When to book a survey in Colney Butts
Flat roofs take the full force of the weather on a surface that drains slowly. In time, the covering dries out, cracks and loosens at its edges and laps. People normally call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
A survey can pick up problems such as:
- Cracked or split membrane
- Upstands pulling away from walls
- Outlets choked with leaves and silt
- Leaks around rooflights
High Elms Manor lies about 3.6 miles north, so building around Colney Butts goes back a long way. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once.
Before booking any roof surveyor
- How long they’ve been surveying roofs
- What exactly goes into their report
- Whether the inside of the roof is included
- How they plan to inspect the roof safely
Flat roof surveys for homes and businesses in Colney Butts
Water through a flat roof doesn’t always come in where the stain is. It can run along the deck from a split, an open lap or a failed upstand some distance away. Our survey covers the whole roof, not just the part above the mark, and photograph anything that could let water in. A roofer can then start from a clear picture of the problem. Typical surveys look at blocked or damaged outlets and failed upstands where the roof meets a wall, on single-ply membranes, GRP fibreglass and EPDM rubber.
In a smaller place like Colney Butts, some flat roofs sit in the open, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for. A flat roof that still holds water days after rain is also worth a closer look.
After the visit, you get a written report with photographs, emailed to you. It sets out the condition of the flat roof, any defects and our written recommendations.

Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note where water lies after a downpour
- Limit foot traffic on the covering
- File the paperwork for the roof and any repairs
- Make sure new fixings through the roof are properly sealed
Once we’ve been, the findings are written up with photos. It covers the type of covering, its condition and each defect, with our recommendations. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.
Different roofs, different checks
Single-ply membranes
On single-ply roofs, the welds between sheets are the key detail. We check seams, corners and the joints around outlets and upstands.
Felt and built-up roofs
On felt, the upstands and edge details often fail before the main surface. We check each one and photograph any that have split or pulled away.
Checking the roof from the ground
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Why it’s worth a survey now in Colney Butts
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. We can pick up worn covering and failing details sooner, while there is still time to plan the work. With lower homes, common in places like Colney Butts, there is little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.

How it works
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. It usually takes about one to two hours for a small flat roof at home, and longer for a large commercial one. Being in a smaller place like Colney Butts doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- 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.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Before the survey
- Clear the way to the loft hatch
- Note where any stains or damp appear
- Agree roof access with the managing agent if it is shared

Advice
Common questions in Colney Butts
Can you look at the flat roof of a hotel or office near Colney Butts?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building.
How do I find out if my home in Colney Butts is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
Is it a structural engineer’s report?
No. Our survey isn’t a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
How long does the survey take?
That depends on the size and shape of the roof, but most surveys take about one to two hours for a house; commercial roofs usually need 3–4 hours. The written report follows by email.
