Felt flat roofs on extensions
Old felt cracks, blisters and lets water in at the edges. We replace it with a single sheet of EPDM rubber, with no joins in the middle.
Flat roofingHome / Areas We Cover / Carlton
A few miles east of the city, from Netherfield terraces to Gedling semis.
Carlton
Carlton is about three miles east of our base. A lot of what we see here is a leaking extension roof, so felt flat roofs swapped for EPDM rubber are a big part of the work, alongside pitched roofs, conservatories and lofts.
The area runs from older terraces around Netherfield and the Carlton side streets to inter-war and post-war semis up the hill towards Gedling. A lot of houses have had kitchens or garages extended at the back with a flat roof, and those are often the first thing to leak.

Flat roofingSlipped tiles, tired ridges and old felt. We’ll tell you whether a repair will do or it’s time for a new roof.
Pitched roofingTopped up to 270mm and boarded, so the rooms below stay warmer and the loft becomes usable storage.
Loft insulationIf an extension roof is leaking, we check where the flat roof meets the house as well, because that’s where a lot of leaks really start.

“Great experience, came on time, good communication. They worked well and did a good job and cleaned up well before they left. The roof looks great, and we now have a conservatory that we can use all year round. Lovely company to deal with.”
“The surveyor who came to measure up and quote wasn’t in the least pressurising and gave me confidence in the company. The installer on the day was efficient but friendly and polite. I am very pleased with the finished product and would not hesitate to recommend this company.”
“Excellent service. Clear quote, efficient team, high quality work completed quickly despite awful weather. Very impressed!!”
“Absolutely brilliant from sales to finishing the installation. Great job all done in six hours. The site was cleared and cleaned up. You wouldn’t know they had been except for a great new roof on our conservatory. If we could award ten stars we would. Highly recommended.”
“Very happy with the service, workmen excellent, polite, cleaned up after them. Will recommend them to my friends.”
“Very satisfied with Cozy Top, excellent work, staff would recommend this company to do a good job, would deal with this company again.”
“Following a visit by the Director of Cozy Top Home, to discuss the best options for my conservatory roof. I placed the order, the Surveyor visited and he explained in full detail how the work would be carried out. The two fitters turned up at the time advised, and worked non stop, they did an excellent job, and tidied up after them. I am extremely pleased with the service provided, and would recommend them.”
“The entire team is brilliant. Gareth came in and provided a free quote, clearly explaining the entire process. David and Mark arrived early in the morning and completed the work within just 4 hours. The work was carried out very professionally and meticulously.”
“We started with the Estimator/Sales Gareth who was very helpful, friendly and discussed how the work would be done. The work was carried out with 2 brothers who had a good work ethic, got on with the job with precision and cleanliness. On completion we had a visit from the company work inspector to check we were happy with the work done.”
