A lot goes into roofing than most people realize. There are fundamentals to technology that come into play here and it’s a good idea to get the nuts and bolts of what they are.
First of all, the reflectivity of the roof is primary. This means that sunlight and heat are reflected away from the structure with a highly reflective color and material. It’s a combination of the two that achieves this and can be the difference between night and day regarding keeping heat away from the building.
The technical name for this is SRI which stands for Solar Reflectance Index. This is a benchmark by how we measure the heat from the sun. Again, a combination of factors such as roof color and material. In addition the next parameter is called emissivity also known as thermal emittance. This is how we measure how much heat the roof absorbs. Top of the list of materials via this index are asphalt and metal which can absorb upwards of 80% or more.
This all piles up under what Floridians need. It’s sunny year round and of late the heat has been abominable. Lifelong residents will testify that the last two summers have been the hottest ever and that may or may not be due to climate change but nonetheless, it is a reality and such heat can raise the prices of energy considerably. People are barely able to make ends meet due to the amount of air conditioning needed night and day to just survive.
In Florida, air conditioning isn’t a luxury, it’s a matter of survival. There’s no telling how disastrous things could get should power go out for millions as it would only take a few days to kill. Your home is your biggest investment and you want it as well protected as possible and the roof is where you start. As mentioned earlier, reflective surfaces is the first line of defense. A good insulated roof that reflects a great deal of sunlight can do wonders regarding cooling the home or business structure. This allows for less use of electricity for running the structure which leads to savings but not compromising safety.
Tomorrow is too late to let your roof fall into disrepair or to not make it heat resistant.
