Slate roofs are considered the best type of roof as they last the longest compared to other types of roofing materials. Some slates have been proven to last up to 200 years.  Although slate roofs are more expense they are worth the extra cost as they require the least amount of maintenance. We advise to replace broken slates as soon as possible to ensure the roofs longevity.
Slates have a natural ability to be fire and mold resistant. They have a low water absorption so they are resistant to frost damage.. We aim to advise on the type of slate to suit the roof and your budget.
