We recently started our next project which is the strip and recover of this slate roof on a new build property.
You might be wondering why we are stripping a roof that is less than 5 years old and it all started when the customer has some slates blow off in high winds and found 30mm aluminium nails on the ground. This led him to research the British Standards and he soon realised that the roof that was on his house wasn’t carried to the specification or the standards it was meant to be. Below is a list of things that were wrong.
❌ membrane exposed at the eaves
❌ laps of membrane not taped
❌ wrong gauge batten fixings
❌ counterfeit battens used
❌ slates not graded
❌ slates not T1/S1 as specified
❌ incorrect type, length & gauge slate fixings
❌ ridge batten bracket not installed for DRS
❌ leadwork not carried out to LSTA guidelines
As well as these issues the workmanship was of very poor quality with several problem occurring with the roof soon after they moved in.
We will be carrying out the new roof to full British Standards which as an NRFC Competent Person Scheme member we do on each one of our projects.
The new slate to be used will be the cupa.pizarras R12 excellence 500 x 250 slates which having used several times we can rely on their high quality and excellent performance.
