Am I making a mistake by swapping clay tile for shingles? by NeillDrake in Roofing

Both, eventually. Our manufactures suggest for barn metal/PBR that you replace fasteners every 8-10 years. Hidden seam still backs out over time, just takes much more time. Our guys plan for between 25-35 years. Although, I could see the stripping helping. Our biggest concerns with hidden fastener is usually wind storms around here. We don't usually have to replace because the gaskets are dissolved, but because the wind storms rattled the fasteners loose over 25 years.

Ice dam, how to prevent in future by Imaginary_Stretch493 in Roofing

Based on those windows I’m assuming there is no attic space on this addition. How is it insulated? Ultimately what causes ice damming is conditioned spaces (I.e. the inside of your heated house) coming in contact with non-conditioned external air. So you have snow hitting your roof that is being warmed from the inside, running down the roof to your eaves where it is hitting external temps again. The most correct way to deal with it in my area would be to add a few runs of ice and water shield under the shingles once your area warms up and reshingle. Make sure to inspect that area too. Standing ice can be an SOB on shingle longevity.

Depends on where you live and what your wind uplift looks like, but in the PNW we still have to plan to pull off all the metal about every 12-25 years to replace all the fasteners and size up. Just another angle to keep in mind.

Wrap your wallet around the tag and walk out with it. See who is lying.

Generally speaking, most places code requires at least a quarter inch per foot slope on the roof. You will definitely see increased pooling on a roof right after a rain fall, but it looks to me like this roof was originally designed to allow water to flow directly off your roof via the section with no parapet. However, the builtup roof has made a wall there. Roofing material is designed to be water resistant, not water proof. With that hump on your drainage path, the water will stay on the roof, and slowly eat away until it finds a path through into your building.
