Roof and Gutter Care for Terraced Houses
Terraced houses share walls, and often share roof lines, gutters and downpipes too. That makes roof and gutter work on a terrace a little different from a detached house. Understanding what is shared, how the roof can be reached and what to agree with neighbours makes the job go smoothly.
Shared roofs and gutters
On many terraces the roof runs continuously along the row, with only a party wall below separating each house. Gutters may also run continuously, and one downpipe can serve two houses. Moss on a neighbour's slope can wash into a shared gutter.
Knowing where your section starts and ends helps us agree exactly what is being cleaned.
Talking to neighbours
Work at the boundary may mean standing a ladder near a neighbour's property or clearing a gutter that serves both houses. Letting neighbours know in advance is courteous and avoids surprises. In some cases they may want their section done at the same time.
Where a shared downpipe is blocked, both households benefit from clearing it.
Rear access
Mid-terrace houses often have limited rear access, sometimes only through the house or via a narrow shared passage. Back additions, outriggers and kitchen extensions create extra roofs, valleys and gutters at the rear.
Tell us how the back of the house can be reached when you enquire.
Valleys and back additions
Where a rear extension meets the main roof, valleys and short gutters collect leaves and moss. These areas are often out of sight from the street and can block for years unnoticed.
Our blocked gutters page explains how blockages are cleared.
How the roof is cleaned
Moss is removed by hand, working with the tiles, and debris cleared from the roof, valleys and gutters. Where suitable, a soft wash and biocide follow. We never pressure wash roof tiles, which on a terrace could also push water towards neighbouring properties.
See our moss removal page for the method.
Older terraces and slate
Many older terraces have natural slate roofs. Slate needs careful handling because it can crack underfoot. Chimneys and party wall upstands also need attention around their flashing.
Our slate roof cleaning page explains the approach for slate.
End-of-terrace houses
End-of-terrace houses have a gable wall and often better side access, but their gutters may still connect to the neighbouring house. The exposed gable can also catch more weather.
Photographs of the gable and both roof slopes help us plan.
Front gutters over the street
Terraced houses often front directly onto a pavement. Ladders on the pavement need care for passers-by, and debris must not fall onto the path. Timing may matter on busy streets.
Mention if your house fronts directly onto a pavement or road.
Chimneys on terraces
Terraces often have shared chimney stacks on the party wall. Flashing and moss around these stacks affect both houses. Work on a shared stack is best discussed with neighbours.
Our chimney and flashing guide explains common issues.
Rear valleys between back additions
Where two neighbouring terraces have back additions side by side, a valley gutter often runs between them. These hidden gutters collect leaves and moss and can overflow into both properties.
They are often missed. Mention if your terrace has one.
Front and back can differ
On many terraces the front roof faces the street and dries well, while the back faces gardens, trees and back additions and stays damper. The rear slope often carries far more moss than the front.
Photographs of both sides help us quote accurately.

Frequently asked questions
Can you clean just my part of a terraced roof?
Yes. We agree exactly which section is included. Neighbours may choose to have theirs done at the same time.
What if the gutter is shared with my neighbour?
Debris on their side can affect yours, so it helps to agree with them. A shared downpipe benefits both houses when cleared.
How do you reach the back of a mid-terrace house?
Tell us about rear access, such as a passage or through the house, and we will plan around it.
Do I need my neighbour's permission for roof cleaning?
You do not usually need permission to clean your own roof, but tell neighbours if ladders or work will be near their property.
Can you clear the gutter between two back additions?
Tell us about access and whether your neighbour agrees, and we will look at how it can be reached safely.
Is it cheaper to do the whole terrace at once?
Neighbours sometimes choose to book together. Each house is quoted for its own section so the scope is clear.
