We are about to wrap up spring planting and are starting to get some better weather to start our shop roof restructure and roofing.
Here is the big debate:
Screw in the flats or the ribs?
From the contractors I have asked, it is about 50/50. Morton screws in the ribs, but their metal is much thicker. The metal supplier/manufacturer says it doesn’t matter as far as warranty goes. Most metal roofing contractors say the screws need replaced every ten years.
There were NUMEROUS issues with the other roof that has caused it to fail. I have always screwed in the flats with a screw next to each rib and one extra on the last flat. I also screw each side of the ribs on the bottom run.
The current roof is too flat(2/12), the purlins are 1x6, the screws were over tightened, the lap is bass ackwards, and the transition from the 4/12 roof to the addition wasn’t done correctly. Also there is gable end flashing which has caused some water damage underneath. The original section is screwed in the flats into 2x6 rough cut poplar and only has a couple leaks. These are mainly screws/washers breaking down. It is over 25 years old.
Our plan is to set mono trusses on the addition and stick build to the ridge of the original shop. Then 2x6 roof purlins and metal.
Any metal roofers in here want to give me their two cents?
Thanks
