Frequently Asked Questions
Find answers to some of our most commonly asked questions below. If your question isn’t answered below, feel free to get in touch with our friendly team!
Most standard residential roof replacements are completed in one to three days. Larger or more complex roofs with multiple valleys or dormers can take up to a week.
In most cases, no. Roof replacements on standard residential properties typically fall under permitted development rights, though listed buildings and conservation areas may differ.
Persistent leaks, sagging sections, widespread tile damage, visible daylight through the roof structure and recurring condensation all point to replacement rather than repair.
It depends on your priorities. Tiled and solid roofs offer superior thermal performance, glass roofs maximise natural light, and hybrid systems deliver a balance of both. Our team will help you choose.
The cost of a conservatory roof replacement will vary depending on the roof system you choose, your existing conservatory and the size.

We have had an outstanding service from Malbern, dating back to 2014 when they built my conservatory, over the intervening years when we needed a small bit of maintenance under the guarantee, and most recently when they have replaced the glass roof with a solid roof, transforming the original design. This has given us a brilliant new room in 2024 and made our house feel much more spacious and better insulated. The build team took care of the whole process, doing a very professional clean and tidy job. I can't recommend more highly!

Just completed a full conservatory build and all we can really say is that we are extremely amazed at the quality of the end result. Fantastic, brilliant, overjoyed, perfect, better than expected. After the initial meeting we had a picture in our mind of what we wanted but the end result is so much better than expected. We certainly can't complain, it is a job well done and money well spent. Now it's time to enjoy the final end result. A massive thank you to all involved.

Malbern recently built us a large conservatory and a garden room. This was a massive job involving levelling a terraced garden and putting in retaining walls in addition to the conservatory and garden room construction. They did a fantastic job, all the work was done to a high standard and any snags were quickly dealt with.
