Loft Insulation in Rumney

Rumney's interwar and post-war houses

The 1930s semis here typically have hipped or gable-ended roofs with cut timbers, a central purlin and reasonable headroom in the middle. They were built with no loft insulation at all, so what you find now is whatever was added later, often a thin early layer with a newer roll laid over only part of the loft.

Post-war council-built homes in and around Rumney, many now privately owned, tend to have lower, simpler roofs. Their lofts are smaller but quick to bring up to 270mm.

Spray foam is the issue to watch for. Some older roofs have had polyurethane foam sprayed onto the underside of the tiles or slates, usually sold as a fix for slipping tiles or as an insulation upgrade. It can trap moisture against the timbers, and some lenders and surveyors now flag it when a house is sold or remortgaged.

Spray Foam Removal in Rumney

Where foam has been sprayed onto the roof underside, we strip it, clean the timbers and re-insulate in a way that lets the roof breathe.

Loft Mould Treatment in Rumney

Older roofs whose vents have been covered over can grow mould along the rafters. We treat it and restore the airflow.

Before we start on a Rumney loft

Some homes on the hillier streets have steps up from the pavement, so we carry materials in by hand and protect the route through the house. On busier roads such as Newport Road, we agree where the van will stop when we confirm your booking.

If you've been told your roof has spray foam, our spray foam removal guide explains why it's often taken out and what's involved, and the spray foam removal service page covers how we do it.
