About this service

What Roof Spray Foam Removal in Barnstaple Involves

Roof Spray Foam Removal in Barnstaple means mechanically cutting out cured polyurethane foam from the underside of your roof covering, then cleaning the rafters, purlins and felt back to bare timber. Open cell foam comes out with a spray foam removal saw and oscillating multi-tool; closed cell foam is denser, so we often switch to dry ice blasting or sand blasting equipment to avoid gouging the wood. Every rafter is then checked with a moisture meter and thermal imaging camera before we sign the roof space off.

Most Barnstaple jobs we see are foam sprayed between 2005 and 2015 on older North Devon properties, and the problem shows up when you try to sell, remortgage or insure. Lenders flag it because foam hides roof timber rot, traps moisture and blocks the ventilation gap that slate and tile roofs rely on. If you have been searching for roofing spray foam removal near me Barnstaple, that is exactly the work we do, and we do it without removing your roof covering in most cases.

What's included

What Our Roof Spray Foam Removal Includes

Every removal we quote includes the full strip-out, timber cleaning, ventilation reinstatement and certification. If your roof needs new felt, battens or a section of timber replaced, we price that at survey so there are no surprises once work begins.

✓

Full Foam Strip-Out

Complete removal of open cell or closed cell foam from rafters, purlins, battens and roof underside, using a spray foam removal saw, oscillating multi-tool, dry ice blasting or sand blasting equipment as the substrate requires.

✓

Timber Cleaning and Treatment

We wire-brush residual foam, apply fungicidal treatment to any early rot, and replace timbers that have gone soft. Every rafter is checked with a moisture meter before we move on to reinstatement.

✓

Ventilation Reinstatement

Foam usually blocks the eaves gap that slate and tile roofs depend on. We clear it, check the ridge ventilation and confirm airflow is restored, which is the single biggest factor in stopping the damp coming back.

✓

Dust Containment and Clean-Up

Protective sheeting, sealed loft hatch, air scrubbers and negative air machines run throughout the job. We vacuum as we cut and leave the loft space clean, with all foam waste bagged and removed from site.

✓

Removal Certificate and Photo Pack

You receive a written removal certificate, before-and-after photographs and moisture readings for every rafter, formatted for lenders, surveyors and valuers. Most customers have the pack within 24 hours of final inspection.

✓

Breathable Insulation Reinstatement

Once the foam is out we specify and fit breathable insulation, usually mineral wool or a breathable board, to bring the roof back to a sensible thermal standard without recreating the moisture trap that caused the problem.

How it works

How Our Roof Foam Removal Process Works

01

Survey and Test

We attend within 48 hours, measure the foam depth, identify whether it is open cell or closed cell, and take moisture readings on every rafter. You get a written report with photographs and a fixed price, usually the same day. There is no charge for the survey.

02

Contain the Loft

On day one we lay protective sheeting, seal the loft hatch and set up negative air machines and air scrubbers. This keeps foam dust and any isocyanate residue out of your bedrooms and kitchen. Expect the loft to be out of use for the duration.

03

Cut and Extract Foam

Foam comes out with a spray foam removal saw, oscillating multi-tool and, on stubborn closed cell sections, dry ice blasting. An industrial vacuum runs continuously. A typical three-bedroom semi takes two to three days; a large detached barn conversion can run to five.

04

Clean and Treat Timbers

We wire-brush residual foam from the rafters, treat any early timber rot with a fungicidal wash, and replace sections that have gone soft. Every timber is re-checked with a moisture meter. This stage usually adds one day to the schedule.

05

Ventilate and Certify

We reinstate the ventilation path at eaves and ridge, fit breathable insulation to spec, then issue your removal certificate and photographic pack. Most customers receive the paperwork within 24 hours of the final inspection, ready to send straight to their lender.

Tools & methods

Tools and Methods We Use

Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.

Spray foam removal saw

Cuts cured open cell and closed cell foam into manageable blocks without tearing the felt or battens underneath. Our first tool on almost every Barnstaple job.

Oscillating multi-tool

Gets into rafter bays, around purlins and along the eaves where a saw will not fit. Used to trim residual foam back to bare timber before cleaning.

Dry ice blasting machine

Removes closed cell foam from delicate or historic timbers without abrasion or added moisture. Our preferred method on listed and older Barnstaple properties.

Sand blasting equipment

Strips stubborn foam residue from brickwork and heavy timber where hand tools cannot reach. Always run inside full containment with negative air machines.

Industrial vacuum and air scrubber

Captures foam dust at the point of cutting and filters the loft air continuously. Paired with a negative air machine to keep dust out of the rest of the house.

Thermal imaging camera and moisture meter

Confirms where moisture is sitting in the roof structure and verifies that timbers are dry before we sign the job off and issue the certificate.

Real results

Before and after.

Mortgage Hold Cleared in Pilton

Before

A three-bedroom Victorian terrace in Pilton had Icynene foam sprayed across the entire roof underside in 2009. The buyer's lender refused to proceed, the sale collapsed, and the owner was facing a second round of viewings with no idea how to fix it.

After

We stripped the foam in three days, treated two rafters with early rot, cleared the blocked eaves gap and refitted breathable insulation. Moisture readings returned to normal on every timber, and the removal certificate was issued within 24 hours. The sale completed three weeks later.

Closed Cell Foam Out of a Roundswell Semi

Before

A four-bedroom semi in Roundswell had closed cell foam sprayed directly onto tile undersides in 2013. The owner noticed a damp smell in the back bedroom and feared a full roof strip and re-cover costing over ten thousand pounds.

After

Dry ice blasting removed the foam without damaging the tiles or the engineered timbers. We treated one rafter, reinstated eaves and ridge ventilation and refitted breathable board. The damp smell cleared within a fortnight and the roof covering stayed in place.

Barn Conversion Insurer Condition Report

Before

A barn conversion near Tawstock had thick closed cell foam across the whole roof underside. The insurer requested a condition report before renewing the policy, and the owner was worried the historic timbers had already suffered rot underneath.

After

A five-day removal using dry ice blasting cleared the foam from every rafter and purlin. Thermal imaging and moisture readings confirmed the timbers were sound, ventilation was reinstated, and the insurer renewed the policy without exclusion.

Problems we solve

Problems Our Roof Spray Foam Removal Solves

Foam in a roof is rarely a neutral addition. It changes how the roof breathes, what it hides and what a lender is willing to do with the property. These are the four problems we deal with most often in Barnstaple.

Ask a pro →
01

Mortgage refused because of spray foam

We remove the foam, restore ventilation and issue a removal certificate with photographic evidence and moisture readings. Lenders and valuers accept this pack, and most Barnstaple sales complete within three weeks of the work finishing.

↗
02

Roof timber rot hidden under foam

We cut the foam back, inspect every timber with a moisture meter and thermal imaging camera, treat early rot and replace anything that has gone soft. Catching it at this stage usually saves the rafter rather than the whole roof structure.

↗
03

Condensation and damp patches on ceilings

Removing the foam and reinstating the eaves and ridge ventilation path solves the root cause rather than the symptom. We confirm airflow is restored before we leave and check moisture readings on every rafter.

↗
04

Insulation performance loss

We strip the failed foam and refit breathable insulation, usually mineral wool or breathable board, specified to bring the roof back towards the 0.16 W/m2K target for a refurbishment. You get a warmer loft and a roof that performs as designed.

Yes. We remove open cell and closed cell spray foam from pitched roofs, lofts and attics across Barnstaple and North Devon, and in most cases we do not need to strip the roof covering. We cut the foam out from inside, clean the timbers, restore ventilation and issue a removal certificate. Surveys are usually booked within 48 hours.

It fixes the leaks caused by trapped moisture and blocked ventilation, which is the most common problem we find. Foam that has bridged the eaves gap forces condensation into the rafters, and that shows up as damp patches on ceilings. If the leak is from failed flashing or cracked slates, we tell you at survey and quote that separately.
