What is Peel and Stick Roofing Underlayment?
Peel and stick roofing underlayment is a self-adhering membrane that provides an additional layer of protection beneath roofing materials. Unlike traditional felt underlayment, peel and stick options feature a sticky backing that adheres directly to the roof deck. This provides a watertight seal, minimizing the risk of leaks from ice dams, heavy rain, or wind-driven moisture.
Benefits of Peel and Stick Underlayment
Enhanced Waterproofing
One of the primary advantages of peel and stick underlayment is its exceptional waterproofing capabilities. The adhesive layer seals tightly around nail penetrations, significantly reducing the likelihood of water intrusion compared to traditional underlayment.
Ease of Installation
Installation is straightforward; the product is simply rolled out and pressed into place, making it an ideal choice for DIY homeowners. This ease of use can save both time and labor costs.
Versatility
Peel and stick underlayment can be used in various applications, including eaves, valleys, and low-slope roofs. This versatility allows it to be integrated with other roofing materials seamlessly.
Compliance with Building Codes
Many building codes and roofing manufacturers require the use of peel and stick underlayment in specific areas of a roof to meet warranty guidelines. This ensures that your roofing project complies with local regulations.
Drawbacks of Peel and Stick Underlayment
Higher Cost
While the long-term benefits may outweigh the initial investment, peel and stick underlayment typically costs more than traditional options like asphalt-saturated felt. Homeowners should factor this into their budget.
Limited UV Exposure
Most peel and stick products have a limited lifespan when exposed to sunlight. It’s essential to cover them with roofing materials promptly to avoid degradation.
Installation Considerations
While installation is easier than traditional methods, it still requires careful handling. If not applied correctly, the adhesive can lose its effectiveness, leading to potential leaks.
Applications of Peel and Stick Underlayment
Eaves and Valleys
Peel and stick underlayment is particularly effective in areas prone to ice damming and water accumulation. By applying it in these critical zones, homeowners can ensure their roofs remain watertight.
Low-Slope Roofs
For low-slope roofs where traditional shingles may struggle to shed water, peel and stick underlayment provides a reliable barrier against leaks.
Flashing and Skylights
This type of underlayment is ideal for use around flashing and skylights, where water intrusion can be a significant concern. Its self-sealing properties around nails help maintain a watertight seal.
