FLAT ROOFING

THE COMPLETE GUIDE TO FLAT ROOFING

 

Most of the flat roofing we undertake these days is with EPDM (rubber membrane) - its popularity has soared in recent years for the very simple reason that  EPDM flat roofing material has proved itself to be vastly superior in every respect to the traditional felt alternative. EPDM flat roofing is cost-effective and ideal for almost all types of flat roof.

 

EPDM Rubber Roof vs. Roofing Felt

EPDM rubber and felt roofing systems are the most commonly used materials for flat roofing in residential and commercial properties 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

  • Durability: EPDM is far more durable than felt and can withstand the more extreme scales of weather across the year. Felt is susceptible to blistering in hot weather and cracking in the cold. EPDM will not experience these issues. Rubber roofing is also far more flexible which reduces the risk of leaks, and in case of accidental damage it is extremely easy and cost-effective to repair.

 

  • Cost: Felt membranes are a cheaper alternative to EPDM, but felt roofing systems consist of several layers, while EPDM systems consist of a single ultra-durable membrane, so a greater quantity of materials is needed for felt systems. The much higher performance levels of EPDM rubber means that it offers much better value for money, so EPDM is cost-effective. In addition, due to the need for naked-flame gas torches to install felt, contractors’ insurance costs are much higher, resulting in the comparative cost of EPDM being very affordable. 

 

  • Installation: Installing torch-on felt roofing necessitates the use of naked flame gas torches and bitumen boilers with the associated fire risks, to lay several layers of felt. The procedure is time and labour intensive. On the other hand, EPDM membranes are applied cold. They use a specialist adhesive solution which is not only safe but time efficient too. 

The skill and attention to detail that is the hallmark of our highly trained professionals work ethic can be counted on to guarantee a neat, environmentally friendly, long-lasting and leak-free roof. 

 

  • 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 quickly attracts the growth of algae and moss. The fast degradation of the surface of felt means that any repairs cannot blend-in, and they look patchy. The opposite is true of EPDM.

What is EPDM rubber roofing?

Ethylene Polypropylene Diene Monomer (EPDM) is one of the most versatile rubber roofing options on the market. Considered to be one of the best materials for flat roofs, rubber is a popular choice for domestic and commercial applications thanks to its ability to withstand extreme weather conditions. It requires little maintenance, is tear-resistant and has good insulation properties, which all contribute to its long lifespan.

Unlike poorer quality materials previously used for flat roofs, EPDM is highly weatherproof, protecting your home from the elements. It’s also resistant to algae meaning you won’t have to worry about unsightly and damaging moss growth which other types of flat roofs. 

 

How long does EPDM last?

The expected lifespan of an EPDM rubber roof is over 50 years. That’s more than half a century of minimal maintenance thanks to its highly durable properties. EPDM manufacturers offer a warranty of between 20 and 30 years.
