We'll transform your worn-out roof into a stunning new one!

A full roof installation is one of the biggest investments you'll make in your home — so getting it right matters. At Sage Roofing, we manage complete roof installations from start to finish for homeowners and developers across the Vale of Glamorgan, including Barry, Penarth, Cowbridge, Llantwit Major, Bridgend, Cardiff, Dinas Powys, Rhoose, St Athan, Sully, Wenvoe, Ogmore-by-Sea, Pontyclun, Porthcawl, and beyond.

From stripping the old roof back to the rafters, through to the final ridge tile, we handle every stage with care and professionalism. No shortcuts, no skimping on materials — just a roof that's built to protect your home for decades.

What's Included in a Full Roof Installation

Every full roof installation we carry out begins with a thorough structural assessment. We inspect the rafters, purlins, and roof timbers for any signs of rot, movement, or damage, and address any issues before a single tile goes on. New breathable roofing membrane is laid, quality treated battens are fixed, and your chosen tile or slate is fitted to manufacturer specifications and current building regulations.

We also handle all the detail work — lead flashings around chimneys and abutments, valleys, verges, and ridge details — ensuring your new roof is completely watertight and properly finished in every respect. It's the kind of thorough approach that separates a roof that lasts from one that causes problems for years to come.

New Builds, Extensions & Full Replacements

Whether you're roofing a new build, replacing an ageing roof that's beyond economical repair, or covering a substantial extension, Sage Roofing have the experience and the team to deliver. We work with tiles, slates, and flat roofing systems, meaning we can handle virtually any roof type on any property right across the Vale of Glamorgan.

All of our full roof installations comply with current building regulations, and we provide fully documented guarantees on completion — handy to have on file if you ever come to sell your property.
