Causes of Telegraphing through Roof Shingles: It’s not Always the Obvious!
Recently we had a call from a builder complaining that their roof sheathing was buckling, causing a telegraphing effect through their roofing shingles. Concerned about the structural efficacy of the roof, they asked us to take a look. The builder and dealer thought it was a number of problems with the roofing panels themselves but, on closer inspection, we discovered that there were a number of installation issues that caused the problem.
