Letchworth Garden City: your questions answered
Is there anything to prepare before you come to Letchworth Garden City?
It helps to clear access to the loft, and to let us know about leaks, damp patches or recent work. Parking and access details for Letchworth Garden City help us plan the visit.
Does a conservation area affect roof work in Letchworth Garden City?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Will you check the loft?
Usually, if there is one and it can be reached safely. The roof space can show things the outside can’t, such as damp timbers, staining or daylight.
Do you look for flat roof leaks?
The survey covers the covering and all the details where leaks typically begin, and photograph anything that could be letting water in. Where the source is not obvious, a roof leak investigation or electronic leak detection may be the next step.
How much is a survey?
Prices start from £150, including VAT. You will know the price for the job before booking, and it depends on the roof’s size, access and the package you choose. For a price, call 07833 053749 or drop us an email.
How a flat roof survey works in Letchworth Garden City
Ponding is frequently the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we will recommend a structural engineer. Typical surveys look at edge trims that have lifted or split and upstands pulling away from walls, on upstands and outlets, EPDM rubber and GRP fibreglass.
Houses around a town like Letchworth Garden City often have a flat roof somewhere, over an extension, garage, porch or dormer. Older ones are often felt, which frequently lasts around 15–20 years, while newer ones may be EPDM rubber or GRP fibreglass. Ponding water, splits along the edges and lifting upstands are the usual warning signs. Standing water days after rain often shows a flat roof needs attention.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

DIY checks: what’s safe
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Flat roof surveys in Letchworth Garden City: local notes
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Letchworth Garden City is one of England’s garden cities, planned in the early twentieth century. The original garden city houses are now more than a century old, alongside later estates. On the oldest homes, nails, battens and underlay may have reached the end of their life even where the tiles look sound.
With Hinxworth Place about 4.6 miles north, the area around Letchworth Garden City has a long history. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. If you live in an older home near St Michael, flat-roofed rear additions and dormers added over the years are worth checking.

What a flat roof survey does not cover

- Asbestos testing, which needs a specialist asbestos surveyor
- The condition of the deck or insulation hidden under the covering
- A structural engineer’s assessment of the deck

- GRP fibreglass
- Mastic asphalt
- Felt flat roofs
- EPDM rubber
- Single-ply membranes

Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Ask contractors to protect the roof if they work on it
- File the paperwork for the roof and any repairs
- Look for standing water a day after rain
- Make sure new fixings through the roof are properly sealed
After the visit, we write up the report with photographs of what we found. It covers the type of covering, its condition and each defect, with our recommendations. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Book a survey every few years, and again after new fixings, units or rooflights go in. You’ll spot changes early and have a record to look back on.

Do you need a flat roof survey in Letchworth Garden City?
A flat roof lies open to sun, rain and frost, and water drains off it slowly. Over the years, coverings harden, crack and start to come away at the edges. People normally call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
Problems we come across often include:
- Water getting in at rooflights
- Loose or cracked edge trims
- Blocked or damaged outlets
- Raised blisters across the surface
For landlords with property near Letchworth Garden City station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
