Very impressed with the new slate roof installation. The workmanship is outstanding, and the materials used are clearly high quality. The team worked hard, respected our property, and finished on schedule. The roof has transformed the appearance of our home. Excellent service and honest pricing throughout.

Flat Roofing
How we approach flat roofing.
Most flat roof failures come from a poor deck, no fall, or blocked outlets rather than the covering itself. We replace rotten boards, build in the correct fall so water drains, and then lay the new system.
We'll recommend the right covering for your roof, whether that's a seamless GRP finish, a single-sheet EPDM membrane or a felt system.
What we cover

GRP fibreglass

Torch-on felt
Multi-layer felt systems for traditional flat roofs.
New decking
Rotten boards replaced with OSB3 and correct falls.
Garage & extension roofs
Full replacements for outbuildings and rear extensions.
Roof lights & outlets
Skylights, trims and outlets fitted and sealed.

Had the guys from Sovereign lower my chimney stack by half and cap it over. They did an excellent job, very efficient and clean. They explained how everything would go from start to finish. I couldn't recommend this company enough.
Great service from start to finish. A few roof tiles were replaced quickly and professionally, and everything was left clean and tidy. Would definitely recommend!
Had some ridge tiles repaired by John and the team. Great communication from start to finish. Described everything that needed doing in great detail. Finished the job to high standards and kept everything tidy. Would definitely use this company again in the future.
Prompt, efficient service. Very friendly guys who did a great job at a competitive price. Would use again.
I had Sovereign carry out some gutter cleaning and they also repaired a leak for me. Would recommend.
