Islington is known for its Georgian and early-Victorian terraces in London stock brick, many arranged around garden squares, plus later Victorian streets towards Holloway. We carry out roofing across Islington (N1 and N7), including homes on and around Canonbury Square and Gibson Square.
Islington’s Georgian terraces typically have a butterfly roof behind a parapet; keeping the central valley gutter and its outlet clear is key to stopping leaks. A large share of the borough lies in conservation areas, where the council expects traditional materials.
We start with a roof survey, take photos of what we find and give you a clear written quote before any work begins. We are based in Hackney E9, so Islington is on our doorstep.
Do you replace flat roofs on rear extensions in N1 and N7?
Yes. We replace felt and failed flat roofs with GRP fibreglass or new felt systems on extensions, dormers and back additions across N1 and N7.
Do I need permission for roof work in Islington?
Like-for-like repairs usually do not, but changing materials or roof shape may. A large share of the borough lies in conservation areas, where the council expects traditional materials. We can advise before work starts.
Can you match the original slates or tiles in Islington?
Yes. We source reclaimed or new natural slate and clay tiles to match, which matters in conservation areas such as those in Islington.
Islington’s Georgian and early Victorian terraces often have “butterfly” or valley roofs hidden behind a front parapet wall. From the street the roof is invisible, which is why small problems in the central valley gutter or around the parapet can go unnoticed until water comes through a top-floor ceiling.
What we usually find: blocked or split lead valley gutters, slipped Welsh slates on the two pitches, cracked render and failed flashings on parapet walls, and worn chimney stacks shared with the house next door. Rear extensions and dormers added over the years often have flat roofs that need repair or replacement.
Before work starts: much of Islington is covered by conservation areas, including Barnsbury, Canonbury and Highbury. Like-for-like repairs in natural slate and lead do not usually need planning permission, but changes to materials or roof shape can. We advise on this during the free survey and include access, such as scaffolding and any council licences, in the written quote.
We also carry out roofing in nearby Highbury, Archway, Camden and Hackney.

“We’re so pleased to have had Lee, David, and the whole BARL team complete significant repointing, drainage, and roofing works on our building of flats. From diagnosing the issues to completing the work they were extremely diligent, communicative, and professional. The quality and finish of the work speaks for itself and we wouldn’t hesitate to recommend them or use them on future projects.”
“Had serious water ingress and after multiple amateur roofers trying to solve the problem I decided to go with a proper outfit. David and his team were very professional and sorted out the issue within a week in the hottest weather of the year. Definitely recommend”
“We recently had a new slate roof installed and it was a really positive experience. The team were professional, turned up when they said they would, and kept things tidy throughout the job, which we appreciated. David and Lee explained everything clearly at the start, so we knew what to expect in terms of timing and cost. All our questions were answered quickly. Highly recommended if you need a new roof in North London!”
“Excellent service from start to finish. After a previous roofer failed to fix the issue, Barl quickly identified the root cause and resolved the leak by replacing my gully and carrying out additional repairs. Their communication was clear and thorough throughout, with different options presented along with the pros, cons and costs of each. They were punctual, professional, left everything clean and tidy, and were friendly and courteous at all times. I would highly recommend David and the entire Barl team.”
“We recently had our chimneys, roof and guttering redone by BARL, they were absolutely fantastic and surpassed our expectations. Lee, David, Tommy, Jim, Enrik, Adrian and Peter were reliable, knowledgeable, considerate and above all kept us informed and explained everything the did throughout the whole process. We've got a little baby and they even stopped work to allow us to put her to bed regularly. We'll be recommending them to everyone.”
“There are possibly cheaper ways to stop your house falling down, but I doubt there are better. The crew on site went out of their way to be diligent, tidy and respectful, which made living and working through a major works project so, so much easier than I had feared or expected. If you have an old London house falling down and the roof falling off, Barl are a good choice of people to call.”
“I'm extremely pleased with the new roof installation BARL did for my home, and I'm beyond impressed with the entire process. From the initial Assessment to the final touches, their professionalism and expertise were clear. David and the guys were respectful of my property and they worked efficiently without causing any disruption. The whole experience was smooth, and I will definitely use them again for future projects!”
“BARL has installed a GRP fibreglass roof + GRP-capped fibreglass parapet walls, and the transformation is remarkable. The process was smooth and efficient. This investment was worth it and the BARL team is very competent. I was managing the project from abroad but all was fine. Their professionalism extended to interacting with my tenants, ensuring minimal disruption and accommodating their schedules. I will recommend them.”
“We recently had BARL install a new slate roof on our home, and once again, they exceeded our expectations. This was our second time working with them—the first being when they repointed our brickwork—and their consistent professionalism and expertise continue to impress us. From the initial site visit to the final inspection, David and his team were thorough, knowledgeable, and attentive to our needs. They patiently answered all our questions and guided us in selecting the best materials for our home. The team maintained a clean work environment, tidying up after each day's work, and the quality of their craftsmanship is outstanding. We highly recommend BARL to anyone seeking reliable and high-quality roofing services.”
