Inspection of an exposed coastal property

A very exposed coastal property was inspected by Colin Cockram last week that had a series of mono-pitched roofs. The roof slopes were measured and were found to have a pitch of around 16 degrees. The tiles were also checked and it is estimated that there was a 100mm headlap. The type of tile was seen to be a Marley Eternit single Roman pantile which are designed to go to pitch of no less than 25 degrees with a 100mm headlap. Therefore these roof pitches are far too shallow.

Inspection of an exposed coastal property A common way of overcoming this problem was to lay double felt under the tiles to act as a secondary means of defence against rain penetration. Colin’s internal inspection of the roof voids confirmed that the Hessian reinforced bitumous felt had condensated between the layers causing the bottom layer to rot which has now fallen down within the roof space.

It is likely that the roofs will need to be stripped and recovered with a different type of material such as single membrane system. This will be very expensive easily justifying the cost of having a full Building Survey undertaken.


Having served 16 years in the army Colin re-educated during the early 1990’s including two years at the Camborne School of Mines reading Mineral Surveying and Resource Management achieving a first class Diploma (Dip CSM). This allowed direct entry to the second year at The University of the West of England, Bristol reading Valuation and Estate Management. Training and experience was gained with Exeter City Council Estates Department and Sheperds Chartered Surveyors qualifying as a Member of the Royal Institution of Chartered Surveyors in June 2003. Colin set-up the company in May 2009 and covers the complete range of services.
