Founded on the principle
that measurement
beats guesswork.
Since 2011, Blooms Roofing has operated with one constraint: every recommendation must be defensible with documented evidence. No scope inflation. No assumption-based proposals. Just data.
Built from dissatisfaction
with the status quo.
Marcus started as a forensic building consultant — the person insurance companies and law firms called after roofing failures. He reviewed hundreds of failure reports, deposed dozens of contractors, and saw the same pattern repeatedly: scope decisions made on visual assumptions that thermal imaging would have resolved in minutes.
In 2011, he founded Blooms Roofing with a single operational rule: no scope recommendation is issued without documented thermal and structural measurement. The company acquired its first ITC-certified thermographer that same year — before thermal imaging was anywhere near standard practice in the residential roofing industry.
Today, Blooms employs 85 full-time licensed professionals, operates across Michigan, and has completed more than 5,200 roofing systems. Marcus still reviews every warranty claim personally. The rule hasn't changed.
How we make decisions.
These aren't aspirational values on a wall — they're operational policies enforced through our compensation structure, inspection protocols, and client contracts.
Measurement Before Recommendation
Every scope of work is derived from documented thermal and structural findings. We don't propose work we can't justify with data. This policy has cost us projects where customers wanted fast answers — and earned us customers who value precision.
Minimum Necessary Scope
Our inspectors are trained to identify the minimum scope that resolves the documented problem — not the maximum billable opportunity. Compensation is structured around inspection accuracy, not project value. That structure produces fundamentally different advice.
Written Accountability
Every commitment is in writing before work starts: scope, specifications, timeline, payment schedule, warranty terms. If it isn't in the signed contract, the burden falls on us — not you. We've honored that principle on every project since 2004.
Verification, Not Just Inspection
We perform post-installation thermal verification on every replacement to confirm that previously identified anomalies are resolved. You receive written confirmation before final payment is due. We know of no other residential contractor in the Southeast that does this.
Continuous Technical Mastery
Materials science advances. Code requirements update. Installation techniques improve. Every Blooms technician completes 80+ hours of continuing education annually. We fund this as though it were billable time, because the alternative is skill drift — and skill drift causes failures.
Community Accountability
Blooms completes 10–14 Habitat for Humanity installations annually, provides discounted assessments to qualifying veterans, and sponsors a roofing science apprenticeship program for underrepresented communities. Strong communities start with sound structures.
