Your roof plays a vital role in safeguarding your home from the elements. Whether you’re dealing with a deteriorating structure or building from scratch, one of the most common questions we get at KNJ Roofing is- how much does a new roof cost in the UK, particularly in Dorset?
Replacing a roof offers numerous benefits-enhanced insulation, improved structural protection, boosted curb appeal and potentially increased property value. However, the overall cost of a new roof can vary depending on several factors, including the type of roof, material choice, size and location.
If your roof is showing signs of age or damage, it may be time to consider a full replacement rather than patching things up. Here are some indicators that your roof may need replacing-
Several key elements will determine how much your roofing project will cost in Dorset-
Nationally, the average cost to replace a roof ranges between £5,000 and £8,500, though larger and more complex installations (like a slate hip roof) can reach up to £18,000. In Dorset, pricing usually aligns with the national average, but variables such as property height and accessibility may cause slight deviations.
Replacing a roof is a substantial investment and should always be handled by experienced professionals. At KNJ Roofing, we recommend collecting several quotes and ensuring each includes a thorough on-site assessment.

Flat roof specialists, years of experience and completed works.
Mr and Mrs Harrington, a retired couple living in the quiet outskirts of Poole, had spent over 30 years in their charming thatched cottage. While the roof was a beautiful and defining feature of their home, it had become increasingly difficult-and costly-to maintain. Years of patchwork repairs had taken their toll and after the most recent winter storm caused extensive leaking in the lounge ceiling, the Harringtons decided it was time for a full roof replacement.
Being a listed property, the couple needed a solution that preserved the cottage’s character while offering improved durability, energy efficiency and minimal future upkeep.
KNJ Roofing began with a full site inspection, carefully documenting the condition of the existing thatch. The roof was heavily degraded, with several areas showing rot and moss accumulation, increasing the risk of pest infestation and fire hazard.
We consulted with both the local conservation officer and the clients, proposing a sympathetic alternative- a thatch-effect composite tile system designed to replicate the appearance of traditional thatch but meet modern fire safety and insulation standards.
This offered a perfect balance-visually in keeping with the surrounding area and local planning requirements, but far easier for the couple to maintain as they grew older.
The process was carefully staged to minimise disruption-
Mr and Mrs Harrington were delighted with the result-
A conservation inspector signed off on the work, confirming full compliance with local heritage guidelines.
“We were heartbroken at the thought of losing our thatched roof, but KNJ Roofing offered a solution we never knew existed. It still looks like the home we fell in love with all those years ago-only now we can sleep through a storm without a bucket nearby! Professional, thoughtful and respectful throughout.”
– Mr & Mrs Harrington, Poole
