Roof leak investigation in Hayes, Greater London

Roof leak investigation in Hayes: what you get

We use moisture detection and thermal imaging where they help. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. Thermal imaging works best after a sunny day, on a dry roof with little wind. Typical surveys look at damp patches next to the stack and ceiling stains that grow after rain, across rooflights and dormers, slate and tile slopes and valleys and parapet gutters.

Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Insurers typically exclude wear and tear, so it helps to know whether damage is old or new. A careful look in Hayes tells the two apart where the evidence allows. A written record with photos helps you explain what was found to whoever deals with it next.

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 photograph where possible.

What happens on the day

The aim of the visit is simple: to see as much of the leaking roof as can be seen safely and record it clearly. Notes and photos go into the written report. The visit typically takes about one to two hours, more where the leak is intermittent or the roof is large. In Hayes, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.

1. You tell us where the water appears, when, and what the weather was doing.
2. Inside, we look at the stain and the ceiling around it.
3. From the roof space, we trace the water’s route where there is safe access.
4. We inspect the likely entry points outside, from ground level, windows and the roof where safe.
5. You receive a report with the likely source, photos and recommendations.

What affects the price in Hayes

When we price a survey, we consider:

• Building height and the viewpoints available
• The type of building, from a house to a block or an office
• Extensions, dormers and garages with roofs of their own
• Which survey package you book

Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.

Helping us price your survey

There’s no need for technical words. It’s enough to let us know:

• Where water is showing inside, if it is
• Dates you’re working to, such as exchange
• Any photos you have, taken from ground level or a window
• Your postcode, so we can check access and travel

We survey roofs on weekdays and at weekends. To find a date that works for you, phone 07833 053749 or email us with the address and the days you’d prefer.
