Commercial TPO Roof Replacement - Dallas, TX | 6,237 SF GAF System

Project Overview

This commercial roofing project demonstrates Arrington Roofing's expertise in delivering professional, energy-efficient roofing solutions for Dallas businesses. The project included complete removal of existing TPO membrane, installation of enhanced insulation layers, and a new GAF 60mil TPO roofing system.

Technical Specifications

• Total Roof Area: 6,237 SF (Flat Roof + Parapet Walls)

• Roofing Membrane: GAF 60mil TPO (Thermoplastic Polyolefin)

• Installation Method: Mechanically attached system with heat-welded seams

• Insulation: Two layers of 2.2" ISO (R-25.2 combined thermal resistance)

• Warranty: Full GAF manufacturer warranty

Project Scope

Phase 1: Roof Preparation

Our commercial roofing team carefully removed the existing TPO membrane while preserving sound insulation underneath. All debris was disposed of per Dallas city codes, maintaining a clean and safe job site throughout the project.

Phase 2: Insulation Installation

We installed two layers of 2.2" ISO insulation in a staggered pattern to eliminate thermal bridging and maximize energy performance. This R-25.2 system significantly improves the building's energy efficiency, reducing HVAC costs year-round in the Dallas heat.

Phase 3: TPO Membrane Installation

Our certified commercial roofers installed the GAF 60mil TPO membrane using mechanical attachment methods. Each seam was heat-welded to create a completely waterproof, monolithic roofing system with superior wind uplift resistance.

Phase 4: Metal Work & Finishing

Custom metal trim, flashing, and parapet caps were fabricated and installed to protect roof edges and transitions. All penetrations were properly sealed and flashed according to GAF specifications.

Why TPO for Dallas Commercial Buildings?

TPO roofing is ideal for Dallas commercial properties because:

• Heat Reflectivity: White membrane reflects Texas sun, reducing cooling costs

• Durability: Resists UV rays, ozone, and chemical exposure

• Weather Resistance: Withstands Dallas storms, hail, and temperature extremes

• Energy Efficiency: Cool roof technology meets ENERGY STAR standards

• Long Lifespan: 20-30 year life expectancy with proper maintenance

• Cost-Effective: Lower installation and maintenance costs

Project Results

The enhanced R-25.2 insulation system significantly reduces heat transfer, lowering HVAC energy consumption and operational costs. The reflective white TPO membrane further reduces cooling loads during Dallas's hot summer months. With full manufacturer warranty coverage and a 20-30 year expected lifespan, this roofing investment provides decades of reliable protection.
