Our view

Foam on a roof is a question, not always a verdict.

We record what is there and what state the timbers are in, then tell you whether it can stay, part of it should come off, or all of it. Removal only when the evidence calls for it.

✓ What that buys

Everything below is included. There is nothing else to pay.

  • An inspection of the whole roof space, wherever it can be reached
  • Foam type, thickness and coverage recorded, with moisture readings on visible timber
  • A written report with photos and locations, ready for a lender, buyer or solicitor
  • A clear condition rating for what we could see. The report is yours to keep
  • A straight answer on what, if anything, actually needs to come off

— What you never get

Not on the day, not on the invoice, not afterwards.

  • A call-out fee or a charge for the report
  • A price that moves once we have seen the loft
  • A removal quote you did not ask for
  • Any obligation to use us for the removal
  • A report we hold back or make you chase

The report records what we could see and what we could not, so nobody is guessing later. Take it to any contractor you like.

Leigh's housing

Wigan roofs were built to breathe.

Leigh is a Greater Manchester town within Wigan borough, with Victorian terraces around the old mill area and later suburbs beyond. Many landlords and owner-occupiers here have roofs that were foamed years ago by firms that no longer trade. We record the foam and the condition of the roof so decisions rest on evidence.

Slates, battens, rafters and felt. An assessment shows what the foam is doing to them.

Also covering the rest of Wigan — same price, same service.

Questions we get asked

The firm that foamed our Leigh roof has gone. Who checks it?
We can. The assessment records what was applied and the state of the roof timbers, whoever fitted it.
Why is spray foam under a roof a problem?
Spray foam is applied to the underside of the roof covering. It bonds to tiles, slates, felt and timber, which can hide damp and decay and makes repairs difficult. Many lenders and surveyors treat it with caution, especially where it covers the roof timbers.
Will it stop me selling or getting a mortgage?
It can. Some lenders decline or ask for evidence, and buyers' surveyors often flag it. A written assessment of what is there and what condition it is in is usually what they ask for. What a particular lender will accept varies, so check with your broker.
What does an assessment involve?
An inspector goes into the roof space, records the foam type, thickness and coverage, takes moisture readings on visible timber, photographs what can be seen and notes what cannot be checked. You get a written report afterwards.
How long does it take?
Around one to two hours in a typical Wigan loft. The report reaches you within 24 hours.
Do I have to remove it?
Not automatically. Whether foam can stay depends on its type, how it was fitted, what state the timbers are in and what your lender or buyer will accept. We give you the evidence to decide.
Can you tell if the timbers are damaged?
Where timbers can be seen or reached we take moisture readings and record staining, softness and mould. Timber fully covered by foam cannot be checked without removing some of it, and the report says so.
What is the difference between open-cell and closed-cell foam?
Open-cell foam is soft and spongy and lets moisture pass through. Closed-cell foam is dense and sets hard. Both are used in roofs, and the type affects how it can be removed and how risky it is.

Know what is under the foam before your buyer does.

£195 fixed. Written report. Yours to keep.
