An overflowing gutter is easy to notice in heavy rain. The cause is often harder to see. On Scottish roofs, the blockage may sit in a valley, behind a chimney, at a flat-roof outlet or inside a high gutter that cannot be inspected safely from a ladder.
Why drainage defects matter
Roof drainage is designed to move a large volume of water away quickly. When one route blocks, water backs up beneath coverings, spills against masonry or repeatedly soaks fascia boards. The first indoor sign may appear a long way from the original obstruction.
What can block or weaken the system
- Leaves, moss and wind-blown debris
- Fragments from cracked slate, tile or mortar
- Sagging gutters that hold standing water
- Loose joints, damaged brackets and separated downpipes
- Blocked valleys and flat-roof outlets
- Vegetation growing behind parapets or chimney stacks
Why a ground-level glance is not enough
Binoculars may show the front gutter, but they rarely reveal rear valleys, dormer channels or the upper side of a tenement roof. Aerial photographs record these areas directly and make it easier to distinguish a simple cleaning job from damaged components that need repair.
Check first, then brief the right contractor
AyeInspect does not clear gutters or carry out repairs. We provide independent photographic evidence, with visible defects circled and graded, so you can decide what work is needed and seek a fair quote from your chosen contractor.
