Lock these non-negotiable clauses into your proposals to insulate against structural deck rot and weather backcharges.
"Base proposal excludes structural deck replacement, metal rust remediation, and rotted wood nailer replacement not visible during pre-bid visual inspection. Any deteriorated substrate discovered after existing membrane tear-off shall be invoiced via pre-agreed unit rates: 22-ga Metal B-Deck replacement at $18.50/SF, and 2x6 wood nailers at $9.20/LF."
"Installation of single-ply adhesives, hot asphalt, and polyiso insulation adhesives requires sustained ambient temperatures of 40°F (4.4°C) and rising with zero active precipitation. Delays resulting from unseasonable cold, condensation, or precipitation are non-compensable weather delays that automatically grant contract day-for-day extensions."
"Subcontractor guarantees watertight integrity only over newly installed roofing membrane and approved tie-in night seals. Subcontractor is expressly held harmless from water damage originating from un-replaced existing roofing phases, interior HVAC condensation lines, or uncapped rooftop equipment curbs."
"Roofing proposal assumes rooftop air handlers, condensers, and gas piping maintain minimum 8-inch clearance above finished membrane. All mechanical lifting, gas disconnects, electrical conduit elevation, and crane hoisting of mechanical equipment remain the sole contractual responsibility of the mechanical trade."
