The roofing sub your schedule can actually rely on.

Why GCs and architects keep our number

On a commercial build, the roofing contractor sits in the middle of everyone else’s schedule. Framing can’t hand off, mechanical can’t set units, and interior trades can’t start until the building is dried in. A roofer who slips a week can cost a project a month.

That’s why general contractors across Bluffton, Hilton Head Island, Hardeeville, and the greater Savannah area keep coming back to Ragsdale Roofing and Innovations. Since 2014 we’ve installed commercial roof systems with our own in-house crews — no subcontractors subbing to sub-subcontractors — which means when we commit to a dry-in date, the people who have to hit it work for us. Licensed, bonded, and BBB A+ rated, with 25+ years of combined experience behind every bid we submit.

What goes into a low-slope roof done right

A flat or low-slope commercial roof isn’t one product — it’s an engineered assembly, and every layer earns its place:

1. The deck. Steel, wood, or concrete — we verify it’s clean, dry, and ready before anything goes down, because every layer above inherits its condition.
2. Insulation. Rigid boards sized to meet the energy code and, where the design calls for it, tapered to build positive slope into a structurally flat deck.
3. Cover board. The unsung hero of a durable roof — a dense layer that protects the insulation from foot traffic, hail, and dropped tools for the next few decades.
4. The membrane. The waterproofing layer itself, attached per the specified method — mechanically fastened, fully adhered, or induction welded — with every seam and penetration detailed to manufacturer requirements.
5. Edge metal and terminations. Coastal wind gets its first grip at the roof edge. Perimeter metal, copings, and terminations are fabricated and fastened for the wind zone this coast actually lives in, not a generic detail from a milder market.

Drainage designed for Lowcountry rain

Bluffton doesn’t get gentle rain; it gets afternoon thunderstorms that drop an inch in an hour and tropical systems that drop far more. On a low-slope roof, that water has to be gone before it becomes a load or a leak. We work with your design team on tapered insulation layouts, crickets behind curbs, and properly sized drains, scuppers, and overflows — so the roof sheds water by design rather than ponding by accident. It’s the least glamorous part of a roof package and the one that most decides how long the roof lasts.

Spec compliance, submittals, and paperwork that flows

Commercial work runs on documentation, and we don’t treat it as an afterthought. Ragsdale Roofing and Innovations bids to your spec section as written, flags conflicts or substitution opportunities up front rather than mid-install, and turns submittals around promptly — product data, details, and warranty terms in the format your architect expects. During the install we coordinate inspections, and at closeout you receive the executed warranty documentation and as-built photo record without having to chase us for it.

Coordination is the job

• One point of contact from bid to closeout — a person who answers, knows your project, and can give you a real status instead of a guess.
• Sequencing with other trades. We plan around steel erection, rooftop unit sets, and plumbing penetrations so nobody is standing on our membrane before it’s protected — and nobody is waiting on us.
• Weather-realistic scheduling. We build hurricane season and daily storm patterns into the plan instead of pretending August in South Carolina behaves like April.
• Clean, safe sites. Daily housekeeping and disciplined material staging — the habits that keep a project’s safety record and its schedule intact at the same time.

After the ribbon cutting

A new roof deserves a long life, and that life is largely decided in its first few years of care. Many of the buildings we roof move straight onto a commercial maintenance program — semi-annual inspections that keep the manufacturer’s warranty conditions satisfied and catch small issues while they’re cheap. Down the road, our commercial repair and replacement teams are the same company, same standards, same phone number. Building a custom home instead of a commercial project? Our residential roof installation crews work the same way with homebuilders.
