“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

A sound roof is the cheapest damp-proofing you will ever buy
A roof rarely fails all at once. Slipped tiles, tired felt, cracked flashing and blocked valleys let water in slowly — and by the time it shows on a ceiling, the timber, insulation and plaster below have often been quietly soaking for months.
Because we are damp and timber specialists first, we look at your roof the way water does: where it gets in, where it travels and what it damages on the way. That means we fix the actual defect rather than simply patching the stain it left behind.
From individual repairs to full re-roofs and the RENOTEC coating system, every job is carried out by our own team using quality materials, and finished to a standard that keeps your property dry from the top down.
The roofing problems we put right
Most roof-related damp comes down to a handful of common failures. Our inspection confirms exactly which one you are dealing with before any work is quoted.
Slipped & missing tiles
Wind, age and failed fixings leave gaps that let rain straight into the roof void, soaking felt, timber and the ceilings below. Left unattended, a single slipped tile can lead to widespread water damage.
Failed flashing & pointing
The lead flashing and mortar around chimneys, valleys and abutments is where most roofs leak first. Once it cracks or lifts, water tracks in around the joint and shows up as damp on internal walls.
Worn or ageing roof coverings
Tired felt, porous tiles and a roof at the end of its life let moisture through across a wide area. A re-roof or the RENOTEC coating system restores a fully weathertight surface.
Blocked gutters & rainwater goods
When gutters and downpipes overflow, water runs down the walls instead of away from them — one of the most common causes of penetrating damp at high level.
Real roofing projects across the South
Every job below is a genuine Proofterior project across Dorset, Hampshire and Wiltshire — diagnosed properly, repaired at the source and finished to a lasting, weathertight standard. Click any project to see the before, after and exactly how we put it right.
The warning signs to look for
If you recognise any of these, it is worth having the roof looked at before the damage spreads to the structure below.

How we put it right
Once the inspection confirms the cause, we use the right method for your roof — never a temporary patch over a bigger problem.
Targeted roof repairs
Slipped tiles re-fixed, damaged coverings replaced and defects made good, so the roof is weathertight again without the cost of an unnecessary re-roof.
Flashing & pointing renewal
Failed lead flashing and mortar around chimneys, valleys and abutments is renewed to stop water tracking in at the most common leak points.
RENOTEC roof coating system
A professional coating system that restores and protects an ageing roof, extending its life and giving a clean, uniform, fully weatherproof finish.
Rainwater goods repair & renewal
Gutters and downpipes cleared, repaired or replaced so rainwater is carried safely away from the walls and foundations instead of into them.

Everything you might be wondering
In most cases a targeted repair is all that is needed — we never recommend a re-roof unless the covering is genuinely at the end of its life. Our inspection tells you honestly which option is right for your roof and budget.
RENOTEC is a professional coating system that cleans, restores and protects an ageing roof, extending its life and giving a clean, uniform, weatherproof finish — often a cost-effective alternative to a full re-roof.
Very often, yes. Damp at high level and on top-floor ceilings frequently starts with a roof, flashing or gutter defect. Because we are damp specialists too, we trace it back to the true source rather than just treating the stain.
Most repairs are completed in a day or two, while re-roofs and coating projects take longer depending on the size of the roof and the weather. We give you a clear timeline before any work begins.
Yes. Our surveyors are ISSE accredited, we are registered for environmental waste carriage, and we hold strong independent ratings across Checkatrade, Google and Yell.
