How to Fix Curling Shingles

9 minutes

Noticing curling shingles on your roof? It is time to take immediate steps to prevent further deterioration. Ignoring the curling shingles could lead to leaks, resulting in more significant issues. This guide will outline the process of fixing the curling shingles on your roof. 

Identifying the Problem: Curling Shingles 

Maintaining the integrity and longevity of your roof involves regular inspections for curling shingles. This issue can indicate underlying problems that could escalate into extensive damage and expensive repairs if overlooked. We will talk about the signs of curling shingles, what causes this issue, and why it is crucial to address it promptly in this section. 

Visible curling or cupping of shingle edges is a clear indication of curling shingles. This can lead to a distorted and uneven look on your roof. You might also notice that the shingles are not lying flat against the roof surface and are, instead, curling upwards. 

Several factors can contribute to shingle curling. Aging and exposure to elements like sunlight, heat, and moisture can cause shingles to deteriorate and curl. Poor ventilation in the attic can also contribute to this problem, leading to excessive heat buildup in the roof. 

It is crucial to address curling shingles promptly to prevent further damage and potential roof leaking. Curling shingles can expose your roof to water intrusion, leading to rot, mold growth, and structural damage. Curled shingles are also more susceptible to wind uplift, increasing their chances of being blown off during storms. 

If you observe curling shingles on your roof, it is advisable to consult a professional roofing contractor like DaBella for a comprehensive inspection. They have the expertise to identify the root causes of shingle curling and provide appropriate solutions. Be it a simple repair or a full roof replacement, DaBella offers high-quality roofing materials and professional installation services to ensure your roof is in excellent condition. 

Steps to Repair Curled Shingles 

If you have spotted curling shingles on your roof, it is crucial to address the problem promptly to avoid further damage. Luckily, you can handle this task yourself with the right materials and a step-by-step process. Here is what you will need and how to do it: 

Materials required for shingle repair: 

  • Replacement shingles 
  • Roofing nails 
  • Hammer 
  • Roofing adhesive 
  • Caulk gun 
  • Utility knife 
  • Ladder 
  • Safety harness 

Step-by-step process to fix curling shingles: 

  1. Begin by carefully removing the damaged shingle. Use a pry bar or a hammer to lift the shingle tabs and loosen the roofing nails. 
  1. Once the damaged shingle is removed, clean the area, and ensure no nails or debris are left behind. 
  1. Apply a generous amount of roofing adhesive to the back of the replacement shingle and carefully slide it into place. 
  1. Secure the replacement shingle in position by hammering roofing nails into the corners. Make sure to nail above the adhesive strip to prevent water seepage. 
  1. Finally, seal the edges of the shingle with roofing adhesive for extra protection against water infiltration. 

Preventive measures to avoid future shingle curling: 

  • Regularly inspect your roof for signs of damage or curling shingles. 
  • Trim overhanging tree branches to prevent them from rubbing against the roof and causing shingle damage. 
  • Ensure your attic is properly ventilated to regulate temperature and reduce moisture buildup. 
  • Consider installing an ice and water shield beneath your shingles for added protection against water damage. 

When Is It Time for a Professional Roof Replacement? 

Homeowners often question whether a repair is sufficient for fixing curling shingles or if a full roof replacement is necessary. While minor shingle repairs can be a cost-effective solution, there are certain signs that suggest a roof replacement might be a better choice. 

The decision between shingle repair and roof replacement depends on the extent of the damage. If only a few shingles are curling or damaged, it may be feasible to replace them and restore the roof’s integrity. However, if a significant portion of the shingles are curling, or if the underlying roof structure is compromised, it might be time to consider a professional roof replacement. 

Signs that suggest a roof replacement may be necessary  

  • Multiple Curling or Missing Shingles: When shingles start to curl or go missing, it is often a visible sign of wear and tear on the roof. Curling can occur due to prolonged exposure to the elements, and missing shingles leave the roof vulnerable to water damage and leaks. 
  • Extensive Water Damage or Leaks: Water stains on ceilings or walls, or evidence of water pooling in the attic after rain, can indicate significant roof damage. Leaks often start small but can quickly escalate, causing extensive damage to the structure and interior of the home if left unaddressed. 
  • Sagging or Uneven Roof: A sagging or uneven roofline is a clear indication of structural issues that require immediate attention. It can be caused by several factors, including weakened roof supports, excessive weight from snow or debris accumulation, or water damage compromising the roof’s integrity. 
  • Visible Signs of Rot or Decay: Rot or decay on the roof surface or in the underlying structure can weaken the roof’s ability to provide adequate protection. It is often caused by prolonged exposure to moisture, which can compromise the integrity of the roof and lead to more severe issues over time. 
  • Age of the Roof (typically over 20-30 years old): As roofs age, they become more susceptible to damage and deterioration. Even with proper maintenance, the materials used in roofing systems have a limited lifespan. Once a roof reaches its expected lifespan, it is essential to assess its condition regularly and consider replacement to prevent potential issues and ensure the safety of the home. 

While repairing individual shingles can tackle minor issues, a professional roof replacement offers numerous benefits. It ensures that the entire roof is in top condition, providing durable protection for your home. Moreover, a new roof can enhance energy efficiency, improve curb appeal, and increase your property’s value. 

When considering a roof replacement, it is essential to hire a reputable roofing contractor like DaBella. Our experienced professionals will assess your roof’s condition, provide expert recommendations, and perform a seamless roof replacement using high-quality materials. 

Frequently asked Curling Shingle Questions 

Why are my Shingles Curling?  

Shingles can curl due to several factors, including age, poor installation, improper ventilation, low-quality materials, excessive moisture, and extreme weather conditions. Over time, shingles naturally lose flexibility and dry out due to exposure to sunlight, heat, and weather elements, leading to curling.  

Improper installation, such as inadequate fastening or alignment, can also contribute to premature curling. Inadequate attic ventilation can cause heat and moisture buildup, accelerating the aging process of shingles.  

Additionally, low-quality materials may be more prone to curling and deterioration. Excessive moisture from leaks or condensation, as well as exposure to extreme weather conditions like high winds, can stress shingles and cause them to curl. Regular roof inspections, proper installation, adequate ventilation, and using high-quality materials are essential for preventing or addressing shingle curling effectively and maintaining the integrity and longevity of the roof. 

Can I Shingle over Curled Shingles?  

Firstly, placing new shingles over curled ones does not address the underlying issues causing the curling. Curling shingles often signal aging, poor ventilation, or moisture-related problems, and merely covering them can worsen these issues. 

Secondly, adding new shingles over curled ones increases the weight on the roof. This added weight can strain the underlying structure, potentially causing more damage or compromising the roof’s integrity. 

Moreover, this method can result in an uneven roof surface and affect the overall appearance of the roof. The unevenness caused by the curled shingles underneath may lead to an unprofessional-looking finish. 

Instead of layering new shingles over curled ones, it is advisable to address the root causes of the curling. This may involve removing the old shingles, inspecting the roof structure for damage, fixing ventilation or moisture issues, and properly installing new shingles. Consulting with a professional roofer can help determine the best approach for dealing with curled shingles and ensuring the long-term health of your roof. 

Will Curled Shingles Leak?  

Curled shingles can indeed lead to leaks and other roofing problems. When shingles curl, they lose their ability to provide a secure and watertight seal on the roof. This loss of seal allows water to seep underneath the shingles and penetrate the roof structure. 

The curled edges of the shingles create gaps and spaces where water can easily infiltrate, especially during periods of heavy rain or snow. Once water gets underneath the shingles, it can travel along the roof’s surface, causing damage to the underlying materials and potentially leading to leaks inside the home. 

Additionally, curled shingles are more prone to wind uplift, where strong winds can catch the curled edges and cause lifting, further exposing the roof to water intrusion and damage. 

Therefore, if you notice curled rotten shingles on your roof, it is essential to address the issue promptly to prevent potential leaks and water damage. This may involve repairing or replacing the curled shingles and addressing any underlying issues contributing to the curling, such as poor ventilation or moisture buildup. Regular roof inspections and maintenance can help identify curled shingles early and prevent them from causing severe damage to your roof and home.
