Stripping an old felt roof laid onto decking
The
roof stripping is progressing very well. The
previous roofing company had laid this roof
directly onto the decking. They laid 3 layers of
mineral felt using hot bitumen. Note the little dots on the
decking, indicating they opted to use a perforated 1st coat
of felt. The idea behind this is that the 2nd coat
of felt will only partially bond to the decking.
This ensures that when it fails, the next roofer can remove the old
felt without having to hack away at the
decking. This can be a common problem, because when roofers
don't follow manufacturers' instructions, and fully bond the
roof, the cost of removing the old roof
covering could be considerably more expensive.
Most of the felt is up now. The green bags have
been pushed down vent holes to stop any debris from making a
blockage. Note the old skylights. Here is a link that shows us
cleaning off the
skylights. Also take a look at the state of the wall by the
chimney pots at the left of this picture, and you can see how we
finished them off here -
