About
A Scottsdale waterproofing company, built one roof at a time.
Imperplak Solutions was founded in 2014 by David Minarich. We started as a two-truck crew restoring TPO roofs in north Scottsdale and grew — one repeat client at a time — into a full-line commercial waterproofing contractor.

From the founder
"We're a contractor, not a sales operation."
I started Imperplak after fifteen years in the field — first as an applicator, then as a foreman, then as a superintendent for two of the bigger commercial roofing outfits in the Valley. I started this company because I wanted to run a crew the way I always thought a crew should be run: paid well, trained continuously, and held to a written scope of work the customer can actually read.
We're still a self-perform shop. Every superintendent on our payroll has at least ten years in the trade. We don't bid work we can't do well, and we don't take a job we can't staff with our own people. — David Minarich

Mission & values
Make the right call once, then document it.
Spec it right
We spec for the actual building — substrate, exposure, loads, budget — not for whatever line we want to push.
Install it right
Our own crews. OSHA-30 supervision every shift. Daily mil-thickness and adhesion QA.
Document everything
Daily photo logs, manufacturer hold-point inspections, as-built turnover packages. Every job.
