Overview

EPDM Flat Roofing: What You Need to Know

What it is

EPDM is a synthetic rubber membrane used to cover flat and low-pitched roofs. Unlike traditional mineral felt, which is laid in strips and relies on lapped, torched joints, an EPDM roof is normally laid as a single sheet across the whole roof. Fewer joints means fewer places for water to find its way in. I replace old felt roofs with EPDM systems on garages, single-storey extensions, dormers, porches, bay tops and garden sheds.

Who it's for

This is for homeowners whose flat roof is leaking, ponding, blistered or simply old enough that patching it again feels like throwing good money after bad. It suits anyone who wants the problem dealt with once, rather than coming back to it every couple of winters.

When you need it

The usual signs are damp patches on a garage or extension ceiling, water dripping after heavy rain, felt that has cracked or lifted at the edges, bubbles or soft spots underfoot, moss and standing water, or edge trims that have come away. If your felt roof is 15 to 20 years old, it is often near the end of its useful life even if it isn't visibly leaking yet.

Why it pays to get it right

A flat roof lives or dies on its preparation and detailing. The deck has to be sound, the membrane must be bonded properly, and the upstands, outlets and edges need finishing correctly. Get those wrong and even a good material will fail. I explain what I find, what needs replacing underneath, and exactly what the quoted price covers before any work starts.

The cost of waiting

What Happens if It's Left

A failing flat roof rarely stays a small problem. Water that gets in through a split in the felt is absorbed by the timber deck below, and the damage spreads long before you see a stain on the ceiling.

Common mistakes

  • Painting a coating over a failing felt roof and hoping it holds.
  • Laying a new covering over a wet or rotten deck.
  • Leaving old, rotten fascia boards and edge timbers in place under new trims.
  • Choosing a quote on price alone without knowing what preparation is included.

Rotten decking

Chipboard and plywood decks swell and lose strength once wet. What could have been a straight re-cover becomes a re-deck, adding cost and time.

Damaged ceilings and contents

Leaks into extensions and garages ruin plaster, insulation, electrics and whatever you store underneath.

Cold, damp rooms

Wet insulation stops working, so extensions below a leaking flat roof become harder and more expensive to heat.

Repeat repair bills

Patching felt buys a season or two. Paying for several repairs often costs more than doing the job properly once.

My process

Five Clear Steps

  1. Step 1

    Free inspection

    I look at the roof, the deck where I can, the edges and the drainage, and talk you through what I find.

  2. Step 2

    Fixed written quote

    You get one clear price covering strip-out, any deck replacement I've identified, the EPDM system and trims.

  3. Step 3

    Strip and prepare

    The old covering comes off, the deck is checked and any damaged boards are replaced so the new roof has a sound base.

  4. Step 4

    Lay and detail

    The membrane is bonded down and the edges, upstands and outlets are finished and checked for a watertight result.

  5. Step 5

    Clear up and guarantee

    Old materials are taken away, the site is left tidy and your renewal is covered by a 20-year company guarantee.

Guarantee: EPDM flat roof renewals carry my 20-year company guarantee. This is a company guarantee, not an insurance-backed one, and it applies to renewals, not repairs.

Benefits

What You Get

Long life

EPDM is known for its long service life compared with traditional felt, which is why the renewal carries a 20-year company guarantee.

Few joints

A single sheet across most roofs means far fewer seams where leaks usually start.

Handles the weather

Rubber stays flexible in cold weather and doesn't soften and blister in summer heat the way felt can.

Low maintenance

Keep outlets and gutters clear and there's little else to do.

No surprises on price

Everything is on a fixed quote. The price you agree is the price you pay.

Clean and tidy

Customers regularly mention that I leave the job clean and take the rubbish away.

In detail

EPDM Flat Roofing Explained

How an EPDM flat roof is built

A typical EPDM installation starts with a sound deck, usually OSB or plywood boards fixed to the joists. The membrane is then bonded to the deck with adhesive, with a separate contact adhesive around the perimeter. Edge trims are fitted to the drip edges and walls, and the membrane is dressed up any abutting walls and finished under flashing where needed.

Because the rubber comes in large sheets, most domestic garages, extensions and sheds can be covered in one piece. Where joints are needed, they are made with dedicated seam tape rather than heat.

EPDM compared with felt

Traditional felt roofs are built up in layers of bitumen-based sheets, torched or bonded together. They can perform well, but joints and the constant expansion and contraction of bitumen in sun and frost are where they tend to fail. EPDM is a single, flexible membrane with no need for open flames on site, which also makes it a sensible choice next to timber, uPVC and neighbouring properties.

Where I fit EPDM

Garage roofs, single-storey rear and side extensions, flat-roofed dormers, porches and canopies, bay window tops, and garden sheds and outbuildings. I often replace fascias and trims at the same time so the whole roof edge is renewed together: one customer in RG29 had uPVC fascias and an EPDM garage roof done in the same job.

Drainage and falls

A flat roof isn't actually flat. It needs a slight fall so water runs off to the gutter or outlet rather than sitting on the surface. Where an old roof has sagged or ponds badly, I'll explain whether the fall can be corrected as part of the job, so the new roof isn't sitting under standing water from day one.

Residential focus

My work is residential: homes, garages, extensions and outbuildings across Aldershot and the surrounding area. Every job is quoted individually after a free inspection, because the size, access and condition of the deck vary from roof to roof.

Why homeowners choose Justin

I'm Justin Wigmore and I run J Wigmore Roofing Ltd on my own. There's no sales visit followed by a different crew: the person who inspects your roof is the person who quotes it, carries out the work and clears up afterwards. I've been listed on Checkatrade for 16 years with a 10/10 rating from 408 reviews, and the same themes come up again and again: excellent communication, daily updates, turning up when I say I will, a clean and tidy site every day, and a final price that matches the quote.

Every job is priced as a fixed quote after a free inspection. I hold £1 million public liability insurance, and payment is by BACS (preferred), cash or cheque.

EPDM Flat Roofing across Aldershot and nearby towns

I'm based in Aldershot and regularly work across Farnborough, Ash and Ash Vale, Farnham and its surrounding villages, Fleet, Blackwater and Hawley, Godalming, Guildford and Odiham. Housing across North East Hampshire and West Surrey ranges from Victorian terraces and inter-war semis to post-war estates and modern homes with garages and extensions, so every roof is assessed on its own merits rather than priced from a list.

Before you get in touch

It helps to know roughly where the problem is, how long you've noticed it and whether water is getting inside. Photos taken from the ground are useful but not essential. Use the form below or call me, and I'll arrange a free inspection at a time that suits you. There's no obligation, and you'll get a fixed written quote so you can decide in your own time.

FAQ

EPDM Flat Roofing Questions

How much does an EPDM flat roof cost?

Every roof is different, so I don't publish prices. After a free inspection you get a fixed written quote, and that's what you pay.

How long does an EPDM flat roof take to fit?

Many garage and shed roofs are completed in a day or two. Larger extensions take longer. I'll give you the expected timescale with your quote and agree dates with you.

What guarantee do I get?

EPDM flat roof renewals carry a 20-year company guarantee. It is not insurance-backed, and repairs are not guaranteed.

Can you fit EPDM over my existing felt?

I prefer to strip the old covering so I can check the deck underneath. Covering over a wet or rotten deck is one of the most common reasons new flat roofs fail.

Will I need a new deck?

Not always. I check it at inspection and again once the old roof is off. If boards need replacing, I tell you what and why.

Do you do flat roofs in Farnborough and Farnham?

Yes. I regularly work in Farnborough, Farnham, Fleet, Ash and across the Aldershot area.

Can you come out for a leaking flat roof?

I don't run a 24-hour or out-of-hours call-out service. If you have a leak or storm damage, get in touch during normal working hours and I'll arrange to come and look as soon as I can.

How do I pay?

Payment is by BACS bank transfer (preferred), cash or cheque. I don't take card payments.
