Guide to Installing Rolled Asphalt Roofing for Optimal Performance and Durability

A Comprehensive Guide to Rolled Asphalt Roofing Installation

Rolled asphalt roofing is an economical and practical solution widely used for low-slope or flat roofs. Known for its ease of installation and durability, it is a favorite among homeowners and contractors alike. This article will guide you through the essential steps to successfully install rolled asphalt roofing, ensuring a long-lasting, weather-resistant surface for your building.

Materials and Tools Required

Before starting the installation process, gather all necessary materials and tools. You will need rolled asphalt roofing material (usually in 36-inch wide rolls), roofing felt, asphalt cement, nails, and a utility knife. Additionally, basic tools such as a hammer, a paint roller or brush (for the asphalt cement), a measuring tape, and a ladder are also essential.

Preparing the Roof Surface

The first step in the installation process is to prepare the roof surface. Ensure that the roof is clean, dry, and free of debris. If there are any existing roofing materials, they might need to be removed. Inspect for any damages, such as holes or cracks in the decking, and repair them accordingly. A smooth, even surface is crucial for the successful application of rolled asphalt roofing.

Installing the Underlayment

Once the roof surface is prepared, the next step is to install a layer of roofing felt or underlayment. Begin at the lowest edge of the roof and unroll the felt horizontally across the roof. Use a staple gun or roofing nails to secure the felt in place, overlapping each row by about 2-4 inches to ensure proper coverage. This layer acts as a moisture barrier and adds an additional layer of protection for your roof.

Applying the Rolled Asphalt Roofing

With the underlayment in place, it’s time to start installing the rolled asphalt roofing. Begin by unrolling the first strip at the edge of the roof, ensuring that it hangs over the edge slightly (approximately 1 inch) to allow for water runoff. Use asphalt cement to adhere the strip down, and secure it with nails every 12 inches along the edges and in the field (the area between the edges).

Continue this process with subsequent rolls, overlapping each previous strip by about 2-4 inches. This overlap is crucial for preventing water infiltration. When you reach the ridge of the roof, cut the final strip to fit, ensuring it is securely fastened.

Sealing and Finishing Touches

Once all rolls are in place, it’s essential to seal the seams to prevent leaks. Use a paint roller or brush to apply a layer of asphalt cement over the seams, ensuring full coverage. Pay special attention to the edges around chimneys, vents, and other protrusions, as these areas are particularly vulnerable to leaks.

Finally, inspect your work to ensure everything is secure, and make any necessary adjustments. Cleaning up the work area is also essential to avoid leaving behind debris that could potentially damage the new roof.

Conclusion

Installing rolled asphalt roofing is a straightforward process that can provide sturdy and weather-resistant protection for your structure. With proper preparation, attention to detail, and the right materials, you can achieve a professional-looking roof that stands the test of time. Whether you are a seasoned contractor or a DIY enthusiast, this installation guide will help you navigate the process efficiently.
