Peel And Stick Roofing: Pros, Cons & Installation

Peel and stick roofing is a popular, DIY-friendly alternative to traditional asphalt shingles, offering a straightforward installation process and a durable finish. This guide will dive deep into what peel and stick roofing entails, its benefits and drawbacks, and how to properly install it for a long-lasting roof.

What Exactly is Peel and Stick Roofing?

Peel and stick roofing, often referred to as self-adhering roofing or granulated rolled roofing, is a type of roofing material that comes in large rolls. Unlike traditional shingles that require nails and adhesive strips, peel and stick products feature a factory-applied adhesive on the back. You simply peel off a protective backing and stick the material directly onto the roof deck.

These products are typically made from asphalt, fiberglass, and a granulated surface that resembles traditional shingles. They are designed for low-slope or flat roofs, as well as for use as an underlayment for other roofing materials.

The Composition of Peel and Stick Materials

Understanding the layers of peel and stick roofing can help you appreciate its durability:

• Top Layer: This is usually a mineral granule surface, similar to asphalt shingles, which provides UV protection and aesthetic appeal.
• Asphalt/Polymer Layer: A thick layer of asphalt or a polymer-modified asphalt provides the waterproofing.
• Reinforcement: A fiberglass or polyester mat offers strength and dimensional stability.
• Adhesive Layer: This is the crucial self-adhering component, activated by pressure.
• Release Liner: A protective film that is removed just before installation.

Advantages of Choosing Peel and Stick Roofing

Peel and stick roofing offers several compelling benefits that make it an attractive option for many homeowners and contractors.

Ease of Installation

Perhaps the biggest advantage is the simplified installation. The self-adhering nature eliminates the need for torches or hot asphalt, significantly reducing installation time and labor costs. This makes it a viable option for DIY enthusiasts.

In our experience, a typical DIYer can cover a small to medium-sized roof section in a single weekend, whereas a professional crew can complete larger roofs much faster than with traditional shingles.

Cost-Effectiveness

When comparing material costs alone, peel and stick roofing can be more affordable than high-end asphalt shingles or metal roofing. The reduced labor costs due to faster installation further enhance its cost-effectiveness. — Olive Branch Homes For Rent: Find Your Perfect Place

Durability and Weather Resistance

Modern peel and stick products are engineered for excellent durability. They offer strong resistance to:

• Water: The seamless application creates a highly waterproof barrier.
• Wind: When properly installed, they can withstand significant wind uplift.
• UV Rays: The granule surface protects the underlying asphalt from sun damage.
• Impacts: They offer decent protection against hail and falling debris.

Versatility for Low-Slope Applications

Peel and stick is an ideal solution for low-slope (1/12 to 2/12 pitch) or flat roofs where traditional shingles are not suitable. It provides a reliable, continuous waterproof membrane.

Aesthetic Options

While historically seen as a utilitarian material, many peel and stick products now come with attractive granule colors and patterns that can mimic the look of traditional architectural shingles, improving curb appeal.

Potential Drawbacks of Peel and Stick Roofing

Despite its advantages, peel and stick roofing isn't without its limitations. It's crucial to consider these before making a decision.

Durability Compared to Traditional Shingles

While durable, peel and stick roofing may not offer the same lifespan as high-quality architectural asphalt shingles or premium materials like metal or slate. Most manufacturers offer warranties in the 15-30 year range, whereas some asphalt shingles can last 30-50 years.

Sensitivity to Temperature During Installation

The adhesive needs a specific temperature range to properly bond. Installation in extreme cold can compromise the adhesion, while excessively hot temperatures can make the material difficult to handle and potentially lead to premature softening.

It's generally recommended to install peel and stick roofing when ambient temperatures are between 40°F and 85°F (4°C and 29°C), although specific product guidelines should always be followed.

Potential for Punctures

While resistant, the material can be more susceptible to punctures from sharp objects or heavy foot traffic compared to thicker, more robust roofing systems. Careful installation and maintenance are key.

Limited Availability and Brand Variety

You might find fewer brands and styles of peel and stick roofing compared to the vast array of traditional asphalt shingles available at major home improvement stores.

When is Peel and Stick Roofing the Right Choice?

Considering the pros and cons, peel and stick roofing is an excellent option for:

• DIY Roofers: Homeowners looking to save on labor costs and undertake a manageable roofing project.
• Low-Slope or Flat Roofs: Where other roofing materials are not suitable.
• Sheds, Garages, and Outbuildings: Smaller structures that don't require the longest possible lifespan.
• Temporary Roofing Solutions: As a cost-effective option for structures that might be replaced in the near future.
• Underlayment: Providing an extra layer of protection beneath shingles or metal roofing.

How to Install Peel and Stick Roofing: A Step-by-Step Overview

Proper installation is paramount for the performance and longevity of peel and stick roofing. Always consult the manufacturer's specific instructions for the product you are using.

Step 1: Prepare the Roof Deck

• Inspect: Ensure the roof deck is clean, dry, and free of debris, old nails, and loose boards. Any imperfections will telegraph through the roofing material.
• Repair: Replace any rotten or damaged sections of the plywood or OSB decking.
• Smooth: Sand down any rough spots or high nails.
• Underlayment: For low-slope applications, a robust underlayment like synthetic felt or a self-adhering ice and water shield is often required as a base layer.

Step 2: Install Drip Edge and Flashing

• Drip Edge: Install metal drip edge along the eaves and rakes (sides) of the roof. This directs water away from the fascia and into the gutters.
• Flashing: Install appropriate flashing around vents, chimneys, skylights, and valleys. This is a critical step for preventing leaks.

Step 3: Laying the First Course

• Starter Course: Many manufacturers recommend a specific starter strip along the eaves. This often involves cutting a roll into strips or using a dedicated starter product.
• Positioning: Carefully unroll the first course of peel and stick material, aligning it with the edge of the roof. Ensure it overhangs the fascia slightly (per manufacturer's spec).
• Peel and Stick: Peel back a few feet of the release liner. Press the material firmly into place, working from the center outwards to avoid wrinkles and air bubbles.
• Roll and Adhere: Once positioned, use a hand roller or a flooring roller to apply firm, even pressure across the entire surface of the installed section. This ensures proper adhesion.

Step 4: Subsequent Courses

• Overlap: Each subsequent course should overlap the previous one according to the manufacturer's specified amount (typically 6 inches or more).
• Stagger Seams: Stagger the vertical seams between courses to prevent a continuous line of weakness.
• Cutting: Use a sharp utility knife to cut the material to fit around obstructions and at the edges.
• Seam Sealing: For added protection, especially on low-slope roofs, consider using a lap sealant or roofing cement along the seams and edges, as recommended by the manufacturer.

Step 5: Finishing the Roof

• Ridge Cap: Install a dedicated ridge cap material or cut strips from the main roofing rolls to cover the peak of the roof, ensuring proper overlap and adhesion.
• Final Inspection: Walk the roof and check for any loose edges, bubbles, or improperly adhered areas. Make any necessary corrections.

Maintenance and Longevity

To maximize the lifespan of your peel and stick roof:

• Regular Inspections: Periodically check for any signs of wear, damage, or loose material, especially after severe weather.
• Keep Clean: Remove any debris, leaves, or moss that accumulates on the roof.
• Avoid Foot Traffic: Minimize walking on the roof, and if necessary, use protective mats or boards.
• Prompt Repairs: Address any minor damage immediately to prevent it from escalating.
