Spray Foam Insulation

⚠️ Spray Foam Insulation Can Destroy Your Home’s Value

Mortgage denied. Sale blocked. Roof compromised.

Spray Foam Insulation (SPF) was once sold as a “miracle product.”
Now? It’s a property owner’s worst nightmare.

If your loft contains spray foam, you could face serious consequences when trying to sell, remortgage, or release equity.

🛑 Lenders Are Saying “No”

Most banks and mortgage providers across the UK refuse to lend on homes with spray foam in the loft. That means:

  • ❌ You may not be able to sell your home
  • ❌ You may be refused a remortgage
  • ❌ You may not be able to release equity
  • ❌ You could be forced to rip out the foam or replace the roof entirely

❌ Why Spray Foam Is a Serious Risk

🔒 Covers roof timbers – hides damage, preventing proper inspection
🌫️ Stops ventilation – traps moisture, causing mould, damp, and timber rot
📉 Kills property value – homes with SPF can lose £10,000–£30,000+
💀 Destroys roofs – entire roofs have failed due to SPF, especially in older buildings

🏠 Period Properties & Older Homes: DO NOT Use Spray Foam

If you own a listed building, heritage home, thatched cottage, or a property in a conservation area, spray foam can cause catastrophic damage.

Older roof structures must breathe. Spray foam blocks that airflow, leading to condensation, hidden rot, and eventual structural failure.

Once it’s in, the damage is hard to undo  and often expensive.

💬 Some Good Advice from Just Lofts & Build

We’ve been in the building game for over 30 years, and in that time, we’ve seen every insulation fad, gimmick, and dodgy sales pitch come and go.

Here’s the truth:

Spray foam isn’t evil  it’s just being used in all the wrong places.

✅ Want to soundproof a stud wall? Fair enough.
✅ Got a cold underfloor void? Fine spray away.
🚫 Want to slap it all over your roof timbers?
Absolutely not.

Your loft isn’t a spaceship  it needs to breathe.
Cover it in foam and you’re asking for rot, trapped moisture, surveyor nightmares, and mortgage rejection faster than you can say “chain collapsed.”

We’re not here to scare you. We’re here to tell it like it is  and fix it if it needs fixing.
