4 Common Roofing Mistakes When Replacing Asphalt Shingles

Ever since modern roofing techniques have been introduced, the use of asphalt shingles has been one of the most preferred roofing materials by many homeowners. They are relatively easy to install and can last for at least 20 to 25 years through property maintenance. Although installation is a breeze, some people still commit mistakes when dealing with asphalt shingles. Even the best DIY roofers do make those mistakes from time to time. That’s why it’s always best to call for a professional roofing contractor. Read on to learn more about four of the most common mistakes that are made when using asphalt shingles for roofing.


Reusing Old Flashing


Recycling old flashings sounds like a wise decision at first, but it’s actually not recommended by most roofing companies. Flashings are thin pieces of metal used around vents, chimneys, eaves, and other rooftop attachments to prevent water from leaking around them. They are a crucial component in any roofing system, and they do tend to wear out in time. 


If you have the opportunity to replace or install new roofing shingles, it only makes sense to remove the old flashing and replace it with a new application. This ensures the quality of your installation and prevents any possible leaks.


Improper Fasteners


Those nails that hold your shingles in place are called fasteners. Their purpose is to stop the shingles from shifting or moving even in high winds. Fasteners may seem like a small thing to be concerned about, but they play a crucial role in keeping your roof intact. If you want to keep your roof in one piece, you need to make sure you have the right kind of nails and the proper size for the shingles you’re using. If you happen to use nails that are too short, your shingles could flap around or become detached without you knowing it.


Bad Fastener Placement


Aside from getting the right fastener type and size, there’s still the issue of proper installation. If you like to DIY your roofing repairs and installation, you need to make sure that you’re placing the fasteners properly and in the correct places. For example, all nail heads must be placed beneath the overlapping flap of the asphalt shingles. Failure to do so will leave your nails exposed to the elements, making them prone to corrosion.


Improper Moisture Barrier


The moisture barrier is the element of your roof underlayment that ensures that moisture doesn’t seep through the decking and becomes trapped there. If there’s anything, you don’t want to happen to your roof, that’s letting your decking get soaked in water. Wet decking leads to rotting, which undermines your roof as a whole. It can easily cause your shingles to ripple and wear out easily. This is one of the most common causes of roof replacements, which is why you need to avoid this by making sure you have an adequate moisture barrier such as tar paper placed between the shingles.


Conclusion


If you’re planning to start a new roofing project and installing new asphalt shingles, you better take into consideration all these common mistakes so you can avoid them. Any of these mistakes can easily ruin your roofing job and cost you a great deal of time, money, and effort. Make sure you avoid them at all costs. At the end of the day, calling a professional roofing company is still the best option.
