In this article, we will delve into the essentials of roll roofing, exploring its composition, benefits, and ideal applications, while also addressing some common questions that arise about this versatile roofing solution.

Roll roofing is a type of roofing material that comes in large rolls, making it easy to install and manage. Typically made from asphalt or modified bitumen, roll roofing is designed to provide a durable and weather-resistant barrier for flat or low-slope roofs. Its installation process is straightforward, often requiring fewer tools and less labor compared to traditional roofing materials, which can translate to significant cost savings for homeowners.

In addition to its affordability and ease of installation, roll roofing offers a variety of styles and colors, allowing for customization to fit different aesthetic preferences. However, it’s essential to understand the specific characteristics of roll roofing, including its lifespan, maintenance requirements, and suitability for various climates. As we explore these aspects further, you’ll

Composition of Roll Roofing

Roll roofing is primarily composed of asphalt and fiberglass, providing a durable and weather-resistant solution for low-slope roofs. The materials used in roll roofing can vary, but the most common types include:

  • Asphalt-impregnated felt: This is a traditional option, often used for residential roofs.
  • Fiberglass mat: Provides enhanced durability and resistance to tearing.
  • Mineral granules: These are often embedded in the surface to protect against UV rays and add aesthetic appeal.

The layers of roll roofing are typically bonded together, which enhances their structural integrity and performance.

Installation Process

The installation of roll roofing is relatively straightforward, making it a popular choice among contractors. The following steps outline the general process:

  1. Preparation of the Roof Deck: Ensure the surface is clean, dry, and free from debris. Any existing roofing material should be removed if it compromises the new installation.
  2. Laying Out the Roll: Unroll the roofing material on the roof deck, allowing for some overlap at the seams.
  3. Adhering the Material: Use roofing adhesive or nails to secure the roll in place. Make sure to fasten along the edges and seams to prevent water infiltration.
  4. Sealing the Seams: Apply roofing cement or a sealant to the seams to ensure a watertight seal.
  5. Finishing Touches: Install flashings and any required accessories, ensuring all edges are sealed.

Advantages of Roll Roofing

Roll roofing offers several advantages that make it a favorable choice for low-slope and flat roofs:

  • Cost-Effective: Generally less expensive than traditional shingles or tiles.
  • Quick Installation: The installation process is faster due to the large rolls, reducing labor costs.
  • Durability: Provides good resistance to weather elements, especially in moderate climates.
  • Low Maintenance: Requires less maintenance compared to other roofing materials.

Disadvantages of Roll Roofing

While roll roofing has its benefits, there are also some drawbacks to consider:

  • Limited Lifespan: Typically lasts 10 to 20 years, which is shorter than other roofing options.
  • Aesthetic Limitations: May not provide the same visual appeal as shingles or tiles.
  • Susceptibility to Damage: Can be more prone to punctures or tears compared to sturdier materials.

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
