Spray Foam Removal in Allerton, Liverpool

Why Allerton lofts so often come up at survey stage

Allerton is largely made up of family houses: inter-war semis with hipped, tiled roofs, plus larger Edwardian and Victorian properties nearer Calderstones Park and along the roads off Allerton Road. Homes like these change hands steadily, and each sale brings a valuer into the loft. When that valuer finds the rafters coated in foam, they cannot see the condition of the timber or the felt behind it, and the report usually says so.

That is often the first time an owner hears that the foam is a problem. It may have been installed years ago by a previous owner, sold on the promise of lower heating bills. Whatever the history, the practical question is the same: can the roof structure be seen and assessed? Removing the foam answers that.

Hipped roofs and what they mean for the job

A hipped roof slopes on three or four sides rather than ending in a gable wall. In a typical Allerton semi that means more roof surface to clear for the floor area, shorter rafters near the hips, and tight corners where the slopes meet. Foam sprayed into those corners is awkward to reach and tends to be thicker, because installers often overlapped passes there.

We plan each hipped loft in sections, working from the crown down to the eaves and taking particular care at the hip rafters and valleys, where the roof covering is most vulnerable. Where the foam has been sprayed straight onto the back of tiles or old felt, it comes away slowly and in small pieces. This is why we never quote by floor area alone.

What we look at on an Allerton visit

• Type of foamSoft open-cell foam peels and cuts more readily; rigid closed-cell foam bonds hard and takes longer. See our closed-cell spray foam removal page for why.
• Roof coveringWhether there is felt or a membrane behind the foam, or whether it was sprayed directly onto tiles.
• Eaves ventilationWhether the foam has sealed the gaps at the eaves that let air move through the roof space.
• Access and storageHatch size, existing boarding and anything stored in the loft that needs moving first.

From that visit we give you a written quote and an idea of how long the work should take. Many Allerton lofts are a couple of days’ work, but a large detached roof or heavy closed-cell foam can take longer.

Removal, step by step

1. We protect the landing, the loft hatch and the route through the house.
2. The foam is cut back from the rafters and roof underside by hand with scrapers and saws.
3. All waste is bagged in the loft and carried out for proper disposal.
4. The rafters and battens are cleaned back so they are visible again.
5. We moisture-check the timbers and photograph the condition of the roof underside.
6. You receive a written report setting out what we found and anything that needs a roofer.

If the felt or battens are damaged once exposed, we say so plainly rather than covering it up. Most owners then want the loft insulated properly at ceiling level, which we cover on our re-insulating after removal page.

Selling or remortgaging in L18?

If a buyer’s survey or a valuation has flagged the foam, tell us the dates you are working to when you call. We can often arrange to look at the loft quickly, and the report we produce is written to be passed straight to the people who asked for it. We cannot say what any lender will decide, because each one sets its own policy, but clearing the foam and documenting the roof gives them something concrete to assess. Our spray foam and mortgages page explains the usual sticking points.

Allerton sits between several areas we visit regularly. We also work in Mossley Hill to the north-west, Woolton to the east and Childwall to the north-east. For an overview of how we work across the city, see our page on spray foam removal in Liverpool.
