Roof leak investigations for homes and businesses in Grahame Park
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. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. We survey valleys and parapet gutters, the roof space and lead flashings, and the problems we’re asked to look at most are leaks at a dormer or roof window and leaks that appear only in driving rain.
London’s Victorian and Edwardian roofs have frequently been repaired many times. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. That’s as true in Grahame Park as anywhere in London. A written record with photos helps you explain what was found to whoever deals with it next.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

How we price roof leak investigations
When we price a survey, we consider:
- The type of building, from a house to a block or an office
- The shape of the roof and its details
- How big the roof is
- Which survey package you book
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
What to let us know when you get in touch
Here’s what helps us most when you get in touch:
- When you need the report by
- Why you want a survey: buying, a leak, a storm or new work
- Pictures of the roof from a safe spot, if you have them
- What kind of property and roof it is
A quick phone call is normally the easiest start: ring 07833 053749 or send us an email. The price is agreed before a date is set.
Tips from our surveys
A little preparation and a few simple habits help. Our tips:
- Write down the wind direction and rain when it leaks
- Tell us about any past repairs to the roof
- Catch drips in a bucket and protect the floor
- Keep a photo record of the damp patch
We email the report to you. It sets out where we believe the water is getting in, how it is travelling and what needs attention. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.

Why act early in Grahame Park
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. Any roof job in Grahame Park means planning around parking, neighbours and access. That’s a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
Prices start from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT, and we’ll tell you which fits.

Questions from Grahame Park
Do you carry out roof surveys in Grahame Park?
Yes, Grahame Park is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or email us with the address and some details.
How do I find out if my home in Grahame Park is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Why isn’t the leak directly above the stain?
Water rarely drops straight down. It runs along rafters, battens or underlay before it drips, so the entry point is often well away from the mark. We follow the route back instead of guessing.
Can a leak be traced on a dry day?
Often, yes. Stains, tide marks, damp timbers and moisture readings normally point the way. Intermittent leaks can be harder, so your photos and notes from wet days are very useful.
Does the report include photographs?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
Will you fly a drone over my roof?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Roof leak investigations around Grahame Park
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Knowing the roof type helps narrow down where water may be getting in. The wider area around Grahame Park has a long history of building, with Heath Hall about 3.5 miles south-east. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you live near a park such as Sunny Hill Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall. If you look after a shop, office or commercial unit, for instance near Broadwalk Centre, a leak can close part of a shop or office, so finding the cause quickly matters. If you own a rental within reach of Mill Hill Broadway station, a clear finding on where water gets in helps you brief a roofer right away.

How the survey works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from each safe vantage point, photograph what we find and make notes for the report. Most visits take an hour or two for a house; commercial roofs usually need 3–4 hours. In Grahame Park, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it is useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You let us know where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Point out any leaks or damp patches
- If the roof is shared, arrange access with whoever manages the building
- Tell us where we can park nearby

Related advice
Checking the roof from ground level
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Different roofs, different checks
Chimney stacks
A stack has several possible ways in for rain. Each is looked at from every safe viewpoint, and look for damp on the breast inside.
Lead flashings
Some roofs have mortar where you’d expect lead. They crack as the roof and wall move, letting rain run behind the joint.
