Flat Roofs - What They Are and Why They Leak

A flat roof is a low-pitched or horizontal roof surface finished with a waterproof membrane - typically EPDM rubber or a torch-on felt system on modern domestic properties, or old-fashioned mineral felt on older homes and extensions. The roof sits over a timber or concrete deck and drains through one or more outlets at the edge or surface.

When a flat roof leaks, the cause is almost always at a detail rather than the main field of the membrane: a failed upstand where the membrane meets a wall, a cracked or lifting flashing, a blocked outlet causing water to back up, or a split at a seam or penetration. Occasionally the main membrane fails due to age, impact damage or a defect, but the edge details are the most vulnerable points on any flat roof.

Brandon Roofers installs and repairs flat roofs in Mundford and the wider area, including Brandon, using EPDM rubber and quality felt systems. Both of these materials are a substantial improvement on the thin mineral felt used on many homes built before the 1990s, which has a typical lifespan of ten to fifteen years before it begins to fail in earnest.

First: Protect the Inside of Your Home

When an active leak is coming through a ceiling, the immediate priority is protecting what is below. Move furniture, electrical equipment and anything else of value away from the drip area. If water is collecting above a plasterboard ceiling, it will bow and eventually fail - if you can see a pronounced belly in the ceiling, keep everyone out of the room and do not poke, prod or pierce it, as it can come down unexpectedly.

Turn off any electrical circuits that serve the room if water is close to fittings or sockets. Water and live circuits are a genuine hazard, and this is the one action where speed genuinely matters.

Document the Problem

Before anything is touched or moved, take photographs of the leak point, the damp patch, any visible damage, and - if you can see it safely from a window or dormer - the roof surface itself. These photographs are useful when describing the problem to a roofer, and they are also relevant if you need to make a claim on your home insurance. Note the time and date the leak first appeared and whether it started during or after rainfall.

What You Should Not Do Yourself

The instinct to fix the problem yourself, or at least to stop the leak temporarily, is understandable. In most cases, however, amateur intervention on a flat roof causes more damage than it prevents. Here is what to avoid:

• Do not get on the roof in wet or icy conditions. A wet flat roof membrane - felt or rubber - is slippery. Falls from flat roofs cause serious injuries every year, and the combination of urgency and poor conditions is exactly when accidents happen.
• Do not apply roofing sealant, mastic or DIY roof paint over an active leak. These products require a dry, clean surface to bond correctly. Applied over a wet or contaminated membrane, they peel away within one season. They also make a professional repair harder because the contaminated area has to be cut back and cleaned before proper materials can be used.
• Do not strip or lift sections of the membrane. If you pull back a section of felt to try to find the source, you may expose the deck to further water ingress and cause additional damage before a roofer can attend.
• Do not pressure-wash the roof surface. High-pressure water forces itself into every small crack, seam and joint, and can cause far more ingress than the original problem.
• Do not overlay old felt with a new layer yourself. It looks straightforward but the deck condition beneath, the falls, the upstand detailing and the flashing integration all need to be assessed and done correctly. An overlaid roof without addressing those factors will fail again.

Temporary Measures That Are Reasonable

There are a small number of things that can limit damage while you wait without making the roofer's job harder:

• If there is a safe and dry way to reach the outlet from ground level and it is visibly blocked with leaves or debris, clearing it will at least stop water backing up further. Only do this if you can reach it without climbing onto the roof surface itself.
• A heavy-duty polyethylene tarpaulin weighted or fixed at the edges can provide short-term protection over a damaged area if the roof can be accessed safely in dry conditions. This is a temporary measure only - it is not waterproofing and will not survive prolonged wind. It also needs to be secured so it does not become a wind hazard.
• Placing absorbent material (old towels, buckets) below the internal drip point and checking them regularly prevents further damage to floors and belongings in the short term.

When It Is an Emergency

A small, steady drip during rain is an urgent problem but not an emergency in most cases. A sudden large water ingress - particularly into a room with electrical fittings - is a different matter. If water is coming through a ceiling near a light fitting or around a consumer unit, switch off the relevant circuit at the fuse board and do not use the room until the electrical system has been checked. Call a roofer and explain the scale of the problem when you phone.

If you are in any doubt about safety, particularly involving electrics, the priority is to get people out of the affected area first.

What to Tell the Roofer When You Call

A clear description of the problem helps a roofer prepare properly and give you a more useful response over the phone. Useful things to mention:

• Where the roof is (garage, extension, bay top, main building)
• The approximate size of the roof if you know it
• The material on the surface if you can see it - rubber, felt, painted surface
• When the roof was last worked on and by whom, if you know
• Where the internal drip or damp patch is appearing in relation to the roof above
• Whether the problem started during heavy rain or appeared gradually

This information helps narrow down likely causes before the roofer is even on site, and means the survey takes less time.

What Happens During a Flat Roof Inspection

A proper flat roof inspection involves walking the entire surface, checking the main membrane for cracks, blisters and splits, checking every upstand and flashing at wall junctions, inspecting the outlet for blockage and correct positioning, and pressing on the deck in areas of concern to check for softness. A roofer who inspects a flat roof from the ladder or from the eaves edge only is not doing a thorough job.

The inspection should give you a clear account of what has caused the leak, what other areas are at risk, and whether the roof is worth repairing or approaching replacement age. You should receive a specific description of the work proposed and a clear price before anything is agreed.

Flat Roof Costs - Typical Figures

Full replacement on a garage or extension roof of 15 to 25 square metres costs in the region of £1,200 to £2,500 for a quality EPDM or felt system. These are typical current UK figures and will vary with deck condition, access and the complexity of the detailing on your specific roof.
