WHEN TO REPLACE YOUR ROOF
The lifespan of a roof, which largely depends on the material type, is normally within a range of 10 – 50 years. It is time to replace your roof when the shingles start to curl or show signs of aging. Roof sags indicate that there is a problem with your roof structure. Mold or moss infestation could also weaken the roof structure. Most importantly, a new roof replacement is needed after an inspection has revealed that the damage has gone beyond repair.
