Slate Roof Pros and Cons

Knowing the typical cost of a slate roof installation in Los Angeles doesn’t necessarily give the full picture when trying to decide if slate is the right roofing system for your home.  Weighing the pros and cons can help you determine if slate is right for you.

Pros of Slate Roofs

Long Life Expectancy

A properly installed and flashed slate roof and last, quite literally, a lifetime or more.  Well maintained slate roofs last around 75 years on average with some still holding strong at around 200 years old!  A new slate roof could very well be the last roof you’ll ever need.

Curb Appeal and Value

There’s no doubt that a slate roof adds both curb appeal and massive value to your home.  These roofs are elegant and timeless and offer a striking beauty that just can’t be replicated.

Fire Resistance

Slate roofs are one of the most fire resistant roofs on the market.  The slate itself is 100% fire resistant.  This makes it an excellent choice for areas where airborne sparks might fly like those that are plagued by wildfires.

Eco Friendly

Because of their longevity, slate roofs are one of the most eco friendly roofs available.  Around 5% of waste that is put into landfills every year comes from roofing waste.  The vast majority of this comes from materials like asphalt shingles which only have a 20-30 year life expectancy.  With a life expectancy that can reach into the hundreds of years, it’s clear how slate can be a benefit to the environment.

Low Maintenance

Once installed slate roofs require little maintenance aside from making sure nobody walks on them.  They will need to be regularly cleaned and this should be done by a professional to avoid damage.

Cons of Slate Roofs


There’s no getting around it: slate roofs are expensive.  As the most expensive roofing system on the market the sticker shock that comes with a slate roof can be, well, shocking.


You might be asking how a roof that’s supposedly so durable with such a long lifespan could possibly be fragile.  The slate tiles themselves are actually very easily broken.  This is why it’s important to only have your slate roof installed by someone who knows what they’re doing.  This is also why it’s important to make sure nobody is walking on the roof unless they’re familiar with how to navigate a slate roof without damaging it.  That means that if you have a slate roof and need work done on another part of the home, like your AC, you’ll need to make sure your technician knows what they’re doing.


Not just any home can have a slate roof installed on it.  The structure needs to be built to hold the extremely heavy weight of the tiles.  If not built for that purpose, the building will have to be retrofitted.
