How does this effect my flat roof repair and refurbishment?
Since 2006 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.
The only way this can be achieved is to remove the old felt, remove the decking and then remove the old insulation quilt. This CANNOT be left in place if fitted otherwise you will have condensation issues within a few years. This can be confirmed by contacting kingspan. Of course if you have none in place then it is not an issue, but please dont be fooled by someone telling you it is ok to ignore, this is just to ensure they are the cheaper quote and get the works, not in your interest.Also please bear in mind that some works may be required to the Fascias etc. Some companys insist that this is not required and that only 50mm insulation is fitted, just as well throw a towel over the roof THIS IS INCORRECT and does not comply to any regulation or give you any u value worth anything, they are obtaining work cheaply and are not being honest with you, next question if thats the case how good a job have you had.
And anything less than 100mm does NOT comply.
How have none of the roofing EXPERTS on this site ever mentioned this
