Commercial job...C-9s on their sales office, guard shack and Pavilion. Several places where the shingles are loose and the cord has come out and it's drooping. What's the best way to handle this? We had this happen one other time at a city gazebo...but was very small gazebo...convinced the City time to replace the roof (it was in horrible condition). Thanks for the help...love this Forum! And David -- love reading your posts --- we saw you at the HBL Convention.
