The maintenance that saves commercial roofs is not complicated. It is a short list of checks, done on a schedule, with photos. What kills roofs is not the absence of expertise, it is the absence of anyone looking. Here is the routine worth running every spring and fall, whether you do it in-house or put it on a program.
Spring and fall, every year
Drains, scuppers, and gutters
Clear them all. This is the highest-value ten minutes on the list, because a clogged drain manufactures the ponding problems that age the roof around it. Fall matters most, after the leaves, and spring catches what winter left behind.
Seams and field membrane
Walk the seams looking for fishmouths, wrinkles, punctures, and anything you can lift with a finger. On metal, check fastener heads and panel laps. Small openings found now are caulk-and-patch work. The same openings after two winters are insulation replacement.
Flashings and penetrations
Every pipe boot, curb, wall transition, and edge metal detail. Flashings fail before field membrane on most roofs, and they fail quietly.
Around rooftop equipment
HVAC service traffic is hard on membranes. Look for dropped screws, panel dents, grease staining, and walk-path wear around every unit. If trades are on your roof regularly, walkway pads are cheap insurance.
Interior spot check
From inside, scan the deck and ceiling for new staining, especially around penetrations and along exterior walls. Interior evidence plus roof evidence together usually points to the entry point.
Not sure what your roof needs? The inspection is free and the recommendation comes before the number.
Build my maintenance planDocument everything
Photos with dates, same angles each visit. The record matters more than it seems: it establishes trends, it supports insurance claims, and it satisfies the maintenance expectations written into most manufacturer warranties. A warranty claim on an undocumented roof is a harder conversation than it needs to be.
After storms, separately from the schedule
Hail and high wind get their own walk, promptly, while damage is fresh and clearly attributable. Northern Indiana delivers both most years. Storm findings documented within days support claims in a way that discoveries months later do not.
Doing it in-house versus putting it on a program
Everything above is doable in-house with a ladder, a camera, and the discipline to keep the schedule. The discipline is the hard part, which is what a maintenance program is actually selling: the visits happen, the photos get taken, minor repairs get handled on the spot, and the documentation exists when the warranty question comes up.
