Happy new year – a bit late, but we have been busy.
What a start to the year.
Tilehurst Roofing have processed well over 450 enquiries so far this year 63 on christmas eve alone. Most of the calls were related to storm damage repairs, high winds, continuous driving rain and blown off tiles and slates.
Our roofing teams including the office team have been working 7 days a week and long hours to cope with the high demand.
Besides the most common enquiry, tiles/slates blown off, we have had approx 45% of all relating to damp and condensation.
I have written many times about condensation, and have compiled a quick list of helpful hints.
The damp problem is less easier to explain- but here goes.
The outer layer of brickwork construction can let in rain. Since approximately 1930, house construction changed from predominantly solid wall structures to cavity walls.
Solid walls by the nature of masonry would allow moisture to eventually percolate through, and cause dampness.
This is more evident when the wall or chimney stack is exposed to prolonged and severe wind driven rain.
Brick types vary considerably in their physical properties depending on the type of clay used and method of manufacture. Older bricks will be more porous than the modern day equivalents.
During long periods of wind driven rainfall the brickwork becomes saturated directing excess water down the outer face. Mortar being more porous than the masonry unit, will absorb large volumes of water, which then penetrates the wall/chimney inner face allowing water to pass into the roof space.
Older chimney stacks contain no damp proof course.
Other contributing factors can speed up the ingress of water through this area.
Thats another story!!
Back to condensation….
Did you know the average person sweats and loses around 8 pints of water in a 12 hour period.
