Why the written specification matters
Two quotes can use the same roof material name while allowing for different thicknesses, profiles, underlay, flashings, insulation, access and exclusions. Compare the complete proposed system.
Plan for an open roof
Replacement temporarily exposes the building. Sequencing, daily weatherproofing, forecast monitoring and protection of interiors should be explained before work starts.
