Why Homeowners Are Considering It
Spray foam loft insulation has become popular in recent years because of its energy efficiency. It creates an airtight seal that helps keep your home warm and lowers energy bills.
But before you decide, it’s important to understand the hidden risks that come with it. Many homeowners discover problems only after installation, which can lead to serious costs in the long run.
The Dangers of Spray Foam Loft Insulation
1. Hidden Damage
Spray foam expands and hardens, covering your roof rafters. While this might sound harmless, it makes it impossible for surveyors to inspect for issues like:
- Rot
- Damp
- Leaks
This means problems could go unnoticed until they become severe.
2. Trapped Moisture
If not installed correctly, spray foam can create an airtight seal that traps moisture inside your roof. This leads to:
- Condensation
- Rotting timbers
- Long-term structural damage
3. Mortgage & Resale Issues
A growing number of mortgage lenders are hesitant to lend on properties with spray foam insulation. Why? Because of the hidden risks and difficulty in assessing roof condition.
This could affect your ability to:
- Remortgage your home
- Sell your property in the future
4. Difficult and Costly Removal
If problems do arise, removing spray foam is no small task. It’s often:
- Expensive
- Time-consuming
- Destructive to your roof structure
Specialist professionals are usually required, adding to the cost.
