Commercial roof inspections, explained

How a school roof is inspected, and when it can be done

A school roof is usually several roofs of different ages joined together, over rooms that cannot be closed during term and over equipment nobody wants rained on. The inspection is built around the calendar as much as around the roof.

A school roof inspection is a condition survey of every roof area on the site, carried out so the findings arrive in time to be repaired in a school holiday. That timing requirement is what makes it different from any other commercial inspection.

The second difference is that a school is rarely one roof. A typical site has an original block, two or three extensions, a hall, a sports building and a set of temporary classrooms, each with a different system, a different age and a different person who last worked on it. An inspection that produces a single verdict for the site has thrown away the only information worth having.

Divide the site before you walk it

Number every roof area on a site plan and inspect against those numbers. A flat roof over the hall, a pitched roof over the original block and a membrane over the new science wing are three different assets with three different remaining lives, and the money should follow the worst of them rather than the average.

For each area the report should record the system, the approximate age, the condition, the defects found and what each one needs. Our page on how to read a roof inspection report sets out what makes that document usable rather than merely descriptive.

What gets looked at

Area What the inspection is checking
Membrane or covering Splits, blisters, open laps, slipped tiles, exposed felt
Outlets and gutters Blockage, ponding, overflow provision, water staining below
Rooflights Cracking, crazing, failed kerb flashings, fixings through the glazing
Plant and equipment Flashings at curbs, condensate runs, feet bearing on the membrane
Perimeters Edge trim, copings, parapet details, flashings at abutments
Junctions between blocks Movement joints, open details where two roofs meet
Cable and pipe runs Penetrations added later, fixings driven through the waterproofing
Inside Ceiling staining, loft spaces, plant rooms, corridor ceilings

The internal part matters more on a school than on most buildings, because a leak over a corridor or a sports hall ceiling shows up as a stain weeks before anybody sees water, and the stain is often the only clue to which roof area is failing.

Access is planned, not improvised

Roof access on a school site is frequently the limiting factor. Some roofs have a permanent ladder and a hatch, some need a tower or a hoist, and some can only be examined from a neighboring roof or by drone. Settle which applies to each numbered area before the day, because an inspection that reaches six of nine roofs has produced a partial answer and should say so in writing.

Where the roof cannot be reached safely, a drone roof inspection will record the surface and the details without anybody going up, and it is often the fastest way to cover a steep or fragile area over an occupied room.

Turning findings into a holiday program

  1. Split urgent from planned. Anything letting water in now needs pricing immediately, not at the next budget round.
  2. Group the work by roof area. One visit to one roof costs less than three.
  3. Price the access once. Scaffold or a hoist is often the largest single line, and it covers everything done while it is up.
  4. Decide repair or renewal per area. A roof with widespread failure is not a repair job, and spending on patches delays the inevitable.
  5. Book the work before the term ends. The holiday weeks are bid for by every school in the district at the same time.

Keep the record

The value of a school roof inspection compounds. The second report is worth more than the first because it can be compared, and the fifth turns into a renewal program the district can fund in sequence rather than in emergencies. Keep the site plan, the photographs and the ratings in the same place each year.

If the roofs on a campus have never been surveyed as a set, the commercial roof inspection checklist is the place to start, and a prepared visit with access arranged and drawings to hand returns far more than an unannounced one.

Common questions

When in the year should a school roof be inspected?

Twice if the budget allows, and the two visits do different jobs. A spring or early summer visit finds the winter damage while there is still time to repair it in the holiday, and a late summer visit confirms the roof is ready before the building fills up again.

  • The repair window and the holiday window are the same weeks
  • A spring visit feeds the figures into the next budget round
  • A late summer visit catches work done badly over the break
  • A visit straight after a storm sits outside the cycle
  • Reinspection after any roof work is worth asking for

Timing is what separates a school roof program from a commercial one. Almost all roof work on a school happens in a few weeks when the building is empty, so the inspection has to land early enough for the findings to be priced, approved and procured before those weeks arrive. An inspection in October usually means waiting until the following summer, which turns a small repair into a year of water getting in.

Can a school roof be inspected while pupils are in the building?

Yes, and most are. Looking at a roof needs no power down, no evacuation and no noise, so a condition walk can happen on a normal school day. What changes is the access route, the supervision and the paperwork rather than the inspection itself.

  • Roof access through an occupied corridor needs escorting
  • Background checks are a district requirement, not a roofing one
  • External ladder or hoist access avoids the building entirely
  • Internal checks of ceilings need to follow the timetable
  • Anything dropped from height needs the ground area closed

Agree the route and the hours before the day rather than at the gate. Where access is through a plant room or a hatch in a classroom ceiling, that part is often better done in the first or last hour, and where a lift or a tower is needed the area below has to be fenced, which usually means outside school hours. Ask what identification and clearance the inspector will need, because turning one away at reception wastes a visit.

Who in a school district should receive the roof report?

Whoever holds the maintenance budget and whoever holds the capital budget, because a roof report normally contains work for both. Sending it only to the site manager is the commonest reason findings stall, since the items that matter most are rarely inside a site budget.

  • The facilities or estates lead, for the repair items
  • The finance or business manager, for the capital items
  • The insurance contact, where storm damage is recorded
  • The site manager, who will see the problem first next time
  • The file itself, so next year's report has something to compare

Ask for the report in a form that splits the two. Urgent and routine repairs in one list with the information needed to get them priced, and renewal or replacement items in another with an indication of the years involved. That way the same document serves a work order and a budget submission without anybody having to rewrite it, and nothing falls between the two budgets, which is where school roofs usually fail.

How is a campus with several roofs inspected consistently?

By numbering the roofs before anybody walks them and reporting against those numbers every time. A campus is not one roof, and treating it as one produces an average condition that describes nothing and tells the district nothing about where to spend first.

  • Number every roof area on a site plan and keep the numbers
  • Record the system, the age and the condition area by area
  • Use one rating scale across every building on the site
  • Photograph from the same positions year to year
  • Rank the areas rather than scoring the campus

The plan with the numbers on it is the asset that outlasts any single report. Once it exists, each year adds a column rather than starting again, a new inspector can pick the work up without reinventing the scheme, and a roof that is deteriorating faster than its neighbours becomes visible in the comparison rather than in somebody's memory. Keep it as a drawing, not as a list of building names.

What does a school roof inspection find most often?

Blocked outlets, failed rooflight details and damage around equipment installed after the roof was built. All three come from the same cause, which is a roof that has been added to over decades by people who were not thinking about the waterproofing.

  • Outlets and gutters blocked with leaves, balls and litter
  • Rooflights crazed, cracked or flashed with sealant alone
  • Cables and pipes run across the roof and fixed through it
  • Patches over patches where a leak was chased, not found
  • Open joints where an extension meets the original building

The junction between an older block and a newer one is worth the inspector's time more than any open field of membrane. It is where two systems of different ages meet, where the movement is, and where the original drainage was usually interrupted. On most school sites the recurring leak everybody knows about is at one of those joints, and it has been patched rather than detailed.
