Slate Shingles Compared To Asphalt Shingles

Buying a premium roofing material is not all about looks. If it were, it would be sheer vanity to drop thousands of dollars on a roof when you could buy asphalt shingles and get the same results at a fraction of the cost. However, before you write off premium roofing materials, you need to know that asphalt shingles will not give you the same value as a premium roofing materials such as slate. Although slate comes with a somewhat prohibitive price, it might just make the most sense in the long run. 

The Weaknesses of Asphalt Shingles

The primary component in asphalt shingles is—no surprise—asphalt tar. While tar is cheap and waterproof, it is susceptible to damage from hail and the sun. UV rays can dry out the volatiles in your shingles, at which point they become brittle and start to crack. To prevent his from happening, shingle manufactures will coat the tar with a layer of protective granules. Hail can easily scrape of the these granules and/or punch holes in your shingles. Thus, asphalt shingles are susceptible to weather damage and even in good conditions will only last for around twenty years. Thus, those who buy a shingle roof are only setting themselves up for future repair and replacement costs. 

The Strengths of Slate

Slate is a rock that splits along naturally occurring planes in the rock. Thus, it is easy to break slate into flat tiles. Once in place, slate will resist hail, wind, and sun damage for decades. In fact, a good slate roof can last for two-hundred years. While slate is not indestructible and you might have to deal with a few repairs here and there, a slate roof will be far more durable than asphalt shingles and will last up to ten times longer. What this means is that you should not have to worry about repairing your roof during your lifetime. 

While you can coat asphalt shingles with pulverized slate to increase their strength, it's just more durable when you use it in one huge sheet rather than small granules affixed to an asphalt shingle. While the initial cost of a roof is a concern, you cannot ignore future costs. For those who want to avoid replacements costs, which can creep up at the most inopportune times, buying a slate roof is a better value than buying asphalt shingles.
