The
revision (from 2002) of Approved Document L of
the Building Regulations (Conservation of Fuel
and Power) actually came into force in April 2006.
The idea behind the revision was to help implement
the Energy Performance of Buildings Directive
/ EPBD of trying to reduce the energy used in
building (relative to the pre-revised directive)
by between 20% and 28%.
How does this relate to flat roof repair
and refurbishment?
The revision of the building regulations means
that when a flat roof is being refurbished, there
may need to be some work carried out on the insulation
of that roof. The U-Value of roof insulation is
a figure that represents how well it conducts
heat, and the revised regulations have a target
U-Value of 0.25 for existing buildings, and 0.20
for new builds. This means that if your flat roof
insulation doesn't match up to or exceed this
U-Value figure, when your flat roof is repaired,
work will need to be carried out in the insulation
to make sure that it does comply. If there was
no insulation, it will have to be added, and again
should comply with the U-Value figure. There is
obviously likely to be an extra cost implication
here. If your roofing contractor however doesn't
take into account the likely cost of insulation
work in the figure for your flat roof refurbishment
quote, you are not only receiving an essentially
inaccurately low quote, but there could be other
implications:
- The
roofing contractor may not be aware of the revised
Building Regulation, or worse..
- The
roofing contractor may not or carry out the
extra insulation work.
What
happens if the necessary insulation work isn't
carried out?
When
you come to sell your property, you will need
to have a Home Information Pack in which should
be included all the main refurbishment and repair
documentation. A discovery e.g. by the buyers
or their representatives at this stage that the
necessary insulation work hasn't been carried
out could result in delays in the sale, or you
being offered a lower price than you had wanted
for property.
