What Is Rolled Roofing?

When it comes to roofing, there are a variety of materials to choose from, each with its unique advantages and disadvantages. Commercial rolled roofing, or mineral-surfaced roofing, is a popular option for low-slope roofs, including porches, sheds, and small outbuildings. It is made of asphalt and is relatively inexpensive and easy to install, making it a practical choice for many homeowners.

Composition of Rolled Roofing

Rolled roofing is made of the same materials as asphalt shingles but is thinner and comes in long rolls. The base layer is made of a fiberglass mat or felt, coated with asphalt and mineral granules to provide a durable, weather-resistant surface. The granules also give the roof its color and texture.

Advantages of Rolled Roofing

One of the biggest advantages of rolled roofing is its low cost. It is one of the most affordable roofing materials available, making it an attractive option for homeowners on a budget. It is also relatively easy to install, saving homeowners money on labor costs. Additionally, rolled roofing is lightweight and requires minimal maintenance, which can further reduce long-term costs.

Another advantage of rolled roofing is its versatility. It can be used on various low-slope roofs, including porches, sheds, and garages. It is also available in various colors and textures, allowing homeowners to choose the option that best fits their style and preferences.

Disadvantages of Rolled Roofing

While rolled roofing is a popular option for many homeowners, it has disadvantages. One of the most significant drawbacks is its durability. Rolled roofing is not as durable as other roofing materials, such as asphalt shingles or metal roofing. It has a relatively short lifespan and may need to be replaced more frequently than other types of roofing.

Another disadvantage of rolled roofing is its appearance. While it is available in various colors and textures, it may have a different visual appeal than other roofing materials. It also tends to fade over time, detracting from its appearance.

Installation Process

The installation process for rolled roofing is relatively simple, making it an ideal DIY project for homeowners with some roofing experience. The first step is to prepare the roof surface by removing any debris and ensuring it is clean and dry. Next, the roofing felt is rolled out over the roof’s surface and cut to size.

Once the felt is in place, the roofing material is rolled out over the felt and nailed down. The seams between each roll of roofing material are sealed with roofing cement to ensure a watertight seal. Finally, the edges of the roofing material are trimmed to fit the roof and sealed with roofing cement.

Rolled Roofing Installation

Rolled roofing is a popular and affordable option for low-slope roofs, including sheds, porches, and small outbuildings. While it is relatively easy to install, following the proper procedures to ensure a watertight and long-lasting roof is important. Here are the steps for rolled roofing installation:

Prepare the Roof Surface

The first step in rolled roofing installation is to prepare the roof surface. This involves removing debris from the roof’s surface, such as leaves, twigs, and dirt. It is also essential to ensure the roof surface is clean and dry before installing the roofing material. Any wet or damp areas should be allowed to dry completely before installation.

Install Roofing Felt

Once the roof surface is prepared, installing the roofing felt is next. Roofing felt, also known as underlayment, provides an additional layer of protection between the roof surface and the roofing material. It also helps to prevent water from seeping through the roof and damaging the underlying structure.

To install roofing felt, roll it out over the roof’s surface and cut it to size using a utility knife. It is essential to overlap the edges of the felt by a few inches to ensure a watertight seal. Secure the felt using roofing nails, spacing them about 12 inches apart along the edges and 6 inches apart in the middle.

Install Rolled Roofing

Once the roofing felt is in place, the next step is to install the rolled roofing material. Rolled roofing is available in long rolls that are typically 36 inches wide and 33 feet long. To install the roofing material, start at the lowest point of the roof and roll out the roofing material horizontally across the roof.

Overlap the edges of each roll of roofing material by about 6 inches to ensure a watertight seal. Secure the roofing material in place using roofing nails, spacing them about 6 inches apart along the edges and about 12 inches apart in the middle. Be sure to nail the roofing material into the decking, not just the roofing felt.

Seal the Seams

Once the roofing material is installed, the next step is to seal the seams. The seams between each roll of roofing material should be sealed with roofing cement. Apply the cement to the underside of the roofing material using a putty knife and press it firmly in place. Be sure to smooth out any wrinkles or air pockets to ensure a tight seal.

Trim the Edges

Finally, the edges of the roofing material should be trimmed to fit the roof. Use a utility knife to cut the roofing material to size, leaving about 1/8 inch of overhang on each edge. Be sure to trim the corners to create a neat, finished appearance.

Inspect and Maintain the Roof

Once the roofing material is installed, inspecting and maintaining the roof regularly is crucial. Inspect the roof periodically for signs of damage or wear, such as cracks, tears, or missing shingles. Repair any areas of damage promptly to prevent water from seeping through the roof and causing damage to the underlying structure.

Maintenance and Repair

One of the benefits of rolled roofing is that it requires minimal maintenance. However, it is important to inspect the roof periodically for signs of damage or wear. Any areas of damage should be repaired promptly to prevent water from seeping through the roof and causing damage to the underlying structure.

Common repairs for rolled roofing include patching holes or tears in the roofing material, replacing damaged or missing shingles, and sealing any areas where the roofing material has lifted or come loose. Homeowners should also keep their gutters clean to prevent water from backing up and causing damage to the roof.

Rolled roofing is a practical and affordable option for homeowners looking to install or repair a low-slope roof. While it has some disadvantages, such as its durability and appearance, it is popular for sheds, porches, and other small outbuildings. With proper installation and maintenance, rolled roofing can provide a watertight, weather-resistant surface for many years.
