What is EPDM rubber roofing?

Fast and easy flat roofing system for DIY and trade installation

EPDM is a rubber-polymer based roofing membrane, fast and easy to install using cold-applied methods and water-based adhesives. Manufactured by Firestone in the U.S., EPDM sheet membrane has consistently proven high performance at every level all over the world in different climates. Essentially, EPDM rubber roofing membrane is composed from EPDM polymers and carbon black, giving it superior resistance to ozone and UV radiation and waterproofing qualities unmatched by any other roofing membrane.

EPDM rubber roofing systems offer flexibility and high performance with a life expectancy like no other membrane at more than 50 years. PermaroofUK Ltd, as the UKs largest Firestone-licenced importer and distributor, introduced the EPDM flat roof kit to make this revolutionary roofing system more accessible for the DIY market.

Why choose rubber roofing membrane over traditional materials?

Over time, old membranes and traditional flat roof coverings become worn and tired. Traditional felt roofing can degrade quickly, in just a few years in some cases, depending upon the climate, location, use and typical weather patterns. Different types of roofing degrade at varying rates, but none have the staying power of modern rubber roofing.

When typical, traditional materials, such as bituminous or asphalt felt (or tar paper) wear and weather, they become brittle, bubble and eventually crack, leading to water ingress, particularly where there are joins or old repairs. Rubber roofing membrane is manufactured and behaves differently to traditional roofing felt. With impressive resistance to UV radiation and ozone, EPDM is not adversely affected by temperature fluctuations. It remains flexible down to -45° and has the capacity to elongate over 300% to accommodate even severe building movement.

Once water gets under the old felt, or seeps into cracks in concrete, the roof deck will begin to saturate, which will lead to rot in the deck and supporting woodwork or metalwork. Before long, damage can affect the entire flat roof and it will need to be completely replaced or made safe. There is every chance that damage to goods or decoration will occur as a result, and this is when we begin to realise the true cost of not considering modern roofing alternatives.

Rubber roofing membrane is fitted typically in a single sheet in sizes up to 12.5m x 30m. This results in no more joins on most flat roofing projects and far fewer on even the largest jobs. Joins and seams are the most common vulnerable points of failure on roofing, so this in itself is a benefit of choosing modern rubber roofing.

EPDM Rubber Roofing Frequently Asked Questions

How can you tell if your flat roof needs replacing?

Visual inspection is critical at least once every three months (or after a storm or bad weather) to look out for instances of ponding, bubbling of membranes, tears or cracks or for any area of the roof that may have been damaged. If you see any of these issues, your roofing membrane probably needs replacing. Keep an eye on the interiors of all flat roofing, whether it’s the garage, garden office or home extension. The first sign of water damage is a signal that the roof has been leaking for some time and requires immediate attention.

Is rubber roofing membrane suitable for DIY?

One of the greatest advantages of rubber roofing systems is the ease of application, making them suitable for skilled DIYers. Using few tools and cold, water-based roofing adhesive in the main, EPDM rubber is safer than bituminous methods. As EPDM is laid in a single sheet typically, there a no joins to create vulnerabilities in the roofing material.

My flat roof doesn’t look flat. Is that OK?

Flat roofing is never truly flat but has a specified gradient to allow water to run off with no chance of ponding. The regulations vary by region and country, but for reference, the minimum slope to allow for water run-off is 1%, but the regulation may specify 2% or more. Taking advice from a professional flat roof design company, or from an independent surveyor is a good place to start.

How long do EPDM rubber roof membranes last?

EPDM rubber roof membrane carries a 50-year life expectancy once installed correctly. Today, the latest in EPDM flat roof membranes means that not only is waterproofing significantly improved when compared to more traditional coverings, such as roofing felt, but in terms of longevity, EPDM is unmatched.

Rubber roofing is more expensive than felt. Is it worth it?

Buying a membrane or flat roof system with better lasting and performance qualities than felt really does make a lot of sense. Initially, the investment can be more costly than the application of felt, but money can be saved with these types of systems, as they are ideal for a DIY enthusiast in kit-form, potentially saving £££s in professional installation fees for smaller jobs such as shed or garage roofing.

What does ponding on a flat roof mean?

If your roof looks like it has ponds across the surface of it after heavy rain, this is a sign of an issue with drainage. Another giveaway of ponding is the appearance circles of algae or dirt on the surface of the flat roof, indicating that ponding is occurring. Ponding can also indicate that the structure of the roof deck itself is affected, as sagging of the roof structure creates an uneven surface that allows water to pool. It may also be happening because of poor flat roof design, as the roof deck should be designed to have an accurate slope to enable water to drain away effectively. Whatever the cause, ponding issues should be addressed quickly after discovery, as ignoring such problems can lead to water ingress and subsequent leaking, which can cause expensive damage to both the remaining flat roof and the interior of the building.

Can you use rubber roofing membrane for green roofs?

EPDM rubber membrane is ideal for green roof projects, but the addition of insulation layers is critical to avoid instances of membrane damage, which could then lead to water ingress. The waterproofing capacity of EPDM, and the expected lifespan of more than 50 years makes it the perfect choice for your green roof. Find out more in the green roof division.
