Black Diamond Exteriors has spent more than 30 years earning trust across Central Indiana, one roof, one home, and one handshake at a time.
Black Diamond Exteriors was founded on roofing and siding, and after more than three decades in the field, we have doubled down on what we do best. Led by owner Stan Schermerhorn, we are a Westfield-based team that treats every project like it is on our own street, because very often it is.
Over the years, we watched the exterior industry fill up with companies promising to do everything: roofing, siding, windows, interior remodeling, flooring, drywall, painting, insulation, and more. We went a different direction. We made a deliberate decision to focus on the three services that protect and improve a home the most and that reward genuine specialization: roofing, siding, and decks. That focus is the single biggest reason our customers get better results and a smoother experience.
A company that tries to be everything to everyone rarely becomes the best at anything. When a crew jumps between drywall one day and roofing the next, quality suffers and details get missed. By concentrating on roofing, siding, and decks, we keep our teams sharp, our knowledge deep, and our standards high. Our roofers roof. Our siding specialists side. Our deck builders build decks. Every person who shows up at your home does that work day in and day out, which is exactly how it should be.
This focus also lets us stay ahead of the details that matter: the newest materials, the manufacturer requirements that keep your warranty valid, the flashing and ventilation techniques that decide how long a roof really lasts, and the building practices that keep a deck safe through Indiana winters. Depth beats breadth, and our customers feel the difference.
Everything we do comes back to a few simple commitments. We show up when we say we will. We communicate clearly and honestly, including when the honest answer is that you do not need the work yet. We protect your property and leave it cleaner than we found it, right down to a magnetic sweep for stray nails. And we treat your home with the same care we would want for our own. These are not slogans. They are the daily habits that built our A+ rating with the Better Business Bureau and the steady stream of five-star reviews and neighbor referrals that keep us busy.
We are certified by leading manufacturers, which means our crews are trained to install products to the exact standard required for the strongest warranties, and it gives us access to premium materials that non-certified contractors cannot offer. We are fully insured, and we handle the permits and inspections your municipality requires, whether that is Westfield, Carmel, Noblesville, Fishers, Zionsville, or Indianapolis. Most importantly, we are local and accountable. When you call after the job is done, you reach the same company that did the work, not a chain that has moved on to the next market.
We live and work in Central Indiana, and our reputation is tied to the homes we improve here. That local connection shapes how we work. It makes us responsive when a storm rolls through, careful with the homes and neighborhoods we serve, and genuinely invested in doing right by our customers, because they are our neighbors and their referrals are our lifeblood. When you hire Black Diamond Exteriors, you are not a work order. You are part of the community we are proud to serve.
Thirty years is a long time in any trade, and in exterior work it shows up everywhere that matters. It shows up in the roofs still performing beautifully a decade after we installed them, in the siding that has kept homes dry through countless Indiana winters, and in the decks that families are still gathering on years later. It shows up in the relationships we have built with manufacturers, which give our customers access to premium products and stronger warranties. And it shows up in the simple confidence of knowing how to handle whatever a project reveals, because after three decades there are very few surprises we have not seen and solved before. When you hire us, that entire history of experience goes to work on your home.
When you choose Black Diamond Exteriors, you are getting more than a roof, siding, or a deck. You are getting a commitment. We guarantee work completed to manufacturer specification by our own trained specialists, backed by strong material and workmanship warranties that we explain to you before we begin. We guarantee a clean, respectful process that protects your property throughout. And we guarantee that if you have a question or concern after the job is done, you will reach the same local company that did the work, ready to make it right. That accountability is the heart of everything we do.
In a business where anyone can print business cards and call themselves a contractor, reputation is everything, and it is earned one job at a time. That is exactly how we have built ours over more than three decades. Every roof we install, every home we re-side, and every deck we build is a visible, lasting example of our work that our neighbors can see and that our next customer can trust. We never forget that the quality of today's project determines whether we earn tomorrow's referral. It is why we sweat the details, stand behind our work, and treat every home as a chance to prove ourselves again.
