When you are choosing material for a new roof there are always cost considerations
. However, you also want to look at the long-term. Though you may pay more up front if the roof is going to last longer than a less expensive material you want to look at that aspect. For instance an asphalt shingle roof is less expensive than a slate roof but it will only last ten to twenty years. In addition asphalt roofs are less likely to succumb to the effects of wind and rain, thus creating the need to make more repairs and invest in replacement shingles. From a cosmetic angle you are very limited in colors and designs of asphalt shingles, so if you want something other than the traditional green slate will provide that for you.
Since slate roofs are more fire and wind resistant than other roofing materials you will spend less money replacing shingles that have suffered weather damage. That doesn't mean it will never be a problem but it will certainly be less problematic than with asphalt which lacks the resistance necessary during high winds and rain. In fact, asphalt shingles often buckle even under the weight of snow, so if you live in an area where you experience a lot of snow you will fare better with a slate roof. It's important to consider all of the long term effects of other materials and look at the money savings slate roofs will provide.
Making the right choice in roofing material is one of the most important factors and you need to look beyond the initial cost factors and analyze the savings you will experience4 over the life of your roof. This factor will provide you with cost savings over the long term and reduce the initial cost.
