Shingles are the first line of defense for your roof. If your singles are in rough shape or if there are holes in your shingle layer, you are going to have issues. When it comes to re-roofing your home, it can be difficult to determine if it is time to re-roof or not. We can help you decide.

 Am I a Good Candidate for Re-Roofing?

In the United States, it is not recommended that there be more than two layers of shingles on your roof at any given time. If you are having your roof done professionally, they are not allowed to put more than one layer of shingles over another. The reason for this is that the more layers of shingles that are added, the harder it is to spot damage and find issues before they become major and cause further damage to the roof itself.

The more layers of shingles on the roof, the harder it is to fix the shingles to the roof as well, which can lead to lifting, shingles coming off, and the roof becoming more and more damaged. Two layers of shingles are as much as can be secured to the roof properly and as much as can be put down so that the roofer can spot damage and correct it.

When To Consider Re-Roofing?

Most shingle roofs are good for up to ten years if they are not subjected to very harsh conditions. If the roof is not subjected to very high heat and very intense cold, if there have not been any major weather events like wind or ice storms, and if there has been no direct damage, these roofs can last for years.  Metal roofs last even longer.

If you notice that there are leaks, if you can see that the shingles are old or are damaged, and if you suspect that your roof is very old, you may need to have it redone. You can contact a roofing company and have a free estimate to see what might work for your roof and what the roofers feel will be best for your particular issues.

They can look at your roof, tell you if a full replacement is better or if a repair is possible, and help you determine what sort of work will benefit you most. A roof is a very important part of any home; making sure your roof is working properly is a must and can make all the difference.
