What we look for on each type of roof

Valleys

A valley takes the rain from both sides of the roof. Split lead, cracked linings or slipped tiles let water in.

Slate and tile slopes

On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.

Roof leak investigation in Petersham: what you get

Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. Common reasons to book are drips in the loft during heavy rain and leaks at a dormer or roof window, across the roof space, valleys and parapet gutters and slate and tile slopes.

In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Petersham, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.

Where we cannot see part of the leaking roof, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

What happens if roof problems are left?

Damp loft insulation loses much of its value. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.

Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

What a roof leak investigation looks like in Petersham

Historic houses like Pembroke Lodge, about 0.5 miles south-east, show how far back building in the area around Petersham goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. 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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. The covering and its details give the first clues when tracing where water is coming from.

Anyone responsible for a site like The Russell Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. For an older house near a landmark such as St Peter's Church, lead flashings, valleys and old chimneys are typical places for water to get in. Homes near green spaces like Marble Hill Park can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall.

Checking the roof from ground level

The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where applicable.

You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.

Petersham: your questions answered

Do you carry out roof surveys in Petersham?

Yes, Petersham is one of the places we work. The survey and report are the same in Petersham as anywhere else, and visits run on weekdays and weekends.

How do I find out if my home in Petersham is listed?

The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.

Is it the same as a RICS Level 2 or Level 3 survey?

No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.

How long have you been surveying roofs?

More than 5,000 surveys over 20+ years, across London and South East England.

Do you survey roofs on blocks of flats?

Yes, once whoever controls the roof agrees access. We check the parts we are given access to, and the report makes that clear.

Do you test for asbestos?

No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.

Do you carry professional indemnity insurance?

We hold professional indemnity and public liability insurance.

What affects the cost of roof leak investigations

When we price a survey, we consider:

  • The use of thermal imaging or a drone
  • How complicated the roof is, with its valleys, chimneys and parapets
  • Whether it is a home or a commercial building
  • Roof area

To find out what your survey will cost, ring 07833 053749 or use the contact form with the address and some details. We will confirm the figure before booking.

What to let us know when you contact us

If you can, have these to hand when you contact us:

  • Your timetable, like an exchange date
  • Pictures of the roof from a safe spot, if you have them
  • Anything about access we should know
  • The reason for the survey, such as buying, a leak or storm damage

We confirm the price for your survey before booking, so you know the cost up front. Roof leak investigation starts from £150, including VAT. For a price for your roof, phone 07833 053749 or use the contact form.

Tips from our surveys

There’s plenty you can do without going near the roof. Here’s what helps most:

  • Do not touch fittings that water is reaching
  • Leave roof access to professionals
  • Take dated photos of the leak
  • Let us know about any past repairs to the roof

If condensation is the cause, we explain it, with recommendations on ventilation. It saves chasing a leak that is not there.

After a downpour, look in the roof space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Photograph anything new.

How the survey works

It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take an hour or two, more where the leak is intermittent or the roof is large. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us when you book.

  1. We help you choose the package that suits the leak.
  2. We agree a date, including weekends.
  3. We inspect inside and out, starting from the stain.
  4. Where it is useful and included, we take moisture readings and use thermal imaging.
  5. The report explains the likely entry point and what needs attention.

Getting ready for the survey

  • If it is not your property yet, arrange access through the agent
  • Check we can get to the back of the property
  • Jot down any questions you want answered

Arrange a survey

Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.
