Professional spray foam removal across the South East

At Alliance Roofing & Building, we specialise in professional spray foam removal, restoring your roof to its original condition safely and efficiently. Many homeowners are now facing problems with spray foam insulation, as it can trap moisture, cause structural damage and even hold up mortgage approvals. Our team removes old or incorrectly applied spray foam to protect your roof and maintain its integrity.

Using safe, non-damaging techniques, we carefully extract the insulation while preserving your roof's structure. Once removed, we inspect and assess your roof to make sure it remains secure, breathable and fully compliant with industry standards. We work with homeowners, landlords and property buyers to eliminate spray foam problems and keep the roof structurally sound and mortgage-friendly.

We operate across Buckinghamshire, Hertfordshire, Berkshire, Middlesex, Surrey, Sussex and London, safely removing open-cell and closed-cell spray foam from lofts, pitched roofs and flat roofs, preparing your roof for re-roofing, new insulation or mortgage approval.
