What we are asked to look at in Westcott
Some water in the loft is not rain at all. Warm, moist air from the house rises into a cold roof space and condenses, especially where ventilation is poor. Drips from nails and damp underlay are typical signs.
Common reasons to book include:
- Drips in the loft during heavy rain
- Ceiling stains that grow after rain
- Damp underlay across a wide area
- Damp on a chimney breast
Trees in and around Milton Heath and The Nower shed leaves that can end up in nearby gutters.

How a roof leak investigation works in Westcott
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. Each of these is checked in turn and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. We look at all of them, from each safe vantage point. If you’ve noticed wet patches high on an inside wall and water marks that spread in wet weather, we can find out what’s behind it, whatever the roof.
Many homes in small places like Westcott face open ground, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photo. It records what’s sound as well as what is not.

How the survey works
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely, using the ground, windows, the loft and a drone where it applies. Most surveys take an hour or two at most homes, or half a day or so for a commercial building. Somewhere as small as Westcott, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- Move anything stored under the loft hatch
- Let us know about parking near the property
- Leave side gates unlocked
How to book
Not sure which survey you need? The easiest way is to phone 07833 053749 or send us an email and describe the roof and why you want it surveyed. We will talk you through the options and what they cost.
Advice
Landlords, agents and block managers in Westcott
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps when budgeting.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it when booking and we’ll plan the survey around it.
Practical tips
Most of what helps is simple and safe from the ground. A few suggestions:
- Keep a photo record of the damp patch
- Clear the loft hatch so we can get in
- Mention earlier attempts to fix the leak
- Record whether it leaks in every downpour or only some
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Keep the loft space ventilated. Air movement keeps condensation down, and condensation is a common false alarm. Keep insulation clear of the eaves.
What you can safely check yourself
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.

What we cannot see
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks that only appear in weather we can’t recreate
- Structural calculations (that is a structural engineer’s job)
- Carrying out the fix

Roof leak investigations around Westcott
About 2.2 miles north lies Polesden Lacey, a reminder of how long the area around Westcott has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
Anyone responsible for a site like Surrey Hills All Saints Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. If you live in an older home near St John's Community Hall, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
