When it comes to installing roofing underlay, many homeowners and professionals wonder if staples are a suitable option. Roofing underlay, also known as roofing felt or tar paper, is a protective layer installed beneath shingles or tiles on a roof. This article aims to address the question of whether staples can pierce roofing underlay and the potential consequences of using staples during installation.
Understanding Roofing Underlay:
Roofing underlay is a crucial component of a roofing system, providing several benefits. It acts as a waterproof barrier, protecting the roof from water damage caused by leaks or condensation. Additionally, underlay helps to prevent the transfer of heat and cold between the roof and the interior, thereby helping to maintain a comfortable temperature inside the building. Furthermore, underlay provides an additional layer of protection against wind-driven rain and the potential infiltration of debris.
The Use of Staples in Roofing Installation:
Staples are commonly used during various stages of roofing installation, including securing underlay. However, there are concerns regarding their capability to pierce roofing underlay, potentially compromising its effectiveness. To better evaluate this concern, it is important to explore the types of staples used and their potential impact on the underlay.
Types of Staples:
1. Standard Staples:
Standard staples, typically used for office or household purposes, are not suitable for roofing installation. These staples have short legs and lack the strength required to penetrate roofing underlay effectively. Attempting to use standard staples for roofing may result in insufficient attachment and potential damage to the underlay.
2. Roofing Staples:
Roofing staples are specifically designed to withstand harsh weather conditions and secure roofing materials effectively. These staples are generally manufactured from galvanized steel, making them more durable and resistant to corrosion. Unlike standard staples, roofing staples have longer legs that allow for proper penetration of roofing underlay, ensuring a secure installation.
Consequences of Using Staples Improperly:
If standard or inadequate staples are used during roofing underlay installation, several consequences may arise:
1. Compromised Waterproofing:
Insufficient penetration or puncture in the underlay caused by inadequate staples can compromise the waterproofing capabilities of the roofing system. This may lead to water leaks, potentially causing damage to the roof structure and interior of the building.
2. Reduced Wind Resistance:
Properly secured underlay plays a crucial role in enhancing a roof’s wind resistance. Inadequate stapling can result in underlay displacement during high winds, reducing the roof’s ability to withstand wind-driven rain and potential damage.
3. Increased Risk of Mold and Rot:
When underlay is not adequately secured, it can become loose or wrinkled. This may allow moisture to accumulate, creating conditions favorable for the growth of mold, mildew, and rot within the underlay and potentially spreading to other parts of the roof and the underlying structure.
Best Practices for Proper Staple Usage:
To ensure the proper installation of roofing underlay, the following best practices should be followed:
1. Use Roofing Staples:
When securing roofing underlay, it is crucial to use roofing staples specifically designed for this purpose. These staples are longer, stronger, and resistant to corrosion, ensuring a secure attachment that won’t compromise the integrity of the underlay.
2. Proper Stapling Technique:
Staples should be applied at adequate intervals to ensure effective attachment. Generally, staples should be inserted every 6 to 9 inches along the edges of the underlay and spaced approximately 12 inches apart across the field.
3. Consider Alternative Attachment Methods:
In some cases, roofing nails or cap nails might be preferred over staples for attaching underlay, particularly in areas prone to high winds or severe weather conditions. These alternative attachment methods offer increased reliability and strength.
While staples are commonly used during roofing installation, it is crucial to ensure the use of appropriate roofing staples to avoid compromising the roofing underlay. Properly secured underlay provides essential protection against water damage, wind-driven rain, and the infiltration of debris. Following best practices and using roofing staples specifically designed for this purpose will contribute to a more durable and effective roofing system, providing long-lasting protection for your home or building.
