Considerations Before Installing Rubber Roofing Over Shingles

While installing this roof has its benefits, several key considerations must be addressed:

  1. Shingle Condition: The existing shingles must be in relatively good condition for the roofing installation to be effective. If the shingles are severely damaged or curling, it may not provide a suitable substrate for the rubber roofing.
  2. Weight: Rubber roofing can add extra weight to your roof. It’s crucial to ensure that your roof structure can support the additional load. Consult a structural engineer or roofing professional to assess your roof’s capacity.
  3. Roof Inspection: Before installation, have your roof inspected by a professional to identify any underlying issues that may need repair or reinforcement. This step is essential for long-term roofing integrity.
  4. Permits and Regulations: Check with your local building authorities for any permits or regulations related to installing this roof. Regulations can vary by location, and it’s essential to ensure compliance.

The Installation Process

The installation process for rubber roofing over shingles involves several key steps:

  1. Cleaning and Preparation: The existing shingles must be thoroughly cleaned and prepared. Any loose or damaged shingles should be secured or replaced.
  2. Underlayment: A layer of roofing underlayment is installed over the shingles. This underlayment provides an additional moisture barrier and helps create a smooth surface for the rubber roofing.
  3. Rubber Roof Installation: The rubber roofing material is installed over the underlayment. It is typically adhered to the surface using an adhesive or mechanically fastened, depending on the specific product and manufacturer’s guidelines.
  4. Flashing and Edging: Flashing and edging are installed to ensure water-tightness and protection at vulnerable areas, such as roof penetrations, valleys, and eaves.
  5. Inspection: After installation, the roof should be thoroughly inspected to ensure all seams are sealed correctly, and there are no visible issues.
