Felt roofing – the tried and trusted choice

Felt roofing has more than proved its worth over the years. It remains a very popular choice for flat, pitched or curved roofs, particularly on garages and sheds. This is not surprising, as technological advances have resulted in a range of superior quality materials and finishes, addressing the shortcomings of older style felt roofing. These days, if a felt roof is installed and maintained properly, it will prove to be hard-wearing and provide excellent protection from wind and rain. That's why this roofing company specialises in the kind of quality felt roofing Sheffield householders demand. Felt roofing is also the ideal choice for balconies, as it is resistant to damage from footfall. Added to this, it is inexpensive, quick to install and can be repaired easily.

Felt roofing can be installed over wooden, concrete or metal decks. The roof is constructed by building up layers of felt membrane which has been fortified with glass fibre and/or polyester. The felt is laid down in overlapping strips, with bitumen forming a protective, watertight seal. The top layer may come with a choice of finishes. There are several methods of laying the felt, using both 'hot' and 'cold' techniques. Various types of membranes are manufactured using additives to aid the particular installation technique to be used. If you're not sure about any aspect of installation and maintenance, make sure you get the right roofing help and advice.

The traditional installation method uses oxidised bitumen heated in boilers to over 200 degrees centigrade. The technique is known as 'pour and roll', as the hot bitumen is poured out and the membrane is unrolled straight onto it, so that it adheres to the surface. Care must be taken to ensure that all the membrane is coated. If no allowance is made for movement between the membrane and the surface, changes in temperature may cause cracking. To avoid this, the first layer should only be partially bonded.

The torch-on method is very popular, as it is straightforward and effective. The type of membrane used is already coated in bitumen. A special gas torch is directed at the coated side of the membrane, until the bitumen reaches optimal temperature. When the molten bitumen starts to flow onto the surface, the membrane is unrolled gradually, so that strong adhesion is achieved without trapping air underneath. For safety reasons, this technique should not be used on timber decks.

If you want a felt roof that will last, always use qualified professionals who guarantee all their work, like these expert roofers in Liverpool.

'Cold' methods of installing felt roofing involve the use of cold adhesives. The adhesive is brushed all over the surface, and the membrane unrolled onto it. Alternatively, rolls of self-adhesive felt membrane can be used. It is important to make sure that the surface is completely dry and free from dirt, in order to achieve strong adhesion.  

Felt roofs should be checked regularly for signs of leaking or damp ingress. For felt roof repairs as well as customised new roofs, contact this expert and professional roofer in Brent.
