Spray foam survey checker

Answer a few questions about the foam and the roof you can see from your loft. The result highlights signs worth checking. A surveyor can inspect small areas beneath the foam and take moisture readings to assess the timber.

Could spray foam be hiding roof damage?

Where can you see the foam in the loft?
What do you notice beside the foam?
Are there marks on the visible timber or roof lining?
Have you noticed water near the sprayed roof after rain?
Has any visible darkening beside the foam changed?

Indicative only. What is actually happening is confirmed on site. Request an assessment for the definitive answer.

What the levels point to

Signs point toWhat it means
Few visible signsYour answers show few signs of damage on the areas you can see. Foam may still cover parts of the timber, so a survey can check beneath it if you need to establish the roof's condition.
Signs worth checkingThe visible marks or position of the foam make a closer inspection sensible. A spray foam survey can include moisture readings from the rafters and checks beneath small areas of foam.
Stronger signs of concernSoft timber, spreading marks or visible moisture call for a survey soon. A surveyor can assess the rafters, record moisture readings and report on the roof's condition.
  • A roof leak: Wet marks after rain may come from a fault in the roof covering. A surveyor can check the visible roof and timber alongside the areas covered by foam.
  • Loft condensation: Mould or damp marks on cold roof surfaces can also develop where loft ventilation is poor. Moisture readings help a surveyor assess the affected timber.
