The Inspection-First JDH Process
JDH does not lead with a sales pitch. We lead with a forensic inspection. Here is how a project moves from first call to final walkthrough.
Forensic Inspection
A HAAG Master Certified specialist performs a 60 to 90 minute on-roof audit, including the attic, ventilation, and decking.
PCC Method Findings
You get a written report built on the PCC Method: the Problem, the Cause, and the Consequence if it is left alone. No guesswork.
Fixed Pricing
Pricing is locked in writing before any tear-off begins, so there are no surprise change orders mid-project.
Install & Walkthrough
JDH crews complete the work and walk the finished project with you. Documented findings stay on file for future real estate inspections.
