Roof Structures
You should inspect the roof and ceiling timbers at least once a year. There should be an access panel in each ceiling to allow access into the roof space for inspections and any required repairs.
If you find any timber damaged due to termites, insect attack, or rot caused by roof leaks, take action as soon as possible.
If the damage is more extensive, then more drastic measures will need to be taken. It will be somewhat difficult to remove damaged structural timbers, such as rafters or ceiling supports, without removing the roof covering. This would also be very expensive. It might be possible to remove the roof covering just over the damaged timbers, but if not, you will need to deal with the damage exclusively.
Steel Structures
Many existing school buildings have a roof and supporting structures made of steel beams and columns.
- For safety reasons, make sure to inspect the steel structures for rust at least once a year.
- Rub down any rusty sections with carborundum paper, prime the exposed metal with metal primer, and then re-paint with two coats of gloss paint.
- Make sure you pay close attention to areas exposed to the rain, such as the ends of beams.
- Re-paint the entire steel structure every four years.
