Roof Systems

A roof system is connected construction, not a surface label. Deck, vapor control, insulation, cover board, membrane or panels, edge details and drainage all affect performance. We check attachment, seams, penetrations and repairs, then note where moisture or movement could limit a recover. A proposal assuming dry insulation without evidence can leave a new surface above old wet material. Selective openings or a moisture survey can distinguish retained layers from material needing removal. The inspection may direct comparison toward built-up construction, modified bitumen or single-ply membrane.

Metal panels expand and contract as temperatures change. Clips, sidelaps, end laps, penetrations and transitions must allow movement without opening a water path. Retrofit metal can cover an existing roof only when framing and load conditions support the design and drainage remains workable. The scope accounts for panel length, clip placement, perimeters and equipment supports. We inspect framing information and existing layers before recommending an overlay. For a current metal roof, a standing-seam review may identify seam, fastener or flashing repairs before panel replacement is considered.

Centennial commercial reroof submittals request manufacturer specifications for fastening methods and installation standards, plus a plot plan showing work areas. A mid-roof inspection is a scheduled checkpoint before concealed work proceeds. We build those requirements into the estimate and identify what must stay visible before close-in. Owners should compare assemblies by more than material name: include preparation, insulation, attachment, perimeter details, penetrations, drainage and access for later maintenance. A roof inspection and replacement scope make the comparison practical.
