Why Does Your Roof Look Wavy?

You probably don't want your roof to look wavy. Some minor imperfections are normal, but they should not be noticeable enough for you to see from a distance. Wavy roofs have many causes, and most of them are fixable. Some problems may require a teardown or re-do. Continue reading to learn more about wavy roof causes and repair.

Underlayment Issues

Before the roofer can lay new shingles, he or she will need to put down an underlayment layer. This layer, usually made of felt paper, protects the decking from moisture. If the roofer didn't lay the paper right, the roof may look wavy. However, if you had your new roof installed during high humidity or the paper was wet at installation, the wave may be temporary. As the weather dries, you may see the wave clear up.

Shingle Problems

There is an order and procedure to laying down shingles. If they aren't laid the right way, the roof will look strangely wavy. Also, if you have defective shingles, then they may be subject to tears and other issues. This problem will not resolve on its own, and you will need to have the work re-done.

Weak or Damaged Decking

The decking is the base for all your roofing materials. When it is weak or damaged, then it will cause a sag or wave. Rotted and water-damaged wood can cause your roof to have an uneven look. A damaged decking does not look good even with all new roof materials. Plus, you may be more subject to leaks and other serious roof issues.

New Roof Over Old Roof

Re-roofing, or putting new shingles over old ones, can be risky. It takes skill to pull it off so your roof looks good and continues to protect your home. Many roofers recommend against this practice because it can cause more problems than it solves, including a wavy roof. While small repairs are usually not a problem, consider new shingles and underlayment for major roof repairs.

Ventilation Issues

If your attic doesn't have good ventilation, heat, cold, and moisture could build up and damage your decking. The result could be a wavy or uneven look to your roof. You can prevent or correct many of these issues by hiring a qualified and highly-rated roofing company to do the work. A residential roofer can let you know if you have some decking or frame issues before they lay your new roof. They will also lay the roof precisely. If you have a wavy roof, whether it is new or not, contact a roofing expert for more information.

Roofers and the Modern Era

Roofs have been along for just about as long as buildings have been around — thousands of years. However, roofs have changed a lot over time. So have the jobs of roofers. Thousands of years ago, roofers knew how to create bundles of straw and use them to make a roof. This process was known a thatching. These days, however, roofers know how to install shingles, put metal sheets on the roof, and lay tile. These are different skills, and they are all very important skills. Join us in discussing these skills, and the work of roofers in general, on this website.
