Process & Materials

Our Replacement Standard

A new roof is a significant investment. We handle the entire process with structured workflows to minimize disruption.

1. Comprehensive Assessment

We evaluate the roof decking, structural integrity, and ventilation systems before ordering materials.

2. Full Tear-Off

We completely remove the old roofing material down to the wood deck to identify and repair any hidden dry rot.

3. Deck Preparation

Structural repairs and GAF leak barriers are installed at valleys, eaves, and penetrations.

4. Precision Installation

Installation of high-grade GAF shingles or low-slope membranes by certified crews.

Confirmed Materials

We use verified GAF components to ensure your system qualifies for complete warranty backing.

  • GAF Presidential Asphalt Shingles (premium sloped roofs)
  • GAF Standard Timberline Shingles
  • GAF TPO Single-Ply Membranes (flat and low-slope roofs)
  • GAF Cobra Attic Ventilation systems
  • GAF WeatherWatch Leak Barriers

Frequently Asked Questions

Do you install new shingles over old ones?

No. We perform a complete tear-off. Overlaying new shingles over old ones hides structural rot and voids most manufacturer warranties.

How long does a typical replacement take?

A single-family residential roof replacement usually takes 2 to 5 days. Larger HOA or commercial projects can span several weeks or months depending on the number of buildings.

Why The Badge Matters

A credential fewer than 2% of contractors hold

GAF invites a select group of roofing contractors in North America to become GAF Master Elite® Contractors. It isn't awarded for volume — it reflects a track record GAF is willing to stand behind with its own warranty.

That backing means qualifying roofs installed by ABC Builders Group can carry enhanced, manufacturer-issued warranty coverage — not just a contractor's workmanship guarantee.

  • GAF Golden Pledge® Limited Warranty on qualifying systems
  • GAF Silver Pledge™ Limited Warranty on qualifying systems
  • GAF System Plus Limited Warranty on qualifying systems
