Common questions in Nash Mills
Will you come out to Nash Mills?
Yes, we do. We work right across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
My home in Nash Mills has a flat-roofed garage or porch. Is it worth having that looked at?
Often, yes, so mention it as you book. Many homes in new towns like Hemel Hempstead have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
Do you check flat roofs for asbestos?
Our survey doesn’t include asbestos testing. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
How do I arrange a flat roof survey in Nash Mills?
Simply phone 07833 053749 or drop us an email. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
Does a flat roof survey replace a RICS survey?
No. We look closely at the flat roof rather than the whole building. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
Do you need to get into the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
How soon will I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when booking.
How a flat roof survey works in Nash Mills
Ponding is frequently the first sign that something on a flat roof isn’t right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey GRP fibreglass, EPDM rubber and mastic asphalt, and the problems we’re asked to look at most are gaps at upstands and abutments and a sagging deck under the covering.
Outbuildings, garden rooms and garages in places like Nash Mills frequently have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It is worth mentioning them when you book, so the visit can include them. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Rented homes, blocks and businesses
Letting agents and landlords in Nash Mills book surveys as well as householders. A photo-illustrated written report gives you a clear record of the flat roof, which helps you plan work between tenancies.

The survey, step by step
It’s useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take about 1–2 hours for a house, and about three to four hours for a commercial roof. A visit to Nash Mills is planned like any other: the time, the access and where to park are agreed beforehand. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before the survey
- Point out any leaks or damp patches
- Make sure the loft hatch can be reached
- Agree roof access with the managing agent if it’s shared
Getting a price
If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or send us an email whenever suits you.

Flat roof surveys around Nash Mills
The wider area around Nash Mills has a long history of building, with High Elms Manor about 3.1 miles south-east. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. Nash Mills is part of Hemel Hempstead, one of the post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all.
For an older house near a landmark such as Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Apsley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Tips from our surveys

- Keep records of when the roof was laid and what work has been done
- Keep clear of rooflights and fragile roof sheets
- Limit foot traffic on the covering

Clear leaves and silt from outlets and gutters, above all in autumn. Water that can drain away does far less harm than water that sits.

Common roof problems in Nash Mills
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, and in time it can open up splits and cracks. Older coverings that have lost their flexibility are the most likely to suffer.
Most people get in touch after spotting something like this:
- Pools of water lying on the roof
- Blocked or damaged outlets
- Leaks around rooflights
- Damaged trims at the roof edge
Anyone responsible for a site like Nash Mills Church of England Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
