At a glance: John Beal Roofing replaced the roof on Green Haven Drive in St. Peters, MO 63376, finishing October 27, 2026. 31.67 squares of GAF Timberline HDZ, installed over synthetic underlayment across the full deck. Handled by our St. Louis office (314-429-6000).
St. Peters sits in a St. Charles County city along I-70, and this house on Green Haven Drive needed a full replacement. The job wrapped up on October 27, 2026: 31.67 squares, deck to ridge. In the 63376 area, the first places a roof fails are the valleys, the eaves and the first course along the edge, so those got extra attention here.

The roofing system on this house
GAF Timberline HDZ is built around LayerLock technology and a wide StrikeZone nailing area, which makes accurate nailing much easier for the crew. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- A full layer of synthetic underlayment. It’s the backup water barrier under the shingles, and it holds up to foot traffic and wind far better than paper felt.
- Ice and water shield in the valleys and along the eaves. Those are the two places a Midwest roof takes on water first, from ice dams in January and heavy runoff in spring storms.
- Starter along every edge. The first course is where wind gets under a roof. A factory starter with its own sealant line locks it down.
- GAF Hip and Ridge cap. Pre-formed cap that seals the hips and ridge.
- Lomanco Omni Roll. It runs along the peak and lets hot, damp attic air escape, protecting the decking and keeping shingles from baking from below.
