Most of this list can be done from ground level with a pair of binoculars. None of it requires you to climb anything.
Autumn
- Clear gutters and check downpipes discharge into the gully
- Look for slipped or missing pieces after the first gales
- Check valleys for accumulated leaves
Winter
- After each storm, check the ridge line and verges from the ground
- Look for debris in the garden that has come off the roof
- Check the loft for damp or daylight during daytime
Spring
- Check for moss build-up in valleys and along tile tails
- Look at the chimney flaunching and pointing
- Check flat roof surfaces for ponding and lifted edges
Summer
- Best window for planned work — book ahead of the autumn rush
- Cut back overhanging branches
- Check fascias and soffits for soft timber or blocked vents
