What affects the price in Charlwood
Prices vary from roof to roof, and it comes down to:
- Building height and the viewpoints available
- Chimneys, valleys, parapets and other details
- Commercial roofs and larger buildings
- How big the roof is
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
What to tell us when you get in touch
The more you let us know, the easier it is to price the survey. When you contact us, it is useful to mention:
- Your postcode, so we can check access and travel
- The reason for the survey, such as buying, a leak or storm damage
- Dates you are working to, like exchange
- Anything about access we should know
A quick phone call is typically the easiest start: call 07833 053749 or email us, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.
Electronic leak detection in Charlwood: what you get
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points rather than guessing. Repair costs aren’t part of the report; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a report with photos. We survey flat roof membranes, green roofs and roof terraces and balconies, and people most often book us about patched roofs that still leak and damage from equipment installers.
Older buildings in small places like Charlwood may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
We write the report in plain English, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put in order of urgency where relevant.

Flat and commercial roofs around Charlwood
Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Bentworth Hall, about 4.8 miles north, is one of the historic houses in the wider area around Charlwood. 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 the council can say whether a home is in a conservation area.
Charlwood is about 6 miles south-west of Alton, in Hampshire. If you’re in Charlwood, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Our Hampshire coverage includes Charlwood. For surveys nearby, see our Southampton page.

How the survey works
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe vantage point, take photos as we go and make notes for the report. It typically takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Somewhere like Charlwood needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before the survey
- Check we can get to the back of the property
- Make a note of anything you’d like us to look at
- Clear the way to the loft hatch
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or send us an email.
Advice
Why act early in Charlwood
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. For an older or listed building in a place like Charlwood, repairs may need matching materials and consent, so leaving a defect until it is urgent leaves less time to plan.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

FAQs for Charlwood
Does a conservation area affect roof work in Charlwood?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is Charlwood in the area you cover?
Yes. We survey roofs across London and South East England, and Charlwood is part of that. You can ring 07833 053749 or email us with the address and a few details.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
How experienced are you?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Does ELD work under paving or planting?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
What we look for on each type of roof
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Signs you need electronic leak detection in Charlwood
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
People usually book a survey after spotting one of these:
- Leaks through a covered membrane
- A flat roof leak that can’t be traced
- Gaps at membrane joints
- New membranes needing a check before handover
Take an older house close to Monkwood Mission Church: flat-roofed rear additions and dormers added over the years are worth checking.
What to check before booking
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- When you’ll get the report
- Is there a chance to talk the report through?
- Whether the price includes VAT

Checking the roof from ground level
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
