What is a built up felt roof?
A built up felt roof
is an established method of weather proofing roofs, normally flat
roofs, by using more than one layer of bituminous roofing felt which
is bonded to the previous layer. Three layers are usually laid with
chippings which is layed on top to protect the felt from the sun, or
a mineral cap sheet is sometimes used instead.
What is felt and are there different types?
Felt
is what keeps the rain out; it comes in rolls of 1 metre wide and
in various lengths from 8 meters up to 20 metres depending on the
type and manufacturer. The felt is made up of a mat of fibres coated
on both sides with a bituminous coating. The felt surface is then finished
with a light sand which stops the felt from sticking to itself. There
are lots of different types of felt for various types of applications;
the main differences are lay in the various fibre mats which are
used as well as the finished surface.Modern felts generally use either
a glass fibre mat or for more high performance polyester mats. The
finished surfaces are either made of sand or slate granules for a mineral
finish. A mineral finish can also come in a variety
of colours, usually green, blue/grey, red/brown or white. These colours,
other than green are only available on the high performance felts.
The mineral finished felt is commonly used for edging detail work and
as a cap sheet if chippings are not required.
Advantages of High Performance felt
The main advantage
of High Performance felt is it's life span. Any well designed, well
carried out felted roof should last roughly about 15 years. But for
an extra quarter if the price, the same roof with High Performance
felt should last twice as long! (roughly 30 years).

roofing systems. All our roofing is covered under warranties and
