EPDM rubber membranes have transformed flat roofing, offering Hemel Hempstead property owners a modern system that dramatically outperforms traditional built-up felt. Apex UK Roofing is an approved EPDM installer serving Hertfordshire, fitting premium rubber membranes to garages, extensions, dormers, porches, and commercial flat roof areas with guaranteed results.
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane that has become the industry-standard material for high-performance flat roofing. Unlike traditional felt, which deteriorates relatively quickly and is prone to cracking, blistering, and splitting, EPDM remains flexible across a wide temperature range (from minus 45 to plus 130 degrees Celsius), resists UV degradation, and maintains its waterproof integrity for 50 years or more. We install EPDM systems from leading manufacturers including Firestone RubberCover and ClassicBond, using fully bonded adhesive application for a seamless, joint-free finish.
The membrane is laid in a single sheet wherever possible, eliminating the seams and joints that are the main failure point in other flat roof systems. Our EPDM installations in Hemel Hempstead include full deck preparation, insulation upgrades to meet current Building Regulations, new OSB or plywood decking where required, perimeter trim detailing, and proper drainage falls. For properties in Hemel Hempstead, where a large new town in Hertfordshire with extensive post-war housing estates, 1960s tower blocks, and newer developments that present diverse roofing challenges, EPDM is particularly well suited to the local climate, offering exceptional resistance to wind uplift, ponding water, and the freeze-thaw cycles common in the Hertfordshire area.
We survey your Hemel Hempstead property to measure the flat roof area, assess the existing deck condition, and specify the appropriate EPDM system, insulation, and detailing.
We prepare the roof deck by replacing any damaged boards, installing new OSB or plywood where needed, and fitting insulation to meet current thermal regulations.
The rubber membrane is carefully bonded to the prepared deck in a single seamless sheet, with all edges, upstands, and penetrations sealed using purpose-made EPDM trims and adhesives.
We fit perimeter trims, drip edges, and outlet details, then carry out a thorough water test. Your installation is registered with the manufacturer for their guarantee.
EPDM rubber membranes have a proven track record of over 50 years of service, making them one of the longest-lasting flat roof systems available.
Installed in a single sheet with no seams or joints, eliminating the main failure point found in other flat roofing systems.
We are approved installers of Firestone and ClassicBond EPDM, offering manufacturer-backed guarantees of up to 20 years.
Once installed, EPDM requires virtually no maintenance beyond periodic clearing of debris and checking drainage outlets.
EPDM offers the lowest lifetime cost of any flat roofing system, combining affordable installation with exceptional longevity.
EPDM rubber flat roofs have a proven lifespan of 50 years or more when correctly installed. The membrane remains flexible and waterproof throughout its life, resisting UV degradation, frost damage, and thermal movement. We back our installations with manufacturer guarantees of up to 20 years, and many EPDM roofs installed in the 1960s are still performing well today. For your Hemel Hempstead property, an EPDM roof is a genuine fit-and-forget solution.
EPDM is significantly superior to traditional felt in almost every respect. It lasts three to five times longer, remains flexible in extreme temperatures, resists UV and ozone degradation, and is installed in a single seamless sheet that eliminates joint failures. Felt roofs typically need replacing every 10 to 15 years, while EPDM will last 50 years or more. The initial cost is moderately higher, but the lifetime cost is substantially lower, making it the recommended choice for flat roofs across Hertfordshire.
The cost of an EPDM flat roof installation in Hemel Hempstead depends on the size of the area, the condition of the existing deck, whether new insulation is required, and the complexity of the detailing. As a guide, a typical garage flat roof of around 15 square metres costs between 1,500 and 2,500 pounds, while a larger extension roof may cost 3,000 to 6,000 pounds. We provide free, detailed quotations for all EPDM installations across Hertfordshire.
In many cases, yes. If the existing roof deck is structurally sound and level, we can install EPDM directly over it after appropriate preparation. However, if the existing covering is extensively damaged, uneven, or holding moisture, we recommend stripping it back to the deck and starting fresh. This ensures the best possible adhesion and the longest lifespan for your new EPDM roof. We will advise you on the best approach during our free site survey in Hemel Hempstead.
