Flat roof surveys and leak tracing in Ely

When a leak in Ely keeps coming back after repairs, a flat roof survey is the sensible next step. We trace the water from the stain back to its entry point, check moisture levels across the roof, and confirm doubtful areas with a small core sample before recommending anything.

When is a flat roof survey worth it in Ely?

Businesses in Ely with a flat-roofed building can't plan maintenance around guesswork. A survey sets out what needs doing now, what can wait and roughly what each item will cost, so the work can be scheduled with as little disruption as possible.

Ely's flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches, with plenty on terraced streets with flat-roofed rear kitchens and bathrooms too. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

How much does a flat roof survey cost in Ely?

How do you find where a flat roof is leaking?

By working from the evidence inside back to the likely entry points outside, then confirming the path with moisture readings and, where needed, small test openings.

We start indoors, looking at where the staining is, when it appears and whether it follows rain, wind from one direction or cold weather. Then, on the roof, we check the details where most leaks start: upstands and flashings, laps and seams, outlets, gutters, edge trims, rooflight kerbs and anything that passes through the covering. Walls, copings and cavity trays above the roof are checked too, because water getting in behind an upstand can look like a roof leak.

A moisture meter shows where the covering, or the material beneath it, is holding water, and readings across the roof help map how far the wet has spread. Meter readings are a guide, not proof, so where they suggest a problem we may take a core sample: a small cut through the covering and insulation to see what is underneath and whether the deck is sound. The opening is sealed again with compatible material before we leave.

Condensation can also look like a leak, especially in older cold roofs without adequate ventilation, and the survey considers that possibility too. The flat roof leaks guide explains the common causes.

What's included?

  • Moisture meter readings across the roof
  • Inspection of the covering, upstands, edges and outlets
  • Core samples where readings need confirming
  • Plain written report with ranked recommendations

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
