How a program works

Assess once. Plan five years. Maintain every season.

Facility teams hire us so roofs stop showing up as surprises in the budget or in the ceiling tiles.

  1. Assess

    A full survey of every roof in the portfolio, with the data you need to make decisions.

    • Drone imagery and roof plans
    • Infrared moisture scan
    • Core cuts to confirm what is under the membrane
    Output: condition index per roof
  2. Plan

    A five-year capital plan that ranks every roof by risk and spreads replacements across budget years.

    • Budget by year and building
    • Repair, restore or replace calls
    • Board-ready summary
    Output: 5-year capital plan
  3. Maintain

    Spring and fall inspections, small repairs before they become leaks, and a report after every visit.

    • Inspections twice a year
    • Drains, seams and flashing
    • Priority leak response
    Output: report after every visit

Compare maintenance programs

  • 38Msq ft of roof under maintenance
  • 4 hrP1 leak response for program clients
  • 1,900roof inspections a year
  • 97%of program clients renew

Three priorities. Written into every contract.

The dispatcher sets the priority with you on the first call. Response times count from that call, day or night.

P1 / Emergency

Water entering now

P2 / Urgent

1business day

Water stopped or caught in buckets, nothing sensitive below. Repair crew the next business day.

P3 / Scheduled

3business days

Stains and wear

Old stains, blistered seams, clogged drains. Inspected, photographed and priced before work starts.

Case studies

Big roofs, no downtime

Most of our work happens over buildings that never close. These three show how.

All case studies

"We used to find out about roof problems from the ceiling tiles. Now I get a condition score for all eleven buildings every spring and fall, and the board approves the roof budget in one meeting."
Director of Facilities / suburban school district, 11 buildings
