TL;DR
A workmanship warranty is the contractor's own guarantee covering defects in how the work was installed, separate from the manufacturer's warranty covering the materials themselves. The split matters when something fails: shingles that blow off from bad nailing are the installer's problem, while shingles that crack from a manufacturing defect go to the factory claim process, and manufacturers routinely deny claims rooted in installation error.
What it means
A workmanship warranty is the contractor's own guarantee covering defects in how the work was installed, separate from the manufacturer's warranty covering the materials themselves. The split matters when something fails: shingles that blow off from bad nailing are the installer's problem, while shingles that crack from a manufacturing defect go to the factory claim process, and manufacturers routinely deny claims rooted in installation error. Terms run from one year on general work to ten or more from established roofing and foundation firms, and the promise is only as durable as the company, which makes years in business part of what is actually being bought.
