We remove spray foam from lofts across Aigburth, mainly in L17 and the Aigburth end of L19. Because so many homes here are Victorian, with slate roofs and timbers well over a century old, the priority is getting the foam off without disturbing the slates and then giving a clear account of the timber underneath. We do that by hand and provide a photographic report afterwards.
Old roofs, modern foam: the Aigburth problem
Aigburth grew up in the nineteenth century, with large villas around Sefton Park and towards the river at Otterspool, and rows of terraced houses around Lark Lane and off Aigburth Road. Many of those villas have since been divided into flats. Their roofs were built to breathe: slate laid on battens, often with no felt at all, so that air could move through the roof and dry out any moisture.
Spray foam works against that. When it is sprayed directly onto the underside of slates and battens, it seals the gaps that let the roof dry. If water then gets in through a slipped slate or a failed joint, it can sit against the timber with nowhere to go. A valuer cannot see whether that has happened, which is why foam in an Aigburth loft so often triggers a request for further investigation.
Slate roofs need a gentle hand
Slates are thin and held by nails that may be decades old. Pulling hard at foam bonded to their underside can loosen them. We remove the foam in small sections, cutting close to the rafters first and then easing it away from the slates and battens, so the roof covering is disturbed as little as possible. Closed-cell foam, which sets rigid and grips tightly, needs the most patience; you can read why on our closed-cell removal page.
Where a slate or batten is already loose or rotten when the foam comes off, we record it and photograph it. Repairs to the roof covering are roofing work, and we will say clearly what we found so you can get the right trade in.
Flats and shared roofs
If you own a flat in a converted Aigburth villa, the roof is often shared with other leaseholders or managed by a freeholder or management company. Before we can remove foam from a shared loft, the people responsible for the roof need to agree. We are happy to talk to managing agents, explain what removal involves and provide a quote that can be circulated. Our spray foam survey and inspection is often a sensible first step here, because it gives everyone the same information before anyone commits.
Riverside weather
Homes near the Mersey and Otterspool Promenade take more wind and driving rain than those further inland. That makes the condition of the roof covering more important, not less. Once foam is cleared we can see whether rain has been getting in, whether timbers are damp, and whether ventilation at the eaves has been blocked. All of that goes into our report.
How an Aigburth job usually runs
| Stage | What happens |
|---|---|
| First call | We ask about the property, the foam if you know anything about it, and whether a sale or remortgage is pending. |
| Visit | We look at the loft, the roof covering behind the foam, access and any shared-roof issues. |
| Quote | A written quote and an expected duration, usually a couple of days for a typical terrace. |
| Removal | Hand removal, bagging and disposal, cleaning back the timbers. |
| Report | Moisture readings, photographs and notes on anything needing a roofer. |
After removal, most owners want the loft insulated again at ceiling level. We explain the options on our re-insulation page. If you want a fuller picture of the service, our local spray foam removal service page covers the whole process.

Frequently asked questions
Which Aigburth postcodes do you cover?
We cover the whole of L17 and the parts of L19 that are generally counted as Aigburth, including the streets towards the river. We also work in the neighbouring districts, so if your postcode is on the boundary, give us a call and we will confirm.
Can you remove foam from a Victorian slate roof without damaging the slates?
That is exactly how we approach it. We cut the foam away in small sections and ease it off the slates rather than pulling it, which keeps disturbance to a minimum. If any slates or battens were already loose or decayed, we record and photograph them so you know what a roofer needs to look at.
I own a flat in a converted house. Can I get the foam removed?
Usually the roof is shared or controlled by a freeholder or management company, so they need to agree first. We can explain the work to them, provide a quote that can be shared between owners, and carry out an inspection so everyone has the same facts before deciding.
Is spray foam worse on an unfelted roof?
It can be. Many older Aigburth roofs have slates laid on battens with no felt, relying on airflow to stay dry. Foam sprayed directly onto them blocks that airflow and can hold moisture against timber. Removal lets the roof breathe again and allows its condition to be seen.
How much notice do you need before a sale completes?
Call as soon as the survey flags the foam. We will try to arrange a visit promptly and tell you how long the removal is likely to take, so your solicitor and buyer can plan. The earlier we know, the easier it is to fit around your dates.
