Excellent company to work with, can be counted on to fix problems. We gave them a difficult assignment, a complex leak in a tough spot below a balcony adjacent to our garage roof. So a flat area above essentially a low slope funnel covered in metal shingles, concentrating water into an awkward spot below the balcony. Multiple possible sources of the leak. This took several experiments with a hose and water to finally isolate. They also encountered a glitch with material that needed extensive rework of the balcony floor, but the company stood by their original quote and persevered. Kudos to the team at Principal, for exceptional experience in this type of problem solving, obvious commitment to quality, excellent communication throughout, and ability to get things done!
