This is not an exhaustive list, however, it will cover most roof defects I have come across over 10 years of roof inspecting. Some roofing systems last longer than others so this is a guide based on slate roofs which typically have a 40-year lifespan.
Metal roofing has a 30-year lifespan and roof repairs are usually cheaper so roof inspections in metal roofing are less frequent. For more details visit us - https://bit.ly/2ZmKWou
