FAQs for Welling
Is Welling in the area you cover?
Yes, Welling is one of the places we work. The survey and report are the same in Welling as anywhere else.
Is my home in Welling listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
How much is a survey?
Prices start from £150, including VAT. We confirm the exact price before you book, based on the roof’s size, access and package. To get a price, ring 07833 053749 or send us an email.
What if it rains on the day?
Light rain doesn’t normally stop a survey, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Tell us which days suit you as you book.
What’s the best way to book?
It is easiest to call 07833 053749 or send us an email. Tell us the address and a little about the roof, and we’ll take it from there. Surveys run on any day of the week.
Do you give a life expectancy for the roof?
We do not put a figure on it. As a guide, felt often lasts around 15 to 20 years, EPDM often 30 to 50 and GRP up to about 30, but your report describes the actual condition.
How a flat roof survey works in Welling
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. You get a photo-illustrated written report and our recommendations. We survey mastic asphalt, felt flat roofs and GRP fibreglass, and people most often book us about dips that suggest the deck is deflecting and blocked or damaged outlets.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Welling, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Where we can’t see part of the flat roof, the report says so. That way, it’s clear what was covered and what wasn’t.

Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
Flat roof surveys around Welling
About 0.4 miles south-east lies Danson House, a reminder of how long the area around Welling has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Welling is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Shop and office owners around Broadway Shopping Centre may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts. Anyone responsible for a site like Danson Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What affects the cost of flat roof surveys
Prices vary from roof to roof, for these reasons:
- How tall the building is and how easy the roof is to see
- Which survey package you book
- Whether it is a home or a commercial building
- How big the roof is
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We will give you the figure before anything is booked.
Helping us price your survey
To price your survey accurately, we will ask about:
- When you need the report by
- Your postcode, so we can check access and travel
- Anything about access we should know
- The type of building and roof, such as pitched or flat
Booking is simple: just phone 07833 053749 or drop us an email and give us some details about the property and we will explain which survey suits. The price is agreed up front.
What we are asked to look at in Welling
Flat roofs frequently get walked on for other jobs: cleaning windows, fitting aerials or air conditioning, or clearing gutters. Each visit can damage a covering not made for regular foot traffic. New brackets and fixings through the roof are another common source of leaks.
A survey makes sense if you’ve noticed:
- Pools of water lying on the roof
- Water getting in at rooflights
- Gaps at upstands and abutments
- Edge trims that have lifted or split
For a London address like Welling, it helps to know about controlled parking before the day.
What to check before booking
- Which parts of the roof they’ll actually see
- Whether they hold professional indemnity and public liability insurance
- What happens after the report arrives
- What they won’t be able to tell you

Different roofs, different checks
Felt and built-up roofs
The edges and upstands of a felt roof are typically where trouble starts. We check each one and photograph any that have split or pulled away.
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. We record any we can see, with photographs.
What happens on the day
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
Preparing for the visit
- Dig out any old roof reports or invoices
- Tell us about any leaks, stains or damp patches you know of
- Unlock side gates and any roof access doors
Arrange a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.
Related advice
What happens if roof problems are left?
A leak over an office, shop or unit can affect the people and stock underneath. A planned survey lets you budget for work rather than deal with an emergency around the business. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there’s time to plan.
To find out what your survey will cost, phone 07833 053749 or send us an email and let us know about the roof. The price is agreed before a date is set.
