Why Renovate an old roof
Over time the elements, pollution and enviromental factors all take their toll on your roof. With the rapid expansion in post-war house building, reliance on traditional slate declined in favour of cheaper, pre-cast concreate tiles. Often available in vibrant colours architects also favoured them as they complement their bright, modern designs.
Unfortunately pigment and pre-cast technology was not as advance as in today’s tiles and the vibrant colours faded to the now familiar dull gray. In addition, quality varied and some tiles had design life of only 25 years.
Today in extreme cases the tile surface breaks down, becoming porous. This acts like a sponge, retaining water and encouraging the growth of unsightly moss, green mould and lichens. The retained moisture also increases load on the roof trusses and ultimately leaks to the inside walls, showing up as damp patches.
Important Point! many of these roofs have far exceeded their original life
expectancy, underlining that they are basically a durable, reliable material even
if they may look tired.
