The survey, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes an hour or two for most homes, depending on how many separate roofs there are. A visit to Knebworth is planned like any other: the time, the access and where to park are agreed beforehand. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- We start with the property details and any concerns.
- A visit is booked for a weekday, Saturday or Sunday.
- Outside, we inspect from ground level, windows and other safe vantage points, and from the roof where safe.
- Inside, we check the roof space where there is safe access.
- You receive the report with photos and recommendations, prioritised by urgency.
Preparing for the visit
- Move anything stored under the loft hatch
- Let us know about parking before the day
- Jot down any questions you want answered
Arrange a survey
A quick phone call is typically the easiest start: call 07833 053749 or drop us an email and we will ask a few questions about the roof. You’ll have a price before anything is arranged.

Roof survey in Knebworth
Three packages cover most roofs: a Basic Survey from £150, a Standard Survey from £250 and a Premium Survey from £400, all including VAT. The Basic Survey gives a visual inspection, photographs and written recommendations. The higher packages add more checks, such as moisture detection, a structural check, thermal imaging and a drone where it applies. Each one comes with a written report. We’re often asked to look into ponding, splits or blisters on flat roofs and worn lead at chimneys and abutments, on flat roofs, clay and concrete tiles and ridges, hips and valleys.
Trees around homes in smaller places like Knebworth drop leaves, twigs and moss onto roofs and into gutters. Blocked gutters overflow and soak the walls below, and moss holds water against tiles. It’s the kind of slow problem a roof report picks up early. Moss on the roof and weeds in the gutter are both easy to spot from ground level.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible.

Useful tips for Knebworth property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Clear the loft hatch area before we arrive
- Check the roof from ground level after storms
- Photograph stains when they appear
- Ask about a flat roof on an extension or garage too
The Premium Survey includes a 12-month follow-up. It shows how the roof has fared over the year, and whether work has done its job.
Keep the loft space ventilated. A stuffy loft collects condensation, and it can wet timbers and insulation. Make sure insulation does not block the airflow at the eaves.

Roof by roof
Concrete interlocking tiles
Many post-war houses have concrete interlocking tiles. They’re heavy and hard-wearing, but their surfaces weather over the years.
Chimney stacks
Our chimney check is a visual inspection of the stack, not a flue, gas or sweep inspection. We will tell you if the flue needs a specialist.
Local roofs in Knebworth
Knebworth House, about 1.3 miles north-west, is one of the historic houses in the wider area around Knebworth. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Whichever you have, the details that tend to fail before the covering itself get the closest look.
Take a building like Knebworth Primary and Nursery School: its roofs, gutters and any chimneys need the same checks as a house’s, just on a bigger scale. For landlords with property near Knebworth station, a roof report helps you deal with small faults before they turn into a call from a tenant.

Do you need a roof survey in Knebworth?
Not every roof problem comes from outside. Poor ventilation lets condensation build up in the loft, and the damp gets into timbers and insulation. It can look like a leak, and it needs a different fix.
A survey can pick up problems such as:
- Worn lead at chimneys and abutments
- Cracked or blistered flat roof coverings
- Torn or sagging underlay
- Worn or blocked valleys
If you live near a park like Knebworth Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall.
Questions to ask before you book
