I live in a 1958 home with tectum panel decking and some sort of roll roof on top of it. The panels of tectum that are inside are in perfect condition. However, many areas around the house where the roof "overhands" are badly damaged probably from water. Is there any way to solve this problem from the underside? Like with replacement tectum? Or do we have to tear off the top to get to the damaged areas then replace the roof over the decking?
Sorry if I sound clueless--it has taken us 6 months to even learn that it's called tectum panels! I have spoken with roughly 30 roofers, contractors and the like and no one has experience or any way to help. We live in rural southeast Missouri so not as many resources.
Thanks for any advice/info!
