Missing Shingles: Why It Happens And What To Do

Posted on: 2 June 2015


Stormy weather can cause problems for homeowners.  Every year severe weather tears across the country and causes damage to homes.  It doesn't take a tornado or hurricane to cause serious problems.  Strong winds alone can rip shingles from roofs, which in turn can lead to more severe issues.

What causes random shingles to blow off?

Strong winds won't usually blow the entire roof off but might blow individual shingles off the roof.  Most shingles are meant to withstand very heavy winds, and when random shingles blow off there is likely an underlying issue. 

  • Faulty shingles: Just like many products, there is always the possibility of a faulty batch of shingles.  In order to find out if the shingles on your roof have been recalled, contact the person or company who roofed your home.  If shingles have been recalled, you are likely able to get your roof replaced without a substantial bill. 
  • Poor installation: There is a possibility that your shingles were installed incorrectly.  Some common installation problems are that nails were not properly placed on the shingle or nails weren't long enough.  Asphalt shingles also have a strip of strong adhesive that is meant to seal the shingles together.  The sun heats the adhesive and causes it to stick to the other shingles.  If shingles don't get the appropriate amount of sun and heat after installation, they are more likely to fall off.
  • Old roof: Your roof isn't meant to last forever.  Most roofs with asphalt shingles should last about 20 years.  Shingles blowing off might just be a sign that your roof is old and it's time to get a new one. 

What are the consequences of not replacing the shingles that blow off?

Even though a couple random shingles may not seem like that big of a deal, there can be serious repercussions if you don't replace them.  These consequences can be very expensive.

  • Your roof will rot and weaken.  Instead of hitting the shingles, which protect your home, the elements will hit the exposed part of the roof and cause it to deteriorate.  This will cause leaking, mold and other water problems.  In this case, what is originally a quick fix becomes an expensive and pricey repair.
  • Homeowner's insurance won't cover a new roof.  Once the roof shows signs of deterioration due to neglect, there is a good chance that homeowner's insurance will not cover a necessary replacement of the roof. 
  • If you try to sell the house, replacing the roof will be expensive.  If you have missing parts of the roof, you will need to repair them before you are able to sell the home.  A house won't pass an inspection with a damaged roof and shingles missing.  If further damage has been done to the roof and insurance won't cover it anymore, this can be extremely expensive and can be a deal breaker in real estate transactions.

What are the best ways to repair missing shingles?

It isn't necessary to redo the entire roof if the only problem is a few missing shingles.  These shingles can usually be replaced and the problem is solved.  If you are handy, you can do it yourself.  Some contractors will do it for a great deal.  There may be a warranty, so you don't have to pay out of pocket.  If the roof is older than 15 years or it has other problems, a full replacement of the roof may be in order.  Contact a company like CJ Scotti Services if you think your roof needs to be repaired or replaced and you can't do the repairs yourself.
