Overview
Find the source, not just the symptom.
Water is a patient traveller — the stain on your ceiling is rarely under the actual leak. ONTRA uses a forensic combination of thermal imaging, controlled hose testing, tracer dye and moisture meters to locate the true point of entry, then documents the pathway from roof to ceiling with photos and a written report. We don't guess, we don't sell you a roof you don't need, and we don't leave until the leak is proven dry. It is the difference between fixing a leak and paying someone to try.
Every roof leak detection 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.
