New tiles old tiles how long to age roof.

Adding new roofing over old sometimes called a re roof is possible only with asphalt shingles also called composition shingles. I can t imagine paying to encourage moss and lichen to grow on my roof. My personal home has a tile roof and it went 32 years before needing to be replaced. Got to really ask whos paying the bill in reality new roof tiles should always be used unless other wise agreed generally this would be discussed with the customer at some point prior to getting to roof level whether the wanted new tiles same as the existing tiles or whether they wanted you to try and get old tiles so as to blend in better with the existing building.

It is certainly possible that a tile roof could last 40 years. Manufacturers typically guarantee the tiles for 30 years and suggest that 60 years is a reasonable service life. But can they last longer. Whilst this may make the new and old tiles look the same it can often look patchy due to the lack of quality control during the application which is difficult to achieve in the open air.

Nobody minds at all. It is well known that clay concrete roof tiles and good quality natural slates can have an incredibly long lifespan. Clay and concrete roof tiles have a long history and a good track record. Up their roof for as long as possible using old tiles scavenged from the buildings that have already been reroofed.

So long in fact that the tiles or slates will outlast the other components of the average pitched roof. If the underlayment and flashings deteriorate under a perfectly fine tile roof all of the tiles will need to come down. When concrete tiles absorb water the increased weight can cause strain on the roof structure. Even in the most extreme saturation tests the added weight of water absorbed by concrete tiles is only a maximum of 10 and in real world practice much less at around 5.

Clay tile roofs can last 50 years or longer. Some clients are tempted to ask for the roof to be painted with a pigmented coating to restore the original colour. While clay roof tiles have been used on roofs for centuries concrete tiles have become more widespread over the last half a century. The truth is it really should ve been at more like 27 years.

You can t do it with wood or slate for example and you should never mix materials such as laying asphalt shingles over cedar shakes. The old handmade clay pantiles are a devil to match exactly so most old roofs here have a patchwork of slightly different coloured tiles.
