Does a slate roof add value?

Natural roofing slates not only add value to your home, they also offer something in return. Slate roofing is naturally fire resistant and offers high wind resistance. Most slate roofs can last for up to one hundred years or longer with regular maintenance. Even after being broken, the overlapping slates on a slate roof make it harder for water damage to leak into the structure of a house and cause rot in the walls and ceiling – unlike other materials like asphalt or metal that are less protective against water damage.

Slate roofs are attractive roofs that have a bit of an old-fashioned look and feel. They make a home stand out from others in the neighbourhood without being too ostentatious or flashy. They are definitely worth considering as they’ll also bring increased resale value down the line when looking for properties for sale in your area.

How Are Roofing Slates Fixed?

Roofing slates are typically fixed to the roof with screws or nails that penetrate into the roof deck beneath. They are nailed in place with either galvanised metal nail heads which look similar to most other types of nails or alternatively by using what is called a “blind nail” which screws down the outside so it cannot be seen.

Blind nails have quite drastic advantages, principally because they are much less likely to create leaks around them when installed correctly. This is because rain water will never form under a slate once it has been screwed down properly since rainwater can’t get under it.

The answers to the questions mentioned above should help you decide on whether or not to have roofing slate installed in your property. For further information on our range of slate products please call us on 01200 427711 or email any enquiries to
