First, Bob & Joni were great to work with. Bob sat down with me to talk about the options I had. He's the only contractor that looked in my attic and suggested replacing my 10+ year old skylight. Great with the details. There was no pressure and was easy to talk to. Quality workmanship by his crew. I had 2 layers of roof torn off and roof replacement. They did an excellent job of protecting my shrubs and clean up. I can't believe I just found 2 nails (which were hidden). They did a thorough sweep of the yard to pick up debris. Joni was great with the communications and dropping off the gutter guard sample. Bob monitored the work through out the install. I highly recommend Sieren Roofing

Bob Sieren and crew were awesome. From expediently getting me a quote to roofing my house and garage, it was done quickly and professionally. They kept me informed every step of the way. I got the quote on Thursday and because the weather cooperated my roof was completed on Monday. Roofed my garage the next day on Christmas Eve. They covered my deck and shrubs and cleaned anything else up. No nails on alley or drive. Score!!! No worries going into winter with my new roof installed by Sieren's. PS. Who knew you could get a roof done in winter!! Thanks!

The workers removed all the old shingles and deposited the debris in a dumpster. No shingles or nails in the yard. New architectural shingles were installed with ice dam material in one day. Counterflashing was needed in several locations. All work was done from start to final cleanup in a day and half including sealing of the counterflashing. Workers were polite and diligent.

Bob and Sieren roofing repaired a leaking gutter on a flat roof that a previous replacement liner and repair failed to correct. There was heavy rain the day after the repair was made and the gutter worked perfectly, not one drop of water leaked through. The other gutter we had him work on needed to be replaced after a tree limb damaged it. He found the perfect color match, which can be difficult due to the original being 10 years old. I highly recommend Sieren roofing, their work is excellent and performed in a timely manner, plus he’s a really nice guy.

We meticulously sealed the gap, preventing any future leaks and safeguarding the integrity of the property.

We’ve had an ongoing issue with heavy rains where the water was going down our garage roof, and then in between a small gap between our siding and gutters…and then right down the side of the house. The original roof and siding installers caused the issue, but didn’t fix it, and most of the other roofing contractors I contacted didn’t want to bother with a small repair. Bob not only came out and assessed the issue, he came out again when the first fix didn’t take, figured out an alternative solution, and made additional changes to stop the problem. I never get that level of service from anyone anymore. When others just want to get the job done, Bob took the time to make sure the problem was fixed, and I really appreciated that. It may have been a small repair for Sieren Roofing, but I will absolutely be recommending them to anyone that asks me for roofing recommendations!

If I could give Bob and his company Sieren Roofing more than 5 stars, I would. He replaced our house and garage roof, replaced some gutters and even went out of his way to help us with some smaller jobs that other companies wouldn't come out to do because they were too small. Thanks to Bob we have new roofs with quality shingles, and he even recommended a ridge vent for ventilation which already is keeping our house cooler. He did everything professionally and alot quicker than I expected, and all at a fair price. We can't thank you enough Bob and we will continue to recommend you to all our family and friends.

Bob is your go to guy if you want the job done right. Nowadays these are hard to find! Also He took the extra mile helping me out with my insurance company settlement, without his help in verification on some matters I would have lost over a thousand dollars!

Would hire him again in a minute, he goes the extra mile for his customers!
