Roof repairs, new roofs, flat and pitched roofing across Winchester and the SO postcodes. Free inspection, honest written quote, no call-out charge.
Tell us about your roof. We usually reply the same day.
From the period cottages and heritage homes around St Cross and the city centre to the modern estates through Harestock and the surrounding villages of Twyford, Hursley and Sparsholt, Winchester roofs span every age and style, and each needs a slightly different approach. We work across the whole city and the SO22 and SO23 postcodes, and we see the same local problems again and again.
On the older properties near the cathedral and St Cross it is usually slipped or cracked slates, worn chimney leadwork and tired pointing. The newer homes through Harestock and the villages often need ridge and valley work or flashing repairs. And right across Winchester the most common call we get is an ageing felt flat roof on a rear extension, dormer or garage that has finally started to let water in. Whatever your roof, we inspect it properly, show you photos of what we find and give you a straight, written quote.
From slipped tiles to storm damage and leaks, we provide quick, honest repairs to protect your home across St Cross, Harestock, Twyford and the surrounding SO22 and SO23 villages. Our roofers carry out thorough inspections and show clear photos before and after work so you know exactly what has been done. We also offer preventative maintenance plans to keep your roof in excellent condition.
Whether you live near St Cross, Harestock or Twyford, we design and install tiled, slate and flat roofs to match the character of your home. Each new roof is fitted with modern breathable membranes and quality fixings for a finish that lasts decades, and every installation includes a guarantee and photo report for your records. We repair and replace pitched roofs using premium tiles and slates that suit Winchester's mix of modern and heritage homes, rebedding ridges, repairing valleys and installing new lead flashing to keep everything watertight.
We fit and repair felt, GRP fibreglass and EPDM rubber flat roofs for garages, extensions and dormers throughout Winchester. Our systems offer long-term weatherproofing with low maintenance, and we will recommend the best solution for your budget and property type. Flat roof systems come with manufacturer and workmanship guarantees ranging from 10 to 25 years.
We replace rotted woodwork with durable, maintenance-free uPVC fascias and soffits that enhance your home's appearance and protect the roof edge from damp. Choose from white or coloured finishes to suit your property's style. Blocked or leaking gutters can cause serious damp issues, so we also install and maintain modern guttering systems with secure brackets and aligned falls for efficient drainage, and clean and seal existing systems to extend their lifespan.
We carry out chimney repointing, reflashing and repairs to brickwork and pots across Winchester. Lead tray and flashing repairs are completed by experienced craftsmen using code-graded lead for long-term durability and appearance, keeping the older chimneys around St Cross and the city centre watertight and in keeping with the property.
Heavy rain and wind can cause unexpected roof failures. Our Winchester team responds quickly to make safe, install temporary coverings and complete repairs as soon as possible, helping you avoid further damage to your home. We prioritise leaks and storm damage right across SO22 and SO23.
If spray foam is causing survey or moisture issues, we remove it safely and replace it with breathable insulation that complies with UK building standards. We inspect the rafters and issue a clear report once complete, so your roof space is sound and your property is mortgageable again.
Moss build-up can block gutters and hold moisture against tiles. We gently remove it by hand and apply a biocide wash to prevent regrowth, improving roof appearance and longevity without damaging tiles. It is a low-cost way to protect the tiles on Winchester's period and modern homes alike.
Many homes around St Cross, the city centre and the conservation areas need like-for-like materials such as natural slate or matching clay tiles to keep their original look and meet local planning and conservation expectations. We are used to working on period, heritage and listed roofs and match materials carefully. On the tighter streets near the centre we plan access and parking in advance so the job runs smoothly for you and your neighbours.

"Mitchell was the only builder, of many that I had contacted, that climbed a ladder to inspect my flat roof and into my loft to inspect the main roof from inside. He emailed his quotation the same day, the team arrived on time and completed the work to a professional standard with photos at all stages."
"New slate roof. Mitchell and his team installed my new roof and I'm very satisfied. The quality is superb, they were professional, punctual and communicative. The project finished on time and the site was left spotless."
"Mitchell repointed a chimney and installed a chimney cowl, plus some cementing work to the roof. He was very polite and conscientious, kept me informed throughout, and gave me a quote and did the work within a few days. I wouldn't hesitate to recommend Alliance Roofing & Building."
