IronCrest was founded in 2006 by a roofer who got tired of watching the industry treat workmanship as optional. 18 years later, nothing has changed about that conviction.
IronCrest Roofing Co. was founded in Denver, Colorado in 2006 by Garrett Voss, a third-generation roofer who spent eight years working for large roofing chains and watching the same pattern repeat: high-volume bids, subcontracted crews, minimal quality oversight, and clients left wondering if what happened under their new shingles was actually done properly.
Garrett started IronCrest with one foundational rule: every crew member is an employee. Not a subcontractor. Not a day laborer called in to hit a schedule. An employee who wears our name on their truck, who has been trained to our standards, and who is accountable to us — and through us, to you.
That model costs more to run. It shows in our pricing. And it shows in the quality of work delivered on every single job — whether it's a 1,200 sq ft residential repair or a 60,000 sq ft commercial replacement.
Today IronCrest operates with 112 full-time employees across Colorado, Wyoming, Utah, Montana, and 12 additional states. We hold Owens Corning Platinum Preferred status, Atlas ProPlus certification, and have maintained a BBB A+ rating for 14 consecutive years. Over 7,200 roofs carry our name — and our direct warranty.
Every crew member is a full-time IronCrest employee. Trained, insured, and accountable. We don't outsource quality to the cheapest available crew.
Complete photo documentation at every stage. You see exactly what was done under your shingles — before we ask you to sign an invoice.
We've never issued a surprise invoice. If scope changes, we stop, document, and get your written sign-off before proceeding. Always.
