimney was serviced. It helps future maintenance address the correct location and installed detail.
