We have a church that’s approximately 12 years old and started leaking within about a year. It has a corrugated metal roof installed with screws with rubber seals. My question to you is: other than replacing with a whole new roof is there any other options for us to do that would work to seal it and stop the leaks? Is there some type of spray on application that could be used that would cost less than a roof replacement?
Wow, that sound’s like a real mess! I suspect installation errors and suggest you have this looked at by a professional home inspector. You can find one by going to the website for the American Society of Home Inspectors. A home inspector will be able to evaluate the installation without trying to sell you a new roof and hopefully identify the core problem so that it can be repaired.
This has to be done soon, as all that moisture will lead to mold growth that can be very unhealthy, especially for kids in those classrooms.
