Even still, gravity flashings seem attractive in shingle roofs, to provide a second level of security, and a more professional install (at least in perception). But the cost of these systems in significant in high snow load areas where we often have L-feet every 2 feet on center, to evenly load the structure below. In todays costs, the feet could cost as much as 33% of the panel value.</div><div><br></div><div>I'm wondering what other people are doing in high snow load areas?</div><div><br></div><div>Also. I have noticed that there is a flip side to the risks. We have found that unless you have good quality shingles, on a preexisting roof, that sometimes the adhesive sticking the shingles together is stronger than the low quality shingles themselves - adding risk of trying to shoe horn flashing in after the fact. Your experience?</div><br><div apple-content-edited="true">
