Spray foam insulation may have promised energy savings, but for many UK homeowners, it's now causing mortgage delays, timber damage, and serious roofing concerns. In some cases, removing spray foam isn't enough — a partial or full reroof may be needed.
In this guide, we explain:
- When reroofing is necessary after spray foam removal
- What signs to look for in damaged roofs
- How Countrywide Insulation handles the entire process — from safe removal to repair and certification
Why Reroofing Is Sometimes Required
Spray foam insulation bonds directly to roof timbers and felt. Over time, this can:
- Trap moisture
- Conceal damage
- Prevent inspection of the roof structure
Once the insulation is removed, some roofs reveal:
- Rotten battens or rafters
- Damp, swollen, or split timbers
- Perished underfelt or sagging roof decks
In these situations, simply removing the spray foam isn't enough. Surveyors or mortgage lenders may still flag the roof as defective unless it is properly repaired or replaced.
What the Official Guidance Says
The UK Government's Moisture Risk of Spray Foam Insulation report outlines the potential for serious issues where ventilation and vapour control have been compromised.
Several local authorities, including Croydon Council, recommend full roof inspection and documentation when spray foam is removed, especially in mortgage or sales situations.
How to Know if You'll Need a Reroof
Here are common signs that reroofing may be required after removal:
1. Excess Moisture or Rot in TimbersDuring our removal work, we conduct moisture testing. If readings are consistently high or timber shows signs of decay, full replacement may be necessary.
2. Delaminated Roof Felt or SheathingSpray foam often adheres tightly to roofing felt or boards. During removal, this material can tear or delaminate, leaving the roof vulnerable to leaks.
3. Previous Roofing Defects Now ExposedSpray foam often hides roof issues that were never properly addressed. Once removed, we sometimes discover cracked tiles, sagging sections, or poorly installed structural elements.

Reroofing Options After Spray Foam
If a new roof is needed, we'll walk you through your options:
Full Reroof
Best for older properties or roofs with significant damage. Includes new felt, battens, tiles/slates, and ventilation upgrades.
Partial Reroof
If damage is confined to a section of the loft or rear slope, we can often replace only what's necessary, saving you cost and disruption.
Roof Ventilation Upgrades
In some cases, we can retain the existing roof structure and improve airflow by adding ridge vents, soffit ventilation, or breathable membranes.
Every reroof we complete comes with written guarantees and photographic evidence, suitable for surveyors and buyers.
Do All Homes Need a Reroof After Spray Foam?
No — and that's why our free inspection matters. Many homes we attend do not need a reroof at all, only minor repairs. We always aim to preserve the existing structure where it's safe to do so.
But when damage is found, acting early with a qualified team avoids repeat costs, delays, or failed surveys.
FAQs
Do mortgage lenders require a new roof after spray foam removal?
Not always — but they do require the roof to be in sound condition. If rot, moisture or damage is detected, a reroof may be required.
Can Countrywide Insulation complete the reroof and certification?
Yes. We handle removal, inspection, repair, and certification — all in-house.
Is reroofing covered under insurance?
Possibly, depending on your policy and whether the damage was hidden or the result of previous installer error. We can provide detailed reports for insurance purposes.
