Roll roofing is a cost-effective and relatively easy-to-install roofing material, making it a popular choice for sheds, small outbuildings, and certain low-slope roofs. However, whether you can use nails to secure roll roofing depends on the specific type of roll roofing material you are working with and the installation method. In this article, we will provide you with clear and concise guidance on nailing roll roofing.
Types of Roll Roofing
Roll roofing is available in various materials, with the most common options being:
-
Asphalt Roll Roofing: This is a self-adhesive material that comes with a peel-and-stick backing, eliminating the need for nails in most cases. It’s an easy and quick solution for flat or low-slope roofs.
-
Modified Bitumen Roll Roofing: This type is typically applied with heat or cold adhesive and may require nailing along the edges or overlaps for added security.
-
Rubber EPDM Roll Roofing: EPDM (Ethylene Propylene Diene Monomer) roofing is usually adhered with roofing adhesive and does not require nails for attachment.
Nailing Roll Roofing
If you are working with a roll roofing material that does not have a self-adhesive backing or requires additional securing, here are some key considerations for nailing roll roofing:
-
Nailing Pattern: When nails are necessary, they are typically used along the edges of the roll roofing material and at overlaps to prevent wind uplift and ensure proper sealing. The specific nailing pattern will vary depending on the manufacturer’s recommendations and local building codes.
-
Nail Type: Roofing nails with a large, flat head are usually recommended for roll roofing. These nails provide better holding power and weather resistance.
-
Spacing: Nail spacing will also be specified by the manufacturer. Common spacing is every 6 to 12 inches along the edges and overlaps.
-
Roof Deck: Ensure that you are nailing the roll roofing into a solid roof deck, such as plywood or OSB (Oriented Strand Board). The roof deck should be clean, dry, and in good condition to provide a secure base for the roofing material.
When Not to Use Nails
In some cases, it’s important to note that roll roofing is not designed for nail attachment. If you have self-adhesive roll roofing or are using a roofing adhesive, attempting to nail the material can compromise its integrity and effectiveness. It’s crucial to follow the manufacturer’s installation instructions to ensure the best performance and longevity of the roofing material.
Conclusion
In summary, whether you can nail roll roofing depends on the type of roll roofing material you’re working with and the manufacturer’s guidelines. It’s essential to follow the recommended nailing pattern, spacing, and nail type if your roll roofing requires nails for attachment. If you have self-adhesive roll roofing or are using roofing adhesive, nailing is not necessary and can even be detrimental to the roofing material’s performance. Always consult the manufacturer’s instructions and, if in doubt, seek advice from a roofing professional to ensure a secure and weather-resistant installation of your roll roofing.
