What Flat Roofing Actually Involves

A flat roof is not truly flat - it must have a slight fall, typically around 1:40, so that rainwater drains away rather than sitting on the surface. When that fall is wrong, or when the membrane, felt, or flashing is installed badly, water finds a way in. The leaks that give flat roofs a bad reputation are almost always the result of poor installation rather than a problem with the roofing system itself.

The two main systems used on domestic properties are EPDM rubber and built-up felt. EPDM is a single-ply rubber membrane bonded or ballasted to the deck. It is flexible, handles temperature changes well, and has a proven track record on extensions and garages. Traditional mineral felt is cheaper upfront but the quality varies enormously depending on the number of layers and how carefully the laps and edges are finished. A properly installed three-layer felt roof can still perform well; a rushed single-layer job will not last.

On any flat roof the critical details are the upstands (where the roof meets the wall), the drip edges, the outlet positions, and any penetrations for pipes or rooflights. These are the areas where leaks begin. A contractor who gives these junctions proper attention is worth far more than one who covers the main field quickly and moves on.

How to Choose a Flat Roofing Contractor in Felmingham

There is no shortage of roofers operating in and around Felmingham and the wider North Walsham area, which makes it harder, not easier, to pick a good one. The questions below will help you separate contractors who do solid work from those who will cost you more in the long run.

Questions to Ask Before You Agree to Anything

• What system are you recommending, and why? A contractor should be able to explain why EPDM, felt, or another system suits your specific roof - the size, the deck condition, the fall, and how the roof is used. Vague answers are a warning sign.
• What is the deck condition, and will you check it before pricing? The roofing membrane sits on a deck - usually timber boarding or plywood. If the deck is rotten or soft, it must be replaced before the new covering goes on. A contractor who prices without looking at the deck may come back mid-job asking for more money, or worse, may lay a new membrane over a failing deck and leave you with the same problem in two years.
• What fall does the roof currently have, and is it adequate? If the fall is insufficient, adding a new layer of the same material will not solve ponding. Some contractors can build up a tapered insulation board to correct the fall at the same time as re-roofing. Ask whether this is needed and what it would cost.
• How will you handle the upstands and flashings? Ask specifically about lead or aluminium flashings where the roof meets brickwork or render. These details should be described in any written quote, not left as assumptions.
• What is included in the price? Stripping the old covering, disposing of waste, replacing any rotten decking, and making good the edges should all be itemised. A quote that simply says "supply and fix new flat roof" tells you very little.
• Can you provide references from similar jobs? A roof on a single-storey extension is different from a large garage roof. Ask whether they have done similar work nearby and whether you can speak to the customer or see the finished job.
• Do you carry out the work yourselves, or do you subcontract? Some companies quote the job and then pass it to someone else. If the original contractor is not on site, it is harder to hold anyone accountable if something goes wrong.

Red Flags to Watch For

A contractor who asks for a large cash deposit before any work starts is worth treating with caution. A reasonable deposit to cover materials is understandable; paying for the whole job upfront is not. Equally, be wary of anyone who cannot give you a written, itemised quote. If the scope of work is not written down, disputes become impossible to resolve.

Pressure selling - being told you must book today or the price goes up - is another warning sign. A reputable contractor will give you time to compare quotes. A flat roof on a typical domestic extension is not an emergency purchase, and you should take the time to get two or three written quotes before deciding.

Very low prices should prompt questions rather than immediate acceptance. Undercutting is often achieved by using fewer layers of felt, skipping the primer coat on an EPDM bond, or cutting corners on the deck inspection. The roof may look fine for a year and then fail in exactly the ways a proper installation would have prevented.

What a Good Written Quote Should Include

Before you sign anything, make sure the quote sets out the following in writing:

• The roofing system to be used (product type and specification)
• Whether existing covering and deck boards will be stripped
• How any rotten or soft decking will be dealt with, and at what cost
• The method for upstands, trims, and flashings
• How the waste will be removed
• The payment schedule
• The expected duration of the work

If a contractor will not put these details in writing, that itself tells you something useful.

Understanding Material Lifespans

EPDM rubber membranes, when properly installed, have manufacturer-rated lifespans of 20 to 50 years depending on the product and thickness. Three-layer mineral felt, done properly, can last 15 to 25 years. These are material characteristics, not guarantees of any specific job - the quality of the installation matters as much as the material chosen. Asking a contractor what the expected lifespan of their recommended system is, and why, is a reasonable question and any experienced roofer should answer it without hesitation.

Flat roof costs in North Norfolk vary depending on system, deck condition, and roof size. EPDM on a typical domestic extension or single garage typically costs in the range of £70 to £120 per square metre fully installed, including stripping the old covering. Built-up felt is generally cheaper upfront. These figures are a guide - get itemised quotes for your specific roof.
