Flat roof survey in Letchmore Heath: what you get
Standing water is one of the first things we look for on a flat roof. It can point to poor falls, a blocked outlet or a deck that is deflecting. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. If you’re worried about raised blisters across the surface and outlets that hold water back, a survey will tell you what’s going on, on EPDM rubber, mastic asphalt and single-ply membranes alike.
Some older homes in villages like Letchmore Heath are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Useful tips for Letchmore Heath property owners
Over many surveys, some simple habits stand out:
- Clear roof outlets and gutters each autumn
- Check from a window for ponding after heavy rain
- Note any new marks on ceilings beneath the roof
- File the paperwork for the roof and any repairs
Questions about the findings are always welcome. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, giving you a chance to go through what we found.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.
Flat roof surveys around Letchmore Heath
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. High Elms Manor, about 3.5 miles north-west, is one of the historic houses in the wider area around Letchmore Heath. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Radlett station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like Fair Field Junior School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you look after a shop, office or commercial unit, for instance near Harlequin Centre, a flat roof over a business is out of sight and out of mind until it leaks.

FAQs for Letchmore Heath
How do I find out if my home in Letchmore Heath is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Letchmore Heath in the area you cover?
Yes, Letchmore Heath is within the area we cover. Our area covers London and South East England. Just phone 07833 053749 or drop us an email and tell us about the property.
What happens after the survey?
You’ll get the report by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
What insurance do you have?
We are covered by professional indemnity and public liability insurance.
Will the survey show why my flat roof is leaking?
The survey covers the covering and all the details where leaks normally begin, recording anything that could let water through. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. We will talk about access as you book.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
When you need someone else
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- A structural engineer’s assessment of the deck
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- A promise that the roof won’t leak in future
If you are not sure which survey you need, ring 07833 053749 or drop us an email and we will give you a straight answer. The full list of what we check.
What we look at
- Mastic asphalt
- Upstands and outlets
- GRP fibreglass
- Felt flat roofs
- Single-ply membranes
- EPDM rubber
What we do, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. Most visits take about 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. Somewhere as small as Letchmore Heath, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You let us know about the roof, its covering if you know it, and any leaks.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Inside, we look for damp and staining under the roof where there’s access.
- We send a written report with photos, the defects we found and what we recommend.
How to prepare
- Have any questions written down, so nothing gets missed
- Keep pets out of the way during the survey
- Find any records of previous roof work

DIY checks: what’s safe
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
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.
