Ryan and the team could not have been more helpful and professional. The quote was with me within 24 hours of visiting and the work was carried out 3 weeks later. His team was polite, friendly, and efficient taking care to protect the inside of the house while replacing our 2 large veluxes. They did a great job and cleared up afterwards so you would never known they had been. Very happy with the quality of the work and will use again if I ever need to!

Review re Harrow Roofing & Building Ltd Harrow Roofing & Building Ltd came to our rescue after some cowboy roofers put on a new flat roof on my house for me and caused more damage and leaks than originally present. Ryan visited and sent a drone up to video and photograph the roof and then, told us to check out all his reviews. He offered me an insurance backed guarantee and had many prestigious Which reviews as well as many others. We got a really good feeling immediately and although we had another recommendation it was his professionalism reviews and attention to detail that had me decide on his firm. We were not disappointed! His whole team have been excellent, they cleared up after themselves really well and I from what I can see done an excellent and thorough job! I would highly recommend this firm, I am also recommending them to an insurance contractor who is desperate to find quality roofers.. Thank you Ryan and the team at Harrow Building & Roofing Ltd We are so grateful for you making our home water tight .. Many thanks from Debbie Polverino & Guy Griffiths

Harrow Roofing & Building completely replaced the old roof on our detached residence, including garage and porch, and with extra insulation. From the outset they were skilled, helpful and courteous, with great communications about progress and timings (especially during rather inclement weather). The initial assessment was thoughtful and detailed, with everything well explained. The quote/cost was very fair, and very good value for the excellent quality of the work and workmanship. The extra item that was needed mid-project was fully explained and the quote/cost again very fair. The work was managed very well, and we were kept watertight throughout! The chaps on the teams involved were a delight to have on site, very pleasant and practical, keeping things tidy and as clean as possible, with site clearance at key stages. A couple of very minor issues that arose during the project were swiftly resolved. Overall, the outcome was exactly as we wished and hoped for. It enabled us to install solar panels and also do external decoration with the scaffolding that was needed for the combined project. It is always a pleasure to work with and to recommend professional tradespeople who know what they are doing and take a pride in doing it well.

I called Harrow Roofing and Building as I needed some roofing repair to my mum’s house. After searching through google I decided, from its reviews, to try this company. Honestly from first leaving a message (tbh, fully not expecting a response as has happened with so many other companies for different things in the past) I got a message back from Ryan, apologising for the delay and he sorted a quote, did the work at our convenience, his colleagues were punctual, polite and tidied everything away afterwards. To me, this is a good, honest, reliable Company, I would highly recommend.

Roof repair by Harrow Roofing

I'd recommend Harrow Roofing for any roofing repairs or issues. Living in Banbury, we had noticed a minor leak that had started to damage our back bedroom paintwork. Many local roofers came around, and all of them wanted to go on a hunting mission to remove tiles and batoning to find the leak. I kind of understood this, but with no specifics, and the scaffolding, it was going to be an expensive job, with no real guaranteed. I was recommended Harrow Roofing from an old friend, and they kindly agreed to come a ways up the M40 to take a look. Ryan turned up on time, flew his diagnostic drone across the roof, and immediately saw a number of cracked ridge tiles. He gave me a very reasonable quote to fix and repair. The job took a day, with scaffolding set up the day before. It was completed as agreed within 2 weeks, very professionally, leaving the area clean and tidy. 4 weeks later, my damp meter indicates the area affected is drying nicely. Excellent communications throughout, great value, and went the extra mile (literally). Thankyou

I recommend this company highly and will always use them for any roofing work. Ryan's team fitted a porch canopy and tiled the roof. They checked in with me at all stages, advised me on roofing materials and made sure that the final job was as I had expected. It completely exceeded my expectations due to Darren going over and above with attention to detail. The quote for the work was very fair and invoicing was completely straightforward.

Harrow Roofing replaced our 220 yr old roof with new clay tiles, insulation (for the first time ), new battens, guttering, and other repairs to bring the roof up to modern standards. They did a lovely, quick job and it has transformed the house. The colour of the tiles blends beautifully with the original brickwork. We had subsidence just before they were due to start in 2018!! but years later our house was stable enough for this work to start and it was worth waiting for Harrow Roofing. They also converted part of the roof space and we now have an extra room up there, and best of all, a new, large loft space all insulated and boarded etc. The team were really good and polite. We were out at work every day and could trust them to get on with it. Ryan kept us up to date with photos via WhatsApp. We also had plastering, carpentery, electrics, and painting inside and out. A big job but glad we finally did it. We recommend Harrow Roofing for high-quality work, done with care on an old building.

In August 2023 we decided to get our roof redone (having already had two quotes during the Pandemic) : new roof, gutters, facias, soffits. We picked Harrow Roofing as Ryan Harry was very responsive and straightforward. He was keen that everything was done by the book, Building Regs, etc. He checked our loft and was very patient with all our questions. Because we had already done most of our homework with the two earlier quotes, we felt confident about proceeding quickly. The work started late August with Darren and Chris. There was a heatwave at the time but they both worked fantastically hard throughout, and Darren also was very patient with our queries. We could see the leadwork was beautifully done compared to our neighbour’s recent reroof. We wanted clay tiles rather than concrete, and the roof now looks lovely, like it would have done when first built. They also refixed the original ridge tiles and obtained some extra ones from a nearby house which was discarding theirs. Unfortunately part of our chimney stack broke off during the work as it was leaning away at the top. Ryan had joined the other 2 on the roof that day and he was able to deal with the issue straightaway, putting up a temporary support, and arranging for a bricksmith, extra scaffolding & platform. The problem was dealt with most impressively. It delayed the roof work by about a week which must have affected Ryan’s own work schedule. We are extremely pleased with the quality of work.

Harrow Roofing came out on-site to inspect a suspected leaking gutter. We had a damp patch on the second-floor internal wall not on the ceiling. Harrow Roofing used a drone and showed a damaged roof on a smartphone, showing the roof needed replacing, which had been in situ for 30 years. We suggested fiberglass replacement, and we were advised by Harrow Roofing that they replace a fiberglass roof nearly every week. because they crack and there is no flexibility in this material. Harrow Roofing recommended replacing it with a felt roof., if it lasts another 30 years we will be happy. We agreed on the quotation including scaffolding, the work was carried out on time and we are very happy with the service. We will definitely recommend it to others. The work was very pleasant and professional.

A large flat roof with GRP had failed so Harrow Roofing did a complete change of decking and flat roof to three layer felt. Ryan gave good advice and a fair estimate for the work with the option of a 10 year insurance backed guarantee. His team completed the work efficiently, left the site tidy and the roof looks great. The work was done to the original estimate. They acted in a professional manner with good communication at all times.

Harrow roofing fitted a new slate roof for me at my sister's house in Wimbledon. Their service was first rate. Ryan gave a reasonable price for the work to begin with and arranged scaffolding around the entirety of the property. His team were on site on the agreed start date and thereafter were very tidy, polite, diligent and easy going for the duration of the re-fit. This included work being done in the rain. My sister was also pleasantly surprised at how unobtrusive the team were whilst working on the roof. The job took about two weeks to complete. All rubbish was removed and they tidied up after the work was finished. The whole experience was very professional and I cannot recommend them highly enough.

To replace two rear flat roofs, this will mean to clean and prepare the GRP for a overlay system which will consist of 3 layers. A tack on layer follows by two torch on felts, a 3mm and a cap sheet- technotorch Icopal. Price of works two thousand pounds 15 year guarantee To remove all the ridges, hips and rear verge, setting aside for reuse. The valley will be cut straight and any broken tiles replaced, and all cement work will be replaced using a Mortar mix with added PVA for strength. Price of works one thousand six hundred 10 year guarantee This work was done to put right previous builders work. I liked the fact that they communicated well. Came when they said they would and stuck to quote apart from some minor unforeseen costs
