Damp creeping down a back-bedroom wall after a wet week? Peak Roofing is a roofing company based in Lancashire, covering Accrington, Oswaldtwistle and Great Harwood. More than half of Accrington’s homes are terraced and more than half were built before 1919, so we start where old terraces let water in: the gutter along the row, the valleys and the chimney stack.
What goes wrong on Accrington roofs
On a terraced street the gutter is one long run shared by every house, and 55% of Accrington’s homes are terraced. When a section sags or a joint opens, the water spills down the front or back wall, and from inside it looks as if the roof is leaking. A blockage two doors along can back water up past your house as well. So we check the fall and every joint along the run, not just the stretch over your window, and renew the fascia board behind it where the timber has rotted.
Valleys come next. Where two slopes meet, the water off both runs down one lined channel, and on old slate roofs that lining is often tired lead or felt. With 43% of homes here built before 1900, a lot of valleys have done a very long shift. Once the lining has split or slipped, rain gets under it every time the channel runs full, and the first sign is usually a stain in the corner of a back bedroom.
Very little has been built since: only 16% of homes date from 1983 on. Most Accrington roofs have had decades of repairs, some good and some not, from bitumen painted over slates to odd tiles pushed into a slate slope. We tell you which old repairs are still doing their job and which are holding water in. A back extension with a felt flat roof gets its own check, especially where the felt turns up against the house wall.
Roof repairs in Accrington: what we check first
- Gutters along the row An overflowing gutter on a terrace soaks the front wall and shows as damp along the bedroom ceiling.
- Valley linings Where two slopes meet, constant wet and moss can push water over worn lead or felt.
- Stack pointing and pots Mortar washed out of an old stack lets rain into the chimney breast, sometimes in two houses at once.
- Rear flat roof joints Where a felt roof meets the back wall, the upstand often cracks first and lets water behind it.
A roof that rarely dries out
Accrington sits on the wet side of Lancashire, and for a roof what matters is less how much rain falls than how often. Wet days come in every month, so a slate roof seldom gets a dry week, and the shaded slopes and valleys stay damp for most of the year.
Damp slate grows moss, moss holds more water, and in a valley it acts like a small dam that pushes rain sideways over the edge of the lining. Old stacks suffer as well: steady rain washes the mortar out of their joints a little at a time, until water starts finding its way into the chimney breast.
Listed homes and conservation areas in Accrington
Hyndburn Borough Council looks after ten conservation areas. In Accrington they are Accrington Town Centre and Christ Church; Oswaldtwistle has Rhyddings, The Straits and Stanhill, and Great Harwood has its own area plus Tottleworth. Like-for-like repairs are usually fine in all of them. Listed houses add another layer: a Grade II town house of about 1860 on Cannon Street still keeps its hipped slate roof. If your home is listed, or in one of those areas, ask Hyndburn’s planning team before slate is swapped for anything else.

Questions
Accrington roofs: questions
Can you re-roof just my house in an Accrington terrace?
Usually, yes. The new roof is finished against the party wall so it meets next door’s slates properly. It’s worth telling your neighbours first, as scaffolding and noise affect them too. See re-roofing.
Why is there a damp stripe along the top of my bedroom wall?
That line often points to the eaves. A sagging or blocked gutter, or a rotten fascia board behind it, lets rain spill down the wall instead of into the downpipe. Replacing the run in uPVC is a common fix. See guttering and fascias.
There’s thick moss in the valley at the back. Is it doing any harm?
It can be. Moss holds water and slows it down exactly where it should run off, so in a worn valley it can push rain over the edge of the lining. Clearing it shows what state the lining is in, and a split one is relined rather than patched. See roof repairs.
