Covering the basics of roofing
Replacing your home's roofing is one of the most dramatic exterior facelifts you can perform on your house. It is a major home improvement project that can cost thousands of dollars – which is why it's so important to do your research. Each of the various types of roof panels on the market has unique characteristics, which makes some kinds of tiles better than others for certain applications and climates.
An Overview of the Different Types of Roof Shingles
Composite or asphalt roof shingles are a standard in the world of residential roofing. Asphalt roll roofing is very affordable and easy to install. It has a long life and excellent weather resistance, especially when protected with weatherproof roof coatings.
However, there are many other options. Metal roof tiles have an extremely long life expectancy – in many cases, they last as long as the house stands. They do a perfect job of sealing the roof and protecting your home's interior from the elements, and they have a very high level of fire resistance. Because they reflect heat, metal roof tiles also help your home stay cool during the summer.
Clay roof tiles, by contrast, are well-known not for reflecting heat away but for trapping it inside the house. Because they make such excellent insulators, clay roof tiles are a popular choice in colder climates where homeowners face long winters. Closely related to clay tiles are concrete roof tiles, which boast similar heat-trapping properties. With clay and concrete, it is vital that you consider the weight of the tiles, as they're both very heavy. You need to ensure your house is structurally sound enough to bear the extra weight, or you'll be taking a major risk.
Additional Roofing Considerations
While climate, cost and weight are all major considerations, they're not the only things you need to think about when choosing the best roofing for your home. The slope of your roof is a key consideration as well; asphalt shingles are good for roofs with sharp slopes, as the slope allows rainwater to drain off quickly, thus minimizing damage. Snow and rain also glide off steep metal roofs very efficiently.
Attic ventilation is another factor you'll have to keep in mind, particularly if you're considering adding radiant barriers to your home. Asphalt shingles don't offer nearly as much ventilation as metal and clay roof tiles, and giving your roof an extra bit of breathability will heighten the effectiveness of your radiant barrier as well as extend the life of the roof itself.
