Roof Restoration Contractors
Why should you renovate an old roof rather than replace it?
Over time the elements, pollution and environmental factors all take their toll on your roof. With the rapid expansion in Post-war house buildings, reliance on traditional slate declined in favour of cheaper, pre-cast concrete tiles. Often available in vibrant colours architects also favoured them as they complemented their bright, modern designs.
Unfortunately pigment and pre-cast technology was not as advanced as in today’s tiles and the vibrant colours faded the now familiar dull grey. In addition, quality varied and some tiles had a 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 liches. The retained moisture also increases load on the roof trusses and ultimately leaks to the inside walls, showing up as damp patches.
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. In most cases, careful repair of structural defects followed by a application of antifungal roof colouring, this will restore the vibrant colours that were so appealing in the original tiles and re-seal them against the elements. This cost effective solution will save you thousands compared to stripping off old tiles and fitting a new roof.
