As the seasons change and the weather puts roofs to the test, homeowners in American Fork, Utah often notice a troubling sign: split shingles. At first glance, a few cracks might seem minor. But in reality, they’re early warning signs that your roofing system might be at risk. Understanding the root causes of shingle splitting is key to preserving the structural integrity of your home and avoiding costly repairs.
From thermal stress to poor installation, several factors contribute to shingle damage in Utah County. In this guide, we’ll break down the most common culprits, how they affect your roof in American Fork’s unique climate, and what you can do to prevent future issues.
What Are Split Shingles?
Split shingles refer to asphalt roofing shingles that crack, tear, or break apart, usually down the middle. These splits can allow water to penetrate beneath the surface, ultimately leading to leaks, rot, and structural damage if left unaddressed. For homeowners in American Fork, this is a particularly common concern due to fluctuating temperatures, heavy snowfalls, and summer heat.
The Real Reasons Shingles Split on American Fork Roofs
1. Thermal Expansion and Contraction
American Fork experiences hot summers and cold winters, which makes thermal cycling a major contributor to shingle splitting. As shingles expand during the day and contract at night, repeated stress causes cracking over time. This is especially common in older roofs or shingles made of low-grade asphalt.
2. Improper Installation Techniques
Shingles that are nailed too tightly or misaligned can’t move as needed during temperature shifts. This rigidity makes them prone to cracking under stress. An experienced roofing company like Rooftek understands the importance of correct nailing patterns and ventilation design to prevent such issues.
3. Old or Worn-Out Shingles
Asphalt shingles typically last 15–30 years. In areas like American Fork, roofs are exposed to UV rays, hail, and snow—accelerating wear and tear. Aging shingles become brittle and are more susceptible to splitting even under normal conditions.
4. Poor Attic Ventilation
When attics trap heat and moisture, it creates a high-temperature zone under the roof deck. This accelerates the aging of shingles and contributes to cracking from below. Rooftek provides inspections that include evaluating your attic’s airflow system to determine if poor ventilation is contributing to shingle damage.
5. Manufacturer Defects
Although rare, certain shingles are prone to splitting due to factory defects. These usually show signs of damage within the first few years of installation. If your American Fork home was built or re-roofed within the last five years and you’re seeing cracked shingles, a defective batch may be to blame.
6. Hail and Wind Damage
Hailstorms and high winds are not uncommon in Utah County. Impact from hailstones can cause surface granule loss and underlying cracks. Wind uplift can also stress shingles, causing them to crease or split. If your home has recently endured a storm, it’s best to schedule a free inspection from your nearest Rooftek location in American Fork.
7. Improper Roof Layering
Installing new shingles over old ones—known as overlaying—can create uneven surfaces and prevent proper sealing. This increases the likelihood of moisture buildup and premature cracking. Rooftek always recommends full tear-offs and proper roof replacements in American Fork for lasting results.
8. Inconsistent Roof Maintenance
Regular maintenance is crucial in spotting small issues before they become major repairs. Ignoring routine inspections allows small cracks to go unnoticed until they cause leaks or structural problems. Routine inspections by a qualified roofer in American Fork help extend the lifespan of your roof.
Why American Fork Roofs Are Especially at Risk
American Fork’s location along the Wasatch Front means roofs here are subjected to a wide range of environmental stressors. Between heavy snow accumulation in winter and the dry, hot summers, roofing systems are often stretched to their limits. Sudden temperature shifts—such as a spring day where it snows in the morning and warms up by afternoon—make thermal expansion and contraction a daily challenge.
Local regulations and climate data available on the American Fork City website provide further insight into how homes must be built to meet regional needs, including roofing materials and insulation standards. That’s why it’s so important to work with contractors who specialize in this area and understand what homes in this region endure.
How to Prevent Shingle Splitting on Your Roof
Schedule Annual Roof Inspections
A yearly check-up can reveal signs of wear before they become emergencies. Rooftek offers comprehensive inspections and provides actionable repair recommendations tailored to the American Fork climate.
Invest in High-Quality Shingles
Opt for roofing materials designed for high UV resistance and flexibility in cold temperatures. Our team at Rooftek only uses top-tier products with long-lasting warranties.
Improve Attic Ventilation
Proper airflow can reduce the internal temperature of your roof, preventing excessive heat build-up and extending the life of your shingles.
Avoid DIY Repairs
Shingle installation is precise work. Improper techniques can actually cause more damage. Leave it to professionals with experience in replacing roofs in American Fork.
Get Ahead of Weather Damage
Following a storm, hail, or wind event, schedule a post-storm inspection. Even invisible damage can lead to future splitting if left unattended.
The Cost of Ignoring Split Shingles
Leaving split shingles unattended can lead to water intrusion, insulation damage, mold, and even structural degradation. The cost to repair a few shingles early on is far less than a full roof replacement or extensive interior repair. With Rooftek’s free inspections and emergency roofing services, there’s no reason to let a minor crack become a major problem.
