Gutter Cleaning and Roof Checks: When and How

How often to clear gutters, safe ways to do it, what a roof and gutter problem looks like from the ground, and when to hire a professional in the UK.

Gutters and roofs are easy to ignore because they are out of sight, but when they fail the damage shows up inside: damp patches, peeling paint, rotten fascias and even penetrating damp through brickwork. A basic routine of looking up twice a year and clearing blockages catches most problems early.

What gutters do

Gutters collect rainwater from the roof and carry it through downpipes to a drain or soakaway. When they block, water overflows down the wall, soaks brick and pointing, and can freeze in winter. Overflows also stain render and damage fascia boards and soffits.

How often to clear them

Most houses need cleaning at least once a year, usually in late autumn once the leaves have fallen. Houses under or near trees may need twice a year, in spring and autumn. Flat roofs and valley gutters, which trap debris, may need more frequent checking.

Signs of trouble

• Water cascading over the edge in rain
• Plants or moss growing in the gutter
• Damp, green or dark staining down the wall below a joint
• Peeling paint on fascias
• Sagging sections or gaps at joints
• Water pooling at the base of downpipes
• A damp patch on an internal wall near the gutter line

The ground-level roof check

Take a pair of binoculars and walk round the property.

1. Tiles and slates: Look for slipped, cracked or missing pieces and gaps in the pattern.
2. Ridge and hip tiles: Check they are straight, and the mortar is intact.
3. Chimney: Look at the pointing, the flashing around the base and the cowl or pots.
4. Flashings: Metal or lead strips around roof edges and windows should lie flat and not be lifted.
5. Valley and flat sections: Look for debris, ponding and moss.
6. Fascias and soffits: Check for rot, peeling paint and gaps where birds or wasps could enter.

Clearing gutters safely

If you decide to do it yourself, think about safety first. Falls from ladders cause serious injuries every year.

• Use a stable ladder on firm ground, ideally with a stabiliser or a second person footing it.
• Keep three points of contact and do not overreach.
• Do not use a ladder in high wind, rain or ice.
• Consider long-reach tools or gutter vacuums that let you work from the ground.
• Wear gloves, as debris can contain sharp items and droppings.
• Bag the debris, and do not let it fall into downpipes.

After clearing, run a hose into the gutter to check it flows. If a downpipe stays blocked, push a plumber's rod or a hose in from the top, or check the gully at the bottom.

Common fixes

Do not pressure-wash a roof, as it can damage tile surfaces and push water under tiles.

When to hire a professional

Get someone in if:

• The property is three storeys or the gutters are high.
• You see roof damage, slipped slates or flashing problems.
• Fascias and soffits are rotten.
• There is moss on a large area, or a leak into the loft.

Professionals typically use ladders, towers and cameras. Gutter clearing for a standard house often costs in the region of £60 to £150, varying by region and size, while roof repairs vary widely depending on the work. Ask for photos of the problem and a written quote.

Renters and leaseholders

Landlords are generally responsible for the roof, gutters and external structure. Report problems in writing. Flats may have shared responsibility through the freeholder or management company.

A worked example: a damp patch on a bedroom wall

A homeowner notices a brown stain near the top of an external bedroom wall after heavy rain. The gutter above is full of seedlings and one joint drips. Clearing the gutter and resealing the joint stops the overflow. After a few weeks of dry weather the patch dries and does not return. Had the gutter been left, the water could have soaked into the wall for years. The sequence matters: stop the water, let it dry, then redecorate.

Seasonal checks

• Spring: look for winter damage, loose brackets and moss growth.
• Late autumn: clear leaves, check downpipes, look for blockages in gullies.
• After storms: look for slipped tiles and displaced ridge pieces from the ground.

Notes for older homes and flats

Cast iron gutters can be heavy, brittle and prone to rust, so they need gentle handling and sometimes specialist repair. Parapet and box gutters on terraces may be hard to reach and need professional access. In flats, gutters are typically a shared responsibility, so report issues to the managing agent rather than tackling them yourself.

What to tell a provider

Describe the property type, number of storeys, access, any known leaks and what you can see from the ground. Photos taken from different angles make quotes more accurate. Ask whether debris removal and downpipe checks are included, and whether a before-and-after photo is provided.

Where to find official advice

For guidance on working at height safely, see the Health and Safety Executive pages on ladders, and for wider home maintenance advice check gov.uk. If in doubt, a roofer should assess anything beyond straightforward gutter maintenance.

Frequently asked questions

Can I clean gutters from inside the house?

Not normally. You can inspect from windows and the loft, but cleaning needs external access or long-reach tools.

Do gutter guards stop me having to clear gutters?

They reduce the number of leaves that get in, but fine debris and moss can still collect. You will probably still need occasional checks.

Is it safe to clear gutters from a ladder in winter?

Avoid it in ice, rain or wind. Wait for a dry, calm day, or hire someone with the right equipment.
