How to install roll roofing

Installing roll roofing is a straightforward process and can be a good option for sheds, garages, and low-slope roofs. Here’s a step-by-step guide:

Clean the Surface: Remove any debris, old roofing material, and dirt. Use a broom or leaf blower to ensure the surface is smooth.
Inspect the Roof Deck: Check for damaged or rotting sections of the roof deck and repair them before proceeding.
Apply Underlayment (Optional): Roll out roofing underlayment for added waterproofing. Secure it with roofing nails.

Measure the roof dimensions and cut the roll roofing into manageable lengths. Add a few extra inches for overlap at the edges.

Start at the lowest edge of the roof (eave) to ensure water flows over the layers.
Lay the first piece of roll roofing horizontally across the roof, allowing a 1-inch overhang over the edge.
Use a chalk line to ensure it is straight.

Nail the top edge of the roll roofing, spacing nails about 6 inches apart.
Apply roofing cement under the edges for extra sealing, especially in areas prone to high winds or water pooling.

For the next layer, overlap the previous strip by about 4 inches. This overlap ensures water doesn’t seep between the layers.
Secure the new layer with nails and roofing cement as before.

When you reach the peak of the roof or the final layer, trim the roll roofing to fit and secure it with nails and roofing cement.
Ensure all edges are sealed properly to prevent leaks.

Work on a Dry Day: Install roll roofing in dry weather with temperatures above 50°F for better adhesion.
Safety First: Use fall protection equipment and avoid working on steep slopes unless properly trained.
Maintenance: Check the roof periodically for damage or wear and reapply roofing cement as needed.

By following these steps, you can successfully install roll roofing, ensuring a durable and weather-resistant covering for your structure.
