Slate Roofs as the Preferred Option – The Advantages and Cost-Wise Factors

Your roof can be covered with a plethora of roofing substances with the common ones in the U.S. being composition shingles, hardwood shakes (especially cedar), tiled roofs, cement roofs and slates. The choice of substances may depend much on the thickness of your wallet, the condition of the home including the roof, the codes of building, the skill level of roofers you are going to hire and many other relevant factors.

Slates are firm and hard, and their natural form is mined throughout U.S., Spain and U.K. A majority of American slates are mined locally, although there are always the imported versions you can order if you want. The imported ones tend to display different tones of color. Slates are created out of the earth’s compression and located nearby the base of the earth and found in between the sedimentary layers. The compression forces the layers to form a parallel line. Weak points mimicking a laminate structure are also created.

When the slates have been taken out, they undergo the splitting process where thick chunks of them are cut down into thinner pieces. This procedure requires someone with skills but this also means that slate cutting is rather a laborious job; thus, requiring higher costs of production.

Slates are high in price as their production involves a lot of laborious work. The rise in cost is also due to the need of hiring highly-skilled roofers who know in extent the ins and outs of working with slates. At the same time, slates are among the heaviest items used for making roofs. You need to strengthen the frame and structure of your home before you can consider applying slates as your roof. The mentioned reasons tend to increase the cost even more, but in the long run slates are considered among the most cost effective when you take into account their little to zero requirement in terms of maintenance and repair.

Slates may stay strong and firm for at least a full century, whereas asphalt shingles are only capable of maintaining their performance in twenty – thirty years. In short, slates are at least three times more durable than asphalts. From a narrowed perception, when the long-term factors are taken into consideration, slates do acquire higher initial costs than asphalts due to their expensive installation requirements. Nevertheless, when an overall view is taken into consideration, slates provide the cheaper option as they increase the value of your home.

Indeed, slates do not need a lot of maintenance, and this point plays a big role in their cost-wise factor when compared to other roofing substances. For example, slates are unlikely to warp due to their resistance against extremely high and low temperature. At the same time, slates are unaffected by pests and molds due to their sterile nature. Bugs, flora and fauna are not interested in them either.

Last but not least, when analyzing the composition of slates you may find a number of benefits associated to their use. Firstly, they’re comprised of natural substances. Secondly, they’re fire resistant and fireproof. Thirdly, slates are water resistant and water is not able to penetrate into their internal structure.
