How a flat roof survey works in Nag's Head
If the house you are buying has a flat roof on an extension, dormer or garage, it is worth knowing its condition before exchange. Felt roofs often last around 15 to 20 years, while EPDM and GRP often last longer. We set out the type of covering, its condition and the defects we found, with a photo of every defect. That gives you facts to raise with the seller or agent. If you’re worried about splits, cracks and crazing and leaks around rooflights, we can find out what’s behind it, on upstands and outlets, felt flat roofs and GRP fibreglass alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Nag's Head, the flat roof is often a shared part of the building.
What you get is a clear record of the flat roof on the day we saw it. It’s useful right away, and a good reference for later.

Your questions about flat roof surveys in Nag's Head
Do you carry out roof surveys in Nag's Head?
Yes, Nag's Head is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my home in Nag's Head listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How long will you be at the property?
Expect it to take between one and two hours on an ordinary house, though large, tall or awkward roofs take more time. The written report follows by email.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We can only inspect what we’re given access to.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible.
Will you walk on the flat roof?
Only where it’s safe to do so. If not, we use safe viewpoints and look inside, and the report says if any part couldn’t be seen. Fragile surfaces are never walked on.
Surveys for landlords and agents in Nag's Head
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out with the most urgent first where relevant, which helps with budgets and planning.
Where a roof is shared: we need access agreed with whoever owns or manages the building. Tell us about it when booking and we’ll plan the visit with that in mind.
What we look for on each type of roof
Rooflights and upstands
Where a flat roof meets a wall, the upstand has to stay sealed as the building moves. We look for splits, gaps and failed flashings over the top.
EPDM rubber
Rubber roofs can shrink back from their edges or lift where the adhesive has failed. Any we find are noted and photographed.
DIY checks: what’s safe
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
How it works
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely. The survey typically takes about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a London area like Nag's Head, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can be seen safely from ground level, windows, the loft and, where it is safe, the roof itself.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there is access.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Preparing for the visit
- Point out any leaks or damp patches
- If the roof is shared, arrange access with whoever manages the building
- Find any records of previous roof work
Book a survey
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you are ready.

What a flat roof survey looks like in Nag's Head
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. The wider area around Nag's Head has a long history of building, with Witanhurst about 1.7 miles north-west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Shop and office owners around Brunswick Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after. For site and facilities teams at buildings such as Grafton Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. The streets around a church such as St Joseph and St Padarn's Church are often among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems typically start.

Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Ask whoever fits equipment on the roof to make good the covering
- Keep clear of rooflights and fragile roof sheets
- Note where water lies after a downpour
- Book a survey every few years
For landlords and building managers, the report is a dated record of the roof’s condition. It helps when planning maintenance budgets, and it makes changes easy to spot at the next survey.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.
