Spray Foam, Insulation and Roofing Questions

What customers ask us before they ring, answered by Dean and the team.

Spray Foam and Mortgages

Can I sell or remortgage my property if I have spray foam insulation installed?

Often, yes. The government's guidance of 22 October 2026 names Nationwide, Lloyds, Santander, Barclays, NatWest, Coventry Building Society, The Co-operative Bank and HSBC as open to lending on homes with spray foam, subject to their own requirements. Speak to your lender, and see our summary of the guidance.

Will removing spray foam insulation help my property meet mortgage lender requirements?

It can. Our removal and new roof on Acorn Drive was signed off by Building Control and passed by HSBC (see the Belper job). The government says removal won't always guarantee lending, so get a specialist survey and talk to your lender first.

Can closed-cell spray foam be removed without replacing the whole roof?

Sometimes. One homeowner was told by several roofers they needed a new roof at about £20,000. Our survey found the closed-cell foam could be taken off by hand, and we removed it for £8,000. Where the felt behind the foam is non-breathable or failing, a new roof can be the right answer.

Will spray foam removal damage my roof timbers or roofing felt?

It can if it's rushed, so we avoid abrasive ice blasting where it could damage the roof and remove foam by hand where the survey says that's possible. If the felt or timbers turn out to be damaged once the foam is off, we tell you, and as roofers we can repair it.

How long does spray foam removal take?

Usually 2 to 5 working days, depending on the size of the property and the type of spray foam. More on spray foam removal.

Do you provide certificates, photos and documents for mortgage lenders and surveyors?

Yes. We photograph the work throughout, take moisture readings where they are needed and hand over full documentation for you, your surveyor and your mortgage lender.

Loft Insulation and Condensation

How much loft insulation should my property have?

We usually lay 300mm of Knauf or Rockwool: 100mm between the joists and 200mm cross-laid over them, to the Building Regulations that apply. See loft insulation.

Do you remove the existing loft insulation and clean the loft first?

Yes, where the old insulation needs to come out, and we always vacuum and clean the loft floor before the new insulation goes down.

What is the difference between mineral wool loft insulation and SuperFOIL?

Mineral wool is laid thick between and over the loft joists. SuperFOIL, such as SF19 and SF40, is a thinner system fitted under the rafters, and it only performs as specified with the right air gaps and sealed joints. On Victoria Avenue in Borrowash we fitted both.

Why is my loft getting condensation, and will more ventilation fix it?

We often find blocked eaves, poor airflow, insulation that stops the roof breathing, or non-breathable bitumen felt. Vents alone don't always fix it, so we find the cause first. On one house, dry ridge ventilation and lap vents cleared it within 2 to 3 days. See roof ventilation.

Roofs and Surveys

How do I know if my roof needs replacing or just repairing?

A survey will tell you: we say what needs attention and what doesn't, and we don't automatically recommend the expensive option. Ageing materials, damaged tiles and leaks that keep coming back are the usual reasons for a new roof.

Do you do roofing and spray foam surveys?

Yes. Specialist surveys take 1 to 2 hours on site. Call us to arrange a professional survey. Every job is then quoted individually.
