Replaced roof sheathing with old cracked osb. Had high and low nails on shingles. Did a poor job cleaning up. Wreaked my fasica boards. Only told me after the job was paid for that I should add more soffit vents. Only reason they get 2 stars is they gave me free warranty and came back to fix the osb and high nails in shingles. I think its only reasonable to expect a good job the first time around.
