Spray foam insulation is often promoted as a modern solution for energy efficiency, but many homeowners are unaware of some important facts that could affect their property in the long term. Understanding these points will help you make informed decisions about insulation and, if necessary, its removal. At Hampshire Spray Foam Removal, we work with homeowners across Hampshire to address the risks and complications that spray foam can cause.
1. Spray Foam Can Affect Your Roof’s Breathability
Unlike traditional insulation, spray foam forms an airtight seal, which may trap moisture within the roof structure. This can lead to timber decay, mould growth, and structural issues over time, especially in older properties that rely on natural ventilation.
2. It Can Impact Mortgage and Property Sales
Some lenders are hesitant to approve mortgages on homes with spray foam insulation, particularly if it has been applied to the roof space. This is because it can make inspections difficult and conceal hidden damage. Homeowners often find that removal is essential before selling their property.
3. Not All Spray Foam Is the Same
There are open-cell and closed-cell types of spray foam, each with different properties. While one is softer and more breathable, the other is denser and more rigid. If incorrectly applied or used in the wrong location, either type can create long-term problems.
4. It Can Mask Underlying Roof Damage
Because spray foam is applied directly to the underside of the roof covering, it can hide issues such as leaks, broken tiles, or rotten timbers. This can make routine roof maintenance and inspections much more difficult, potentially allowing damage to worsen unnoticed.
5. Removal Requires Specialist Knowledge and Care
Spray foam cannot simply be peeled off without risking damage to your roof structure. Professional removal, like the service offered by Hampshire Spray Foam Removal, uses safe techniques to protect the roof while restoring proper ventilation and access for maintenance.
6. Energy Efficiency Isn’t Always Improved
While spray foam is marketed as an energy-efficient option, poor installation or unsuitable application can actually lead to problems such as condensation build-up, which may reduce overall thermal performance and lead to costly repairs.
7. Many Homeowners Choose Removal for Peace of Mind
Even if spray foam has not yet caused visible issues, many homeowners decide to remove it to avoid potential complications in the future, especially when preparing to sell their home or secure financing.
In conclusion, spray foam insulation comes with risks that are often overlooked at the point of installation. If you have concerns about the condition of your roof or the impact of existing insulation, Hampshire Spray Foam Removal provides expert assessment and safe removal services to protect your property and maintain its value.
