Complete Guide to EPDM Rubber Roofing Installation
EPDM rubber roofing has become one of the most popular flat roofing solutions for residential and commercial properties throughout Ireland. Known for its exceptional durability, weather resistance and long service life, EPDM offers a reliable waterproofing solution that can protect a roof for decades when installed correctly.
At Buildon, we supply a complete range of EPDM roofing products, making it easy to source everything needed for a professional installation from one trusted supplier.
What Is EPDM Rubber Roofing?
EPDM (Ethylene Propylene Diene Monomer) is a highly durable synthetic rubber membrane specifically developed for waterproofing flat and low-slope roofs. Originally introduced for commercial roofing applications, EPDM has become increasingly popular in residential projects due to its long lifespan, flexibility and excellent resistance to weathering.
Unlike traditional felt roofing systems, EPDM remains flexible in both hot and cold temperatures, allowing it to expand and contract naturally as weather conditions change. This flexibility helps reduce the risk of cracking, splitting and premature roof failure.
One of the biggest advantages of EPDM roofing is its resistance to UV radiation, ozone exposure and standing water. These properties make it particularly suitable for the Irish climate, where roofs are regularly exposed to rain, wind and fluctuating temperatures throughout the year.
When installed correctly and maintained properly, an EPDM roof can provide reliable waterproof protection for more than 50 years, making it one of the most cost-effective flat roofing solutions available.
Buildon's range of EPDM Roofing Membranes is available to suit a wide variety of flat roofing applications, providing a durable and long-lasting waterproof finish. EPDM Membranes
Preparing the Roof Surface
Proper preparation is essential before any EPDM membrane is installed. The roof deck should be structurally sound, clean, dry and free from dust, loose materials, oil, grease and sharp objects that could damage the membrane.
Most EPDM systems can be installed over timber decking, OSB boards and suitable insulation boards. Before installation begins, all fixings should be secure and any damaged sections of decking should be replaced.
Taking time to prepare the roof correctly helps ensure optimal adhesive performance and reduces the likelihood of future issues developing within the roofing system.
Positioning the EPDM Membrane
Once the roof surface has been prepared, the EPDM membrane should be carefully rolled out and positioned across the roof area. It is recommended to allow the membrane to relax for a period of time before bonding. This allows any folds or wrinkles caused during packaging and transportation to naturally settle.
Proper positioning at this stage helps ensure a smooth finished appearance and simplifies the installation process.
Buildon's EPDM Roofing Membranes are designed for straightforward installation and provide excellent flexibility for a variety of roof sizes and layouts.
Applying EPDM Adhesives
The membrane is bonded to the roof deck using specialised EPDM adhesives. The choice of adhesive will depend on the roof substrate and the area being bonded.
Horizontal roof areas are typically bonded using deck adhesives, while perimeter details, upstands and vertical surfaces often require contact adhesives to achieve a stronger immediate bond.
Adhesives should always be applied evenly and in accordance with manufacturer recommendations to ensure full membrane adhesion and long-term performance. Care should be taken to avoid trapping air beneath the membrane during installation.
Buildon's range of EPDM Adhesives includes products suitable for securing membranes to timber, insulation boards and vertical surfaces, helping create a strong and reliable bond.
Sealing Seams and Roof Details
Where multiple sheets of membrane are joined together, waterproof seams must be created using compatible primers, seam tapes and sealants. This stage is critical to the overall waterproofing performance of the roof.
Primers prepare the membrane surface for bonding, while seam tapes create strong watertight joins between adjoining sheets. Sealants are often used to protect exposed edges and provide additional weather protection around detailed areas.
Proper seam preparation and installation significantly reduce the risk of water penetration and help ensure the roofing system performs as intended for many years.
Buildon's EPDM Primers, Tapes & Sealants range provides the essential products needed to create secure waterproof seals around overlaps, roof edges and complex detailing.

Installing Flashings Around Roof Features
Every flat roof contains areas that require additional waterproof detailing. Pipes, vents, skylights, rooflights and wall junctions are common examples of locations where flashings are required.
EPDM flashings provide an effective solution for sealing these complex areas while maintaining the flexibility and durability of the overall roofing system. Pre-formed flashings and pipe boots can also help simplify installation and improve consistency.
Correct flashing installation is vital for preventing leaks around roof penetrations, which are often among the most vulnerable areas on any flat roof.
Buildon's EPDM Flashings range includes solutions for corners, penetrations and other roof details, helping achieve a professional and long-lasting finish. EPDM Flashings Products
Finishing Roof Edges
Roof perimeters must be securely finished to protect the membrane from wind uplift and water ingress. Edge trims and drip edge systems help secure the membrane while providing a neat and professional appearance.
In addition to improving aesthetics, edge trims help direct water away from the roof structure and protect exposed edges from weather-related damage.
Selecting quality edge detailing products can significantly improve the overall appearance and performance of the finished roof.
Buildon's EPDM Trims & Edging products are designed to complement EPDM roofing systems and deliver a clean, professional finish on every project.
Ensuring Effective Roof Drainage
Even the highest quality roofing membrane requires effective drainage to perform correctly. Flat roofs should always be designed with suitable falls to direct rainwater towards outlets and drainage points.
Poor drainage can lead to standing water, increased loading on the roof structure and unnecessary stress on roofing materials over time. Properly positioned outlets and drainage components help maintain efficient water flow and support the long-term performance of the roof.
Buildon's EPDM Roof Drainage range includes outlets and drainage solutions designed to help direct rainwater safely away from the roof surface and maintain efficient water flow. EPDM Roof Drainage Products
Using the Right Tools
Using the correct tools helps improve installation quality, reduce installation time and achieve more consistent results. Rollers, brushes, seam rollers and other specialist roofing tools are commonly used throughout the installation process.
Applying the correct pressure to seams and flashings is particularly important for achieving reliable adhesion and waterproofing performance.
