Choosing the Right Repair for the Roof Type
Water landing on a terrace roof does not know where your title deeds stop. It runs down the slope, and if it gets under the covering it runs along the battens too. A defect two houses along can put water into your bedroom, and it will keep doing it however many times somebody repairs the slope directly above your ceiling.
The party wall is the usual culprit. Where a party wall rises through the roof it is weathered with lead, and where it stops short of the surface the covering simply passes over it. Either detail can fail, and when it does the water arrives on whichever side of the wall the slope happens to fall.
The second is the shared valley or box gutter, which on some Crewe terraces runs behind a parapet at the front. It carries the water off several roofs, it is out of sight from the street, and it is the single most common cause of a long-running leak we are asked to solve after somebody else has had a go.
The third is access. Working on a mid-terrace roof often means getting to it over or past a neighbour’s property, and scaffolding a terrace is a different job from scaffolding a semi. That is not a reason not to do the work; it is a reason the quotation may look different from the one your friend with a detached house got, and we would rather explain that up front than have it look like an inflated price.
If we find the source is next door, we will tell you plainly, and we will put it in writing so you have something to show your neighbour. That conversation is easier with a roofer’s written assessment than without one. We cannot go onto a neighbour’s roof without their permission, and we will not pretend otherwise.
Slate, Nails and the Age of Crewe’s Roofs
Most of the original Crewe terrace roofs were natural slate, and most have been partially reslated at least once. That produces roofs that are a patchwork of ages, where a slope may have thirty-year-old slates next to hundred-year-old ones.
The failure mode is almost always the nails. Slate itself lasts far longer than the iron or steel that held it up, so slates start slipping in ones and twos with nothing to blame it on. A slope that has had a dozen slates refixed over a decade is a slope telling you its fixings have gone generally.
A lot of Crewe terraces have also gained a rear extension with a flat or shallow lean-to roof at some point. The junction where that roof meets the main house wall is the other place we spend a lot of time.
Repair or Replace in Crewe?
On a terrace the repair-or-replace decision is rarely just yours, which is the awkward part. Reslating your section of a continuous slope is perfectly possible, and we do it, but the new work then abuts old work at each end and those junctions have to be detailed properly rather than simply butted up.
Where the whole run is at the same stage, neighbours co-ordinating the work is genuinely cheaper and produces a better roof, for the same access reasons as anywhere else. Where it is only your section that has gone, we will do your section and detail the joins so they are not the next problem.
Storm Damage & Emergency Roof Repairs in Crewe
On a terrace, storm damage is everybody’s problem and nobody’s. Wind gets the most leverage at the ridge and at the top course of slates, and a slate dislodged four doors down can put water into your roof space rather than theirs.
If slates have come off into the street, the priority is making the roof safe before anything else — a partly dislodged slate above a pavement is a hazard to people walking past, not only to the house.
Emergency call-outs run 24 hours a day, Monday to Friday, with
Saturday and Sunday cover from 8:00 to 19:00.
Please do not go up to look. More people are
hurt inspecting storm damage than by the storm itself. Call
