A building may combine steep-slope and low-slope coverings or different material systems. Replacement planning should identify which sections are included and how their junctions will be handled. Treating the roof as one uniform material can obscure scope gaps.
What to do next
Request a marked plan and a specification for each area. Ask how new and retained systems connect. Keep warranties and maintenance instructions organized by section so future service uses the correct approach at every location.
