So, what is roll roofing? Also known as rolled roofing, this material is an MSR (mineral-surfaced roofing product) commonly used in various roofing systems. It’s an oil-based asphalt product that’s easy to install, making it a popular choice for both sloped roofs and flat roofs.

The material comes in rolls with 100 square feet, or about one composite shingle square if you compare it in terms of quantity. It is considered the cheaper solution to asphalt shingles with similar qualities, although decidedly thinner and less durable.

In general, the lifespan of roll roofing can be anywhere from 6 to 10 years. Some high-quality ones can last for 15 years. You can see that the average life is shorter than conventional roofing material.

Sometimes, people use it in companion of conventional shingles as well, by using it as the base material underneath in commercial constructions.

This material is a less popular option for residences because it has a chance for future leaks. This unfortunate reason exists because a series of nails are used to attach roll roofing, and each nail has the opportunity to present leaks.

Roll roofing cost is also a factor determining its lifespan – as quality typically comes with the cost. Here are the estimations of cost if you’re interested in installing them:

  1. The material itself costs about $30 to $100 for each square foot. Multiply the material cost by your roof size to find the total material cost.
  2. The installation costs about $1.50 to $3 for each square foot. Multiply the installation cost by your roof size to find the total installation cost.
  3. If you already have an existing roof, the removing and disposing jobs cost about $1 to $2 for each square foot. Multiply the removal and disposal costs by your roof size to find the total installation cost of them.

Once you understand what roll roofing is, it’s important to consider its ease of installation. Roll roofing, including common types like roofing felt and modified bitumen, is known for being easy to apply, especially on types of roofs with low slopes.

Peel-and-stick, or self-adhesive, is one of the many types of rolled roofing materials. Self-adhesive rolled roofing is an option that has the benefit of faster installation time.

Here are the steps to install it:

  1. Clean the roof deck from debris by sweeping it. To clean ingrained oil marks and dirt, use a degreaser. Then, wipe with a damp cloth to remove the remaining dust.
  2. To make sure you have a smooth surface, hit raised nail heads to the roof deck. Read the manufacturer’s instructions first to decide if you need asphalt primer or not.
  3. Line up the length of rolled roofing with the lowest side of your roof. Put the roofing sheet’s edge accurately and smooth it down to adhere it to the roof deck.
  4. Peel the sheet back and smooth it down to prevent wrinkles. Cut the size using scissors or a utility knife. Then, firmly press the length using a hand roller to the roof deck.
  5. To create a watertight layer, you can layer each previous course by three inches. Then layer the end piece of the roll by 6 inches between the courses.

Understanding the different types of roll roofing is crucial for selecting the right material for your project. For instance, modified bitumen is a popular choice for its durability and ease of repair, while traditional oil-based asphalt products are valued for their cost-effectiveness.

Now, you know what roll roofing is and the information about it. You have to check if your roof is suitable to install. Roll roofing is particularly well-suited for low-sloped roofs due to its flatness and flexibility. This characteristic simplifies the installation process, allowing for a smooth application of roll roofing even by those with limited experience.
