When replacing a rubber roof, remove the existing roof in warm weather when the glue that holds the roof is pliable and soft. Always contact the local building code enforcement agency for the necessary building permits before undertaking a roof replacement, and have all necessary supplies before starting the project.
Rubber roofs are generally easier to repair and replace than traditional roofs. However, the materials needed for the job can be as much as four times the cost of asphalt roofs. If cost is an issue, repair only the damaged parts of the roof to save money.
When replacing a rubber roof, cut the old rubber into smaller, more manageable pieces to make working with it easier. After the old roof is gone, the new roof can be installed in much the same way as the original roof. Add a layer of foam to the top of the roof to provide insulation.
Before undertaking the task of replacing the roof, contact a contractor to receive an estimate for the work. Sometimes it is better to let a professional handle roofing if it fits in the budget. Compare the estimate to the cost of do-it-yourself repair, and determine which process is better.
Always work with a rubber roof during dry weather. Do not use nails or screws on a rubber roof to avoid puncturing the material. If moisture penetrates the roof, it will have to be replaced.
