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.
The 2015 blizzards have had a calamitous effect on housing over the winter, causing damage and destruction to many roofs. After several feet of snow, buildings across the country began to buckle under the added weight, prompting officials to encourage home owners to clear their roofs of snow. The record-breaking snow, ice and freezing temperatures wreaked havoc on homes with older roofs causing collapses and sagging.
We’re no experts on safety, but there are some practical guidelines to onsite job safety from Occupational Safety and Health Administration (OSHA). These standards for construction sites help to reduce the risk of injury. Always remember to check local safety requirements and ensure that your crew is properly trained.
When the builder came to us with complaints of telegraphing through his roof shingles they assumed it was edge swell and the fault lay with the roof sheathing. Most often, swollen edges and buckling panels are caused by common installation mistakes.
