Director of Training & Quality Control
On staff, not an outsourced function, setting the standard our crews install to.
Specialists on demand
Storm-damage inspectors, public adjusters and engineers, brought in when a project needs them. You never manage the handoff.
What we stand for
Five principles, on every project.
The standard we hold our crews, our specialists and ourselves to.
Workmanship is the warranty.
“Manufacturers cover materials. We cover the work. If we installed it, we own it.”
One contractor, accountable.
We coordinate the specialists, adjusters, engineers and suppliers. You never manage the handoff.
Straight answers, every time.
If a repair will outperform a replacement, we say so — even when it means a smaller job.
Permanent results.
We build to last past the warranty, not to the warranty.
Owners on every job.
If something goes wrong, you get an owner on the phone — not a message system.
Credentials
Certified where it counts.
The company credentials are GAF Master Elite® and GAF’s President’s Club Award. Individual inspection and resilience credentials belong to the owners who earned them.
