This can be a combination of fallen leaves, moss, twigs, and other debris that can build up over time. Leaves get blown onto the roof, traveling down into the gutters. When wet, leaves can stick to gutter walls and floors, and the flow of rainwater becomes lodged in corners and downpipes.
Over time leaves will breakdown turning into a fertile compost, the perfect breeding ground for seeds, moss, and weeds that have been blown onto the roof or dropped by birds. If left unchecked, these invasive weeds can overtake your gutters, blocking the natural flow of water, plugging the downpipe leading to rainwater build-up, and possible overflow. It is critical that gutters are in good health for the winter to ensure water is free-flowing to prevent damage by snow and ice build-up.

Being part of the water loving algae family, moss (and lichen) thrives in shady, damp environments. So, properties that are north-facing or surrounded by overhanging trees, tend to receive less daylight, which prevents the roof from fully drying out. Over time, moss starts to grow in damp areas.
Have you ever wondered why moss tends to form at the edges of roof tiles? Well, as rainwater flows over the roof tiles, water cohesion, or the sticky quality, that enables waters droplets to form on your windows, causes it to cling to overlapping roof tile edges. This trapped water, unless dried out, creates a damp haven, perfect for moss formation. Where tiles are chipped, cracked, or damaged, water can permeate the surface, creating ideal conditions for moss growth.
Moss acts like a sponge, retaining water and preventing your roof from drying out. If left unchecked, damp can permeate the tiles and roof, causing possible structural damage. This is especially true during the winter months, where ice can form in moisture trapped against the tiles or masonry. When water freezes, it expands, potentially causing tiles to raise, chip or crack, leaving it vulnerable to the elements.
As a haven for insects, moss also attracts birds, who feed on and dislodge the moss, sending it tumbling into the gutters, causing potential blockages.
Yes, it can lead to costly property damage, if they are not dealt with promptly. Rainwater damage can lead to issues such as rotting fascia boards, water damage to walls, windows, ceilings, insulation, and even foundation damage. If left unchecked, water can permeate through to the internal walls, causing damp and mould spores. Regardless of whether you have cast iron, pressed steel, or plastic gutters, it is essential that these are maintained and regularly checked, to ensure water is free-flowing and clear of debris.

For a quick visual, next time it rains, get an umbrella and give your gutters a visual health check. Are they overflowing, leaking, or sagging, or is there water running down the side of the building? Any of these factors could indicate an issue with the guttering. If you have to clear your garden or driveway of falling leaves in the autumn, then it would be advisable to consider a visual health check.
For ultimate peace of mind, contact your local exterior cleaning professional, who will be able to check and help prevent expensive repairs.
