A new roof installation should be coordinated with the building design rather than treated as a finish applied at the end of construction.
Coordination With the Building Envelope
Roofing interfaces with walls, parapets, windows below roof lines, chimneys, mechanical penetrations, skylights, gutters, scuppers and drainage systems. Those transitions should be resolved before installation whenever possible. Sequencing matters too: the roof is central to reaching dry-in, the construction stage when the building shell first sheds water.
Steep-Slope New Roofs
For homes and other steep-slope buildings, system selection may include asphalt shingles, metal or other approved materials suited to slope, structure and architectural intent.
Low-Slope New Roofs
Commercial, multifamily and modern residential projects may use TPO, PVC, EPDM, modified bitumen or another designed roof system. Drain locations, slope to drain, penetrations and parapet detailing are critical. See low-slope roofing.
Additions and Mixed Roof Types
Additions often create difficult roof-to-wall or low-slope transitions. The new work should integrate with the existing roof and provide a clear drainage path instead of creating trapped water or inaccessible flashing.
