“Another company quoted us for spray foam and made it sound like the modern option. Select Roofing explained exactly why they wouldn't touch it and what we should do instead. Genuinely grateful for the honesty.”

Insulation — Formby, L37
Roof & Loft Insulation in Formby
Formby’s mix of Victorian and Edwardian properties near the village, 1930s semis, and modern estates toward Freshfield means insulation needs vary enormously street to street. Many of the older properties still have little or no loft insulation beyond what was fitted decades ago, well below current recommended depths.
We’ve worked on roofs across Formby for over 30 years, and insulation is something we assess as standard during any re-roof or dormer conversion — not just something we bolt on separately.
A quarter of a typical home’s heat is lost through an under-insulated roof — often £250–£400 a year in Merseyside, simply escaping upward. Unlike many insulation-only companies, we assess your insulation as part of a proper roofing survey, and we’ll tell you honestly which materials are worth it — and which, like spray foam, we won’t install at any price.

⚠ A Warning About Spray Foam Insulation
We do not install spray foam insulation, and we’d strongly advise against anyone doing so. It’s currently causing serious problems for UK homeowners — an estimated 250,000+ properties may now be effectively unmortgageable because of it. Read our full guide on why we won’t recommend it →
Common questions
Insulation in Formby — What People Ask
How much insulation does my loft actually need?
Current Building Regs recommend a minimum of 270mm of mineral wool insulation (or the equivalent in other materials) for a typical loft. Many older Merseyside properties have significantly less than this, sometimes as little as 50-100mm from decades ago.
Why won't you install spray foam?
Spray foam can trap moisture against roof timbers, prevent proper ventilation, and make it impossible for surveyors to inspect the roof structure — leading to widespread mortgage and resale problems across the UK. We don't believe it's in your long-term interest, regardless of the upfront cost saving some companies offer.
Do older Formby properties near the village need different insulation to newer estates?
Often, yes. Victorian and Edwardian properties near the village centre commonly have little to no original loft insulation and different roof void shapes to modern estate housing toward Freshfield, which can affect which insulation type and depth is genuinely appropriate.
Are there grants available for insulation?
Some households may qualify for support through schemes like ECO4 or the Great British Insulation Scheme, particularly those on certain benefits. Eligibility rules change, so we'd recommend checking current criteria directly, but we're happy to advise on what we see during a survey.
Will insulation stop condensation in my loft?
Insulation and ventilation work together, not against each other. Poorly installed insulation that blocks airflow can actually worsen condensation. We assess ventilation as part of any insulation job, not just the insulation itself.
