After 20+ years my tile roof underlayment was giving out - I started noticing a few spots here and there.
I got three bids (German, Porter, and someone forgettable). I found German through my cousin who used them to do his roof a year ago. I honestly thought Porter was going to get the job but they totally overbid the job.
German came out when scheduled and removed all of the tile, underlayment, and damaged wood. They put two layers of underlayment on the roof and put the tiles back on. I wrote into the contract that they'd paint the new wood and the bird stops and the crew wasn't happy to learn that (from me) on the last day. But, there it was in black and white. They finished the whole job in a week.
The boss came out the following week to inspect the work and found a few spots that needed more sealant. Bear in mind that I never would have seen those spots so he could have easily blown it off. I appreciated his honesty.
About a month after the roof job I noticed some peeling paint in an overhang. I called and someone came out to inspect the area. We both concluded that it was most likely damage from before the underlayment was replaced but he did over to peel back the tile and make sure everything was OK in that area. Again, professional attitude. I scraped and repainted that area and we were right - must have been an old problem.
For the most part they were clean, professional, and efficient. They treated my property with respect. We did find a nail here and there for a week after the job was done but I suppose that's to be expected.
I would use them again.
