Westwick Row Roof Leak Investigation
Know where you stand with the leaking roof before you decide what to do next. We carry out roof leak investigations in Westwick Row, with photographs and a clear written report.
- Wet patches on loft insulation
- Leaks below a flat extension roof
- Water that shows only in certain storms
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Let us know what has already been tried
- Record whether it leaks in every downpour or only some
- Make sure the loft is accessible
- Keep water away from lights and sockets
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, so the repair is aimed at the cause.
Keep the roof space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Make sure insulation does not block airflow at the eaves.
Roof leak investigations for homes and businesses in Westwick Row
Older homes have more places for water to get in. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. Parapet walls and their gutters are looked at from wherever it’s safe. The findings are recorded with photos. We’re frequently asked to look into ceiling stains that grow after rain and damp ceilings under a flat roof, across chimney stacks, flat roof details and lead flashings.
Many homes in small places like Westwick Row face open ground, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Roof by roof
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
How it works
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. The survey itself takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. Older roofs in small places like Westwick Row can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Point out any leaks or damp patches

Checking the roof from the ground

Westwick Row: your questions answered
Is my home in Westwick Row listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you cover smaller places like Westwick Row?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Will you fix the leak as part of this?
This service finds and reports the cause, not to carry out the repair. The report gives any roofer a clear brief.
How experienced are you?
More than 5,000 surveys over 20+ years.
Will you definitely find the leak?
Not every leak can be pinned down in a single visit. Many leave clear signs, but some only appear in certain weather. We report what we found and the likeliest sources.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Honest limits
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Plumbing leaks that look like roof leaks
- Carrying out the fix
- A promise to find every leak on a single visit
If in doubt, ring 07833 053749 or use the contact form and we will point you to the right survey before you book. The full list of what we check.

Westwick Row roofs and the weather
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. The covering and its details give the first clues when tracing where water is coming from. Hemel Hempstead, which Westwick Row is part of, is one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points.
For businesses in and around places such as Village Arcade St Albans, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. Historic houses such as Batchwood Hall, about 3.1 miles north-east, show how far back building around Westwick Row goes. Older roofs around here can leak at old repairs as readily as at original details. Take an older house close to Church of Holy Trinity: the leak may come from a chimney, a valley or tired lead rather than the covering itself.
