Three Reasons Why You Shouldn’t Layer Your Roof

Maybe your warranty is expired, you have damaged shingles, or your roof just needs an update. But it’s time for a new one. And for many homeowners, the next question becomes, should you replace your roof totally, or add a layer of shingles on top of the existing one?

While doubling up might sound like a good idea – if one layer is good, wouldn’t two be even better? Here are three reasons you might want to reconsider.

 

  1. Your building codes may require that you strip your roof. While building codes vary from state to state and even zip code to zip code, many require that when a roof is replaced, it must first be stripped down to the sheathing. Much of this has to do with weight. While most homes are strong enough to support a double layer of shingles, with some of today’s heavier laminated shingles, two layers may over stress rafters and your home’s structural components. Also, many manufacturer’s warranties don’t cover a roof that is doubled up. And so while you may be thinking you are getting more protection, in reality, you may just be getting a whole lot less.
  1. You can’t check for damage. While damage to your roofing shingles is easy to spot, damage due to a roof leak that goes under your shingles, into your underlayment and perhaps even inside your walls is much more easily overlooked – especially if you don’t strip your roof down to the sheathing. And while finding more damage than you thought you had is never fun, it is ALWAYS better to find rot, water damage, and mold sooner rather than later.
  1. You may have to replace your sheathing. While the process of stripping down to the sheathing involves replacing your roof underlayment and shingles, it, in some cases also means replacing damaged sheathing. Because let’s say you had a leak that saturated your underlayment and allowed moisture to settle on your sheathing. In this case, replacing just the underlayment and shingles will do nothing to mitigate the damage to your sheathing. And left untreated, roof damage only gets worse.  

 

As always the best place to start when considering replacing your roof is with a licensed professional roofing contractor who can not only inspect your roof for a damage, but also recommend the best roofing options for your home.
