Belmont Roofing Rooflight Installation Norwich

Rooflights

Multi-Discipline Projects

Changing rooflights is the single most common request for our repair services. It is also the area of most potential risk to both our operatives and to anyone working below. Even replacing a single rooflight needs careful planning and risk management.

P.V.C rooflights were often installed as being a cheaper option that G.R.P but in practice may require replacement within 5-10 years. There are various grades and thicknesses in the panels and shortcuts are often taken for commercial advantage. P.V.C tends to suffer from P.V.C “migration” and will dry out and become brittle. The product is prone to movement and the mastic sealants at the tail end of the sheet will distort and fail and allow driving rain to penetrate the building, especially in shallow roof designs.
