The work

Why lenders object to foam

Spray foam removal means taking open or closed cell foam back off the underside of the tiles or felt and the rafters. Foam traps moisture in the roof space and makes the timbers impossible to inspect, and lenders have taken a hard line on it, so a house with foam in the loft can be difficult to remortgage or sell even when the roof itself is sound.

Getting the foam out again makes the roof mortgageable, lets the timbers be seen and inspected, and lets the roof space breathe as it was meant to. In most cases it removes the single thing most likely to hold up a sale or a remortgage.

We scrape the foam off the timbers and the felt, clear out the debris, then deal with whatever it was hiding, which is often a felt layer that has been torn or contaminated and needs replacing. You get a written record of the condition of the roof space afterwards, so you have something to show a surveyor or a buyer.

The process

How spray foam removal normally runs

  1. 01

    Inspect the loft

    Which type of foam, how thick, and what it has been sprayed onto. That decides the method and the price.

    Quote

    A written price covering removal, waste and any membrane work that is likely to follow.

  3. 03

    Strip out

    Foam removed from the timbers and the underside of the roof, with the loft sheeted to contain the mess.

  4. 04

    Make good and record

    Membrane repaired or replaced where needed, then a written condition report on the roof space.

Pricing

What moves the price

Every roof is different, so the quote follows a look at yours rather than a figure over the phone. The roof, and the loft where the fault is a leak, both get checked before anything is priced.

The quote you get back is itemised: access, materials, labour and clearing the site. Where the job needs scaffold, that goes in the figure from the start, not added later. The points on the right are what make the biggest difference to where the price lands.

What we look at

  • Whether it is open cell or closed cell foam, as closed cell is far harder to remove
  • The area covered and the thickness of the application
  • Whether the foam was sprayed onto felt, onto a membrane, or directly onto the tiles
  • How much membrane needs replacing once the foam is off
  • Loft access, and how much of the roof space is reachable

FAQs

Things people ask about spray foam removal

Why do lenders object to spray foam?

It stops the roof timbers being inspected and it can trap moisture against them. A surveyor who cannot see the rafters cannot sign them off, and lenders have become unwilling to take that risk.

Can all of it be removed?

The great majority, yes. Closed cell foam bonds hard and some staining or residue can remain on the timber, but the aim is a roof space that a surveyor can inspect. If we think a section cannot be brought back we will say so before starting.

Will the roof need replacing afterwards?

Not usually. What often does need replacing is the felt or membrane the foam was sprayed onto, because removal tears it. The quote flags that as a likely follow-on rather than presenting it as a surprise.
