Natural, durable roofing
A slate roof is as old as time itself… so it seems. There are two main types of slate roof: hard and soft. They make a hard slate roof from stone that doesn’t absorb water, is moisture resistant, therefore doesn’t become warped. A hard slate roof can have a life expectancy of up to 200 years. The soft slate roof, however, being the weaker of the two, has a life expectancy of up to 125 years. Both hard slate roof and soft slate roofs are fire and weather resistant.
When it comes to slate roof vs composite roof and which is better, both have pros and cons. The composite, aka asphalt, is the most common of the two because they are less expensive, easy to install and come in many colors.
The composite asphalt shingles are lightweight, therefore, will fit any roofing structure, whereas slate roof shingles are heavier and need a more supportive structure. The downsides to composite asphalt shingles, they are not as weather-resistant, high winds can rip them off, and they are prone to algae, fungus, and mold, with a lifespan of 20 to 30 years maximum.

- Professional inspection – a qualified slate roof contractor inspection every five years.
- Keep a logbook – record each time the gutters are cleaned, and inspections or repairs are done.
- Ventilation – make sure the attic has proper and sufficient ventilation to keep moisture out of the attic
- Instruct any contractors to wear soft sole shoes when walking on your slate roof. This would include chimney sweeps and painters, or any contractor that needs access to your roof.
