The Best Roofers in Watford, Hertfordshire, United Kingdom (2025)

We chose Harrow Roofing & Building when building this new house as they were recommended by another builder. Their initial quote was detailed, well explained and very competitive. On site, the team were polite, professional and efficient. Upon completion of the project, the result is beautiful. We've had many people stop us on the drive to compliment us on the superior finish of the house. Would highly recommend Ryan and his team.

I just used Harrow roofing on two jobs recently for family and they have been exceptional. One in Cuffley and the other in North Finchley. Their customer service was really helpful and you can really trust them to give you a fair quote. Both jobs were done within a week of enquiry and pictures before and after the job were provided.

I’m extremely impressed with the professionalism and quality of work from the Harrow Roofing & Building team (Stewart and Kiren ) who repaired our flat roof today. The team arrived on time, worked efficiently, and clearly knew what they were doing. The attention to detail was outstanding—from the thorough inspection to the flawless finish. They also made sure to keep everything clean and tidy, which I really appreciated. The flat roof looks great and is holding up perfectly. I wouldn’t hesitate to recommend them to anyone in need of roofing work—fantastic job all around!

Ryan and his team are the best roofers I've used. Has carried out several roofing jobs for my company. Professional and produces excellent quality workmanship and could not recommend highly enough. A+++

Roof work by Rooftops, Watford (to re-cover bay window) looks good. Very satisfied.

Great service from the moment I called up to initially get a quote and to completing a full repair of my roof. Ewalina who took the call was very helpful, answered all my questions. I was then visited by Les (friendly and approachable) who took a look at the issue (ridge, loose tiles and gutter) with my roof and was able to give me a full quote (best quote I got compared to other roofering companies) and booked in the job which I did not have to wait long for the works to be carried out. Dave (experienced roofer, friendly, approachable) the roofer and his assistant came, they cracked on and within a few hours it was all sorted. I would definately use and recommend ROOFTOPS for roofing jobs. Very efficient team and quality work. Thank you all for the great job, well done.

Very professional and organized. Roof had to be overhauled (slipped tiles, tiles replacing, re-pointing). The work was very well explained and the team did a good job and left the place tidy. Anytime again!

I’m so glad I chose All Custom Roofing for my roof replacement. The crew was professional, thorough, and made sure everything was done correctly. They finished the job ahead of schedule, and I couldn’t be happier with the results.

All custom roofing did a good job putting new guttering on my house

The team at All Custom Roofing was fantastic. They completed my roof installation on time and ensured everything was done correctly. I’m very happy with the quality of work. I would definitely hire them again for future roofing needs.

Really excellent service from Blue A. We had a garage roof removed by them and they've been professional and efficient throughout. I had a number of questions in the run-up to the removal and they always answered properly and promptly and we always knew what was happening. All the certificates etc. they provided, including about proper disposal, were really reassuring. The removal went really smoothly and the team that came on the day were friendly, careful and considerate. I'd really recommend this company.

Excellent service from Blue A. We removed our asbestos ceilings from the downstairs of our 4 bedroomed house and then the ceilings reinstalled and replastered. Right from the start we had good advice and clear communication from Blue A. The quote was not the cheapest we had but also not the most expensive and they were absolutely worth it. House was left tidy with new ceilings and looks 100% better than it was. We will definitely use them again to do the upstairs.

Absolutely brilliant service all-round! From survey through to removal Blue-A were efficient and professional. We had significant amount of asbestos ceilings identified across our property and needed to have it removed, Blue-A were able to complete this in just a few days of work on site. (Example pictures of one of the 7 areas completed attached.)

We use Blue A for asbestos removal and they work across many sites. They have consistently provided a 5 star performance on site both in terms of safety on site and also quality of work.

We recently had our roof replaced, and we couldn't be happier with the results! The team was professional, efficient, and left our property spotless. Highly recommend!

Been using Liam and his team on multiple refurb projects. Cannot fault them . Their attention to detail is exemplary And it's rare to find tradesmen who i feel totally comfortable dealing with my discerning clients when I am not on site myself. Looking forward to continuing our business relationship in the future. Such value , quality and trust is hard to find

We thought we simply had 1-2 slipped tiles! It quickly became clear that the damage was more severe. Liam talked us through the options of repair / complete renewal. Despite the cost we opted for a new roof as Supreme could remove/ re-install the existing solar panels. The team onsite were polite, efficient and left the site tidy each day. We were kept informed as to what was happening and when they would be onsite. The work has been done to the highest standard and really enhances the property. Supreme were flexible about funding everything at short notice. We thoroughly recommend them.

So so happy with the work done on my house from Supreme Roofing. They had worked on the porch & roof and it's exactly what we wanted! 10/10 communication and was so reliable, couldn't recommend anymore. Have already passed the details over to a few friends. THANKS AGAIN!

From first call to the finished job Darren and his team were courteous and professional. They diagnosed the cause of the leak as the Box Gutter, provided photos of the inspection and explained the options available - both a temporary fix and long term solution. We decided on having it stripped out and replaced and the fix was organised within the week. Darren and his assistant worked efficiently, again showing us photos of each stage which was reassuring. On completion the area was cleaned down and Darren made sure to explain what they had done and provided written description of works. Couldn't be faulted

Darren explained exactly what he and his team were going to do, so we felt completely confident. He and his team were friendly, efficient and thorough. They left the work area spotless and we are very pleased not just with the re-roofing but also with the competitive pricing. Thank you!

Darren very promptly came out and viewed the problem with my roof. He provided me with a fast and reasonable quotation. The repairs were completed without fuss and I'm very happy with the services and level of professionalism. Highly recommend!

We used this company as we needed a roof for our new extension. Quoted us for free and was really helpful in planning etc. Darren and his workmen put in 3 skylights for us too which are of great quality. Our neighbours have booked him to do their roof. Good quality service and price.

What a great company. I needed some roof tiles, felt and upvc edging for a couple of DIY projects. The lad at the counter couldn't have been any more helpful and the staff bringing the materials were quick and efficient. Definitely highly recommended.

Fast and reliable service, friendly staff and competitive prices.

Just came back from their Watford branch after buying some tiles. Extremely professional and polite staff. Best prices for roofing materials. Thank you Skyline for being there for trade and non trade customers.

Went to skyline today and received excellent customer service at the till , very polite and very helpful when needing advice etc, The guys in the yard got my order together very promptly and loaded everything for me I highly recommend skyline
