What Causes Shingle Curling or Cupping?

Roof nail pops issues occur for multiple reasons. By understanding these reasons, you can prevent this problem in the future. Here are the significant causes you need to follow:

• Improper Installation

  Improper roof installation is one of the significant reasons why roof nails pop. This issue occurs if nails are not properly fixed or at the wrong angle, which can easily damage the roof. Homeowners should not ignore this issue at any cost, as poor installation can lead to pulling the nails that are not properly attached to the wood sheathing or sheathing boards, weakening the hold and allowing the nail shank to pop.   

• Wrong Nails

  If a roofing company is not professional during roof installation and fixes nails at different angles, it can cause damage. If they fix short and smooth nails, these do not grip the decking well. The most recommended option is to use ring shank nails or long ring shank nails, which extend the roof’s lifespan over time.

• Roof Shrinkage and Expansion

  During summer, the roof attic is exposed to maximum heat, which causes the decking to expand and contract. As a result, roofing materials shift, and nail grips become loose, causing visible nail pops.

• Poor Attic Ventilation

  Another significant cause of roof nail pops is poor attic ventilation or inadequate ventilation. Due to excessive heat, your roof airflow can compromise which affects the roof decking causing swelling. This swelling situation can push nails out. Fortunately, you can simply regulate temperature and minimize the movement of the nails by leveraging soffit vents, attic fans, and gable vents.

• Weather Damage

  The weather has a significant impact on your roof’s health. Since your roof may be exposed to different weather conditions, such as wind-driven rain, high winds, ice dams, and heavy snow, this situation can compromise your roofing system.

Tips About How To Prevent Roof Nail Pops

If you perform inspection roof nail pops on time, you don’t need to deal with costly roof repair, roof leaks, or roof replacement. With proper planning and inspection strategies, you can prevent this common problem. Reading the five essential strategies below can help to maintain your roofing system in optimal shape.

 

1.  Use the Right Roofing Materials

The quality of roofing nails is most important during roof installation to prevent nail pops. It is recommended to use ring shank nails with a strong grip nail shank for roof decking. You must use durable and powerful long ring shank nails for dealing with high wind areas. These nails perform well and cause a minor shift in the wood sheathing.

However, wrong nails can be pulled out during high winds and cause roof shrinkage, leading to roof nail pops. To prevent this, you need to hire a professional roofing company that uses the perfect type and size of nails.

 

2.  Hire Skilled Contractors

Poor roof installation causes major roofing problems. If you can’t handle regular roofing inspection, you need to choose a quality roofing contractor with experience in house crews to ensure high-level craftsmanship. This professional team understands where to put the shingle nail at the correct angle.

The primary cause of roof nail pops is improper nailing, which causes sheathing boards or nail pushes upward by inexperienced workers. Thus, they know how to secure and manage awkward areas sealed properly on your roof.

 

3.  Ventilate Your Attic

Homeowners may not focus on attic ventilation, but extending the roof’s lifespan is crucial. Inadequate airflow, moisture, and heat can cause roof decking during summer and winter, leading to wood sheathing and loose the grip of your roofing nails.

The roof should have proper airflow with the installation of attic fans, soffit vents, and gable vents. These roofing materials can maintain the attic’s internal temperature and reduce the risk of ice dams, which cause roof damage and shingle lifts. Therefore, you need to use an adequate attic ventilation system to prevent roof nail pops and make your living space comfortable.

 

4.  Schedule Regular Roof Inspections

Regular roof inspection is the most recommended approach to dealing with roofing problems, most importantly, roof nail pops. Without regular inspection, you may face roof leaks and hidden damage to your entire roof.

Make a proper plan to inspect your roof at least once a year after serious weather situations like heavy rain, strong winds, or snow. A thorough inspection can help to identify the hole, damaged shingles, and signs of roofing system wear. During a roof tune up, a roofing company can fix issues before nails lift and prevent expensive roof repair.

 

5.  Use High-Quality Roofing Materials

If you live in an extremely hot and rainy region, you must invest in quality and durable roofing materials such as asphalt roof shingles for high winds and flat roofs to reduce roofing problems. Indeed, these materials can face serious weather damage, wind-driven rain, and even standing water. Quality materials can increase the life of the sealant bond, which provides protection around shingle nails.
