Roof leak investigations for homes and businesses in Nash
Most roof leaks start at a joint rather than the middle of a slope. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. Each one is looked at from wherever it is safe to see it. Typical surveys look at water marks that spread in wet weather and damp underlay across a wide area, on valleys and parapet gutters, chimney stacks and flat roof details.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Nash, we inspect what we can reach safely and are given access to. It helps to know when the water appears and in what weather.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Questions from Nash
How do I find out if my home in Nash is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 carry out roof surveys in Nash?
Yes. Our area covers London and the South East, and Nash is part of that. Just ring 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Is there anything I need to do before the visit?
Note when the leak appears and what the weather was doing. Clear access to the loft. Keep away from any light or socket that water is reaching.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
Is this a RICS survey?
No. We check the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance.
What we are asked to look at in Nash
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
These are some of the problems a survey can pick up:
- Staining where a gutter or parapet meets the wall
- Water marks that spread in wet weather
- Condensation that looks like a leak
- A leak that comes and goes with the weather
Trees in and around Coney Hall Recreation Ground shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching.
What to check before booking

- What experience they bring

How the survey changes by roof type
Lead flashings
Mortar fillets are sometimes used instead of lead. Fillets crack and pull away over time, letting rain run behind the joint.
Chimney stacks
Our chimney check is a visual inspection of the stack, not a flue, gas or sweep inspection.
Before and after the survey
Most of what helps is simple and safe from the ground. Our suggestions:
- Don’t climb onto the roof to look
- Mention earlier attempts to fix the leak
- Tell us if there are tanks or pipes in the loft
- Don’t touch fittings that water is reaching
Keep the report after the work is done. If water appears again, it shows what was found before, which makes the next step quicker.
Keep the loft space ventilated. Air movement keeps condensation down, which is frequently mistaken for a leak. Check insulation doesn’t block airflow at the eaves.
Rented homes, blocks and businesses
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
Wind, rain and roofs in Nash
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Historic houses such as Down House, about 2.4 miles south-east, show how far back building in the area around Nash goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you own a rental within reach of Hayes (Kent) station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. If you run a business near The Mall, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.

Why it’s worth a survey now in Nash
A small drip today can be a bigger leak after the next storm. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. London’s older roofs frequently have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
Prices start from £150, with VAT included, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before you book.

What else we do in Nash
How the survey works
We’ll ask a few questions first, such as when any problem began and what work has been done before. The inspection then takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. In Nash, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Keep pets in another room
- Let us know where we can park nearby
