Rolling Roofing Over Existing Shingles A Practical Guide

Rolling roofing over existing shingles is an effective and cost-efficient solution for homeowners looking to upgrade their roofing without the hassle of a complete tear-off. This method not only saves time and labor costs but also minimizes the amount of waste produced, making it an environmentally friendly choice.

Before embarking on this project, it’s essential to assess the current state of your existing roof. Ensure that the shingles are in good condition — free from significant damage, curls, or extensive wear. If your roof has only minor issues, such as a few broken or missing shingles, repairs should be addressed prior to installing the new roofing layer. It’s also important to check for any underlying leaks or structural problems that could affect the new roofing material's performance.

Once you've confirmed that your existing shingles are suitable for a new layer, gather the necessary materials. Rolling roofing, typically made from modified bitumen, is designed for ease of installation and durability. It often comes in large rolls, making it convenient to cover large areas quickly. You will also need roofing cement, a utility knife, a roller, and safety equipment.

The installation process begins with thoroughly cleaning the roof surface to ensure proper adhesion. Remove any debris and old materials that could hinder the bonding of the new layer. After the preparation, roll out the new roofing, allowing for overlaps as specified by the manufacturer—usually around four inches. For added security, apply roofing cement or adhesive beneath the rolls to prevent water infiltration and ensure a strong bond.

It’s advisable to work on a dry, sunny day to promote quicker adhesion and drying. As you lay down the roofing, use a roller to press it firmly against the shingles beneath, removing any air bubbles. Work in sections, overlapping the edges as you go, until the entire area is covered.

After the installation is complete, inspect your work for any gaps or areas that need additional sealing. This will help extend the life of your new roofing and keep your home protected from the elements.

In conclusion, rolling roofing over existing shingles is a practical choice that can save time and costs while providing reliable protection. With careful preparation and installation, you can achieve a durable and long-lasting roof. Always consider consulting a professional if you're unsure about the process or require assistance.
