Flat roof surveys and leak tracing in Ashford, Surrey

When is a flat roof survey worth it in Ashford, Surrey?

In Ashford, Surrey, as elsewhere, people often book a survey after a repair that didn't hold. When a leak returns, it usually means the first fix treated the symptom rather than the cause. Tracing the actual entry point saves paying for the same repair twice.

In a town like Ashford, Surrey, flat roofs are commonly found on newer estates where the first extension roofs are now being replaced or lock-up garage blocks on estates. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.

How long does a flat roof survey take and how long is it valid?

A survey of a typical garage or extension roof usually takes an hour or two on site. Larger, higher or multi-area roofs take longer, and the written report follows afterwards.

A survey describes the roof on the day it was inspected. It stays a useful baseline for planning, but roofs change, particularly older ones and after a hard winter or a storm. If you are using a report to plan a replacement some time later, or after a fresh leak, a short follow-up check is sensible. For roofs you manage over the long term, a regular inspection backed by the maintenance checklist picks up problems early.

What's included?

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

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.
