Office Building Roofing, at a glance

Office roofs sit directly over desks, servers and paper. John Beal Roofing sequences tear-off so no occupied area is ever open, protects mechanical intakes from odor, and can run the loud work after hours. Free inspections and written scopes. Call (314) 429-6000.

What we look at on a office building roof

  • Tenant build-out penetrations flashed by other trades
  • Interior drains and overflow scuppers over leased space
  • Freight elevator and loading dock access windows
  • Protecting IT rooms and finished ceilings below the deck
How We Work It

Built Around Your Operation

Penetration audit

Every tenant build-out cut into the roof found and correctly reflashed as part of the scope.

Capital planning

Worked around lease hours

Loud work scheduled against tenant hours and building management rules, not against ours.

IT and finish protection

Work sequenced so what is under the deck, including server rooms, stays dry and dust-free.

Roofing Over Paying Tenants

On an office building the roof sits over leased space, which makes a leak a lease problem. Tenant improvements, IT rooms and finished ceilings are all downstream of the membrane.

Most of what we find traces to tenant build-outs. Every new suite adds penetrations, and when those were flashed by whoever was cheapest at the time, they are the first thing to fail. Part of the scope is auditing what has been cut into the roof and correcting it.

Access is the other constraint. Freight elevator windows, loading dock times and building-management rules decide how the material gets up, and that gets settled before mobilization.

Common Questions

Can you work after hours or on weekends?

Yes, and on multi-tenant office it is usually necessary. Off-hours work costs more in labor and we say so up front.

How do you protect what is underneath?

Only as much roof is opened as the crew can dry in that day, and we protect the spaces below, including IT rooms, before anything opens.

Do you handle the rooftop mechanical units?

We coordinate lifts and disconnects with your mechanical contractor and rebuild the curbs and flashings around every unit.

What is the lead time on a project this size?

It depends on the system, material availability and building access windows. You get a real date range at scope.

Do you offer maintenance after the install?

Yes. Twice-yearly inspections with drains cleared and penetrations rechecked, which catches the next tenant build-out before it leaks.
