What Facts You Need To Know When It's Time To Replace Your Asphalt Roof


If it's time to replace your asphalt shingle roof, you're probably considering replacing it with more asphalt shingles. They are the most common roofing material, but if you're going to replace your asphalt roof, check out these six facts. They'll help teach you a little about asphalt shingles, so you get the perfect roof for your home.

An Overlay May Be Possible

An overlay allows you to save a little money by simply placing new shingles over the old shingles. The total savings end up equaling about 25 percent, but many roofing specialists feel the savings aren't worth it. When you do an overlay, you can't check the underlying roof structure for unseen damage, so you may be covering up a bigger problem that will lead to more problems and repairs. Plus, the overlay shingles never last as long as a fresh layer of shingles, so you'll need to replace it sooner. An overlay is only a good option if you are certain there is no underlying damage, it's the first overlay, and you just can't afford that additional 25 percent.

Asphalt Shingles Are Cheap

Luckily, even if you choose to completely redo your shingles, asphalt shingles are one of the cheapest options available, which is one of the reasons they are so popular. They cost about $50 per roofing square or 100 square feet. Metal roofs, which are becoming more popular, costs closer to $100 to $260 per roofing square. On the downside, the cheaper the material, the shorter it's lifespan. While the more expensive metal roofs can last 40 years or more, asphalt roofs only last about 15 to 20 years. So, you may end up saving money on installation, but you'll need to replace it more often, leading to higher lifetime costs.

The Color Can Insulate Your House

When it comes to asphalt shingles, there are tons of style options, such as architectural shingles, which give your roof a bit of dimension to create a unique style. However, the most important option to consider is the color because it plays a bigger role than just how your roof looks. Darker shingles absorb heat, which pulls heat inside your home, making them great for colder climates. Lighter shingles reflect the sun's heat, keeping your house cooler, so they are perfect for hotter climates.

They Are Perfect for Every Roof

Some roofing materials are just out of the question for certain roofs. For example, slate tile is not an option if you have a roof with a low slope because people are more likely to walk on the roof and damage the tiles. Slate tiles are also extremely heavy, making them a bad option unless you install additional support. Asphalt shingles, however are perfect for just about every roof. They withstand wear and tear well, so whether you have a high slope or low slope, they're perfect. Plus, they are light, so you don't need any extra support systems to keep your roof from collapsing.

Options Include Organic and Fiberglass

Asphalt shingles come in organic and fiberglass. Organic asphalt shingles are comprised of a paper base. This base is covered in asphalt and and ceramic granules. Fiberglass asphalt shingles are comprised of a glass fiber base. The base is then covered in asphalt. Because they use less asphalt than organic shingles, fiberglass shingles are better for the environment. They also withstand fire better. However, organic shingles are better equipped to withstand damage from weather and wear and tear. 

Extreme Conditions Cause Damage

If you live in an area that sees extreme heat, asphalt shingles may not be a good option. The heat is known to cause cracks in the shingles, drastically shortening their lifespan. It's also not a good idea to expose asphalt shingles to widely varying temperatures. For example, if your area sees bitterly cold winters and then abnormally hot summers, the asphalt shingles expand and contract. Like bending a piece of metal back and forth, this eventually causes them to break.

Asphalt shingles are good for most homes, but they aren't great for all climates. If your old roof needs to be replaced, contact a roofer today. Get additional reading to find out how much an asphalt roof will cost you.

metal or shingled roofing - what do you choose?

I spent weeks researching metal and shingle roofing to try to figure out what would be the best material to use on my home. I weighed the costs, the length of life, the amount of maintenance required and how well each type would hold up to high winds and strong storms. After compiling all of the information that I needed to make an educated decision about the roofing for my home, I created a blog. This blog is meant to help other homeowners decide which roofing material would be best for their homes now and many years into the future.
