Is this worth it you may ask? How much can you really save with a cool roof? Well, some cool roof reflecting materials are known to reduce a roofs temperature by a much as 100 degrees. There is also the potential to benefit from utility rebates by installing a cool roof. When we see facts like this, it’s easy to see that significant savings could be made with indoor cooling costs.
Another benefit is that a cool roof will help to prevent air conditioning units from becoming overloaded which can happen when temperatures are especially high. In cities and large towns, this often leads to blackouts or brownouts because buildings retain too much heat for air cooling systems to cope with. Cool roofs help in reducing the amount of heat those buildings absorb, lowering electrical demand.
Before you decide whether a cool roof is right for you make sure you look at any possible disadvantages that may come from this type of roof.
