Progress with the roof and extension

June 27, 2013 /

We are making good progress this week with both the roof and rebuilding the extension.

While the weather has been good, attention has been turned to rebuilding the extension.  We can’t progress with the pointing until we have had the go ahead from the architect on the choice of materials.  We have completed a test panel for approval using Nosterfield River sand and hydraulic lime, but this needs a little bit of time to dry out so we can see the true colour.

It could a couple of days to completely felt and lathe the roof.  However, today work started on relaying the slates.  Five courses are on at the rear of the house.  Slightly less at the front, due to the rooflights having to be fitted as well.  We have had to buy some additional slates to make up for the ones that were damaged or too aged to be reused.

Concrete blockwork on the inside then 100mm insulation and finally the original gritstone on the outside. Once it is finihsed, we will get it sandblasted to match the main property.

This is the view of the front of the roof with the two rooflights. We are waiting for some lead before the slates can be fitted underneath each of the rooflights.

We had to change the size of the rooflights so that they would sit between the purlins underneath. These are conservation windows from a company called Fakro (did you guess?). They are pine on the inside, but will be painted to match the ceiling colour.

Five courses of slates on the back of the roof and the two re-built chimneys. This is day 3 for putting the roof back on.

Pointing

June 18, 2013 /

The pointing on the property is what is called “Weatherstruck”.  This is where the pointing is very defined and stands proud of the joint.  Apparently, the belief was that the protruding pointing would throw any rainwater clear of the wall.  However, this style of pointing is not seen as acceptable as it looks unsightly and can damage the masonry.  The pointing is made of a sand and cement mortar. This is also frounded upon these days as it doesn’t breath (allowing moisture out) and is too hard (harder than the actual stone that has been pointed).

All of the existing pointing needs to be chipped out before the masonry can be sandblasted.  This is a very tendency job and we have had a couple of men on this job since last week.  It should be finished in the next day or so.  Much to their relief.

Once the masonry has been sandblasted, a test panel of 1 meter square will be completed using Nosterfield sand and hydraulic lime.  This should breathe and will be much more sympathetic to the look of the property.

Before the outside of the house can be sandblasted, all the old pointing has to be removed. This will then be replaced once the sandblasting has been completed.
