An inspection is us going up, photographing everything, and telling you plainly what needs doing now, what can wait a few years and what does not need touching at all. It is the cheapest thing we do and the one that saves the most, because almost every expensive roof problem started as a cheap one nobody could see.

Ladders, and a scaffold or pole camera where a slope cannot be reached safely. A roof cannot be assessed from the pavement with binoculars.
Every slope, every junction, the stacks, the valleys, the gutters, and the loft from inside. You end up with pictures of parts of your own house you have never seen.
The useful part is not a list of faults, it is which ones matter. We put them in order with a plain explanation of what happens if each is left.
Plenty of roofs get sold a re-roof they do not need. If yours has fifteen years left in it we will tell you so.
Photographs and notes, so you can get other quotes on the same information if you want to.
Send a photograph of the problem and you will get a straight answer on what it needs, at no cost.
No. Telling you a roof has years left is how we end up doing the work when it finally needs it, and how we get recommended in the meantime.
Yes, and it is worth doing. A surveyor will usually flag the roof as needing a specialist look, and this is that look.
Every few years on a sound roof, and after any serious storm. Gutters and valleys want clearing more often than that, especially under trees.
Yes. A lot of the useful evidence, damp timbers, daylight, torn felt, is only visible from inside.
Then you have paid for the peace of mind and a set of photographs, and we have not sold you anything you did not need.
