Preventative Maintenance

Overview

Plans that prevent the call you don't want to make.

Preventative maintenance is the smallest annual spend that prevents the largest possible loss. A single blocked box gutter can flood a home; a lifted flashing can rot a ceiling frame for years before anyone notices. ONTRA's preventative plans include a scheduled annual inspection, a written photo report of every defect, priority access when things go wrong, and an automatic extension of your original workmanship warranty. It is the plan we put on every roof we install — and the plan we wish more roofs had.

Every preventative maintenance project at ONTRA follows the same process: site inspection, written scope, fixed-price quote, fabricated and installed by our in-house team, and signed off with a final photo report.
