Spray Foam Removal in Bury St Edmunds

What we do here

Most people who ring us about spray foam are partway through something that has just stopped moving. A sale, a remortgage, or an equity release application, and the survey has come back mentioning the loft. Nothing about the house has changed, but suddenly there is a problem nobody is explaining properly. That is usually the point at which we get the call, and the first thing worth saying is that it is fixable and you are not the only one.

Why a survey picks it up

Two separate things are going on, and it helps to separate them. The first is what foam does physically: it seals the underside of a roof that was built to breathe, so the moisture ordinary living puts into a house has nowhere to go and ends up held against the timber. The second is what it does to an inspection. A surveyor who cannot see the rafters cannot sign off on them, so even a perfectly sound roof gets reported as unable to be assessed. On the older property in this town that second point tends to be decisive, because a surveyor looking at a building with a few centuries of history in the roof is going to be more cautious about what they cannot see, not less.

Foam on a historic roof

Most guidance you will read about spray foam is written with a post-war house in mind, and it does not entirely fit what is under the tiles in this town. Where a roof is carried on a medieval or early timber frame, the structure is not a component that can be replaced if it is damaged, and a good deal of it will have survived several centuries precisely because it stayed dry and ventilated. Foam undoes that. It is also worth knowing that where a building is listed, spraying foam onto a historic roof structure may not have been permitted in the first place, and removal can occasionally raise questions about what was done and when. We would rather flag that early than have it surface at the worst moment.

How we go about removing it

Everything is hand work. On a frame of this age the timbers are the thing being protected, so nothing mechanical goes near them, and the pace is set by what is underneath rather than by how fast the foam can be got off. Before quoting we establish what type of foam it is, how firmly it has bonded and what condition the structure is in, because those three things decide the job entirely. Residue comes out as well as the bulk, since a partly cleared roof is simply picked up at the next survey and you are back where you started. Once it is out we put the ventilation back, deal properly with any timber that has been sitting damp rather than covering it over, and give you a written record of what was removed and how the roof was left. That last part is what a lender or a surveyor actually wants to see.

Why we travel for this one

We are open about Bury St Edmunds sitting at the outer edge of our area for most work, given we are coming from Dersingham on the West Norfolk coast. Spray foam is the exception we make. It is specialist, there are not many firms who approach it as roofing rather than as cleaning, and it is worth the journey for both of us. Being roofers first matters here, particularly on the older property in this town. The real risk in this work is the damage done getting the foam out, and on a medieval or Georgian roof structure that damage is not something you can simply replace.

What happens to your insulation afterwards

People often assume that taking foam out leaves them with a colder house, and it does not, because the underside of the roof was never the right place for it. Insulation belongs at ceiling level, laid between and over the joists, with the roof space above it ventilated and cold. That is how these buildings were meant to work, and on an older Suffolk roof it matters more than most, because a cold ventilated loft is what keeps centuries-old timber dry. We will go through what you are left with once the foam is out, and if what is already up there is doing its job we will tell you so.

Whether you actually need it done

If you are staying put, your roof is dry and you have no plans to sell or remortgage, there is no urgency, and anyone telling you there is has something to sell. The reasons to act are a sale or remortgage in progress, or signs of damp, staining or a musty loft. If you are unsure, we will come and look and tell you honestly if it can wait. Our main spray foam removal page goes through the process in full. We cover Bury St Edmunds and the west Suffolk villages, and elsewhere in the county Eye and Ipswich. We work across Norfolk, Suffolk, Essex and the wider East of England.
