As a roofing specialist with years of experience in the industry, I've seen a variety of roofing solutions, including the installation of rubber roofs over shingles. The process is quite intricate and requires careful consideration to ensure a long-lasting and effective roofing system.
Step 1: Assessing the Current Roof
The first step in installing a rubber roof over shingles is to assess the condition of the existing roof. This involves checking for any damage, rot, or other issues that might compromise the integrity of the new rubber roof. If the shingles are in poor condition, it may be necessary to remove them before proceeding.
Step 2: Preparing the Roof Deck
Once the condition of the shingles has been assessed, the next step is to prepare the roof deck. This typically involves removing the shingles and any underlayment to expose the roof deck. It's important to ensure that the roof deck is clean, dry, and free of any debris before proceeding.
**Step 3: Installing Plywood or OSB Decking**
As mentioned in the provided reference, you cannot install an EPDM rubber roof directly over asphalt, tar, shingles, or felt paper due to the oils present in these materials, which can cause problems for the EPDM. Therefore, it's necessary to install a new layer of plywood or oriented strand board (OSB) decking over the existing roof. This new layer provides a clean, stable surface for the rubber roof to be installed upon.
Step 4: Installing the EPDM Rubber Roof
With the new decking in place, the EPDM rubber roofing material can be installed. This involves unrolling the EPDM sheet over the decking and securing it in place. The edges of the EPDM are typically sealed with adhesive and fasteners to ensure a watertight seal. It's crucial to follow the manufacturer's instructions carefully during this process to ensure proper installation.
Step 5: Sealing and Finishing
After the EPDM sheet has been secured, the final step is to seal all the seams and edges. This is done using a specialized adhesive that is designed to bond with the EPDM material. Once the seams are sealed, the roof is inspected for any potential leaks or issues. If everything is in order, the rubber roof is considered complete.
Step 6: Maintenance and Inspection
Finally, it's important to regularly inspect and maintain the new rubber roof to ensure its longevity. This includes checking for any damage, wear, or potential leaks, and addressing these issues promptly.
In conclusion, while it is possible to install an EPDM rubber roof over shingles, it requires a careful and methodical approach. The process involves assessing the existing roof, preparing the roof deck, installing new decking, and then properly installing and sealing the EPDM material. Regular maintenance and inspection are also key to ensuring the durability and effectiveness of the rubber roof.
