Roof Racking? What is it and why is it bad
Architectural asphalt shingles are a popular roofing choice due to their ease of installation, commonality, and affordability. However, the way they are installed can significantly impact their performance and lifespan. One issue we see on even brand-new roofs is roofs installed in a racking pattern. While this technique may seem easier to install and fine, there are several reasons why it’s not the proper way to install architectural asphalt shingles.
1. Nailing Issues – Roofers like to move fast and often have large crews. A racking pattern requires you to go back to previously installed areas and add nails. Because of this, it is very common to see missed areas of nails from lack of attention to detail or communication. Missing nails often lead to failures and other problems.
2. Other Installation Issues – If you didn’t read one part of the instructions, your problem didn’t read any of them. I see racking patterns combined with other installation issues routinely, things like using the wrong amount of nails, nailing in the wrong place, using the wrong underlayment, improperly flashing areas, and other issues are far more likely in a racked roof and may lead to total replacement.
3. Manufacturer Warranties – A manufacturer typically warranties the product when it comes to roofing. While they won’t necessarily void their warranty due to a racking issue, they don’t cover any issues with installation. As a homeowner, your “lifetime guarantee” could be worthless if you have one on an improperly installed roof. If you used a contractor who didn’t install the material properly they are unlikely to offer you any recourse…Probably shouldn’t have gone with the cheapest option.
4. Repairability – If you have a leak it may result in significant damage. Assuming the problem may be repairable, most qualified roofers are not going to touch an improperly installed roof without replacing it because they would then “own” any other issues that result. Even with minor repair issues, roofers are likely to recommend complete replacement.
5. Aesthetics – Not really my biggest concern but when I called the manufacturers about this issue, they did mention it is at least partially the look that results as an issue and it is somewhat cosmetic in nature.
Just because a roof is installed “Racked” does not mean it needs replacement. It is important to know however, it is much more likely to have issues and replacement should definitely be considered especially when repairs are needed. Regardless of what type of roof you have the number one thing is always going to be installation. Our home inspections can help determine if your home components are installed properly and this can often be just as important as age, material, or condition. Hiring a professional is so important and that goes for contractors and home inspectors alike!!!
