Edgware roofs and the weather
With Headstone Manor about 3.9 miles south-west, Edgware sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Different coverings let water in at different points, which shapes where the search starts.
Anyone responsible for a site like Beit Shvidler Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. Homes near green spaces like Stoneyfields Park can get more leaves in their gutters in autumn.

About our roof leak investigation in Edgware
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us and so do photos. Even on a dry day, a leak usually leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. Common reasons to book are staining around the chimney inside and leaks at a dormer or roof window, across chimney stacks, lead flashings and rooflights and dormers.
Water getting into a London home often comes from a detail you can’t see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in Edgware, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what isn’t.

Signs you need a roof leak investigation in Edgware
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, while some very old roofs have nothing under the coverings. On slate roofs, slipping is often caused by corroded nails.
Problems we come across often include:
- Damp underlay across a wide area
- Water that shows only in certain storms
- Ceiling stains that grow after rain
- Damp ceilings under a flat roof
For businesses in and around places such as Broadwalk Centre, a quick answer on where water is coming in keeps a business running.
What to check before booking
- Which parts of the roof they’ll actually see
- What the survey won’t cover
- Their track record with similar roofs
- What exactly goes into their report
What happens on the day
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take about one to two hours, more where the leak is intermittent or the roof is large. Surveys in Edgware can be booked for any day of the week. 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 pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Check pets are kept safely away
- Have any paperwork from past roof work to hand
- Leave a clear route to the loft
Getting a price
Booking is simple: just phone 07833 053749 or use the contact form, let us know about the property and we’ll suggest the right survey. The price is agreed up front.

How we price roof leak investigations
We confirm the price for the job before booking. This is what makes a difference:
- Roof area
- House, block, shop or office
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 inc. VAT. We can help you choose the package that fits what you need to know.
Booking your survey
To price your survey accurately, we’ll ask about:
- When you need the report by
- Pictures from the garden or a window, if you have them
- The type of building and roof, such as pitched or flat
- Whether there’s a loft hatch, a shared roof or tricky access
Unsure which package suits your roof? It’s easiest to phone 07833 053749 or drop us an email and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.
Why get it checked now?
Water damage grows the longer it is left. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. In Edgware, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Roof leak investigation starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

Your questions about roof leak investigations in Edgware
Do you cover Edgware?
Yes, Edgware is within the area we cover. Our area covers London and the South East. You can call 07833 053749 or drop us an email with the address and some details.
Is parking a problem for a survey in Edgware?
It can be, so it is useful to let us know about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
How long does a roof leak investigation take?
On site, it normally takes between one and two hours for most houses, and more on a big or complicated roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Will you check the loft?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
Is it a leak or condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern, take moisture readings and tell you which is more likely.
Will you fix the leak as part of this?
A leak investigation finds and reports the likely source. The repair itself is a separate job. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.

Useful tips for Edgware property owners
These tips come from what we see on roofs every week:
- Mention any plumbing above the damp area
- Catch drips in a bucket and protect the floor
- Stay off ladders and the roof
- Make sure the loft is accessible
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. It is a chance to ask about anything in the report.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
