Flat roof insulation is becoming increasingly important. The better the insulation in your roof then the more energy you save.
Part L of building control sets out the targets that need to be reached for insulation in of new build and retrofit. There are two recognised ways of insulating flat roofs. If the flat roof is part of a new build project it has to be built to part L of building control.

Flat Roofs & Part L of the Building Regulations
What Triggers Part L of the Building Regulations?
On old flat roofs, if you strip the old covering then you trigger part L and you have to insulate the roof to the new regulations, if you already have some insulation in the roof but it’s poor then again this triggers part L. If the flat roof is part of a new build project it has to be built to part L of building regulations.
How Do You Know if You Have a Warm Roof or a Cold Roof?
Generally cold roofs have ventilation and you should see the vents. Older cold roofs may not have vents so look to see if the roof has been raised higher than the surrounding roofs as the roof insulation on a warm roof is on top making it higher.

I’ve been working with Steve Dickinson of London Flat Roofing for almost 10 years and to this day I have not come across anyone with more knowledge on London flat roofs. From leak detection to maintenance, Steve has a wealth of knowledge in all aspects of flat roofing.
Our flat roof was previously installed by cowboy builders. Steve did a fantastic job or un-doing their shoddy work and rectifying all of the issues they had caused. No more leaks and no mess either. The price was fair and they got the job done very quickly.
I came back off holiday to find that the flat roof above my kitchen had been leaking and flooded the house. I called and spoke to Steve who came out the same day and within hours he had identified the leak. The very next day he sent out 2 roofers who fixed the leak. Steve then helped me claim through my insurance policy. Very pleased and grateful for his help.
Steve from London Flat Roofing was very knowledgeable. We had several contractors trying to find the issue with our leaking flat roof prior to getting Steve to look at it. After surveying it with a thermal imaging camera Steve was able to pinpoint the exact location of the leak and fixed it there and then. Very pleased and would definitely recommend to others.
Cold Flat Roof Construction
Warm Roof & Cold Roof Comparison
Insulating a flat roof using the warm roof construction method means you place the roof insulation over the timber decking. Insulating the roof the cold roof method means you place the insulation between the joists with ventilation above the roof insulation.
Warm roof construction is considered to be much more efficient and is an easier build. Cutting pieces of roof insulation between the joist is a skilful job and takes time, unfortunately if the roof insulation is not cut correctly and air can get between then cold bridging can begin.
Warm Flat Roof Construction
Can My Flat Roof be Insulated?
Most old flat roofs can be insulated however sometimes the cost becomes restrictive, take an example of a flat roof that got a bedroom under it and above a balcony opens up onto the flat roof, the step of the door out onto the roof is only 50mm above the existing roof.
In this instance to place roof insulation over the roof to form a warm roof would mean moving the door, and to remove the ceilings down below to add roof insulation and ventilation would devastate the room below. If building control is involved they should be lenient and deem the roof as “hard to insulate” and not enforce the building regulation.
