Petersfield sits inside the South Downs National Park and carries a great deal of listed property. We remove foam from protected roofs by hand, with consent checked first.

Petersfield is one of Hampshire's more complete Georgian market towns, built around The Square and High Street, and it sits inside the South Downs National Park. A meaningful share of the housing is listed or falls within the conservation area, and the roof structures behind those frontages are often original cut timber, some of it centuries old. National Park designation and listed status both change what is possible. Altering a roof covering, adding ventilation openings or changing the external appearance may need consent before work begins, and on a listed building that is a legal requirement rather than a formality. We raise it at survey and put it in writing. The removal itself is entirely hand-led on protected structures, with no solvent, no heat and nothing abrasive, because timber of that age cannot be replaced like for like if the method damages it. Photographs and moisture readings are logged at every stage, since a surveyor assessing a listed property has to satisfy a lender about structure that is irreplaceable.
Starting work on a listed roof without the right consent creates a far worse problem than the foam did. We check the status of the property at survey, tell you plainly what we think needs permission, and are content to wait while it is obtained. Where we believe a conservation officer or the National Park authority should see the roof before anything happens, we will say so, even though it delays the job. On protected timber the whole strip-out is by hand, worked along the grain, at the pace that method requires.
Our experienced roofing team understands the structure beneath your spray foam insulation, allowing us to remove it safely while protecting roof timbers, tiles and other essential components.
With five years dedicated to spray foam insulation removal, we safely remove both open-cell and closed-cell foam using proven techniques that minimise disruption and help preserve your roof's condition.
We believe in straightforward recommendations, competitive pricing and no hidden costs. Every quotation is clear, with free, no-obligation advice to help you make the right decision for your property.
National Park designation and listed status both shape what is permitted on a Petersfield roof. Start here.
We take it. Most household recycling centres will not accept spray foam in bulk, and moving it yourself without a registered waste carrier licence is against the law. It leaves under our own licence and you get the Waste Transfer Note as proof of where it went.
Most UK jobs run two to five working days. Where yours falls depends on the size of the roof, how much foam is there and how easy the space is to access. A small loft with a thin layer of open-cell foam sits at the short end, a detached roof bonded in closed-cell at the long end.
There is no flat rate we could give you before seeing the roof. Price turns on the foam type, how much of the roof it covers, the condition of the timber underneath and how hard the space is to reach. The survey is free, and the written figure it produces does not move once work starts.
We come out and get into the roof space. That tells us the foam type, how far it spreads, the condition of the timber underneath and how equipment will reach it. You then get a written quotation covering the whole job. The survey is free and carries no obligation.
Yes, by hand and at the pace that requires. No solvent, no heat and nothing abrasive near timber that cannot be replaced like for like. Where we think the conservation officer should see the roof before we touch it, we will say so even though it delays the start.
It can, where the work affects the external appearance of the roof. We check that alongside listed status at survey, and we will wait for consent rather than begin without it.
