Guidance on the Problems associated with Spray Foam
In the News
There seems to be ever-increasing instances of scams relating to spray foam taking place with these rogue firms especially targeting the elderly.
Spray Foam roof Insulation is death to your Roof
It can be a fire hazard It destroys your roof It massively devalues your home, you might not be able to borrow against your home or sell your home
Spray Foam insulation is a liquid foam that is sprayed onto the underside of the roof pitches to provide an extra layer of insulation to the property.
However, for all the good that it can do, it also causes issues with some lenders. The problem in this case is that many lenders of mortgages and equity release companies refuse to accept homes with spray foam insulation as suitable security for a mortgage or lending. Many lenders are reluctant to lend on a property that has this type of insulation installed to the roof. Many properties have to have the roof replaced in order for the property to meet the acceptable standards for the lender. This means that the existing roof may need to be taken off and everything needed to be new, the timbers, felt and all the tiles. This is at a massive financial cost to the owner, not to mention the emotional rollercoaster that the homeowner goes through all because there is spray foam insulation present but www.sprayfoamremoval.co.uk can help
Now, this doesn’t mean that spray foam insulation is a bad thing
it has been used for more than 30 years in the UK and many lenders still deem it an acceptable improvement but, if more and more banks and lenders are refusing to lend or give mortgages on properties with spray foam insulation then it may prove to be more and more difficult to sell your property or to re-mortgage in the future.
In the long-term, this may cause the value of your property to decrease as there could be a situation where there is a lack of available funding to a possible buyer unless the property undergoes an expensive roof replacement being needed which will be at the cost of the owners either directly or through the agreed purchase price of the sale.
Is your Spray Foam Insulation Flammable?
Spray Foam Insulation and Dampness Problems
Should condensation be an issue, or dampness gets in, the result could damage roof trusses, battens, and purlins. All of which could start to rot. There have been reports of properties having very wet roof timbers due to spray foam insulation having been installed. The result is a degradation in your roof’s condition.
This occurred when either closed or open cell spray foam insulation was installed. In short, it proves that spray foam insulation is not as breathable as reported. Another consideration that could negatively impact your roof is when installers do not carry out the job thoroughly. This happens when installers fail to fill cavities which creates a much higher risk of water damage. All too often, owners do not realise the amount of damage done until it becomes a serious problem.
The Difference between Closed Cell Spray Foam Insulation and Open Cell Spray Foam Insulation
Closed Cell Spray Foam
Closed cell spray foam differs from open cell because it can help support a roof structure. The reason being that when it sets closed cell spray foam is rigid, and as a result if a property’s roof is not in the best condition, the insulation can add extra support.
The reason closed cell spray foam is solid when it sets is because it contains many pockets of gas. These pockets in turn slows down the movement of heat through the foam. However, a room or loft must be well-ventilated when using closed spray foam because it forms a barrier to moisture. If not well-ventilated, condensation builds up causing all sorts of problems.
Open Cell Spray Foam
Open cell spray foam on the other hand, is less dense and be compressed using nothing more than your hands. As such, open cell spray foam is not good when used to support a roof structure. Nor is the foam any good as an insulator which means you have to install a much thicker layer to achieve required results. Thicker layers are the only way you will obtain the same level of insulation provided by closed cell spray foam. But in the long-term neither are a good choice should you wish to sell or re-mortgage a property. You may find spray foam insulation removal is the most viable option.
Spray Foam Insulation – The Downsides
If something goes wrong and it has to be removed it is EXTREMELY difficult and labour intensive to remove.
Most mortgage companies don’t like it, so it might be an idea to run it by yours before you install it. Even if they’re ok with it, will the mortgage company your buyer uses be ok with it if you decide to sell your house in the future?
Dampness getting in or condensation being caused can lead to rotting of roof trusses and battens and purlins.
In the past few months
We’ve seen and documented a number of cases of very wet roof timbers, with degradation of the roof as a result of sprayed foam insulation. These were both open and closed cell foam – and all had effectively destroyed the roof they were sprayed in. Spray Foam Insulation is not as breathable as claimed. www.sprayfoamremoval.co.uk have proof that Spray Foam Insulation can cause major problems with roofing. We have spoken to numerous purchasers who walk away from deals after finding Spray Foam Insulation sprayed in the roof.
