Had workers show up at 6:00 a.m. on the roof at our rental duplex while we were sleeping still on a Tuesday morning. None of them spoke English when I had to go outside and tell them to get down because of a noise ordinance and we were still sleeping. Had the owner of the company blocked me in the driveway when I had to help him get his trailer out of the driveway because he couldn't get the trailer hooked up to his truck. I knew a storm was coming so I finished working on my friend's truck before the storm hit as I watched the roofers continue to work on the entire roof which was completely ripped off minus the little bit of wood that was left. As it started to downpour soaking and ruining all of our belongings and flooding our home. Only to see the roofers pack up and take off after leaving a used sad excuse for a tarp over the roof just barely over the sides as more storms are coming in and strong winds. Again the owner completely absent nowhere to be seen. Now it's 7:00 at night our homes ruined all of our belongings are ruined soaking wet our beds ruined we have holes in our ceiling.

We had our roof completely replaced a few years back by another company in town and they didn’t do the correct venting. After we realized we had issues this year we asked for it to be fixed and they wouldn’t do it. We called Sieren Roofing …

Great service ! I highly recommend this family owned business.This has leaked for years even new gutters, but Bob was able to come in there and fix it. Even the gutter messed up from another company. Great service. I haven’t had a drop of rain in there at all.
