I reached out Sierra Exteriors on a Sunday and Max arrived the next day to give us a quote. He was very helpful and had clear, quick communication. He walked me through every step of the process so there were no surprises and even helped me go through our insurance which can often be a confusing, lengthy process. This process started June 23rd and we had a new roof on July 14th. I highly recommend Sierra Exteriors!

Sierra Exteriors was awesome to work with. They did a fantastic job on the roof and gutters on my new house. You are not going to find better value, efficiency, or quality work elsewhere. Colin was extremely helpful and a great communicator throughout the entire process. Their office made what I thought would be a difficult financing process very easy and worry-free. I would HIGHLY recommend Sierra Exteriors for your next roofing project, and I cannot say enough great things about my experience with them!

Fantastic crew to work with!! After several attempts to work with other companies it was so refreshing to find a company like Sierra Exteriors that understands how to work with customers to ensure they get what they pay for. Super fast install..... all new siding, new roofs, new gutters all on both our house and one out building, plus some new construction over our deck on top of everything, and it was all done in less than a week! Professional crew, great clean up everyday, and super accommodating. I would highly recommend these guys and will absolutely be reaching out to them for any future projects we decide to do.

Sierra Exteriors provided an exceptional experience. Maria and her team were highly responsive, ensuring that our siding project was completed on schedule with outstanding craftsmanship.

Our house needed serious updating. It turned out to have several flaws in the initial craftsmanship. They were very good at correcting the flaws and giving us an excellent looking siding job!

We had had it with birds creating holes in our cedar siding. Sierra came out and helped us make our home maintenance free and beautiful. They were professional and communicated with us every step of the way!

We couldn’t be happier with the incredible job done on our home by Sierra Exteriors, LLC. We used James Hardie siding and the installed it perfectly. From start to finish, the team was professional, detail-oriented, and genuinely cared about bringing our vision to life.

The quality of the work looks absolutely beautiful and we feel confident knowing we’ve invested in something durable, low-maintenance, and built to withstand the elements. The craftsmanship was top-notch, and the attention to detail by Sierra Exteriors in every corner and trim is truly impressive.

We’ve received so many compliments from neighbors and friends, and it honestly feels like we’re living in a brand new home. If you’re thinking about new siding, we wholeheartedly recommend going with Sierra Exteriors crew that brought our project to life. Thank you for making our home look amazing!

We totally recommend Sierra Exteriors for a new roof! They were great right from the start, with contacting the insurance company to making things happen! Our insurance unfortunately denied us, but we still ended up with a new roof because of their “Free roofs for Veterans” program that they just started. We want to thank them for giving back to Veterans and for not giving up on us ❤️
They got the roof done in less than one day and had everything cleaned up perfectly. Maria was great with communicating through the whole process and everyone was so nice.
You can’t go wrong going with Sierra Exteriors!!

I called Sierra Exteriors on Thursday explaining my damaged siding issue. They came out that afternoon to give me an estimate. They finished the work the next day, Friday! I am so happy with this entire process! They did great work along with great customer service!

I am very pleased with the work done by sierra. Maria would keep me apprised about the schedule so the work ran smoothly and to top it off my house looks new even though it just turned 100 last year.

Sierra Exteriors did a really nice job replacing a long strip of fascia along the peaked side of our roof. They were quick to reply to my inquiry about the job, they offered a very fair price, and completed the job shortly thereafter. I would definitely work with them again.

Sierra Exteriors was great to work with and did a beautiful job on our home. We had a big project for them as we did windows, siding, roof and doors and they confidently handled all of it. The good communication is what stood out to me and ultimately what led us to choose to work with Sierra Exteriors. They always responded and reached out to us, were there when they said they were going to be there, worked sunrise to sundown, and were always accommodating to any additional requests we came up with during the project. They also were very transparent with us on costs and offered alternatives if more affordable options were available. Highly recommend!

Needed to reside my 100 year old rental. Sierra came in half the price of the next bid. The crew did an awesome job! They were professional, fast, and clean. I would gladly recommend them to anyone.

Sierra Exteriors LLC were fantastic to work with! We heard of the company through our neighbor, and we are so glad we did! Maria made the process essentially seamless- bringing over samples that we were interested in, coming back with quotes, and fast replies/phone calls, even fitting us into the crew schedule sooner than expected. She did a throughout job with expectations and recommendations! The crew was fast and effective, getting it all done in a single morning/early afternoon (from dropping off supplies to clean up). We are so glad we went with Sierra Exteriors LLC and would recommend to anyone!

Great service! They installed a gutter on our pole building and it looks fantastic! They cleaned up afterwards and did not even disturb the flower bed underneath! Will definitely call them again.

Service was friendly and prompt. With a variety of roofing and gutter options, choices were well presented. As we moved through the purchasing process, pricing was clear. Any questions that we had, were addressed in a timely manner. We are extremely happy with our new roof and gutters, and highly recommend Sierra Exteriors!

Wonderful company! They were kind and took their time to explain everything. We had to make a claim through our insurance and they literally called with us to make sure we understood the process. As a first time homeowners, we appreciated the patience and detailed explanation of costs, etc. Our roof turned out beautiful and will be calling them again in the future for any new home issues!

I was shopping, an a lady dropped her gatorade. I helped pick it up an carries it to the check outs. She was a worker from Sierra. I checked out an walked out with her. Due to the storms in our area, there was lots of damage an work being done to the entire city. I asked if they could come look at my house. 2 hours later they were there. Assessed the damage, an took the pics an write up to there main office. 2 days later they came back out, with the manager- Maria, took more pictures, an called my insurance, sent them a report an pictures. My insurance agreed to the damage an paid out for the damage. Sierra, within 2 weeks we're here, fixed the damage. The roofers, very kind an responsive. Thank you, for a great job. My mother in law who originally hired another company, cancelled them, an went with Sierra

South Milwaukee, WI was hit by hail storm last May 7 2024. I was informed that my roof, gutters and siding were damaged. They helped me to file a claim to my insurance
Their crew did an excellent job, now my house looks a lot better than it was built 1983 with many selections of colors that match the roof, gutters and siding. Although my insurance only covers the affected side of the siding they gave me very reasonable price to replace the whole siding of my house.
Thank you Sierra. I’m very satisfied. Good job

If there was 10 stars it would be 11. From start to finish the experience was awesome. You’ll get communication every step of the way, Maria is the best. If you want 1, or 10 samples, they will get you them. The whole crew is very professional and polite. The team showed up promptly at 6am and was working by 6:02am, which we approved, due to high heat coming later in the day. They will however, work with what time works with you. We couldn’t be happier with the results.

We suffered severe hail damage May 7, 2024. Sierra Exteriors went above and beyond our expectations to document all of the damage we incurred. They gave our insurance company a very detailed report when giving us a free estimate. They worked very well with our insurance company to get the funds to complete the work. They replaced our roof, facia, gutters, downspouts and all of our exterior siding. They even replaced our shed roof and added a drip edge that we did not have previously. They used Owens Corning Shingles and we went from aluminum siding to James Hardy Plank siding. The workmanship was excellent!!!! All of their staff was very qualified and friendly. They were always available to answer our questions through out the process. Our 33 year old house looks like a new build now. They did a double tear-off and shingled our home in one day. The siding application was top notch!! Not a day goes by that someone in our neighborhood doesn't stop by and say what a beautiful house!! Who did your work? We proudly say SIERRA EXPERIORS !!!
Thank you so much!!! Lynn and Jason

The whole process was very easy with great communication and support. The roof looks great and everything was cleaned so well around the house afterwards. Would recommend Sierra Exteriors.

I can’t say enough about this company and the team they have. They approached me about the hail damage in my area and gave me a free estimate. When my insurance company came out Max hopped right on the roof with him…..Max even took the leaf blower to get all the leaves and debris off so nothing was missed to get approval from my insurance. 7 hours to tear off 3 layers of old shingles prep the roofs for barrier and lay the new shingles! My new roofs look stunning with the new gutters and fascia’s! Best in class. Thanks guys!!!

Sierra Exteriors did a wonderful job of replacing my parents roof and gutters following a bad hail store in their area. Maria was extremely helpful in walking us through every step of the process and working with insurance to get our claim processed quickly. The crew worked quickly and did a great job of cleaning everything up following the repairs.

Maria was very helpful in navigating the insurance claims process- going above and beyond to advocate on our behalf. The crew of workers did an excellent job, working hard and creating a high quality finished product. We have a tall house with nooks and protrusions that are challenging to navigate and they did a great job.

We had our roof re-shingled by Sierra Exteriors LLC earlier this month and couldn’t have been more satisfied. Maria (one of the owners) oversaw the entire project, from initial inspection right through to being on site for the installation. Maria was a pleasure to work with and genuinely cares about getting the job done right. She is well-informed about the business, explained all aspects of the process and was very responsive to all our questions/concerns. Quality service matched with reasonable prices makes it a great local business that we whole-heartedly recommend.

Sierra replaced my roof on March 28, 2024. They did an excellent job and were quite efficient. They were very conscientious about cleaning up. Maria coordinated and was constantly available. She did an excellent job of communicating and kept me updated at every turn. The work looks very good. Thank you Sierra!

I would like to thank the Sierra Exteriors workers and Maria for a job well done. The roof work and cleanup was done very professionally and it was done in one day. Maria did all the work dealing with the insurance adjuster over the hail damage estimate. I highly recommend Sierra Exteriors LLC

María was incredibly helpful in guiding me through the process of filing an insurance claim and coordinating the replacement of my roof. The Sierra crew arrived promptly on the agreed-upon day and took the time to cover items to prevent damage from debris during the tear-off process. María kept me updated throughout the entire process until the job was completed. Overall, I am very satisfied with the speed and appearance of my new roof.

There was a big hailstorm. It damaged everything. I'd never had extreme weather damage to a house. I didn't know what to do, and everything seemed so expensive, even with insurance. Folks at Sierra helped me navigate the insurance process, and even navigate what to do with other contracting companies while I was considering and getting estimates. They worked quickly, and they worked to our advantage. My whole neighborhood got hit by the hailstorm and I may have had the first new roof on my block. They gave me beautiful options to work with across a budgetary range. Not only did they show up on time and do what they said they were going to do, but when I told them I wanted warning that they would be on our property (I'm from the country and don't like surprises), they made sure to give it, and I was never surprised by guests or loud noises. When the weather was too bad for work in the winter, they gave me scheduling updates to the best of their ability. They care about doing what's right for your house, and they notice the little things. There was once a deck on my house, and we'd taken it off, and there was some of the house showing under where that siding had been once. We'd had to cover it up with expanding foam. It's all covered up and new looking now, no mice or plants or rain to worry about getting in. Right after they redid our gutters, an ice storm came and the ice fell from the roof and bent one of the downspout hinge-kicker things in half. They noticed and unbent it. When they took some of the cable and phone connections off the back of the house to redo the siding, they paid attention to what was current and needed, and put things back in place safely and carefully. Maria deserves a special shout-out for doing such good communications with me, day-in and day-out. She cared about how I felt. She even noticed what kind of person I am - I don't like advertising. Unlike other contractors, she asked permission before putting up a yard sign. I'd said no at the time, but I might reconsider my stance, because Sierra Exteriors is honest, too. When they had extra materials from siding the house and it looked like maybe they could put some of that siding on the garage, they told us about the idea right away, and it saved us money, and fewer materials were wasted, and the project was completed sooner! Our house, roof, and garage look amazing now. I feel like it could be in a painting, or a magazine, or it could go on the market, if we wanted, but it's so beautiful now and we get to live here. I'm wary about working with contractors, but I trust Sierra Exteriors.

Maria came to my door and asked if I was interested in looking into filing an insurance claim for a new roof, due to a terrible hail storm we had a few months prior. I knew my roof only had a few good years left so this was perfect timing! Maria and her team took pictures and worked with my insurance to get everything filed and approved and processed quickly. For me, it was a breeze...they did it all! We chose the colors and the crew finished my roof, lickety-split. and I must say, it looks AMAZING. They did they exact same for my aunt and she is just as thrilled about her new roof. I was so impressed with the entire experience we both had, I HAD to Sierra Exteriors replace my gutters and gutter/leaf guards. Maria is so sweet and kind and professional. Her crew was delightful. Beautiful work - I feel like I have a new house. Sierra Exteriors is the way to go!!
