Highlights
"I cannot thank Jim enough for his work. He was very helpful when I encountered some rogue roofers who left my house leaking all night. He came once contacted and did his survey and explained what needed to be done. We arranged a date for the job and he came as promised and did a fantastic job. He even asked us not to pay until it rained and when it rained, there was no single leak. Thank you Jim."

James and team really helped us out fitting us in to replace a flat roof which was old and leaking which had caused some internal damage too. Initial assessment done and then a quick appointment, offering to come on the weekend if needed to fix our issue. The team were polite, explained what they were recommending and why. They were quick on the job, but clearly doing a quality job and some extra effort to tidy up inside where the internal ceiling had been damaged. Thanks, great value for money, would definitely use them again and recommend.
Jim showed up on time and was very informative. Although we didn't go forward on this occassion we were very impressed with his level of knowledge and professionalism. If i need to get any work done again, i will definitely be giving him a shout in the future.
Despite being busy, John came to assess the job the same day I called. He then offered to do a full no-obligation assessment at no cost the following day, which he did. I was happy with the quote and gave the go-ahead for the work to be done. I felt that John was very informative and did not make me feel under pressure to have anything done. The work was of a relatively minor nature in the grand scale of things, but he was good enough to reassure me that the roof in general was in good shape. Members of his team were also very polite.
Jim Davis and his team replaced the guttering, soffits and fascia on our home and replaced the roof and guttering on our garage. He is a very polite and pleasant man who you feel immediately comfortable with, and his work is first rate - Mr Okosi, Potters Bar.
Second project they’ve done for us, replacing a shared gutter at the front of the house. The rear of the house was done in the Spring. Hopefully the whole house is sorted for years to come now but wouldn’t hesitate to use them again.
Been done over by Peter Smith at Surefix Roofing and was so worried if it happened again, JJ Roofing assured me they would rectify that work and help me out with what I have already spent. The standard of work and the professionalism is very high. Took me up on the roof, showed me the issues and didn’t ask for payment until the leak was gone. Highly recommend, there won’t be any issues with these guys and I won’t use anyone else moving forward. Bobby
Supplied and fitted guttering quickly and efficiently. Polite and friendly team were considerate and left zero mess. Great communication. Would defo recommend!
Very polite, brilliant work. Very pleased.
Replaced and repaired broken guttering and roof tiles.
After asking a number of roofers to undertake some lead flashing repairs to a roofing canopy and getting no response, i noticed JJ Roofing were doing work for a couple of my neighbours. When i approached James and asked if he could give a quote, James said he could do the work the following Wednesday and true to word he did and the results were excellent. JJ Roofing tidied up so well afterwords, you would not have known there had been any workmen there. JJ Roofing did themselves proud and will be my 1st call for any future roofing or gutter work and i would not hesitate to highly recommend them to any of my friends, family or neighbours. Thanks James & the JJ Roofing team.
Delighted with the result! Good price, professional service- I highly recommend.
Really nice team, pleasure to have round.
Great service, good, professional approach, really tidy afterwards.
Carried out the work as agreed and cleaned up all the mess and debri from working.
I contacted JJ Roofing after using another guttering company who failed to fix my leaking gutters after several attempts. James was reliable and gave me a quote over the phone the same day, he then came and fixed my guttering leaks the following day. I found JJ Roofing to be honest, reliable and efficient and would certainly not hesitate in using them again or recommending them for any roofing repairs.
