Installing Rolled Asphalt Roofing A Step-by-Step Guide

Rolled asphalt roofing is a popular choice for homeowners and builders because of its cost-effectiveness and ease of installation. This type of roofing is particularly suitable for flat or low-slope roofs, providing durability and protection against the elements. In this article, we’ll walk through the steps for installing rolled asphalt roofing, ensuring your roof is both functional and aesthetically pleasing.

Materials Needed

Before beginning the installation, gather all necessary materials. You will need rolled asphalt roofing (usually in 3-foot wide rolls), asphalt primer, roofing nails, a utility knife, a broom, a roller or brush for applying primer, a measuring tape, a chalk line, and safety equipment like gloves and goggles.

Preparation

The first step is to prepare the roof surface. Clear any debris, dirt, or loose materials to create a clean working area. If there are any punctures or significant wear on the old roofing, repair these areas. It’s essential that the surface is dry and free of damage to ensure proper adhesion.

Applying Primer

Once the surface is prepared, apply asphalt primer. Use a roller or brush to coat the entire area where the rolled roofing will be installed. The primer helps the asphalt bonds better to the roof surface, enhancing durability. Allow the primer to dry according to the manufacturer’s instructions, generally for about 30 minutes to an hour.

Measuring and Cutting

After the primer has dried, measure the length of the roof and cut the rolled asphalt to the appropriate size. It's important to leave a slight overlap between rolls, typically about 4 to 6 inches, to prevent water from seeping through seams. Use a utility knife for clean and straight cuts.

Laying the First Row

Start laying the first row of rolled asphalt at the lowest point of the roof. Position the roll so that it overhangs the edge slightly. Unroll the material and press it firmly onto the primed surface. As you unroll, use a broom or your hands to smooth out any air bubbles. This is crucial for ensuring a tight seal.

Nailing and Securing

Once the first row is in place, secure it with roofing nails, placing them at consistent intervals – typically every 12 inches. Make sure to nail the overlaps securely to prevent wind lift. Repeat this process for successive rows, keeping the necessary overlap and ensuring a consistent alignment with the first row.

Finishing Touches

After all rows are installed, check for any loose edges or seams. Apply additional primer and sealant as needed to ensure everything is watertight. Finally, trim any excess material for a clean finish.

Conclusion

Installing rolled asphalt roofing can be a manageable DIY project with the right preparation and care. By following these steps, you’ll create a durable and effective roofing solution that protects your home for years to come. Remember, safety should always be your priority; take care while working at heights and consider consulting a professional if the job feels daunting. Happy roofing!
