Commercial Roof Repair in Centennial, CO
Leaks on Centennial's offices and retail buildings. Semper Fi Roofing traces the water from the roof down, then fixes the thing that's actually letting it in. On a building full of separate suites, what sits under the leak decides what we deal with first.
Where the Water Shows Up Inside

On a Centennial office building you usually don't find the leak. A tenant does, and by then it has been coming in for a while.
What they report is a ceiling tile. A stain that got bigger, a tile that sagged, or a drip somebody put a bin under. That's a long way from the roof and it's a long way from where the water got in.
So the first question we ask is not where the stain is. It's what sits underneath it.
- Water over a server room, an electrical panel or a records store changes the order of work. Keeping it off the thing that matters comes before the permanent fix.
- Water over a leased suite brings the tenant into the conversation. Roof access and work above them both have to be arranged with them.
- Water over open floor is the easiest version, and it's still worth photographing inside before anything gets cleaned up.
Our Process

- Tell us what's under the leak when you call. On a building full of suites, that one fact changes what happens first. More than the size of the hole does.
- We trace it from the roof down, because that's the only way to find where the water actually starts.
- We photograph what's up there rather than describing it, so the evidence exists before anybody argues about it.
- We pull the hail history for your building's address, not for Centennial as a whole. Storms land in strips, so a city-level answer tells you almost nothing about your own roof.
- Where it is a claim, our estimate goes out in the format your carrier reads. The estimating and the supplementing stay in house.
- Where a permit is needed we pull it and call the inspections. That part is not yours to chase. Semper Fi Roofing is licensed and insured. Everyone we send on site has had a background check.

Telling Storm Damage Apart From Ordinary Wear
Centennial gets hit often. Hail here runs heaviest in June. It comes around often enough that most buildings have been through several storms already. That makes one question genuinely hard to answer from underneath: is this repair a claim or not?
Wear looks like a roof that has aged evenly. Seams tired across the whole plate. Surface thinning where people walk. Sealant given up at the joints it was always going to give up at.
Storm damage looks different. Bruising in a scatter across the field. A tear rather than a split. Edge metal moved. Damage that stops at a line, because that's where the storm stopped.
Where it isn't a claim, you'll hear that too. A repair priced honestly on a roof that's simply worn is still a repair worth doing.
The Greater Denver Area takes its high wind in the cold months rather than in July. Wind doesn't usually tear the middle out of a membrane. It works at the edges, because that's where it can get underneath.
- The perimeter metal takes the load first. Once a length of it lifts, the membrane edge behind it has nothing holding it down.
- Corners take more than the middle. Wind accelerates around them, so that's where fasteners work loose.
- Anything already lifted catches the next gust. A small opening in November is a much larger one by March.
None of that is visible from the parking lot, and none of it necessarily leaks straight away. What tends to happen is a winter of wind opening an edge. Then the first serious rain of the year finds it. If your building started leaking in spring, the cause is often several months older than the leak.

What Building Owners 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.

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
Commercial Roof Repair in Centennial FAQs
The building took hail last summer and it started leaking this spring. Is that still a claim?
It can be. Hail bruises a flat roof without necessarily opening it, so the damage and the leak can be months apart. What settles it is evidence from the roof plus the hail history for your address. We gather both, then give you a straight answer either way.
Nothing on the roof looks torn. Can wind still be the cause?
Yes, and it's common here. Wind works at the perimeter rather than the middle. A lifted length of edge metal, or a run of loosened fasteners, does the damage with nothing obvious to see. That's the part of a roof we check first after a windy stretch.
Water is coming in over our server room. What happens first?
Protecting what's underneath comes before the permanent repair. Tell us what's under the water when you call and it changes the order we work in. We still trace it from the roof, because that's the only way to find where the water actually starts.
Can you repair a roof another company installed?
Yes, and a good share of what we fix is somebody else's work. It doesn't change how we trace it. We'll ask what you know about the roof's history before anyone touches it.
Does a repair on my building need a permit?
Depends on the work and on which authority your parcel actually sits in, which isn't always the one your mail suggests. We check the address and settle that before we quote.
Do I need to be there while you're on the roof?
No. What we need is the address, a way onto the roof, and a note of where the water is showing up inside. We send you the photographs and the findings afterwards either way.
What does it cost to have the leak looked at?
Nothing. The roof walk and the estimate are free, whatever the trace turns up. You'll get photographs of your own roof and a plain explanation of where the water is getting in.

Tell Us Where the Water Is
Send us the address and a note about what's underneath the leak. We'll get on the roof, trace it back, and price the fix. The walk and the estimate cost you nothing.
