Roof survey in Lemsford
There is no single reason to have a roof surveyed. Some have spotted a stain or a slipped slate, while others just want to know where they stand. The approach is the same in each case: we inspect carefully and explain what we see in writing. We survey on weekdays and at weekends, so finding a time is rarely difficult. We survey lead flashings, ridges, hips and valleys and natural slate, and people most often book us about ponding, splits or blisters on flat roofs and loose ridge or hip tiles.
Some older homes in villages like Lemsford are listed or in a conservation area. If yours is, re-roofing in different materials may need consent, so the council is the place to check. Knowing the roof’s condition helps you plan ahead with that in mind. Where a building is listed, matching the existing roof materials is frequently expected.
What you get is a clear record of the roof on the day we saw it. It is useful right away, and a good reference for later, like when you want to compare after future work.

Practical tips
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Leave roof access to professionals
- Move stored items away from the loft hatch
- Look for debris in the garden after high winds
- File the report with your home documents
File the report with your other home documents. It gives you something to compare against later, and it can help when you sell.
After a storm, check the roof from the garden and the street. Fragments of slate or tile on the ground mean something has shifted. Prompt repairs stop small problems growing.
What a survey costs
We confirm the price for the job before booking. These are the things that affect it:
- How complicated the roof is, with its valleys, chimneys and parapets
- The size of the roof
- Which survey package you book
- The height of the building and how the roof can safely be seen
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, it’s useful to mention:
- The style of property, from a terrace to a block
- Your postcode, so we can check access and travel
- Dates you’re working to, such as exchange
- What made you get in touch
A quick phone call is typically the easiest start: phone 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
What a roof survey looks like in Lemsford
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them.
Landlords with a home close to Welwyn Garden City station may find that a dated record of the roof is useful when planning maintenance across a let. The streets around a church like Church of St John the Evangelist are often among the oldest in a place, and if you own one of the older houses nearby, old fixings, lead flashings and tall chimneys are typical of older roofs.

Lemsford questions
How do I find out if my home in Lemsford is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Can a landlord with a rental near Welwyn Garden City station book a roof survey?
Yes, rented property is part of what we cover. Just ring 07833 053749 or send us an email and tell us about the building.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Let us know about it when booking and we will plan the survey around it.
Do you look in the loft space?
If there is a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
Do you carry out asbestos surveys?
No. Asbestos was banned in UK construction in 1999, so older buildings may have it. Our report notes any materials that might, and recommends a specialist asbestos surveyor looks at them.
Can you look at a roof that is joined to next door?
Yes, the part you own or can give access to. Next door’s roof is only inspected as far as we can see it. Shared chimneys and party-wall upstands are checked from your side.
Signs you need a roof survey in Lemsford
Slates and tiles frequently outlast the fixings that hold them. On slate roofs, corroded nails let slates slip, which is known as ‘nail fatigue’. On tiled roofs, battens and pegs can rot, letting tiles move.
Problems we come across frequently include:
- Leaning or weathered chimney stacks
- Worn lead at chimneys and abutments
- Worn or blocked valleys
- Water stains on rafters and ceiling joists
With Digswell House about 1.9 miles north-east, the area around Lemsford has a long history. On a period home nearby, the survey separates sound original work from tired later repairs.
Questions to ask before booking
- Their track record with similar roofs
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID

How the survey works
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where it applies. The survey usually takes about 1–2 hours for an ordinary house roof, and longer if there are extensions, dormers or several chimneys. Rural addresses near Lemsford can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start by hearing what you’d like checked and why.
- We arrange a day that suits you, including weekends.
- We inspect from ground level, from windows, from the loft space and from the roof where safe.
- Slates or tiles, ridges, hips, valleys, flashings, chimneys and gutters are all examined and photographed.
- Your report arrives by email, with recommendations prioritised by urgency.
Getting ready for the survey
