FAQs for Hersham
Does a conservation area affect roof work in Hersham?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover Hersham?

What does a roof survey cost?

Roof leak investigations for homes and businesses in Hersham
Leaks tend to begin where one part of a roof meets another. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. We check each likely route and we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. We look at all of them, from every safe viewpoint. If you are worried about damp underlay across a wide area and damp on a chimney breast, a survey will tell you what’s going on, on slate and tile slopes, valleys and parapet gutters and chimney stacks alike.
In older homes around places like Hersham, the underlay may be old bitumen felt, or there may be none at all. Without a sound underlay, any gap in the coverings lets water straight through. Whether it’s long-term wear or recent damage makes a difference to what happens next. In the loft, damp battens or wet insulation are often the first clues.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What we look for on each type of roof
Lead flashings
Mortar fillets are sometimes used instead of lead. Fillets crack and pull away over time, and water runs down behind them.
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. A blocked outlet sends water over the lining and into the building.
Why it’s worth a survey now in Hersham
Water and electrics do not mix. If water is reaching a light fitting or switch, keep clear of it and have an electrician check it. Finding where the water is getting in should follow straight away. In a smaller place like Hersham, wherever a roof is exposed, a loose ridge or flashing doesn’t stay loose for long. Wind gets under it and lifts more, and water follows.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 with VAT included. We will tell you which package suits the questions you have.

Practical tips
Over many surveys, some simple habits stand out:
- Do not touch fittings that water is reaching
- Note the weather when the leak shows
- Clear the loft hatch so we can get in
- Tell us if there are tanks or pipes in the loft
Keep the report after the work is done. If water appears again, it shows what was found before.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.
Hersham roofs and the weather
The wider area around Hersham has a long history of building, with The Homewood about 1.4 miles south-east. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Older houses across Surrey frequently have handmade clay tiles, and many have tile-hanging. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
If you look after a building such as Bell Farm Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you live in an older home near Church of St Peter, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

The survey, step by step
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes about one to two hours, more where the leak is intermittent or the roof is large. Some parts of a survey depend on the weather, so a visit to Hersham is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from the ground and the loft can go ahead in most weather.

Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the loft space.
