Commercial Roof Maintenance in Centennial, CO

Spring and fall damage reports on Centennial's office and retail buildings. Semper Fi Roofing walks the roof, photographs it, and writes down what changed, because hail can take years off a flat roof without a drop reaching a ceiling tile.

Hail Damage That Doesn't Leak

Hail Damage That Doesn't Leak

Centennial sits in an active part of the hail corridor. Storms come around often enough that most buildings here have been through several.

A shingle roof tells on itself after a storm. Granules in the gutter, a slope that looks different from the driveway. A flat roof doesn't.

Hail bruises the membrane and the board underneath it. Nothing opens. Nothing drips. The roof still keeps water out, and it does that for a while. What actually happened is its life got shorter, in a way invisible to everybody standing inside the building.

The alternative to going up is finding out years later. By then the roof fails early and nobody can say which storm did it.

Getting the First Visit Done Before Summer

Getting the First Visit Done Before Summer

There's no bad time to start, but there's a better one.

A first report done ahead of the storm months is worth more than the same report done after them. That's because it becomes the before picture.

It's worth having whether or not there's a claim in your future:

  • You find out what's actually on the roof, including anything a tenant's contractor put up there without telling you.
  • Small items stay small. Found in the fall, a failing detail is a smaller job. Found after a winter of water getting into it, it's a bigger one.
  • You can budget from it. We split each item into what needs doing and what needs watching.

If a report does turn up work, we quote it on its own so you can look at it separately. What you do about it is your call.

Our Process

Two visits a year, one in spring and one in fall. They're looking for different things, because the two halves of a Colorado year damage a roof differently.

The fall visit comes after the storm months. June is the heavy part of hail season here. So by the time it's over, whatever the summer did is already on the roof. We find it on the fall walk and close it up before the cold arrives.

The spring visit comes after the wind and the cold. The Greater Denver Area takes its high wind in the cold months rather than in summer. Wind works at the edges of a flat roof. Then freezing and thawing works at whatever the wind opened. On the spring walk we find what the winter did.

On both walks:

  • We look at the surface where the hail landed, not just where a stain has appeared.
  • We photograph bruising and scatter and pin it to a spot, so it's on record right away.
  • We walk the same roof in the same order every visit, so one report is comparable with the last.

Between them you get something better than either report on its own. Two dated sets of photographs a year, in the same order, so what changed is visible instead of remembered. We're licensed and insured, and nobody shows up on your property without a background check behind them.

    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

    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

    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!

    Josh Slankard with Semper Fi Restoration who orchestrated the entire roofing replacement and Paint Denver who made my 20 year old home look better than it ever did I send my heart felt thanks for you. I would recommend this company with 5 stars!

    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.

Working with Josh, Kat, and the team was a pleasure. We highly recommend Semper Fi to others! Larry and Darlene W.

    Josh and his crew provided exceptional service! He provided an estimate for what we needed, which wasn’t a full roof replacement. Professional, polite and knowledgeable - I highly recommend Semper Fi Restoration and will definitely use them in the future!

    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!

    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.

    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!

    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.

    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.

    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.

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.

Commercial Roof Maintenance in Centennial FAQs

The roof looked fine from the lot after the last storm. Is a visit worth it?

That's exactly the case for going up. Hail bruises a flat roof without opening it. So a roof that's taken real damage looks unchanged from the ground and stays dry inside for a while. The only way to know is for us to get on it.

Will the reports help if I file a hail claim?

Yes, and it's one of the better reasons to have them. Dated photographs from before a storm answer the question insurers push hardest on, which is whether the damage is new. We also pull the hail history for your building's address rather than for the city. The estimate goes out in the format your carrier reads.

If the report finds something, am I committed to fixing it with you?

No. The report tells you the condition of your roof and separates what needs work from what needs watching. We quote anything that needs doing on its own, and you can take that quote anywhere.

I hold more than one building around Centennial. Can they all go on this?

Yes, and that's where it earns its keep. Each building gets its own report. That way you can see across the whole set which roofs need budget this year and which can wait.

Do you do this on residential properties too?

No. The spring and fall damage reports are for commercial buildings only. A flat roof sits out of sight and hides damage in a way a shingle roof doesn't. That's what makes a twice yearly record worth having on one and not the other.

What does the first visit cost?

Nothing. The roof walk and the estimate are free, whatever the walk turns up.

Start Reports on Your Centennial Roof

Send us the address and we'll come out, walk the roof and write up what's there. That first report becomes the record everything after it gets measured against.
