What this means for your clause

Roofing subcontracts and reroofing allowance clauses in a building contract name this series rather than the paving asphalt index, since shingle and roofing felt manufacturing carries its own asphalt grade and coating cost that paving mixture pricing does not reflect.

Draft a clause

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.

The [affected portion] of the Contract Price shall be adjusted using US PPI — Asphalt Shingle and Coating Materials Manufacturing, Prepared Asphalt and Tar Roofing and Siding Products (BLS series PCU3241223241222), published by BLS.

Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value.

Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value.

Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement.

[Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
