CASE STUDY: Retrofit Foam Roof Insulation – the benefits and potential problems!

Retrofit foam roof insulation can offer several benefits, including improved energy efficiency, increased durability, and reduced maintenance costs.  However, there are also some potential problems that can arise with this type of insulation.

  1. Moisture Issues: Foam insulation can trap moisture in the roofing system, leading to mould and rot. If not addressed promptly, this can cause serious damage to the roof structure.
  2. Installation Issues: Improper installation of the foam insulation can lead to gaps, voids, and uneven coverage, which can compromise the insulation's effectiveness.
  3. Adhesion Issues: The foam insulation must adhere properly to the roof surface for optimal performance. If the adhesion fails, the insulation can become loose, leading to air leaks and potential water damage.
  4. Structural Issues: Foam insulation can add significant weight to the roof, which can cause structural problems if the roof is not designed to handle the additional weight.
  5. Maintenance Issues: Maintenance of a foam roof can be more difficult than traditional roofing systems. Regular inspections and maintenance are essential to ensure that the insulation is performing correctly.

Increasingly mortgage providers are declining applications where it is declared that a property has been provided with retrofit foam roof insulation or where the Lender's valuer notes it on inspection.  However, with the prevalence of AVM (Automated Valuation Model) 'desktop' valuations, not all properties are inspected for mortgage applications.
