Do you need a roof leak investigation in Graveley?
When a slate slips or a tile cracks, the underlay takes the water. Old bitumen felt may cope for a while, but it tears and sags with age, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
People typically book a survey after spotting one of these:
- Water dripping from rafters or underlay
- Water marks that spread in wet weather
- Stains around a skylight
- Damp on a chimney breast
Anyone responsible for a site like Graveley Primary School will know that a leak through a large roof is often found some distance from where the water shows inside.
Before booking anyone
- What the survey will not cover
- Whether the inside of the roof is included
- What exactly goes into their report
- What experience they bring
About our roof leak investigation in Graveley
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. It gives any roofer a clear brief. We find and report the source, while the repair is a separate matter. If you’ve noticed damp patches next to the stack and water coming in around a roof light or dormer, we can find out what’s behind it, on chimney stacks, valleys and parapet gutters and lead flashings alike.
Being in a small place like Graveley makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. It’s useful to know where the water appears, in what weather, and what you’ve seen outside, along with any repairs done before. Photos of the stain and of the roof from outside are helpful too.
The written findings come by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Graveley questions
Does a conservation area affect roof work in Graveley?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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 Graveley in the area you cover?
Yes, Graveley is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or send us an email and let us know about the property.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Is there anything I need to do before the visit?
Check the loft can be reached. Have any photos of the leak ready, and let us know about past repairs. Keep catching drips and keep water away from electrics.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
When does the report arrive?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.

How it works
Once we have finished looking, we write up our findings in a report with photographs. As for time on site, most surveys take roughly 1–2 hours, more where the leak is intermittent or the roof is large. Older rural homes like those around Graveley can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- Keep pets in another room
- Leave a clear route to the loft
- Dig out any old roof reports or invoices

Leave it or get it looked at?
A leak near lights or wiring needs attention quickly. Keep away from any fitting that water is reaching. Finding where the water is getting in should follow right away. Older cottages and farmhouses around Graveley can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Our price is from £150, including VAT.

Roof leak investigations around Graveley
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Different coverings let water in at different points, which shapes where the search starts. The wider area around Graveley has a long history of building, with Knebworth House about 4.4 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Take an older house close to Church of St Mary: lead flashings, valleys and old chimneys are typical places for water to get in. If you own a rental within reach of Stevenage station, a clear finding on where water gets in helps you brief a roofer straight away.

Useful tips for Graveley property owners
Over many surveys, some simple habits stand out:
- Do not touch fittings that water is reaching
- Move stored items away from the hatch
- Tell us if there are tanks or pipes in the loft
- Protect furniture and flooring under the leak
Your report arrives by email, with photographs of what we found. It sets out where we believe the water is getting in, how it’s travelling and what needs attention. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Keep gutters, valleys and outlets clear, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
