A Timberline HDZ shingle roof installation in St. Louis

What the signed proposal included

• GAF Timberline HDZ asphalt shingles
• GAF Seal-A-Ridge ridge shingles
• GAF FeltBuster synthetic underlayment and Pro-Start starter

Roof details and scope

The signed proposal selects the HDZ shingle package and identifies ridge shingles, synthetic underlayment, and starter as separate components. The selection provides a specific material basis for this case. Alternative packages in the proposal are not treated as products installed on the roof.

The construction photograph looks across a gray shingle plane toward the far end of the roof. Some materials remain visible there, making it a record of installation rather than a final cleanup image. The photograph is presented at its original modest resolution; it supports a view of the shingle field without implying a detailed inspection of every roof connection.

This project is also a useful example of keeping separate exterior proposals distinct. A roof contract and a separate soffit or fascia proposal should each identify the work that was accepted. For a similar replacement, confirm which roof-edge items belong to the roofing scope and which require their own authorization, access arrangements, and completion record.

Project completion

The installed shingle field was photographed on June 11, 2026. The project reached its job-complete stage on June 12. The case describes the selected roofing materials and the visible installation. It does not add separately proposed exterior work to the completed scope or infer concealed underlayment details from the finished shingles.
