FAQs for Underhill
Is my home in Underhill listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you survey roofs for landlords with property near New Barnet station?
Yes, landlords and agents are among the people we work for. Just call 07833 053749 or use the contact form with the details.
Our stack is shared. Can you still survey it?
Yes. Shared stacks are common on terraced and semi-detached houses. We survey what we can see safely, and note anything that seems to involve next door.
Do you work in Underhill?
Yes. Our area covers London and South East England, and that includes Underhill.
How do you inspect a chimney without scaffolding?
We use safe viewpoints rather than climbing onto the stack. A drone inspection is part of the Premium Survey where applicable. Any area we couldn’t view is noted.
How fast do I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime. Let us know your preferred days as you book.
Chimney surveys for homes and businesses in Underhill
A leaning chimney stack is worth having looked at. A stack may lean because the mortar on one side has weakened, which can happen over many years of use. The survey notes how the stack looks, how far it seems to lean and the state of the bricks and joints. Where it may be a structural concern, we’ll recommend a structural engineer. If you are worried about flaunching that has broken away and bricks with flaking faces, a survey will tell you what’s going on, on chimney breasts, lead flashings and flaunching alike.
A London butterfly roof slopes down to a central valley gutter that drains to the back of the house. Hidden behind the parapet, that gutter can block or split without anyone seeing it. For a house in Underhill with this kind of roof, the hidden gutter is one of the first things to check.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

- How tall the building is and how easy the roof is to see

Underhill homes and their roofs
Historic houses like Wyllyotts Manor, about 3.4 miles north, show how far back building in the area around Underhill goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Each of these coverings has its own weak points, from fixings and valleys to flashings, chimneys and gutters.
Homes near green spaces such as Highlands Gardens can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. If you run a business near Spires Shopping Centre, knowing the roof’s condition lets you budget for work rather than pay for emergencies. The streets around a church such as St John the Baptist Church are frequently among the oldest in a place, and if your house is among the older ones nearby, corroded nails, tired lead and weathered chimney pointing are the things to watch on older roofs.

What we look for on each type of roof
Chimney breasts and the loft
If a chimney breast has been removed below, we note what we can see of the support above. Confirming the support is a job for a structural engineer.
Lead flashings
Mortar fillets are sometimes used where lead would typically be. They tend to crack, so we check them closely.

Tips that help
There’s plenty you can do without going near the roof. Here’s what helps most:
- Remove aerials or dishes from the stack if they’re no longer needed
- Use a Gas Safe registered engineer for gas appliances
- Ask for ventilated caps on redundant stacks
- Check your stacks from ground level after strong winds
After the visit, we write up the report with photographs of each stack. It explains the condition of each part of the stack and any damp inside. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Check redundant flues are capped with ventilation. Ventilation helps keep the stack dry.
Rented homes, blocks and businesses
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the visit with that in mind.
We survey roofs for landlords and letting agents as well as householders. The report gives you a dated record of the chimney stack, with photographs, which helps you plan work between tenancies.
How the survey works
Once we’ve finished looking, we write up our findings as a report with photographs, emailed to you. As for time on site, it typically takes between one and two hours at most homes, and more on a big or complicated roof. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Underhill moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- We start with the details: how many stacks, whether any are shared and any signs of damp.
- We inspect each stack from safe viewpoints outside.
- Every part we can see is looked at: pots, cowls, flaunching, pointing, bricks and flashings.
- We check the chimney breasts and the stack in the loft space where we can reach them.
- The findings are written up with photos and recommendations and emailed to you.
Getting ready for the survey
- Note where any stains or damp appear
- Have keys ready for side gates, garages or roof access doors
- Keep pets inside or away from the areas we’re looking at
Booking a survey
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.
Advice
DIY checks: what’s safe
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
