Tell us about your roof. We usually reply the same day.
Didcot has grown faster than almost any town in South Oxfordshire, and its roofs tell that story. The Ladygrove and Great Western Park estates added thousands of modern houses with concrete-tiled pitched roofs, while Northbourne and the older streets near the railway centre still carry traditional terraces and post-war semis. Each age of roof fails for different reasons, and we work across all of them throughout the OX11 area.
On the newer estates the common calls are slipped concrete tiles, ridge mortar that has cracked early, and felt flat roofs on garages and extensions that have started to let water in. On the older terraces near the town centre it is usually worn chimney leadwork, tired pointing and ageing slate. Whatever the property, we inspect the roof properly, show you photos of what we find, and give you a straight, written quote with no pressure.
We work on the full mix of Didcot housing, from the recent developments at Great Western Park and Ladygrove to the established estates around Northbourne and the older homes near the centre. That range means we adapt our approach to each roof's structure and age, matching concrete tiles, clay or slate so repairs and re-roofs sit right and last. On tighter terraced streets we plan access and parking in advance so the job runs smoothly for you and your neighbours.
Roof issues in Didcot often develop through ageing materials, wind exposure and blocked drainage, and many go unnoticed until water ingress or damp appears inside. We carry out targeted repairs that fix the real cause, not just the visible symptom. The problems we see most often are:
Not every problem means a full replacement. Where damage is localised and the structure is sound, a targeted repair is usually the most sensible, cost-effective fix. Where damage is widespread or recurring, we will explain honestly why a replacement is the better long-term option, with no pressure either way.
Much of Didcot's housing stock has pitched roofs fitted during periods of rapid development, often concrete tiles on traditional felt-and-batten systems. These tend to suffer worn fixings, ageing underlay and ridge deterioration rather than sudden failure. Our pitched roofing service focuses on catching those issues early and carrying out work that restores reliability instead of relying on repeat patch repairs. We handle pitched roof repairs, tile and slate replacement, full re-roofs renewing membranes, battens and fixings, storm and wind damage, and ridge work including modern dry ridge systems that improve ventilation and cut maintenance. We work with concrete tiles, clay tiles and natural slate, matching materials carefully to keep a consistent finish across the roof.
If your flat roof is leaking, pooling water or showing its age, we provide straightforward inspections, honest advice and quality workmanship across Didcot and OX11. We work on garages, extensions, dormers, bay roofs and commercial units, from small repairs to full replacements. Flat roof repairs here commonly involve split membranes, damaged felt seams, lifted edges, blocked outlets or weak flashing around joins. We identify what is actually causing the issue, then repair it properly so you are not calling someone out again in six months. We install three main systems:
Standing water is a warning sign: it usually points to issues with the roof falls, the deck beneath or blocked drainage. A proper inspection will tell you whether it is a simple drainage fix, a repair, or a sign the structure needs attention.
If water is coming through your roof, act straight away to reduce the damage inside. Place buckets under any drips, move furniture and valuables clear, and check around the property as water can spread across ceilings into other rooms. If a ceiling starts to dip or crack, keep clear as it may not be safe. Avoid going up onto the roof yourself, especially if it is wet or already damaged. We provide emergency roof repairs across Didcot for leaks, storm damage and unsafe roofing, attending quickly to stop further water getting in, applying temporary waterproofing where needed, then carrying out proper permanent repairs once the roof is secure.
The roofline does the quiet work of keeping water away from your walls and timbers. We install and repair low-maintenance uPVC fascias and soffits and replace tired or sagging guttering across Didcot, fixing the overflow and damp problems that blocked or split guttering causes. We also offer gutter cleaning and repairs to keep drainage clear and your roof edge protected.
Older Didcot properties near the centre often have chimneys where the leadwork, flashing or mortar has worn over time, and that is a frequent source of leaks. We carry out chimney repointing, lead flashing renewal and brickwork repairs to restore a watertight seal, and we fit chimney cowls where needed. Where a chimney is no longer used, we can also remove the stack below the roof line and make good the roof covering.
Moss holds moisture against tiles and blocks drainage channels, which speeds up wear and can lead to leaks. We remove moss by hand, protecting your tiles rather than blasting them, to improve drainage and keep your roof in good condition. It pairs well with a roofline check so any underlying issues are caught at the same time.
