A Guide to Rolled Asphalt Roofing Installation

Rolled asphalt roofing is a popular choice among homeowners and contractors due to its affordability, durability, and ease of installation. This type of roofing is particularly suited for low-slope roofs and can provide reliable protection against the elements when installed correctly. In this article, we will guide you through the steps of rolled asphalt roofing installation, highlighting the tools and materials needed, as well as tips for achieving the best results.

Materials and Tools Required

Before beginning your installation, it is essential to gather all necessary materials and tools. The primary material you'll need is rolled asphalt roofing, which comes in large rolls. The thickness can vary, but 1/8 inch is common for residential applications. Other materials include

- Roofing felt - Asphalt roofing cement - Nails or roofing staples - Roofing primer (if required) - Flashing materials for edges and penetrations

The tools you might require include

- Utility knife - Chalking line - Measuring tape - Hammer or nail gun - Caulk gun (for roofing cement) - Ladder

Preparation

Before laying down your rolled asphalt roofing, proper preparation is key. First, inspect your roof structure for any damage. Ensure the surface is clean, dry, and free from debris. If your existing roof has damaged sections, replace or repair them to ensure a smooth installation.

Next, measure the area of your roof to determine how much rolled asphalt you will need. It is advisable to order a little extra material to accommodate mistakes and wastage.

Installation Steps

1. Apply Roofing Felt Start by laying down a layer of roofing felt over the roof deck. This provides an additional moisture barrier. Roll the felt out horizontally across the roof, overlapping each row by about 4 inches. Secure the felt with roofing nails or staples.

2. Cut the Rolled Asphalt Unroll the asphalt roofing, ensuring it is neatly laid out before cutting. Cut the roll to length, accounting for overhangs as necessary. A good rule is to allow for an overhang of about 1 inch at the eaves.

3. Lay the First Sheet Begin laying the first sheet of asphalt from the bottom edge of the roof. Align it carefully, ensuring it’s straight. Once positioned, secure it with asphalt roofing cement applied along the edge, followed by nails or staples.

4. Overlap Subsequent Sheets For the following rows, overlap the new roll over the previous sheet by approximately 6 inches. Apply roofing cement along the top edge of the bottom roll before placing the new roll down. Secure it in place using nails or staples as you go.

5. Seal the Joints After all sheets are installed, go back and seal the seams with a thick layer of roofing cement. This seals the joints and helps prevent water infiltration.

6. Finish the Edges Install flashing around any roof protrusions, such as vents or chimneys, to ensure they are watertight. Be sure to use roofing cement liberally at these areas.

7. Final Inspection Once installation is complete, inspect the roof for any gaps, loose edges, or other issues. Make necessary adjustments or repairs to ensure a secure and comprehensive installation.

Maintenance Tips

After installation, regular maintenance is crucial to extending the life of your rolled asphalt roof. Inspect the roof periodically for signs of wear, leaks, or damage, especially after severe weather. Clean the surface to remove debris and ensure proper drainage to prevent water pooling, which can lead to damage over time.

Conclusion

Rolled asphalt roofing offers an economical and effective solution for low-slope roofs. With the right materials, tools, and techniques, anyone can successfully install this type of roofing. By following the outlined steps and conducting regular maintenance, you can enjoy the benefits of a durable and weather-resistant roof for many years to come.
