Professional, reliable and high quality work
Ryan and team were professional and reliable from start to finish. I got a new roof competed on time, at the agreed price and no issues since completion. Would highly recommend.

Professional Roofers
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.

I contacted Ryan on behalf of my elderly father who needed some roofing done. From start to finish Ryan and his team were professional and finished the work to a high standard. I cannot recommend harrow roofing and building enough to anyone to who wants a reliable and honest service at a competitive price. Thank you to you and your team.

Wonderful new roof and other works
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.

Gutter & tiles repair
Overall service was outstanding. Thank you Ryan for organising the work so quickly and thanks to Rich and Laurence for their very professional, friendly and efficient work. The work needed some adaptations to the existing gutters and the guys were very accomodating in dealing with these. Great job and much appreciated. Would happily recommend Harrow Roofing.

Very professional
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.

Polite, efficient and great quality service!
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!

Felt Flat Roof, installed in 1993 replaced 18th May 2023
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.

Installation of porch canopy
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.

Excellent roofers, helpful, good communication
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.

Very happy with our new roof.
We are delighted with our new roof, gutters, and associated insulation upgrade, which has just been completed by Harrow Roofing and Building. We have an old character property and wanted the new roof to look like the old one and be in keeping with the property. Ryan and the on-site team were a pleasure to work with and made sure we got exactly what we wanted. They were courteous and always left the site clean and tidy at the end of the day. We would gladly recommend them.
