Mill Creek Commercial Flat Roof

01 Overview

Description:

On this Mill Creek commercial flat roof project we installed a new mechanically attached 60-mil IB Roof System after removing the old hot tar roofing assembly. 80-mil IB ChemGuard was installed around the grease vent system areas to protect the roof from grease contamination. Materials were hoisted to the roof using cranes and debris was lowered using scaffolding and debris chutes. Safety precautions were enforced during the project for the Pinnacle crews and all subcontractors. A non-penetrating Garlock Railguard 200 safety rail system was the primary safety system used during the project and was installed around the perimeter of the roof to eliminate fall hazards. Although the project took longer than expected due to weather that was not typical for August in the Seattle area, overall this large commercial roofing project was a great success.

Mill Creek Commercial Flat Roof Project

Pinnacle Roofing Professionals completed this Mill Creek, Washington commercial flat roof project by removing an old hot tar roofing assembly and installing a new mechanically attached 60-mil IB PVC membrane roof system. We also installed 80-mil IB ChemGuard PVC around the grease vent system areas to protect the roof from grease contamination. The project involved hoisting materials by crane, lowering debris through scaffolding and chutes, and maintaining strict safety protocols using a Garlock Railguard 200 non-penetrating perimeter safety rail system.

Project Challenges

The most difficult challenge with any re-roofing project is the weather, protection of the roof, and the safe coordination of the new roofing material in Seattle weather. The crews were faced with an unexpected rain storm the first week of the project, followed by a wind storm. Despite these issues, the building was protected throughout the re-roofing process.

Coordination and Logistics

One of the unique aspects of this project was the coordination between our workforce, the tenants occupying the space underneath, and the diverse group of supporting subcontractors, including scaffolding, stucco, and crane contractors. Cooperation from numerous tenants in the building — including dentists, restaurants, banks, and the property management team — was essential to completing the project successfully.
