About Celtic Roofing
Colorado-Born, Family-Run Since 2008
Founded by Eian McKinley in Castle Rock, we've spent the last 17 years earning our reputation the old-fashioned way — one handshake, one honest estimate, and one well-built roof at a time.

The Celtic crew treated my home like it was their own. Clean job, honest price, and a roof that survived the next hail storm without a scratch.

Roofing built on trust, craftsmanship, and Colorado grit.
Since 2008, Celtic Roofing has earned its reputation the old-fashioned way — one honest estimate, one handshake, and one well-built roof at a time. We started in Castle Rock and haven't lost that small-town accountability.
Every project gets a dedicated project manager, manufacturer-backed materials, and a workmanship guarantee. We don't cut corners — we cover them.

Frequently Asked
Questions From Colorado Homeowners
Most residential replacements wrap up in one to two days. Larger or more complex roofs can take three. We pull permits, protect your landscaping, tear off the old roof, and haul it away the same day.

Yes. We work directly with your insurance adjuster — documenting damage, meeting on-site, and making sure nothing gets missed in the scope of work. Most of our customers pay only their deductible.
Manufacturer material warranties of 25–50 years plus our 5-year workmanship warranty on every install. We stand behind every roof we put on.
Licensed in every Colorado jurisdiction we work in, fully insured for liability and workers' comp. We're happy to share certificates upon request.
Our Process
What To Expect From Day One
From first phone call to final cleanup — here's how we work.
We walk your roof, photograph every issue, and send you a detailed written estimate within 48 hours.
You pick the shingle line, color, and accents — we bring samples to your home so you can match them to your siding and trim in natural light.
Crews arrive early, lay protective tarps, remove the old roof, and install the new system. We sweep for nails before we leave.
The owner or project manager walks the home with you, inside and out, before we hand over the keys and your warranty paperwork.
