7 Myths and Misconceptions That Surround Asphalt Roofs

Apr 15, 2020Roofing

When you’re having a roofer replace your roofing system, you have a wide range of options to consider when it comes to materials. In fact, you can choose between materials, such as metal, wood, clay tile or asphalt. While all of these materials can easily suit your home’s needs, the most popular of the four remains to be asphalt. However, despite the material’s popularity, it’s still surrounded by a few myths and misconceptions, such as:

  1. Asphalt Roofs Are Completely Made of Asphalt
  2. One of the common myths that surround asphalt roofing systems is that they’re completely made of asphalt. While it may sound hard to believe, asphalt roofs aren’t actually completely composed of just asphalt. In fact, on average, only 20% of the product weight is asphalt, and lighter weight shingles may even contain less asphalt than that. This is because there’s an industry standard that prescribes a certain minimum weight of asphalt on a roof.

  3. Asphalt Roofs Were Made With Asbestos
  4. Admittedly, this myth is actually partially correct as asphalt roofs before the 1960s really did contain asbestos to keep up with fire safety codes that dictated the materials that can be used for a home’s exterior. However, this is no longer a concern as, by the 1960s, asbestos was phased out as an asphalt roof ingredient after safer and inert mineral stabilizers were discovered and used in asphalt roofs.

  5. It’s Impossible to Repair or Replace a Sealed Roof
  6. Another prevalent asphalt roofing myth is that, once your roof is sealed, it’ll be impossible to repair or replace the roofing system in the future. In actuality, while asphalt shingles often come with sealants that usually do a good job of binding the shingles to one another, you can still separate them carefully with a flat bar, especially when the weather is cooler. However, this is still a delicate practice that may damage your roof if done incorrectly, so it’s still highly recommended that you enlist the services of a roofing contractor to get the job done in your stead.

  7. Hand-Nailing Is Better
  8. Another myth that you’ll often hear about asphalt roofs is that you should hand nail your shingles instead of using a nail gun. This is due to the belief that using a nail gun can result in crooked shingle installation, reducing your roof’s wind resistance by a significant amount. In reality, you can use either methods to install your shingles as long as the contractor makes sure that the nails are installed in the right location.

  9. Cooling Costs of Darker Colored Roofs Are Higher
  10. You’ve likely heard it so many times from other roofers before: if you live in an area with a warm climate, you should avoid darker colored roofs as they can drive up your home’s cooling costs. Surprisingly enough, this is actually a mere misconception. While it’s true that darker colored roofs can become warmer than lighter colored ones, this doesn’t necessarily mean your home’s cooling costs will skyrocket. This is because whether your cooling costs stay the same or shoot up actually depends on how well-ventilated and how well-insulated your home is.

  11. New Roof Shingles Seal Immediately
  12. Unfortunately, new roof shingles don’t seal immediately like some would have you believe. According to expert roofers, newly installed shingles need to receive sufficient solar warmth first before the sealant is activated. Apart from that, how long your sealant activates also depends on a few factors, such as your home’s location, the direction of your roof, the roof slope and the conditions of your area’s climate. This means that there’s no real way to tell when exactly your newly installed shingles will be sealed.

  13. Granules in Your Downspouts Are a Concern
  14. Another myth that surrounds asphalt roofs is that if you see granules in your downspouts, you should be concerned immediately. However, this actually depends on the age of your roof; if your roof is new, and you see asphalt granules in your downspouts, there’s no need to fret as these are just extra granules that have become loose. If your roof is a few decades old, on the other hand, then you may be concerned as granule loss on a decades old roof is a sign that your roof is approaching the end of its lifespan.
