Flat Roofs and Why They Need Prompt Attention

A leaking flat roof on a garage, extension or dormer will not heal itself. Water entering through a split membrane or failed flashing finds timber decking, joists and ceiling materials quickly. The longer it is left, the more extensive the damage - and the more expensive the eventual repair. Knowing what to do in the hours or days before a roofer can attend can genuinely limit the harm.

This page covers the practical steps worth taking while you wait, what you should not attempt yourself, and what to expect when a roofer does arrive. We also cover the service itself: what flat roofing involves, the materials used, typical costs and what good work looks like.

What Flat Roofing Covers

Flat roofs are used on garages, single-storey extensions and dormer sections of loft conversions. They are not truly flat - they are laid to a shallow fall, typically between 1 and 5 degrees, so water drains to a gutter or outlet. The surface is either a bitumen felt system (the standard covering on most properties built or extended before around 2010) or a modern single-ply rubber membrane such as EPDM. The structural deck underneath is typically timber boarding, OSB or plywood.

Common failure points include splits or blisters in the felt surface, failed or lifted lead flashing at a wall junction, open perimeter trim at the edges, and blocked outlets causing water to pond and find its way through the membrane under pressure.

What to Do While You Wait for a Roofer

If your flat roof is leaking actively, the priority is protecting the inside of the building. These are the steps that make a real difference:

• Protect the room below. Move furniture, electronics and anything of value away from the affected area. Place buckets, bowls or trays to catch dripping water. Lay down old towels or plastic sheeting on the floor to absorb or channel water that spreads.
• Locate the water entry point if you can - from the inside. Water does not always drip directly below where it enters the roof. It may travel along a joist or rafter before appearing at the ceiling. Note where the ceiling is wet or stained, and compare it with the roof layout above if you can. This information is genuinely useful for the roofer when they arrive.
• Check whether the outlet or gutter is blocked. If the roof has an outlet and it has become blocked, clearing it from ground level or from a safe position at the edge of the roof may relieve the immediate ponding. Use gloved hands or a tool to remove leaves and debris from the outlet opening. Do not lean over the edge of the roof to do this.
• Photograph everything. Take photos of any visible damage to the roof surface from ground level or from a window. Photograph the wet ceiling and walls inside. This helps the roofer assess what happened and provides a record if you need to discuss costs or make a claim on a home insurance policy.
• Isolate electrics in the affected area if water is near a light fitting or socket. A dripping ceiling near a light fitting is a genuine hazard. Switch off the circuit at the consumer unit rather than using the individual switch, and do not turn it back on until the ceiling has dried out and been checked.

What Not to Do Yourself

The instinct to get up there and fix it is understandable, but flat roofs present specific hazards that make unqualified access a bad idea.

• Do not walk on a flat roof that may have soft or rotten decking. A deck that has been wet for any length of time can have areas that will not support weight. You cannot tell by looking where the rotten sections are. Breaking through a compromised deck is a serious fall risk.
• Do not use sealants or mastic as a first-aid fix without understanding what you are sealing. Applying a surface sealant over a split that extends through the felt and into wet decking traps moisture inside the structure. The deck continues to rot, and the sealant gives a false sense that the problem is resolved. A targeted patch using compatible material by someone who has inspected the deck is very different from a tube of sealant applied blind.
• Do not apply any product to an EPDM rubber membrane without checking compatibility first. Some sealants and adhesives are not compatible with EPDM and will cause the membrane to swell or delaminate around the repair area, making the eventual professional repair more complex and costly.
• Do not attempt to re-dress lead flashing without training. Lead is a material that needs to be worked correctly to remain waterproof. A flashing that has been pulled further up the wall by an untrained hand, or that has been pushed back and caulked, will not seal - and disturbing the lead makes the subsequent professional repair harder.
• Do not use a pressure washer on a flat roof surface. If moss or algae is part of the problem, a pressure washer will force water under existing laps and can damage a felt surface that is already beginning to degrade.

What to Expect When the Roofer Arrives

A roofer attending a leaking flat roof should carry out a proper inspection before quoting for any work. That means getting on the roof, not just looking from the ground. They should check the surface for splits, blisters, lifted laps and open seams. They should check the flashings at every wall junction and the condition of the perimeter trim. If there is any evidence of ponding they should assess the fall and the outlet. Where the deck may be wet or compromised, a good roofer will probe or check the boarding before committing to a repair-only approach.

Following that inspection, they should tell you clearly whether the problem is localised - making a repair worthwhile - or whether the roof surface is at the end of its working life and a full replacement is the better answer. Both options have their place; the right one depends on what the inspection finds.

Typical Costs for Flat Roofing Work

A localised repair - cutting out a damaged section, checking the deck underneath and patching with a compatible material - typically costs between £150 and £450 depending on the area affected and whether any deck boarding needs replacing. Full replacement of a standard garage roof of around 15-18 square metres typically runs from £1,200 to £2,200, depending on the material chosen and deck condition. EPDM rubber membranes and torch-on felt systems sit at broadly similar price points for residential work, with variation driven more by deck condition and detailing complexity than the membrane cost itself.

Emergency and Storm Damage Situations

If high winds have lifted perimeter trim, disturbed lead flashing or caused other visible damage to a flat roof in Kedington or nearby, the priority is to limit further water ingress before full repair is carried out. A roofer attending storm damage will typically make the roof as watertight as practically possible at the first visit, with full repair or replacement following once access and conditions allow for proper work. If you have home buildings insurance, report the damage to your insurer before any repair work starts and ask them whether they need a survey completed first.
