Cranleigh questions
Do you cover Cranleigh?
We do. The survey and report are the same in Cranleigh as anywhere else.
Is Cranleigh within the area you cover?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years, with 98% customer satisfaction.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Can you always find the source?
We cannot promise to find every leak on one visit. Most leave clues we can follow, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Roof leak investigations for homes and businesses in Cranleigh
Some ‘leaks’ aren’t leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, leaving marks that look just like rainwater. Telling the two apart matters, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. We survey lead flashings, valleys and parapet gutters and the roof space, and people most often book us about wet patches on loft insulation and condensation that looks like a leak.
In older homes around places like Cranleigh, the underlay may be old bitumen felt, or there may be none at all. Once the slates or tiles let water past, there’s little to stop it reaching the ceiling. Finding where it gets in, and whether it is old wear or new damage, decides what comes next. In the loft, damp battens or wet insulation are often the first clues.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Prices for roof leak investigations in Cranleigh
A few things affect what a survey costs:
- Commercial roofs and larger buildings
- Extra roofs, like extensions, dormers or garages
- The package you choose: Basic, Standard or Premium
- The shape of the roof and its details
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
What we need to know
You don’t need to know any roofing terms. Just tell us:
- Anything about access we should know
- Any photos you have, taken from ground level or a window
- What’s prompted the survey
- The address and postcode of the property
We confirm the price for your roof before booking, so you know where you stand. Roof leak investigation starts from £150, including VAT. To book, phone 07833 053749 or drop us an email.
How the survey works
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take an hour or two for most homes, though a hard-to-trace leak can take longer. With a bit of garden around a house, as there often is around Cranleigh, the roof can be viewed from several angles. Mention any side of the property we cannot get to. Inside, the loft is checked where it can be reached safely.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
How to prepare
- Leave a clear route to the loft
- Make a note of anything you’d like us to look at
- For a flat or shared roof, check access with the building owner or managing agent

Other services in Cranleigh
Do you need a roof leak investigation in Cranleigh?
Condensation is often mistaken for a leak. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly in lofts with blocked eaves. Wet nail tips and damp underlay over a wide area are classic signs.
Typical things we are asked to look at include:
- Damp ceilings under a flat roof
- Damp on a chimney breast
- Stains around a skylight
- Staining where a gutter or parapet meets the wall
If your home is one of the older ones in the streets near Church of St Nicholas, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Questions to ask before you book
- How they plan to inspect the roof safely
- What happens after the report arrives
- What’s outside the scope of the survey
- Will they check the loft as well as the outside?
Wind, rain and roofs in Cranleigh
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Different coverings let water in at different points, which shapes where the search starts.
Living close to Sayer's Croft LNR is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall. Anyone responsible for a site like St Cuthbert Mayne Catholic Primary School will know that a leak through a large roof is often found some distance from where the water shows inside.

Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Note the weather when the leak shows
- Take dated photos of the leak
- Leave roof access to professionals
- Have an electrician check any wet fittings
If the leak turns out to be condensation, the report says so, and suggest how the roof space could be better ventilated. That avoids roof work that wouldn’t help.
Look at the roof from ground level after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which can make access easier.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
