A favourite on smaller roofs as the pro to this material is if you get it right then this can come with no joins. Meaning a seamless roof and impossible to leak.
EPDM Rubber Roof vs. Roofing Felt
EPDM rubber and torch-on felt roofing systems are the most commonly used materials for residential homes in the UK. If you're still considering your options as to which one to use on your flat roof, here's a short overview comparing the two materials.
Key Factors
- Installation: Even for the keenest of DIY fanatics, installing torch-on felt roofing is not a practical option due to the gas torch and bitumen boiler required. Trained professionals are qualified to take on this sort of job because of the risks involved. This will also add to the price. On the other hand, EPDM membranes are applied cold. They use an adhesive solution which is not only safe but time-efficient. Professional companies are still the best option for this. However, it can be laid down by homeowners, if not to the same high standard.
- Appearance: Felt roofing has a variety of colours available, compared to black and white rubber membranes. However, this must be tempered with the fact that felt’s lack of durability can lead to an unpleasant aesthetic. Felt also doesn’t react well to the growth of algae or moss. The opposite is true of EPDM.
- Durability: EPDM is a far more durable material in comparison to felt and can withstand the more extreme scales of weather across the year. Felt is more susceptible to blistering in hot climates and cracking in the cold. EPDM will not experience these same issues. Rubber roofing is also far more flexible which reduces the risk of leaks and is extremely easy to repair.
- Cost: Felt membranes are a cheaper alternative to EPDM, however, the difference in performance levels mean that rubber membranes offer much better value for money. This means EPDM is more cost-effective in the long run, despite the initial higher costs of purchasing the material.
