Maintenance & inspections

Maintenance is the cheapest work anyone does on a roof. A blocked drain and an opened seam are both a short visit when they are noticed — and a roof replacement when they are not.

When this is needed

An inspection is worth doing twice a year: in spring after the winter, and in autumn once the leaves are down and before the snow. Also after any severe storm or hail, and before other work is done on the roof.

  • Leaves, needles or gravel are collecting around the drains.
  • Somebody has been on the roof installing equipment, aerials or solar panels.
  • Nobody knows how old the covering is or when it was last inspected.

What the work includes

  1. 01Clearing roof drains and the drainage, and checking that it runs.
  2. 02Going over seams, upstands and penetrations by eye and by hand.
  3. 03Patching small damage on the spot, while it is still patchable.
  4. 04A written summary of what was seen on the roof and what is worth doing next.

An inspection tells you the condition of the roof on that day. It is not a guarantee and not insurance — it is information you can use to time repairs yourself.

Quality of work

What decides the roof shows up close.

Good roofing work stands inspection from a few centimetres away.
