A well-kept roof. The slate covering is sound and even, the ridge is true, the chimney flashing is properly dressed and the lead valleys are clean and running. Nothing here needs doing today. The single item worth noting is a small patch of moss starting in the foot of one valley — five minutes' attention now keeps it from becoming a job later. We'd be comfortable telling a buyer this roof has been looked after.

Five items recorded. Four are in good order and noted as a record of condition; one is a minor maintenance item to keep on top of.
The ridge tiles are sitting true and evenly, with the bedding mortar intact and no lifting or gaps along the run. The ridge is the most wind-exposed line on a roof, so a sound ridge is a good sign the roof has been maintained.
Recommended: no action. Recorded as a benchmark of condition.
The lead flashing and soakers around the stack are properly dressed and sitting tight to the brickwork, with no lifting or temporary repairs. This is the joint most roofs fail at first, so finding it in good order here is worth recording.
Recommended: no action. Re-check at the next survey.
The valleys are lead-lined, clean and running freely, with the slates cut neatly to them. Valleys carry the most water on a roof of this shape, so clear, sound valleys are exactly what you want to see.
Recommended: no action beyond keeping them clear — see finding 5.
The slates are even and well-laid across both slopes, with no slipped, cracked or missing units visible from the air and only normal surface weathering for the roof's age. No delamination or widespread nail-sickness apparent.
Recommended: no action. Normal weathering only.
A small patch of moss is establishing in the foot of one valley, near the gutter. It is harmless today, but moss in a valley traps debris and water over time and a valley is the one place you don't want water held up. This is the only item on the roof worth doing anything about.
Recommended: remove the moss by hand and keep the valley and gutter clear. A look once a year keeps a roof like this in this condition.
This is an external visual inspection carried out by drone. It records the visible condition of the roof covering, ridge, chimney, flashings, valleys and rainwater detail from the air on the date of survey. It is not a structural survey, a RICS Home Survey, or a guarantee of watertightness, and it does not assess anything not visible from above — roof timbers, the underlay, insulation, internal leaks, or anything beneath the covering. Findings and gradings are the surveyor's professional opinion from the imagery and are intended to give you a clear record of condition and help you prioritise any maintenance; they are not a quote for works. This sample uses illustrative imagery and does not relate to a real property.
