Flat roof survey in Marshalswick: what you get

Our Basic Survey, from £150, gives you a visual inspection with photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Larger commercial roofs are quoted for their size. If you’ve noticed cracked or split membrane and blocked or damaged outlets, we can find out what’s behind it, whatever the roof.

Flat roofs in smaller places like Marshalswick can be more exposed, especially where nothing shelters them, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. Standing water that lingers for days after rain is another sign worth watching for.

Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What a survey costs

Survey packages start from £150, with VAT included. The price for your roof depends on:

  • Which survey package you book
  • Height and safe access
  • Features like valleys, chimneys, dormers and parapets
  • Extensions, dormers and garages with roofs of their own

Flat roof survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

What we need to know

You don’t need to know any roofing terms. It is enough to let us know:

  • Any stains, drips or damp patches you’ve seen indoors
  • The address and postcode of the property
  • Any deadline, like an exchange date
  • Pictures of the roof from a safe spot, if you have them

If you’re buying, it is useful to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you’re ready.

Roof by roof

GRP fibreglass

A GRP fibreglass roof is a hard, resin-bonded surface over a timber deck. We look for cracks at board joints, around trims and at upstands.

Rooflights and upstands

Upstands at walls and parapets need to stay watertight as the building moves. We check for splits, gaps and loose flashings above the upstand.

How it works

We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. A typical visit takes between one and two hours at most homes, though large, tall or awkward roofs take more time. With a bit of garden around a house, as there often is around Marshalswick, the roof can be viewed from several angles. Mention any side of the property we can’t get to. Inside, the loft is checked where it can be reached safely.

  1. You let us know about the roof, its covering if you know it, and any leaks.
  2. The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
  3. The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
  4. Where there is safe access, we look at the ceilings and spaces below for signs of water.
  5. You get a written report with photographs and our recommendations.

Preparing for the visit

  • Point out any leaks or damp patches
  • If it isn’t your property yet, arrange access through the agent
  • Make sure pets are kept safely away

Book a survey

A quick phone call is typically the easiest start: phone 07833 053749 or send us an email, and we will ask about the building and what you need. The price is agreed before a date is set.

What happens if roof problems are left?

A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes some details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. On a bungalow or cottage around Marshalswick, the roof sits close to the rooms below, so water can show inside quickly once it gets past the covering. Catching the cause first saves redecorating as well.

A Basic Survey starts from £150, including VAT. Standard is from £250 and Premium from £400, both with VAT included. We confirm the price for your roof before you book.

Can I check my roof myself?

During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.

After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.

What we can’t see

No survey can tell you everything, and it is better to know them up front. Keep these in mind:

  • The condition of the deck or insulation hidden under the covering
  • Parts of the roof that are not safe to walk on or view
  • Testing older roof sheets for asbestos

If you are not sure which survey you need, call 07833 053749 or use the contact form and we will give you a straight answer. What a survey covers and does not.

Roof types and parts we check

  • GRP fibreglass

FAQs for Marshalswick

Do you carry out roof surveys in Marshalswick?

We do. The survey and report are the same in Marshalswick as anywhere else, and visits run on weekdays and weekends.

Will you come out to Marshalswick?

We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.

Do you carry out surveys on Saturdays and Sundays?

We survey seven days a week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when you book.

I live in a flat. Can you survey the roof?

Yes. A shared roof needs access agreed first, with the building owner or managing agent. Tell us about it as you book and we will explain what’s needed.

Can you tell me how long my flat roof will last?

A precise figure is not something we give, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.

Can you find where water is getting through my flat roof?

We check the covering and every detail where leaks commonly start, and photograph anything that could be letting water in. If the source is hidden, we may suggest a leak investigation or electronic leak detection.

Do you survey commercial flat roofs?

Yes. We survey flat roofs on offices, shops, industrial units and blocks of flats. Larger commercial roofs are quoted for their size and access, so please call 07833 053749 or send us an email with the details.

Local flat roofs in Marshalswick

Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Batchwood Hall, about 2 miles west, is one of the historic houses in the wider area around Marshalswick. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.

If your home is one of the older ones in the streets near Saint Mary's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you own a rental within reach of St Albans station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Shop and office owners around The Maltings may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.
