Other factors that can affect a roof's lifespan
Color: Darker colors absorb more heat so they last less
Slope: A roof with a high pitch can last longer because snow and rain can not settle on the roof
Orientation: Roof materials on slopes that face the sun more hours during a day, can have a shorter lifespan
Ventilation: A well ventilated roof increases the lifespan of the covering materials by reducing heat and by not letting mould mildew and wood rot appear
