Dail-Water-Stop-Tie-In-Model.pdf

This is a technical drawing specification document for asphaltic roofing systems, specifically detailing daily waterstop and tie-in procedures for roof construction projects. The document outlines the standard procedures for creating temporary and permanent tie-ins between existing and new roof systems, with emphasis on proper material transitions and sealing methods to ensure weather-tight connections during multi-day roofing installations.

The drawing specifies that before commencing work on subsequent days, contractors must remove temporary tie-in materials and insulation fillers from the previous day's work. The tie-in sheet must extend a minimum of six inches onto both existing and new surfaces, with compatible mastic used to seal all edges and reinforce the connection with mesh. The specification requires that existing insulation be properly sealed with compatible mastic before new insulation is installed, and all exposed edges must be sealed to prevent moisture infiltration. These technical requirements apply to any jurisdiction or agency undertaking asphaltic roofing system installations and serve as standard construction protocol for maintaining roof integrity during phased construction activities.
