“They came out the same day, found the problem straight away and had it fixed before the rain came back. Honest price and very tidy. Highly recommended.”

Conservatory Roof Conversion — Crosby, L23
Conservatory Roof Conversion in Crosby
Crosby's coastal position means roofs here take more punishment from the prevailing westerly wind than properties a few miles inland. A lot of older conservatories are still fitted with the original glass or polycarbonate roof — the kind that make a room unusable for half the year, too hot in summer and too cold in winter. Converting to a solid roof genuinely changes that, but it also changes what's legally required: the Building Regs exemption a glazed conservatory enjoys is broken the moment you go solid.
We arrange full Building Regulations approval as standard on every conversion, targeting the current U-value requirement of around 0.18 W/m²K — a dramatic improvement on the 2.0+ W/m²K typical of an old glass roof. That's the entire reason the room becomes usable again, not just better looking.
We don't offer wrap-over or clad-over roofs, where a new structure is fitted over the old one rather than properly replaced. It's the cheapest method on the market, and the one most likely to cause condensation and leaks once the old and new structures start moving independently. Every conversion we do involves proper removal and replacement.

Building Regulations
Building Regs & U-Values in Crosby
A glass or polycarbonate conservatory is generally exempt from Building Regulations. Convert to a solid roof and that exemption breaks — full approval, covering both structural capacity and thermal performance, is genuinely required. We target the current U-value guidance of around 0.18 W/m²K under Approved Document L, and obtain the completion certificate a buyer's solicitor will ask for when you sell. See our complete guide to conservatory roof conversion for the full detail.
Common questions
Conservatory Roof Conversion — What People Ask
Does my Crosby conservatory need Building Regs approval to go solid?
Yes, in almost every case. Your glazed conservatory is currently exempt; converting to a solid roof breaks that exemption and full approval is required. We arrange this as standard.
Will my Crosby conservatory frame take a solid roof?
Often, yes, but it genuinely needs checking. A structural survey confirms what your existing frame and foundations can support before anything is quoted.
What U-value will my new conservatory roof achieve?
We target around 0.18 W/m²K under current guidance, a dramatic improvement on the 2.0+ W/m²K typical of an old glass or polycarbonate roof.
Do you offer wrap-over conservatory roofs?
No. Wrap-over roofs are fitted over the existing structure rather than properly replacing it, which commonly causes condensation and leaks. We always fully remove and replace.
How long does a conservatory roof conversion take?
A standard conservatory typically takes a few days, depending on size and Building Regs timelines. We give a specific timescale after survey.
