How to Insulate a Roof Using Spray Foam?

Due to the technical challenges of installation and the associated health and safety concerns, spray foam insulation is highly discouraged for do-it-yourself installations. You should have a survey done to make sure your home is acceptable before choosing spray foam insulation. If so, you can choose between closed-cell and open-cell spray foam.

Closed-cell will entirely seal off your roof area and block moisture; therefore your loft will need to be aired to prevent the build-up of condensation. Open-cell insulation, on the other hand, enables moisture to pass through it thereby rendering your roof breathable. Spray foam is applied to your roof using specialised equipment, providing a uniform covering.


It’s obvious that spray foam roof insulation is one of the finest ways to keep your home secure and pleasant for many years based on the advantages listed above. There are fewer health concerns, longer lifespans, better energy and money-saving solutions, increased comfort, and durability.
