Flat roofs cover everything from garage tops and kitchen extensions to large bay window canopies and full commercial buildings. They work well when they're installed correctly, but a poorly laid flat roof will blister, pond water and fail within a few years. If your flat roof is leaking, showing bubbles in the surface, or simply coming to the end of its life, it's worth getting it looked at before water finds its way into the structure below.
Not all flat roofing materials are the same, and the right choice depends on the size of the roof, the budget and how the building is used. We work with two main systems:
We'll talk you through both options and explain which suits your roof before any work starts. There's no point fitting a top-end system to a small outhouse roof if a well-installed felt system will do the job just as effectively.
A flat roof replacement starts with stripping back the old covering to expose the deck beneath. The deck is usually timber boards or plywood, and this is the point where hidden rot or damage becomes visible. Any soft or damaged decking needs to come out and be replaced before the new waterproofing goes on - putting a new roof over a compromised deck is one of the most common reasons flat roofs fail prematurely.
Once the deck is sound, we check the falls. A flat roof isn't truly flat - it needs a slight slope to carry rainwater towards the outlet or guttering. Without adequate fall, water sits on the surface, accelerating wear and eventually finding its way in through even small imperfections. Getting the fall right at installation stage is a detail that separates a roof that lasts from one that causes problems in two or three years.
The new membrane is then fitted, with careful attention to all upstands, abutments and edges. These junctions - where the roof meets a wall, a parapet or a skylight frame - are the most vulnerable points on any flat roof. Each one needs to be properly dressed and sealed.
Cold-applied felt, in particular, tends to crack and split as it ages and becomes brittle. Blistering is another common problem - this happens when moisture gets trapped beneath the surface during installation and expands with heat. A blister that bursts leaves an open wound in the waterproofing.
Ponding water is a warning sign that the falls are insufficient or that the outlet is blocked. Left untreated, standing water adds dead weight to the roof structure and accelerates deterioration.
Not every flat roof needs to come off completely. If the deck is sound and the membrane has isolated areas of damage, a targeted repair can extend the roof's life at a fraction of the cost of replacement. We'll tell you honestly whether repair is a sensible option or whether you're better off replacing - patching a roof that's reached the end of its life only delays the inevitable and often ends up costing more in the long run.
As a rough guide, flat roof replacement in Norwich typically costs in the region of £70 to £120 per square metre depending on the system chosen and the condition of the existing deck. That figure rises if significant decking replacement is needed.
