Commercial roofing
Service calls and planned roof projects
Many customers first call us after a leak has returned. We trace the water path, repair the failed detail, and record what we found.
That first visit often leads to a wider look at the roof. We may find a maintenance issue that can wait, a section that belongs in next year's budget, or a system that has reached the end of its service life.
The condition of the roof sets the scope. A sound roof may need a focused repair. A worn system with broad moisture damage may need a phased replacement.

View detailsWhy Quantum
Quality you can count on
You deserve an accurate diagnosis, a schedule built around the property, and a useful record of every repair or project.
We started on the hard leaks
Quantum earned its early customers by fixing recurring leaks that other companies couldn't figure out. Those calls taught us to trace the full water path before sealing another spot.
Leadership with real time on roofs
Our founder, Anthony Avagliano, has more than 25+ years in commercial roofing. Across the rest of the team, that experience adds up to more than 50 years.
Field changes reported the same day
Roofs hide wet insulation, damaged deck, and old repairs. When we uncover one of those conditions, you hear about it that day with the available options.
Reports built for the reader
A property manager needs different records than a school business office or a general contractor. We match the photos, scope, and closeout package to the people using them.
Process
How Quantum works
Every job follows the same basic path, from the first roof visit to the final report.
Assess
Walk the property and roof, inspect the reported problem, and learn how the building operates.
Recommend
Put the findings, options, cost, and schedule in writing.
Perform
Schedule the job around the building. Settle access, notice, and staging before the crew arrives.
Document
Deliver photos, closeout records, and clear notes on the next items to watch or fund.

The company
Built on fixing problems others can't
Anthony Avagliano spent more than twenty-five years in commercial roofing before starting Quantum. The problems that shaped the company were stubborn leaks that kept returning after other contractors couldn't fix them. They called us, and we got the job done.
Those customers later called Quantum for maintenance, restoration, replacement, and construction roofing. The company grew around the needs of the buildings it already served.
We are based in West Chester, PA and serve commercial properties across the Mid-Atlantic.

Common questions
Questions we get before the first visit
What kinds of commercial properties do you work on?
Office buildings, retail centers, industrial plants, warehouses and distribution centers, schools and public buildings, apartment communities, and new commercial construction. See how we work with each.
What happens during a roof assessment?
We walk the roof, photograph what we find, and look at the details that fail first: seams, flashing, curbs, penetrations, and drains. Then you get a written summary with the problems sorted by how soon they need attention.
Can work be scheduled around tenants and building operations?
Yes. Most roofing happens while the building stays open. Before the crew arrives, we plan access, tenant notice, noise, parking, and phasing.
What documentation do you provide after a job?
Photos tied to roof areas, a description of what was done, notes on anything we recommend watching, and closeout paperwork or warranty registration where the project calls for it.
Which areas do you serve?
We are based in West Chester, PA and work commercial properties across the Mid-Atlantic. More on the service area.
Do you work on residential roofs?
This side of the business is commercial. Apartment communities and condominium associations are commercial accounts and we do handle those.
