Buying a new home can be exciting, but it can be a lot of work. The older the home is, the more work you must do to ensure you are not buying a money pit. Purchasing a home that has a history requires doing your own homework. Since the roof is one of the most expensive parts of the home, it is important to do a full inspection on the roof. One of the most common roofing types is asphalt shingles. With shingles, you can expect issues to arise over time. Replacing an asphalt roof could cost you about $120 to $140 per square foot. The last thing you want to do is buy a home and discover that you need to spend thousands of dollars replacing the roof. Instead, here are some things to look for.
Unorganized Shingle Rows
When inspecting the roof on the house, you should see that the shingles are lined up in neat rows. If you see that the rows are looking anything but straight, this could be a sign that the shingles are starting to slide. Asphalt shingles are composed of two layers. They contain a tar strip during packaging in an effort to hold the layers together before they are installed. When roofing contractors go to install the shingles, they should be placing nails in the tar line to ensure it is applied properly. Otherwise, the sun can heat up the tar and cause it to lose some its tackiness. This results in the shingles separating and sliding.
Another issue you want to look for is patched places showing that the homeowner had work done on the home. There are numerous reasons why a roof would need to be patched. It is important to understand what the issue was before so you can determine if the issue has been properly corrected. In order to identify a patched roof, you will notice that the shingles will look a little different than the rest of the house. It is important to ask the buyer about the previous issues with the roof.
Another common problem with asphalt roofs is curling shingles. There are several reasons for curling shingles. This could be a moisture issue, improper ventilation, tall nails, or lack of coating. Rafter vents can help prevent and remedy any curling coming from your shingles due to ventilation. If the shingles have a lack of back coating, you will want to remove the curled shingles and replace them also adding a good layer of coating. If the problem is stemming from tall nails, you will want to take off the existing nails and re-nail each one.
