FAQs

How do I know if I need a full new roof or just a repair?

It usually comes down to the extent of the damage and the age of the materials. If you have a few slipped slates or a small leak after a storm, a repair is often enough. However, if the felt underneath has perished or the tiles are crumbling due to age, you might find yourself paying for constant small repairs. In that case, a new roof is often more cost-effective in the long run. We provide honest assessments and will never suggest a full replacement if a repair will do the job.

Do I need planning permission for a house extension in Buckinghamshire?

Many smaller extensions fall under "Permitted Development," meaning you don't need full planning permission as long as you stay within certain limits regarding size and height. However, there are still rules to follow, and you will always need Building Regulations approval. If you live in a listed building or a conservation area, the rules are stricter. We can talk you through the local requirements for your specific area during our initial visit.

How long does it take to install a new roof or build an extension?

A standard domestic roof replacement usually takes between 3 to 7 days, depending on the weather and the size of the house. For a house extension, the timeline is longer, typically ranging from 8 to 16 weeks depending on the complexity of the build. We always give you a realistic schedule before we start so you can plan your life accordingly.

What is the best material for a flat roof?

For most domestic properties, we highly recommend EPDM rubber or modern GRP fibreglass. These materials are much more durable than the old-fashioned pour-and-roll felt of the past. They are jointless, meaning there are fewer places for leaks to start, and they can last for 30 years or more with very little maintenance.

"Building an extension in a Conservation Area felt incredibly daunting, but the team at Firmus handled absolutely everything. They navigated the local authority planning and UK Building Regulations without a single hitch. The new space has completely transformed our home and blends perfectly with the original brickwork."

James L., Buckinghamshire

"When we had a severe roof leak during the last heavy storm, Firmus came out to Thame almost immediately. Not only did they stop the leak that same day, but they also did a fantastic job restoring our crumbling chimney later that week. Fast, reliable, and our home is finally weather-proof again."
