What is Flat Rubber Roofing?

At Alvadac, we use EPDM rubber for all our flat roofing projects and for good reason. This single-ply membrane is made from ethylene and propylene (sourced from natural gas and oil), then vulcanised into durable, flexible sheets ideal for flat roofs of all shapes and sizes.

Whether it’s a garage, shed, extension, or even a treehouse, EPDM provides a seamless, waterproof layer that protects your property all year round. It comes in large sheets that are cut to size and installed in a single piece using a strong bonding adhesive, making the process quick, clean, and highly effective.

EPDM is one of the most popular and cost-effective flat roofing materials on the market. It’s built to last for decades, requires very little maintenance, and can handle extreme temperatures from freezing winters to summer heatwaves. It also helps regulate indoor temperatures, meaning better energy efficiency and lower bills. 

Benefits of EPDM Flat Rubber Roofing

At Alvadac, we’re passionate about the many benefits flat rubber roofing can offer. Here are just a few reasons why so many property owners choose EPDM:

Long-Lasting & Boosts Property Value

EPDM is incredibly durable and water-resistant, making it ideal for the unpredictable British climate. A properly installed rubber roof can last 30 to 50 years with minimal upkeep. That kind of longevity can add real value to your property, especially if you’re planning to sell in the future.

Simple Repairs (If You Ever Need Them)

EPDM rarely needs fixing, but if it does, repairs are quick and stress-free. Because it’s a single sheet of rubber, any damage can be easily patched without disturbing the structure underneath, saving you time and money.

Custom-Fit for Every Roof

No two roofs are the same, which is why every Alvadac project starts with a detailed inspection and measurement. We tailor each installation to your exact roof shape and size, ensuring a perfect fit and seamless waterproofing.

No Cracking, Blistering or Rot

Rubber is naturally flexible and resistant to the most common roofing issues, like cracks, blisters and rot. That means your roof stays in great shape, even as the seasons (and temperatures) change.

Low Maintenance

Compared to other materials, EPDM flat roofs require very little maintenance. Occasional inspections and light cleaning are usually all that’s needed. Many of our customers go decades without lifting a finger and repainting every 10 years is optional, not essential.

Environmentally Friendly

EPDM is one of the most eco-conscious roofing materials available. It uses less energy to manufacture, can be made from recycled materials, and is fully recyclable at the end of its life making it a great choice for greener living.

Helps Cut Energy Bills

Rubber roofing helps regulate temperature in your home. In summer, it reflects heat (especially if painted a light colour), while in winter, it acts as an insulating layer that helps retain warmth. The result? Lower energy costs year-round.

Our Step-by-Step Flat Roof Installation Process

Understanding how your new flat roof is installed builds trust and helps you make better decisions.

Here’s what to expect when you work with Alvadac:

1. Initial Consultation & FREE Roof Survey

We start by assessing the current condition of your roof to understand any existing issues. Then, we accurately measure the full roof perimeter to ensure a perfect fit. Finally, we’ll discuss your requirements and provide a clear, no-obligation quote.

2. Surface Preparation

We begin by removing any old roofing materials such as felt or asphalt. Once cleared, we clean and level the roof deck and carefully inspect it for any signs of structural damage that may need attention before installation.

3. Insulation Installation (Optional but Recommended)

To improve thermal performance and comply with Building Regulations, we recommend adding rigid insulation boards. This step significantly boosts energy efficiency and helps keep your property warm in winter and cool in summer.

4. EPDM Membrane Installation

Next, we apply a high-strength bonding adhesive to the deck, then roll out a single, seamless EPDM rubber sheet that’s been cut precisely to fit your roof. The membrane is positioned and smoothed down to ensure a clean, wrinkle-free, and airtight finish.

5. Sealing & Waterproofing

We secure the edges with specialised edge trims, termination bars, and sealants to create a completely watertight perimeter. All joints, vents, skylights, and corners are carefully sealed for maximum protection against leaks.

6. Final Checks & Guarantee Issued

Before we finish, we carry out a full inspection to check the bonding, drainage, and overall finish of your new roof. Once we’re satisfied with the quality, we issue your 20-year installation guarantee for complete peace of mind.

Flat Roof Features & Upgrades

At Alvadac, we go beyond just installing flat roofs, we offer a range of professional finishing touches and upgrades that improve both performance and durability. These features are designed to enhance waterproofing, drainage, and long-term protection, especially for more complex roof designs.

Here are some of the options we provide:

• Wall Outlets – Ideal for parapet roofs, our 100mm x 100mm wall outlets allow for efficient water drainage directly through the wall, preventing pooling and water damage.
• Universal Internal Drain Outlets – For roofs that require internal drainage, these outlets come with adhesive for a secure, watertight seal and reliable long-term performance.
• Trims & Flashings – We stock a complete range of finishing accessories, including Premium Gutter Trims, Upstand Trims, and Wall Plates, ensuring a neat, weatherproof finish around edges, corners, and joints.
• Upstand Detailing – Our guides and install practices also cover detailing around upstands and thresholds. We follow best practices for minimum heights, waterproofing techniques, and membrane placement to meet building standards and keep your roof protected.

These upgrades are integrated into our flat roof installations where needed and can be discussed during your free roof survey. Whether you’re replacing an old system or planning a new build, we’ll make sure your roof is finished to the highest standard.

FAQs

How long does an EPDM flat roof last?

An EPDM rubber roof typically lasts 30 to 50 years when installed properly. It’s highly resistant to weather, UV exposure, and temperature extremes making it one of the most durable flat roofing options available.

What does a flat roof installation cost?

Costs vary depending on the size, insulation needs, and any custom features like drainage outlets or upstands. On average, flat roof installations in the UK range from £70 to £100 per square metre, including materials and labour. We offer free surveys and no-obligation quotes so you can get an accurate price for your specific roof.

Does a flat roof need a slope?

Yes, flat roofs aren’t actually flat. They need a slight slope of at least 1:40 (around 1/4 inch per foot) to allow water to drain properly. We design all our installations to meet or exceed drainage standards and avoid standing water.

Is EPDM roofing low maintenance?

EPDM requires very little maintenance compared to other roofing materials. A quick annual check to clear debris and inspect seals is usually enough. Plus, if repairs are ever needed, they’re fast and simple due to the single-sheet system.

Can you install insulation with a flat roof?

Yes, we highly recommend it. We can install rigid insulation boards (like Kingspan or PIR) beneath the EPDM membrane to improve thermal performance and meet current Building Regulations. This helps reduce heat loss and energy bills.

Is EPDM environmentally friendly?

EPDM is one of the most eco-friendly roofing options available. It requires less energy to produce, is 100% recyclable, and can even help lower your home’s carbon footprint by improving energy efficiency.

Do you offer a guarantee?

Yes, all of our flat roof installations come with a 20-year guarantee, giving you total peace of mind that your roof will stand the test of time.
