What we offer
Loft boarding is one of the most practical and cost-effective ways to make use of the space above your ceiling. A well-boarded loft adds usable storage without affecting your loft insulation — the key is installing boards at the correct height above the insulation, using a raised boarding system rather than simply laying chipboard on top. CMW Roofing & Renovations installs loft boarding throughout Southampton (SO14–SO19), Eastleigh, Chandler's Ford and across Hampshire.
We also carry out roof repairs, new roof installations and full flat roof replacements — so if you need roofing work alongside your loft boarding, we can combine both in a single visit.
Partial loft boarding
If you only need a section of your loft boarded — for example, a defined storage area along one side — we can board exactly the area you need, leaving the rest undisturbed.
Loft hatch upgrades
We can replace a standard loft hatch with a larger, insulated version that makes access easier and reduces heat loss. A proper hatch makes a significant practical difference when using the loft regularly.
Loft ladders
We supply and fit loft ladders alongside boarding work. A fold-down or sliding loft ladder is safer and more practical than a stepladder, and can be fitted at the same time as boarding.
Loft lighting
Basic LED lighting can be added to a boarded loft at the time of installation. Good lighting makes the difference between a usable storage area and a dark, impractical space.
Survey and advice
If you're unsure what your loft will accommodate, we carry out a free survey covering the available headroom, current insulation depth, access, and what kind of boarding installation would work best for your property.
Frequently asked questions
Does loft boarding damage insulation?
Not if done correctly. The key is using a raised boarding system that lifts the boards above the insulation rather than compressing it. Compressed insulation loses its effectiveness and can cause condensation problems. We always use raised systems that preserve the full insulation depth.
How much does loft boarding cost in Southampton?
Pricing depends on the size of your loft, the boarding area required, and whether a ladder and lighting are included. We provide a free written quote before starting.
Can you board a loft that already has insulation fitted?
Yes. Most of the lofts we board already have insulation — either loose fill or rolls between the joists. We use raised boarding legs to sit the boards above the insulation rather than compressing it.
What boarding system do you use?
We use raised boarding systems with legs that clip to the joists and elevate the boards above the insulation. This maintains the insulation's thermal performance and avoids the issues associated with laying boards directly on top.
Can I use a boarded loft as a habitable room?
No. A standard boarding installation creates usable storage but is not a structural conversion. For a habitable room you would need a full loft conversion with structural work, fire safety provisions and planning permission. We carry out boarding only — we do not carry out loft conversions.
