The roof has sip panels. Not long after building we noticed our downspouts filled with granular crystals from the roof and the shingles were curling. We put the roof right on top of the panels with ice guard underneath. At home shows we started questioning roofers about our situation. We bit the bullet and installed a metal roof last year. When they were tearing off the shingles they saw evidence of the start of dry rot on our sip panels. They took pictures and showed us. We put in a cold roof system under the metal roof. If you have a sip roof or are putting one on, please research, research, research before applying the shingles directly on top of the sip panels with no venilation. Our metal roofer told us we were third homeowners with sip panel roof to contact him with this problem. One homeowners roof was 12 years old and in quite serious shape. Most sip panel manufacturers dance around this question of venting or not to vent. Please check this out throughly so you don't end up replacing a roof only 7 years old like we had to do to head off serious problems down the road.
