Why Metal Roofs Are Better than Asphalt Roofs

There are many myths surrounding metal roofs.  We have heard that metal roofing systems are noisier, attract lightening, and are much heavier than their asphalt competitors.  All of these statements are simply untrue.  A metal roof may cost a bit more, but it will also come with a 50-year warranty in most cases.  Your asphalt roof shingles may also get you the same warranty, but this doesn’t mean that they are going to last for 50 years and the warranty is very limited.  Metal roofs last 4 times longer than asphalt and are actually much, much lighter.  Even better, they are much more energy efficient and come in a variety of styles and textures.  In fact, metal roofing systems can actually be installed that look just like asphalt!

Asphalt Roofs Fail!

From the Experts:

“When it comes to shingles, the drawbacks center on service life. While asphalt shingles come with warranties ranging from 20 to as long as 45 years, roofers and builders remain skeptical of those warranties. Since warranties are a marketing device, they are not a reliable predictor of lifespan. In the past decade, there have been many complaints of asphalt shingle failure long before warranties expired. Many homeowners have been dissatisfied with warranty payouts that didn’t cover all the costs of repair or replacement as well.”  – Bob Vila

“Failed shingles that we have tested contain approximately 30% asphalt by weight. New shingles contain less than 25%. This asphalt is mixed with sand and fine mineral matter and then has granules embedded in it. There is no separate asphalt binder for the filler. What coating exists on the back of the shingle appears to have bled through the mat from the top side during manufacturing. No wonder shingles “weep” water after only a few years.” – Richard Tippet

“The pressures placed on large, public companies to maintain profitability brought forward good old American ingenuity, reduce fiberglass mat weight (fibers were expensive) and increase filler content (asphalt was also expensive)…” – Dwain Bouton, President

Laboratory Testing Facilities Say:

“Due to the severity of the roof environment, even a one year old roof may look different from a roof that was just installed. While you may have first noticed the cracks or blistering from the ladder as you were cleaning the gutters, please be mindful that these normal weathering characteristics may not be visible when you view your roof from your front lawn or driveway.” – The Lifecycle of Your Roof
