Pre-purchase roof surveys for homes and businesses in Lea Valley
Our packages start with the Basic Survey from £150, with the Standard Survey from £250 and the Premium Survey from £400, all including VAT. Standard adds moisture detection, a structural check and a follow-up consultation. Premium adds thermal imaging, a drone inspection where it applies and an in-person consultation. Pick the one that fits the property. Every package comes with a written report, photos and recommendations. Common reasons to book are flashings that have lifted or split and damp timbers or stains in the loft, on flat-roofed extensions and dormers, clay and concrete tiles and the roof space.
Some older homes in villages like Lea Valley are listed or sit in a conservation area. If so, re-roofing in different materials may need consent, so check with the council before work starts. For a buyer or someone with a newly finished roof, it’s worth knowing which applies. England has around 10,000 conservation areas and about 500,000 listed buildings.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Do not leave it until just before exchange
- Give your solicitor a copy of the report
- Check we’ll be able to get into the loft space
- Mention any deadline when you get in touch
Your report arrives by email, with photos of what we found. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. Each defect is explained in plain words, with recommendations prioritised by urgency where relevant.
Chimneys and flashings need watching. Look for leaning pots, missing mortar and lifted lead. A pair of binoculars from the garden shows a lot.
Roof by roof
Chimney stacks
Leaning stacks, loose pots and eroded mortar are common findings. We photograph them so you can raise them before exchange.
Clay and concrete tiles
Tiled roofs often last half a century or longer. Cracked, slipped or missing tiles are noted, and for mismatched replacements that point to past repairs.
Buying a home or a new roof in Lea Valley
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new. Lea Valley is about 2 miles from the edge of the flight restriction zone around Luton Airport. If the drone is used for your survey, we check the exact boundary for the address before flying.

Letting agents can arrange access with tenants, at a time agreed in advance. Surveys run on any day of the week, which helps when tenants work during the week.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant.
The survey, step by step
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. The survey normally takes roughly 1–2 hours at the house you’re buying, depending on its size and how much of the roof can be seen. In a hamlet or village like Lea Valley, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- After your offer is agreed, you book and share your timetable.
- We arrange access with you, the agent or the seller, including the loft.
- We start outside, looking at the roof from the ground and from vantage points.
- We then look from upstairs windows and inside the loft where it’s safe.
- You get a written report with photos and recommendations before you exchange.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Keep pets out of the way during the survey
- Let us know about parking near the property
Book a survey
A quick phone call is normally the easiest start: call 07833 053749 or email us and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Advice
Do you need a pre-purchase roof survey in Lea Valley?
Flat roofs turn up on extensions, dormers, porches and garages. Felt flat roofs often last around 15 to 20 years, and ponding, blisters and splits are common signs of age. A buyer can easily miss them, especially when they’re only visible from an upper floor.
Signs worth acting on include:
- Gutters choked with leaves and moss
- Roof slopes that look uneven or sagging
- Damp timbers or stains in the loft
- Worn or lifted lead flashings
If you live in an older home near All Saints, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges.
Before you book any roof surveyor
- Whether the loft space is looked at, where there is one
- How long they’ve been surveying roofs
- Their report turnaround times
- Whether you can ask questions once you have the report
Why it is worth a survey now in Lea Valley
The lender’s valuation is done for the lender, not for you. Its job is to check the property’s value for the mortgage, and it will not look closely at the roof. Our survey is done for you. In a place like Lea Valley, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
Prices start from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we will tell you which fits.
What you get with us
- Thermal imaging and drones used where they help

Your questions about pre-purchase roof surveys in Lea Valley
Does a conservation area affect roof work in Lea Valley?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you cover smaller places like Lea Valley?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
When should I book a pre-purchase roof survey?
The sooner after your offer is accepted, the better. The report is most useful before exchange, because after that the roof is yours to deal with.
How soon is the report ready?
Premium reports arrive the same day, Standard reports within 24 to 48 hours and Basic within 48 hours. Reports are emailed, with photographs.
Can you inspect my roof with a drone?
Where it is applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
