Flat roof survey in Holywell, Greater London
Get a clear view of the flat roof at a property in Holywell. We visit on weekdays and at weekends.
- Blisters and bubbles in the covering
- Outlets that hold water back
- Splits, cracks and crazing
What we do, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit typically takes between one and two hours for a house, with bigger or more complicated roofs taking longer. Surveys in Holywell can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Getting ready for the survey
- Point out any leaks or damp patches
- Leave side gates unlocked
- Have any paperwork from past roof work to hand
How to book
Booking is simple: just ring 07833 053749 or send us an email and give us some details about the property and we’ll explain which survey suits. The price is agreed up front.

About our flat roof survey in Holywell
Each type of flat roof has its own weak points. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it’s doing helps you plan what comes next. If you’ve noticed splits, cracks and crazing and blisters and bubbles in the covering, a survey will tell you what’s going on.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Holywell shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

How the survey changes by roof type
Mastic asphalt
Mastic asphalt is a heavy, seamless covering often found on older blocks, balconies and commercial roofs. We look for crazing, cracks, blisters and splits at the skirtings.
Felt and built-up roofs
The edges and upstands of a felt roof are normally where trouble starts. Every upstand and edge is checked, with photos of any that have lifted or cracked.

Can I check my roof myself?
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
When to book a survey in Holywell
No flat roof covering lasts for ever. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, though workmanship and upkeep make a big difference. A survey shows how yours is holding up, whatever its age.
We are often asked to look at:
- Standing water left after rain
- Signs of deflection in the roof deck
- Outlets that hold water back
- Edge trims that have lifted or split
Shop and office owners around Charter Place may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.
What to check before booking
- Is VAT included in the price?
- What they won’t be able to tell you
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Are they insured for the work?

What a flat roof survey looks like in Holywell
With High Elms Manor about 4.1 miles north, Holywell sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof. 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. If your home in Holywell is one of them, bay roofs, hips and later dormers each have their own details. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If your home is one of the older ones in the streets near St Oswald's Parish Church, the flat roofs on later extensions tend to wear out long before the main roof. If you look after a building such as Westfield Academy, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Holywell is about 2 miles south-west of Watford, in Greater London. Houses, flats, blocks and commercial buildings in Holywell can all book flat roof surveys, with a written report and photographs every time. Our Greater London coverage includes Holywell. You can also see our page for London.

Why get it checked now?
Ponding seldom gets better on its own. Most frequently it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. In Holywell, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
Prices start from £150, with VAT included, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the exact price before you book.
