Real reviews from real homeowners across Hampshire, West Sussex, Dorset and Devon.
"Absolutely brilliant from start to finish. The team turned up when they said they would, gave a fair price and the new roof looks fantastic. Cleaned up properly too. Highly recommend South West Roofing."
Sarah M.
Southampton, Hampshire
"Had a bad leak after a storm and they came out the next morning. Sorted the slipped tiles and re-bedded my ridge for a really reasonable price. Proper local roofers — couldn't be happier."
James P.
Chichester, West Sussex
"Replaced our guttering and fascias and the difference is amazing. Polite lads, tidy work, no mess left behind. Will definitely use them again for the back roof next year."
Linda T.
Bournemouth, Dorset
"Full chimney rebuild with new lead flashing. Quote was clear, work was top quality and they kept me updated throughout. Best tradesmen I've used in years."
Mark R.
Exeter, Devon
"Honest, reliable and fairly priced. They fixed a damp issue two other roofers had told me needed a full re-roof — turned out to be flashing. Saved us thousands."
Helen W.
