Independent roof leak investigations in St Margarets

What we can’t see

  • Whether rotten timbers meet design loads
  • The repair itself (the investigation finds and reports the cause)
  • An intermittent leak that shows no trace on the day

If in doubt, call 07833 053749 or drop us an email and we will suggest the right survey. The full list of what we check.

Roof leak investigation in St Margarets: what you get

Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We look at the roof surface and the ceiling below. Leaks under flat extension, garage and dormer roofs are common. An ageing felt roof is a frequent culprit. If you’ve noticed water through the ceiling under a flat roof and staining around the chimney inside, a survey will tell you what’s going on, on the roof space, chimney stacks and slate and tile slopes alike.

Roofs in small places like St Margarets often stand in the open, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.

The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

St Margarets questions

Do you cover smaller places like St Margarets?

Yes, St Margarets is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.

Is St Margarets in the area you cover?

Yes, St Margarets is one of the places we work. Every survey there gets the same written report with photographs.

Do I have to be there for the survey?

It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.

Will you check the loft?

Usually, if there is one and it can be reached safely. The loft space can show things the outside cannot, such as damp timbers, staining or daylight.

Is it the same as a RICS Level 2 or Level 3 survey?

No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.

How experienced are you?

Over 20 years and more than 5,000 surveys, across London and South East England.

Will you definitely find the leak?

Not every leak can be pinned down in a single visit. Many leave clear signs, but intermittent leaks that need particular weather can be harder. We report what we found and the likeliest sources.

Landlord and commercial surveys in St Margarets

Landlords and agents in St Margarets book surveys as well as householders. The report gives you a dated record of the leaking roof, with photographs, which helps you plan work between tenancies.

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.

When to book a survey in St Margarets

Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. On slate roofs, slipping is frequently caused by corroded nails.

A survey makes sense if you’ve noticed:

  • Water marks that spread in wet weather
  • Damp patches next to the stack
  • Water through the ceiling under a flat roof
  • Damp underlay across a wide area

For site and facilities teams at buildings such as The Cranbourne Primary School, tracing a leak on a big roof starts with where the water appears and works back.

Questions to ask before booking

  • Whether the inside of the roof is included
  • Are they insured for the work?
  • Whether any drone flown is registered with the CAA
  • Whether you can ask questions once you have the report

What a roof survey includes

What we do, step by step

A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from each safe vantage point, take photos as we go and make notes for the report. It typically takes about one to two hours, more where the leak is intermittent or the roof is large. Somewhere as small as St Margarets, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.

  1. We start with what you’ve seen: where the stain is and when it gets worse.
  2. We check the stain, the ceiling and the loft above it.
  3. Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
  4. We use moisture detection, and thermal imaging where it is useful.
  5. We email a report with photos, the likely entry point and recommendations.

Before we arrive

  • Leave side gates unlocked
  • Gather any invoices or paperwork from past roof work
  • If the roof is shared, arrange access with whoever manages the building

Advice

Checking the roof from ground level

After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.

During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.

Roof leak investigations in St Margarets: local notes

In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. The covering and its details give the first clues when tracing where water is coming from. An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent.

Landlords with a home close to St Margarets (Herts) station may find that tracing a leak quickly matters when a tenant is living with it. Take an older house close to Parish Church of St Andrew: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
