Initial cost is only one of the costs you should consider when buying a roof for your home. In truth, initial cost is not even the most important cost. For example, you should consider how your roof will contribute to your HVAC costs, how much you stand to spend on repair and replacement costs, and how your roof will protect your home from weather damage. If you are looking for a roof that will help you to save money down the road, you should buy a metal roof instead of asphalt shingles.
Asphalt shingles absorb heat from the sun. In fact, an asphalt shingle roof can easily reach temperatures of up to 150 degrees. This would be acceptable if that heat stayed on the outside of your home. The problem is that shingles will radiate some of the heat they absorb into your home, which can make your AC unit have to work harder to cool your home. A metal roof will reflect some of the sun's rays away from your home. If treated with an emissive coating, a metal roof will radiate what heat it does absorb away from your home. Thus, a metal roof can help you to save up to 25% on your cooling costs.
Asphalt shingles will only last for around 20 years. Thus, while asphalt shingles will cost less initially than metal roofing, you should also budget for replacement costs down the road. In contrast, a metal roof can last for up to 80 years. This means that you can virtually eliminate the need to replace your roof while you live in your home. Another way to look at replacement costs is that you will have to replace an asphalt-shingle roof up to four times before you have to replace your metal roof even once.
Asphalt shingles have a surface like sandpaper. In fact, the protective granules that make up the top layer of a shingle create enough friction with snow that they can prevent the snow from sliding off of your roof. Thus, if you live in an area that gets a lot of snow, you have to worry that the weight of snow building up on your roof may actually cause your roof to collapse. In contrast, a metal roof has a low-friction surface that will allow snow to slide right off of your roof.
Choosing a roofing material for your home should be about more than what you stand to save initially. If you choose a metal roof instead of asphalt shingles for your home, you will pay more initially, but your roof will protect you from higher costs down the road.
