Asphalt Vs Concrete Roofs
If your roof is getting old and you need reroofing or if you are looking to build a roof for a brand new home, you will need to find a material that fits your needs. Materials can vary dramatically in price, lifespan, appearance, and even weight, each of which can be hugely important. Therefore, it is very important that you understand the differences between each material before you make a commitment. To help you out with that, here is a comparison of two of the most popular roofing materials: asphalt and concrete.
What is asphalt roofing?
First off, you have asphalt, which is a relatively lightweight and inexpensive roofing material that is incredibly common. Many suburban neighborhoods are filled with asphalt roofs, so your home certainly wouldn't look out of place if you were to go this route.
One of the drawbacks of asphalt is that it doesn't protect against heat very well. This ultimately means that an asphalt roof won't be quite as effective at stopping a fire, but asphalt is also more conductive than other options. As such, an asphalt roof won't offer perfect insulation and will allow heat to enter and escape your home. The exact amount of heat will depend on your climate and the insulation in the rest of your home, so proper planning can almost completely mitigate this drawback.
With asphalt, you also need to worry about wind damage. Though individual shingles can resist damage fairly easily, you do need to be concerned about individual shingles being lifted and displaced by wind. Of course, this is only a serious concern in areas with extremely strong winds.
What is concrete roofing?
On the other hand, you have concrete, which looks very similar to asphalt. However, there are some pretty massive differences if you look past the surface.
For example, concrete is going to be more expensive and last a lot longer than asphalt. While asphalt costs $50 per square and lasts about 20-30 years, concrete costs upwards of $150 per square and lasts upwards of 100 years. Comparing these numbers may seem very simple, but there are some other factors to consider as well. While asphalt might cost the same as concrete, over the course of 100+ years, you will also need to worry about those extra replacement cycles with asphalt. With concrete, you will have no such worries as long as you maintain your roof properly.
Concrete is also very resistant to fire and heat, which covers a weakness of asphalt. You won't need to worry about a fire damaging your roof, and insulating your home will be a little easier. Concrete also tends to be a bit more resistant to wind damage than asphalt.
