Discover How Insulating Your Flat Roof Can Save You Money and Keep You Warm, No Matter How Cold It Gets!
“Are You Fed Up With The Room Under Your Flat Roof Always Being Colder Than The Rest Of Your House?”
I’m sure you don’t need me to tell you that owning a flat roof comes with its own set of challenges, one of the biggest being, that most flat roofs built pre 1990 are seriously lacking in any significant insulation which makes them terrible at keeping your heat in, making your room underneath cold and expensive to heat, but it gets worse!
“How Your Flat Roof Could Be Pumping Cold Air Into Your Home And Turning It Into An Expensive Fridge”
Even if your flat roof has some insulation (typically 4 inches or 100 mm) because of the way flat roofs are built with insulation placed between the joists, now if it was built after 1986 they realized that the space between the top of the insulation and the timber sub-deck needed to be ventilated to stop any condensation forming and rotting the deck. (see diagram below)
Typical Post 1986 “Cold Roof” Construction
The problem with this way of insulating is that you MUST have an air gap of at least 2 inches (50mm) with a constant flow of circulating air above the insulation and below the sub-deck to get rid of the potential condensation. This uses the same principle as when you clear your car windscreen by blowing air across it to get rid of the condensation.
So this method of construction solved the condensation problems flat roofs were having before 1986 but created a very inefficient flat roof in the process.
“A Lot of Flat Roofs Aren’t Ventilated Properly & Why Hidden Condensation Could Be Damaging Your Roof”
It’s worth checking your roof to see if in fact it has got any effective ventilation because I see lots of flat roofs that don’t especially built before 1986 and some after this time as the regulations took time to implement.
Did you know the average family produces 20 pints (5 gallons or approximately 12 litres) of moisture every day. Think of it as two and a half builders buckets full of water and you will see the scale of the problem your home has to cope with. A single tumble dryer produces approx 7.5 litres of water a day to add to this, so kitchens, bathrooms and utility rooms are very high risk.
“What You Can’t See & Don’t Know About CAN Hurt You”
Your roof may well suffer with hidden condensation problems that can rot the timber structure and cause unseen mould and spore build up that can in the worst cases cause a complete collapse of the roof structure as well as potential health issues.
“Make Sure Any Contractor You Use Is Up to Speed With Document L1b”
Because, since April 2006, if you’re refurbishing 50% or more of your existing flat roof, you’ve been required by law to upgrade the insulation in your flat roof in order to comply with the Government’s “Conservation of Fuel & Power in existing dwellings” Part L1b regulations. (If you want some light bedtime reading you can download a copy here)
Also make sure, if they offer you a “warm roof” by bolting insulation on top of your existing roof, that they are aware of how not to cause interstitial condensation by not fitting deep enough insulation.
“Even The Government Know This And Want You To Improve Your Flat Roofing Insulation Properly”
To help take some of the additional pain out of this additional cost, the Government have set up an incentive to encourage you to comply and help them meet their CO2 emission targets by reducing the amount of VAT you need to pay to just 5% on this type of work, including any work required as a result of your insulation upgrade!
“Using A Competent Roofer Can Save You Money And Avoid A £5000 Fine!”
To make sure you get the very best and latest information relating to ALL of the new building regulations the Government have allowed the NFRC (National Federation Of Roofing Contractors) to set up something called the “Competent Roofer Scheme”.
“County Flat Roofing’s EcoWarm Flat Roofing System Solves ALL Your Flat Roofing Problems In One Go “
All of the potential pitfalls and problems described above can be overcome by upgrading your flat roof using our EcoWarm Flat Roofing System.
For the last 5 years or so most new build flat roofs are constructed using a “Warm Roof System”, simply put; this involves fixing solid insulation boards to the top of the flat roofing deck and by doing this you completely eliminate the need to ventilate between the joists and therefore cold air circulating and plunging into your home causing draughts and cold spots.
Warm Roof Construction
So because of this you DON’T get unwanted cold air circulating into your home making it cold and draughty as we block up all of the existing vents (if you have them).
Your existing roof is encapsulated with 5 inches of (120 mm) of solid polyisocyanurate (PIR) insulation boards as standard along with the required vapour control layer.

“We Give You 50% More Insulation Than Is Required To Achieve The Target U Values And STOP Interstitial Condensation”
In most cases the required U value can be achieved with about 80 mm of insulation, however using this depth of insulation can lead to an interstitial condensation risk if you’ve already got insulation between the joists, so in consultation with Kingspan they have calculated 120mm to be the required solution.
