Trusted flat roofing specialists
covering Hampshire since 1949
If you own a home or commercial building in Hampshire, the odds are there is a flat roof somewhere on it, over an extension, a garage, a porch or a dormer. Clarke Roofing has been carrying out flat roofing in Hampshire and across the wider South East since 1949, working from our base in Eastbourne. This page covers the flat roofs we see most often on Hampshire properties, the systems we install, what the county's weather does to a roof, and how we approach a job from the first look onwards.
Hampshire's housing covers a lot of ground, and so do its flat roofs. Portsmouth and Southampton are densely built cities where Victorian terraces sit alongside large amounts of post-war housing, much of it rebuilt after wartime damage, and a great deal of that stock carries flat roofs over rear additions, bays and outbuildings. The market towns and villages around Winchester, Romsey and Petersfield have older properties where extensions have been fitted around chimneys and party walls, often with flat roofs that were laid in felt decades ago. By the time we are asked to look, that felt is usually blistered or split and the deck beneath has gone soft.
We work on newer property too. The estates spreading around Basingstoke, Andover, Eastleigh and Fareham use flat roofing on garages, porches and single-storey extensions, and these need careful detailing if they are going to hold up over the long term. Flat roofing in Hampshire covers the full range of property age, with century-old terraces and roofs finished last year both on our books.
A flat roof is never truly flat. It carries a slight fall to drain water away, and when that fall is wrong or the waterproofing fails, water pools and finds its way inside.
Hampshire's geography makes this worth taking seriously. The Solent coast around Portsmouth, Gosport, Lee-on-the-Solent and Hayling Island takes salt air and strong winds off the water, both of which cut the life of a roof short if the wrong materials are specified. Inland, the chalk downland and the eastern edge of the South Downs around Petersfield sit higher and take more weather. Near the New Forest and on properties bordering woodland, mature oak and beech drop debris that blocks outlets and causes ponding. The right specification for a roof depends a great deal on where in the county it sits.
We install new flat roofs on extensions, garages, dormers, outbuildings and commercial buildings. We repair flat roofs, dealing with leaks, ponding water, storm damage and failed seams. Where a roof is past saving, we strip back the old covering and rebuild from the deck up. For customers who want one, we install green roof systems with planting and proper drainage. Our installers are trained across every part of the work, and all of it meets current Building Regulations.
The right system depends on the building, how the roof will be used, and the budget.
Single-ply membranes are lightweight, durable sheets that need little maintenance and suit homes and commercial premises alike. Built-up bituminous felt uses bonded layers for a strong waterproof finish, and we follow the NFRC safe2Torch guidance on every installation. Liquid waterproofing cures into a seamless coating and handles awkward upstands and details well. EPDM rubber is a tough membrane that has become a favourite for domestic extensions and garden buildings.
We are accredited installers for Bauder, Sika, IKO, Langley, BMI Icopal, Garland, Westwood, Soprema, Proteus, MOY, Danosa, Carlisle and Baileys, so manufacturer-backed guarantees are available on many of the flat roofs we install in Hampshire.
We look at what is already on the roof before we price the work. Our estimators can take core samples of the existing build-up where it helps, so we understand how the roof was constructed and can recommend what actually suits the building rather than the cheapest patch that will fail again next winter. Whatever we find, we tell you straight.
For most flat roof replacements, Building Regulations approval is needed. We are part of the NFRC Competent Roofer scheme, which lets us self-certify the work and issue a Building Regulations Completion Certificate ourselves, so you do not need to involve Building Control separately. A typical domestic flat roof on a garage or extension usually takes one to three days depending on weather and preparation, and we give you a realistic timeframe when we quote.
How long should a flat roof last in Hampshire?
A quality single-ply or built-up felt roof, well installed, should give 20 to 30 years, and EPDM can last longer. A felt roof laid cheaply and badly might only manage 10. The system you choose and the standard of the work make the biggest difference.
Can you repair my flat roof, or does it need replacing?
Often a repair is the right answer. Sometimes it only postpones a replacement that is due. We will inspect the roof and give you an honest opinion.
Do you work on listed buildings and in conservation areas?
Yes. We have experience with period property across the South East, including conservation areas and listed buildings, and our heritage team can advise on what is likely to be acceptable.
Do you carry out commercial flat roofing in Hampshire?
Yes. We install and repair flat roofs on commercial and industrial buildings as well as homes, and we can take a project on as main contractor where it needs more than the roof.
Flat roofing is one part of what we do in Hampshire. We also carry out slating and tiling, leadwork, zinc and copper roofing, and green roof installations. Our heritage team restores roofs on period and listed buildings using traditional methods and materials. Beyond roofing we offer carpentry, brickwork and decoration, and as VELUX certified installers we fit rooflights. Where a job needs more than a new roof, we can often handle it as main contractor.
We carry out flat roofing in Hampshire including Portsmouth, Southampton, Winchester, Basingstoke, Andover, Eastleigh, Fareham, Gosport, Havant, Petersfield, Romsey and the surrounding towns and villages, alongside our work across the South East such as East Sussex, West Sussex, Kent, Surrey and we also cover work in London.
Whether you need a new flat roof on an extension or new build, a repair on a roof that has started to leak, or a full replacement, we can help. Clarke Roofing has been carrying out flat roofing in Hampshire and the surrounding counties since 1949, and we understand the county's mix of coastal, town and rural property.
