Spray foam insulation was sold to many homeowners as a quick way to insulate a roof. Unfortunately, it's caused real headaches — especially for people trying to sell or remortgage. If you've got spray foam in your loft, here's what you need to know.
Why spray foam can be a problem
The biggest issues come down to moisture and visibility:
- It can trap moisture against your roof timbers, risking rot
- It hides the roof structure, so problems can't be inspected
- Many mortgage lenders are wary of lending on foamed roofs
- Surveyors often flag it, which can stall or sink a sale
Many homeowners only discover the problem when a buyer's survey flags the spray foam — right when they're trying to move.
The two types of spray foam
There are open-cell and closed-cell foams, applied in different ways. Both can cause concerns for lenders and surveyors, regardless of how well they were originally installed. The issue is less about the product and more about what it hides and how it affects the roof's ability to breathe.
What can you do about it?
The most reliable solution is usually safe, complete removal — followed by re-insulating with a breathable material that keeps your home warm without the moisture risks.
- Get an honest inspection so you understand what you're dealing with
- Have the foam carefully and fully removed
- Re-insulate with a breathable system suited to your roof
