For roof rivet leakage: If the rivets on the mobile home’s roof are leaking, first apply waterproof sealant four times, ensuring each layer dries evenly.​

For roof joint leakage: For the joints of the mobile home’s roof, start by filling the gaps with a seam sealer and applying sealant. Then, brush waterproof sealant at both ends of the joint, and adhere non-woven fabric or fiberglass cloth onto the wet sealant. Finally, apply the waterproof sealant three more times over the cloth.​

For small seam repairs: To fix small seams, paint the joints with special color waterproof plastic for steel structures, apply non-woven fabric paste, and then brush over the non-woven fabric.​

For larger seam repairs: When dealing with larger seams, fill them with a polymer flexible waterproof coating. Next, brush on special waterproof sealant, stick non-woven fabric firmly, and repeat the brushing process as described above.
