Waterlooville and the villages around it are mostly postwar and later, with coverings now old enough to need decisions. We inspect, repair and replace roofs across Waterlooville, Cowplain and Purbrook.

Waterlooville is largely a twentieth century town. A small older core, then decades of steady expansion through Cowplain, Purbrook and Widley, most of it built between the 1950s and the 1980s. That means concrete interlocking tiles on trussed rafters, mortar-bedded ridges and verges, timber rooflines on the older stock and uPVC on the newer, and a garage or extension flat roof on a large share of properties. Sitting up against the chalk downland also means more wind than the numbers suggest, particularly on the higher ground towards Portsdown and Horndean. Wind works on the edges of a roof, so verges, ridges and eaves are where we find most of the failures here, along with flashings where an extension meets the main wall. Very few of those jobs need a full replacement. Most need the failed detail replaced properly with something that will not come apart the same way again.
Most Waterlooville roofs we are called to have failed at a detail, not a covering. A cracked ridge, a shelling verge, a flashing that has worked loose where an extension meets the wall. Re-bedding it in mortar puts you back on the same clock, so we will tell you when a mechanical system costs more now and less over ten years. Fifteen years of roofing, one team for tiles, leadwork, ventilation and roofline, and a written quotation that sets out what we propose to replace and why.
Our experienced team has worked on pitched roofs, flat roofs and roof structures across Hampshire, from minor domestic repairs to full replacements and specialist structural timber work.
We inspect, repair, replace and maintain the whole roof system, from tiles and flashing to timbers, ventilation and guttering, so you never need to appoint several different contractors for one roof.
We recommend the work your roof genuinely needs, never a full replacement by default. Every quotation is clear and written, with free, no-obligation advice to help you decide.
Ridges, verges, extension leaks and loft ventilation account for most of what we are asked here. These are the questions that come up across Waterlooville, Cowplain and Purbrook.
Yes. Ridge, tile and eaves ventilation, and ventilation improvements where a loft is showing condensation on the underside of the felt. Poor ventilation is a common cause of damp that gets blamed on a leak, and it is usually a straightforward fix.
Waterlooville, Cowplain, Purbrook, Widley, Denmead, Hambledon and out to Horndean, Havant and Portsmouth. Call with your postcode if you are on the edge of that.
Yes. Free survey, free written quotation, no obligation, and free initial advice if you simply want a view on whether work is needed yet.
Yes, including after old insulation has been removed or damaged. We can also improve ventilation at the same time, since insulation and ventilation have to work together or you swap one problem for another.
Often it is the abutment rather than the roof surface. The flashing or upstand where the flat roof meets the wall is the most common failure point, and it can be repaired without touching the rest. We confirm which it is before quoting so you are not paying for a new roof to fix a flashing.
Mortar bonds the ridge tiles to the roof and eventually cracks, particularly on exposed roofs. A dry ridge system holds each tile with a mechanical fixing and includes ventilation at the ridge. It costs more than re-bedding and it does not need doing again in a few years, which on a windy site is usually the better value.
