Flat Roof Survey in Mackerye End
We take a careful look at the flat roof at your property in Mackerye End, and put it all in a written report with photographs.
- Upstands pulling away from walls
- Signs of deflection in the roof deck
- Standing water left after rain
Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- File the paperwork for the roof and any repairs
- Clear roof outlets and gutters each autumn
- Check from a window for ponding after heavy rain
- Ask whoever fits equipment on the roof to make good the covering
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. It is written in plain English, with a photo of each defect, so anyone reading it can see what we saw.
Keep outlets, gutters and hoppers clear, particularly after the leaves fall. A flat roof that drains well wears much more slowly.
Flat roof surveys for homes and businesses in Mackerye End
Many commercial buildings and blocks of flats have big flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. We record the condition with photographs so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so it helps if you call 07833 053749 or email us with the address and a rough idea of the roof area. We survey GRP fibreglass, felt flat roofs and upstands and outlets, and people most often book us about splits and cracks in the covering and blistering in felt or asphalt.
Flat roofs on exposed homes in small places like Mackerye End take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Mackerye End: your questions answered
How do I find out if my home in Mackerye End is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Will you come out to Mackerye End?
Yes, Mackerye End is on our map. Villages and rural addresses get the same survey as a town house.
Do you cover flat roofs on blocks of flats?
Yes. Commercial and residential flat roofs are both covered. A commercial roof typically takes about 3 to 4 hours on site, longer if it is large or complex, with larger roofs quoted on their size.
Will you check the loft?
Where it’s relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
What’s the best way to book?
Simply ring 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
What does ponding on a flat roof mean?
Standing water on a flat roof deserves a closer look. It often means a blocked outlet, poor falls or a dipping deck, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
Which flat roof coverings do you cover?
Felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply membranes are all part of the work. The report names the covering and explains its condition.

How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. It usually takes an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Somewhere like Mackerye End needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- 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.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
Before we arrive
- Find any records of previous roof work
- Show us where any leaks or stains appear
- Keep pets in another room
How to book
Every survey is priced before it is booked, so you know where you stand. Our price is from £150, including VAT. To book, ring 07833 053749 or email us.

Common roof problems in Mackerye End
Buyers often book after their home survey suggests a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. Either way, you get a clear record of the roof, with photographs.
People normally book a survey after spotting one of these:
- Failed seals around rooflight kerbs
- Standing water left after rain
- Damaged trims at the roof edge
- Blistering in felt or asphalt
If you live in an older home near All Saints, the joins between later flat roofs and the old walls are where problems usually start.

Checking the roof from ground level
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Flat and commercial roofs around Mackerye End
With Shaw's Corner about 2.3 miles east, Mackerye End sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Anyone responsible for a site like Sauncey Wood Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Harpenden station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

When you need someone else

- An exact number of years the roof has left
- Parts of the roof that aren’t safe to walk on or view
- Whether the deck or joists are strong enough
If in doubt, ring 07833 053749 or drop us an email and we will point you to the right survey before you book. What our survey covers.

What happens if roof problems are left?
If you are buying, find out about the flat roof before you exchange. Once you’ve exchanged, any work on the roof is down to you. A report gives you facts to put to the seller or agent. For an older or listed building in a place like Mackerye End, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
