How Long Can Shingle Bundles Sit On Roof

How Long Can Shingle Bundles Sit on a Roof Before Installation?

So, you've got your new shingles delivered and they're sitting on your roof. Now you're wondering, how long is too long? Leaving shingle bundles exposed to the elements can significantly impact their lifespan and performance. Let's delve into the ideal timeframe and factors influencing shingle longevity.

Understanding the Risks of Prolonged Exposure

Leaving asphalt shingle bundles on a roof for extended periods exposes them to several potential hazards:

Weather Damage:

• Sun Exposure: UV rays from the sun can degrade the asphalt, making the shingles brittle and prone to cracking. This reduces their lifespan and waterproofing capabilities.
• Moisture: Rain, snow, and even dew can penetrate the packaging, leading to moisture absorption within the shingles. This can cause warping, mildew growth, and affect their ability to adhere properly.
• Extreme Temperatures: Fluctuations in temperature can cause expansion and contraction, potentially damaging the shingle structure.

Physical Damage:

• Wind: Strong winds can dislodge bundles, causing damage and potentially leading to safety risks.
• Foot Traffic: Walking on the bundles can cause breakage and compromise the shingles' integrity.

The Ideal Timeframe: A Balancing Act

While there's no universally agreed-upon number, it's best to install shingles as soon as practically possible after delivery. Ideally, this should be within a few weeks, especially during warmer, more humid months.

However, several factors influence this ideal timeframe:

• Weather Conditions: If you're experiencing consistently unfavorable weather (prolonged rain, extreme heat, etc.), delaying installation until conditions improve is advisable.
• Storage: Proper storage on the roof plays a role. Keeping the bundles covered with a tarp, especially during prolonged exposure, offers some protection.
• Shingle Type: Different shingle types exhibit varying degrees of resistance to weather damage. Consult the manufacturer's instructions for specific recommendations.

Minimizing Risks: Best Practices

To protect your investment, consider these precautions:

• Schedule Installation Promptly: This is the single most important factor in preserving shingle quality.
• Proper Storage: If delays are unavoidable, cover the bundles with a waterproof tarp to minimize exposure to the elements. Ensure the tarp is secured properly to prevent wind damage.
• Manufacturer Recommendations: Always refer to the shingle manufacturer's guidelines for specific handling and storage recommendations.

Signs of Damaged Shingles:

Before installation, carefully inspect the shingles. If you notice any signs of:

• Cracking
• Warping
• Discoloration
• Mildew

It may be necessary to contact your supplier for replacement.

Conclusion: Time is of the Essence

While a few weeks of exposure may not always result in significant damage, minimizing the time shingles spend on your roof before installation is crucial. Prioritize prompt installation, and take steps to protect the bundles during temporary storage. Doing so ensures the longevity and optimal performance of your new roof.
