Gutter Installation Across the Greater Denver Area
We fit seamless gutters and downspouts on new builds, replacements and storm claims across the Greater Denver Area. We size the system to the roof that drains into it, work out where the water has to end up, and quote it free.
What a Roofing Company Sees

Everyone who comes into your home is background checked. That's not something we arrange for one job. We also carry general liability and workers compensation insurance, so the risk sits with us, not you. Some of our salespeople speak Spanish too. Mention it when you reach out and we'll try to line one up, though that's availability, not a guarantee.
We've got about twenty years of hands-on roofing experience behind this work. Gutters are the bottom edge of a roof, which is the part of a house we've worked on longest. We look at the roof edge, the drip edge, the fascia and the gutter as one thing. Water that gets behind a gutter isn't a gutter problem at all. A crew that only knows gutters chases it in the wrong place. While we're up there, we look at the rest of the outside too. The storm that dented the gutters hit everything else on its way past.
Gutters Sized for the Roof Above Them

We size a gutter to the roof that drains into it, not off a shelf. Most gutters that overflow here aren't broken. They were never big enough, or never had enough downspouts, for the roof above them.
- Full replacement, first-time gutters, new construction, or gutters fitted alongside a new roof, so the drip edge and fascia are opened once, not twice.
- Five inch handles most roofs. Six inch earns its place on a large roof area, a steep pitch, valleys draining into one section, or a run limited to one outlet. A larger gutter is heavier, and the fascia has to carry it.
- Downspouts decide capacity as much as the gutter does. A long run needs more than one outlet, and the water has to land somewhere useful, clear of the foundation and off a walkway or a neighbor's yard.
The inspection and the estimate are both free.

What Makes a Gutter System Last Here
Two gutter systems can look identical from the street and behave completely differently under hail or a load of ice. The differences that matter here never show up on a quote.
- Seamless, formed on site from a coil, removes the joints down the run, where sectional gutter usually starts dripping. Corners, end caps and outlets are where a seamless system leaks if it leaks.
- Metal thickness matters in hail country. Thin builder-grade aluminum dents under thousands of hail hits in a few minutes; thicker metal survives ladders and ice loading better.
- Hanger spacing and pitch hold the system up in January. Closer spacing carries more weight, and every run should fall toward an outlet, since standing water freezes, expands and works everything loose.
- Gutter guards cut down how often a gutter needs clearing; they don't end it. We fit guards as part of a replacement and will tell you straight whether they'd earn their place.

What Our Customers Say
Adam Mayka
Josh with Semper Fi came to look at my roof after the most recent hail storm and couldn’t have been nicer. He was honest, thorough, and explained everything about the inspection process in great detail. His attention to detail and communication made it a very comfortable experience. Albeit we don’t need a new roof, when that time does come I will be using Semper Fi and I will recommend them to all of my friends and neighbors
Todd Reynolds
Was very responsive. I was able to get what was needed in regards to our roof inspections on three houses quickly. And worked with our insurance agent getting the right information needed for our insurance needs. If you’re looking for someone that knows roofs and you need inspections or confirmations regarding your roof. Highly would recommend recommend this company
Zilvinas Sutkus
We had Semper Fi Restoration Inc. complete the roof on our 10,000 sq. ft. commercial building, and we had a great experience from start to finish. We had the opportunity to meet Joshua Bosley and worked mainly with Leo, our project manager. Leo’s communication throughout the entire project was top-notch. As with any large commercial roofing project, we ran into a few unexpected snags along the way, but the Semper Fi team stepped up and took care of every issue with no questions asked. They stood behind their work, kept us informed, and made sure everything was handled properly. It’s refreshing to work with a company that takes responsibility and follows through on what they promise. We are very happy with the finished roof and would definitely recommend Semper Fi Restoration Inc. to anyone looking for a dependable and professional roofing company. Thank you to Joshua, Leo, and the entire Semper Fi team for a job well done!
Michael Molina
There are a lot of Roofing Contractors out there so when I was referred Josh and his team by a close friend I knew there must be something different about them. From the first meeting with Josh and Daniel I felt comfortable and at ease. I had a lot of questions and they answered them without hesitation and in extreme detail which I appreciated. They helped me through the entire insurance journey and made sure I was covered before any work was done which helped lift that burden off my shoulders. Also, you will not find a Owner as diligent as Josh when it comes to QA/QC of the work done by his crews making sure the roof/gutters you get are up to HIS standards. I appreciate Josh and Daniel for getting the work done and definitely exceeded all my expectations. I don't usually write reviews but their work deserves some praise, I will definitely be referring them anytime I hear anyone I know is even thinking of getting or needing a new roof.
Larry Walters
We had a great experience working with Joshua Bosley and Semper Fi Restoration after our home suffered large hail damage. They are honest, trustworthy, professional and knowledgeable. They held subcontractors to their high standards. This has been the best experience we have ever had with a roof replacement and other hail damage repairs. Working with Josh, Kat, and the team was a pleasure. We highly recommend Semper Fi to others! Larry and Darlene W.
Zachary Koch
I wanted to take a moment to leave a review for Josh and his team at Semper Fi Restoration. Josh came out the same day we called to provide an estimate and inspect our roof, and a member of his team completed the repairs first thing the very next morning. We truly appreciated the quick turnaround, excellent customer service, and quality workmanship in repairing the damage to our roof. The entire process was smooth, professional, and stress-free. I highly recommend Semper Fi Restoration to anyone looking for a reliable and responsive roofing company!
Lisa Smith
When my insurance refused to pay for my hail damaged roof, Semper Fi worked with my insurance to successfully get them to pay. They helped me with the entire process and communicated well. They were always available if I had questions. Their crew did a good job. They cleaned up after themselves. I highly recommend this company.
Aubrey Monckton
I had a fantastic experience with Leo at Semper Fi Restoration Inc. He recently completed some roof repairs for me, and I couldn’t be happier with the results. Leo was professional, honest, responsive, and clearly takes pride in his work. He explained everything thoroughly, showed up on time, and made the entire process smooth and stress-free. The quality of the repairs was excellent, and it’s clear he genuinely cares about doing the job right. It’s hard to find contractors you can truly trust, but Leo absolutely earned my confidence. I highly recommend Leo and Semper Fi Restoration Inc. to anyone needing roofing work or repairs. Outstanding service from start to finish!
Michael Kerr
Josh Bosley and Semper Fi Restoration recently completed hail damage work on our residence. Josh handled EVERYTHING with our insurance company. The work was completed on time, as promised. Clean-up was great. Josh came back and guaranteed we were happy with everything - including fixing two small areas that we felt needed additional work. He ensured we were 100% happy prior to moving on. He was a great communicator, very patient with us, and made us extremely happy that we chose him and Semper Fi. I rarely leave reviews - but would highly recommend him. Final note, our insurance agent recommended him to us and he was as great as advertised.
Sharine Webber
Semper Fi Restoration recently completed installing a new roof and we are so impressed with the service from start to finish. Leo Jett thoroughly explained the whole process and answered all of our questions. He was a huge help with the insurance claims and demonstrated a sincere desire to make sure everything was done professionally and to the highest standards. The crew were hard workers and also demonstrated the same commitment to completing the job right. Leo always followed up with us and made sure we didn't have any concerns or questions. We highly recommend Semper Fi Restoration!!
Jeff Cisneros
Josh is absolutely amazing, his service and follow-up is thr best I have ever experienced. The thing that really impressed me was his honesty after inspection, he shared that I didn't need a new roof. There are very few companies with that level of honesty. He has earned a customer for life.
Judy B
Leo Jett was fabulous! He walked me through every step of the process and made this a great experience. His customer service was more than I could have hoped for. After spending 25 years in the HOA business, Semper Fi would be a contractor I would recommend to anyone needing a new roof.
sukhvir singh

Thank you, Semper Fi, for an exceptional experience.

We worked with Josh and his crew to get our badly damaged roof repaired. Josh had no hesitation to get over as soon as he could walk the roof spent hours doing his inspection to make sure everything was covered not one thing was left out. He was very thorough. I am a person that wants to understand everything and he had no hesitation to explain and walk me through every process. I highly recommend Semper Fi Restoration. They are honest and will get the job done right
Gutter Installation Frequently Asked Questions
What size gutters do I need?
Five inch suits most ordinary roofs. Six inch earns its place when a big roof area drains into one run, or when the pitch is steep enough to throw water past a smaller trough. Size on its own doesn't settle it, though. A correctly sized gutter with too few outlets still spills over in a downpour.
Do I need gutters at all in a dry climate?
Yes, and it isn't really optional. Storms here deliver water in short heavy bursts rather than steadily, so a roof sheds a lot of water fast with nowhere for it to go.
Do you install gutter guards?
Yes, as part of putting a new gutter system on. We put guards on while we're replacing the gutters rather than adding them to an existing run as a job of their own, so the time to decide is at the measure. Tell us what your house sits under and we'll say whether they're worth it.
What happens if the fascia is rotten when the old gutters come off?
We deal with it before the new system goes on, and you hear about it beforehand rather than after. Nobody can see that board until the old gutter is off it, so it's the most common surprise on this job. Hanging new metal on soft wood just buys a season.
Can new gutters be financed?
Yes, through Hearth, so a full system doesn't have to wait for a good month.
Are you insured?
Yes. We carry general liability and workers compensation insurance. On a gutter job that means people on ladders around your whole house, and that risk should sit with us, not with you.
