Asphalt Roof vs Slate Roof

If you are considering installing an asphalt roof or a slate roof, there are many things that you need to research. Both options can provide you with a quality roofing material. However, depending on your current situation, one might suit your needs better than the other. The following are items you should consider before selecting your roofing system.


One of the biggest differences between these two types of roofing materials is the cost. Asphalt is one of the least expensive roofing materials while slate is typically one of the most expensive. Slate tends to be used on high-end homes as it is more attractive than asphalt. You might expect to pay as much as 20 times the cost of an asphalt roof for a slate roof. 

Even though the initial cost of a slate roof is more expensive, it will be cheaper when you consider the lifespan of the material. Some slate roofs can last as long as 175 years. On the other hand, asphalt roofs have a shorter lifespan of 20 years at the most. This means that you will have to replace the asphalt roof several times before you replace the slate one.


Another big difference between these two types of roofing materials is in the installation process. An asphalt roof is much easier to install than a slate roof. With a good roofing crew, you could potentially have a new asphalt roof installed in one day. In some cases, it might take a weekend to finish the project. It will take a longer to install a slate roof and you have to find a crew  that is skilled in installing this type of system as it is a more difficult process. 


These two types of materials differ greatly in how much they weigh. Asphalt shingles are very light compared to slate roofing tiles. if you plan on installing a slate roof, you need to make sure that the frame of the house can support the weight or the material. Otherwise, you could run into serious problems where the roof actually collapses under the weight. In other cases, the roof will flex and cause the slate tiles to crack. This weight factor also contributes to the difficult installation of a slate tile roof.


Typically, slate is regarded as the better looking of the two options. The looks that a slate roof can provide helps contribute to the high cost of its installation. Because it is so attractive, high-end homeowners are willing to pay a little more for this type of roof.

Asphalt shingles can come in a variety of colors and sizes but ultimately the roof will still look like an asphalt roof. If you like the look that asphalt shingles provide, you can definitely save some money by selecting them for your home. However, many people prefer the look of slate and this requires a much larger investment.
