Slate roofing is a sophisticated choice for homes, businesses, and industrial structures, as it is one of the world’s most durable roofing materials. Slate roofs, when properly installed, don’t require much maintenance other than timely inspections and minor repairs.

A properly installed and maintained slate roof can survive over 50 to 100 years. But, factors including manufacture, the mineral and physical properties of the material, geographical location, and appropriate installation can all affect the lifespan of a slate roof.

What is a Slate Roof?

A slate roof consists of overlapping slate roof tiles that are securely bonded to a solid substrate or a roof deck. A Slate is one of the few roofing materials that does not require replacement throughout a lifetime. Slate shingles will endure at least 125 years in normal climates, and even up to 200 years in some cases.

Slate is also regarded as one of the most attractive roofing materials. Slate has a natural, timeless beauty that will never go out of style as a stone. Slate shingles go nicely with both classic 19th-century residences and modernist homes developed in recent decades. In addition, when it comes to colour, slate is one of the most versatile roofing materials. Slate tiles come in a variety of colours, including green, red, purple, grey, and black.

Is Pressure Washers good for the slate roof?

Moss growth in driveways can quickly be fixed by a pressure wash, but, can you use pressure washing in slate roofs?

The simple answer is, no. using a pressure washer is not recommended as power washing can break apart slates especially those slates that are nearing the end of their usefulness. Also, slate joints are totally out of reach of pressure washing, this not only risks destroying slate roofs, but it also leaves spores behind. Any pressure higher than that of a garden hose risks harming the slate and/or the sheathing beneath it.

The proper way to clean the slate roofs?

Ordinary homeowners that have very little experience and knowledge with slate roof cleaning and slate roofing material tend to clean their slate roofs by themselves. The result is they end up using the wrong moss killing chemicals such as bleach or ammonia. They might also attempt pressure washing in an attempt to quickly remove the stains but this can result in water driving under slats or breakage.

We advise that instead of doing it by yourself which risks you and your well-being, you can hire a professional roof cleaning company to help you out. These professionals have the proper tools and the right approach on how to clean your slate roof.

Slate Roof Cleaning and Inspections

As a homeowner, you need to regularly check your roof but should be limited to removing organic debris stuck in your roof tiles.
