Roofer

Roofers install and maintain one of the most critical systems in any building — the barrier that keeps everything inside dry. The work is done outdoors, at elevation, in direct weather, and the product has to perform for decades without leaking. There's a kind of simplicity to the job's standard: either the roof keeps water out or it doesn't, and the customer will definitely know the difference.

On residential re-roofing work, which makes up a large share of the industry's volume, the day starts early. Tear-off crews strip existing shingles, inspect the deck for rot or damage, replace damaged sheeting, and set up for the new installation. The installation sequence — starter strip, underlayment, flashing at all penetrations and valleys, field shingles, ridge cap — has to follow the manufacturer's installation requirements to maintain the warranty. Shingle roofers who cut corners on nail pattern, exposure, or flashing get callbacks, and callbacks kill productivity.

Commercial membrane work is slower and more detail-intensive. TPO seam welding requires maintaining proper temperature and speed across every linear foot of seam on a roof that might have 50,000 square feet of membrane. Seam quality is tested by probing with a screwdriver — an open seam fails immediately. Penetration details — the places where pipes, drains, and HVAC curbs interrupt the membrane — are where most commercial roof failures originate, and experienced roofers give them disproportionate attention.

Fall protection is part of every roofer's daily setup. Whether it's setting up warning line systems on a flat commercial roof, installing guardrails on a residential peak, or tying off to a roof anchor, the system has to be in place before anyone works at the roof edge. The industry's safety record has improved significantly as OSHA enforcement and contractor programs have made fall protection culturally normal rather than optional.

Entry paths:

• JATC (Joint Apprenticeship Training Committee) through the United Union of Roofers, Waterproofers and Allied Workers — 3-year apprenticeship with classroom and field training
• Direct hire as a laborer with roofing contractors, advancing through demonstrated skill and reliability
• Roofing trade school programs (rare; most training is on the job)

Certifications:

• OSHA 10 Construction (standard requirement at many commercial contractors)
• Manufacturer certifications: GAF Master Elite, Owens Corning Platinum Preferred, Johns Manville Contractor programs
• NRCA (National Roofing Contractors Association) ProCertification for commercial roofers
• Hot work permit authorization for torch-applied membrane systems
• Welding certification for TPO/PVC heat-welded seams (major commercial contractors)

Physical requirements:

• Comfortable working at elevation — residential steep slope and commercial roofs both require comfort with heights
• Heavy lifting: shingle bundles run 65–80 lbs; roofing equipment is heavy
• Working in hot, sunny conditions — rooftop temperatures in summer can exceed 140°F on dark membrane
• Good balance and agility on sloped surfaces

Technical knowledge:

• Roofing systems: asphalt shingles, TPO, EPDM, modified bitumen, metal panels, built-up roofing
• Flashing systems: step flashing, counter-flashing, lead pipe jacks, HVAC curb flashing, expansion joints
• Drainage: internal drain systems, scuppers, overflow protection
• Fall protection systems: guardrail requirements, personal fall arrest system selection and inspection
• Reading roofing specifications and manufacturer technical bulletins

Demand for roofers is driven by both new construction and replacement activity. New construction creates a one-time installation need; the replacement cycle creates ongoing demand as roofs age out. Commercial flat roofing systems have 15–25 year useful lives; residential shingle systems run 20–30 years. Given the volume of commercial and residential construction that occurred in the 1990s–2010s, a significant replacement wave is underway.

Weather events are accelerating roof replacement activity. Hail storms, hurricanes, and winter ice damage drive insurance-funded replacement volume that tracks storm activity rather than economic cycles. In hail-prone markets (Texas, Colorado, the central plains), storm-chasing roofing contractors generate high volumes of residential replacement work that can compress entire years of replacement activity into weeks after a major storm.

The residential roofing labor market is tight. Roofing is physically demanding, weather-dependent, and has high injury rates compared to other construction trades — factors that reduce the pool of workers willing to do it long-term. Production roofing for homebuilders, which involves repetitive installation of the same shingle systems on similar homes, turns over staff quickly but provides good entry-level training for workers who want to advance into commercial or specialty roofing.

For roofers who develop commercial membrane skills — particularly TPO welding, sheet metal work, and multi-system roofing on complex commercial buildings — compensation and job security improve substantially. Lead mechanics and foremen on commercial roofing projects earn $70K–$90K in most markets, and the overlap between roofing, waterproofing, and building envelope work creates a wide career path.

Photovoltaic roofing integration is an emerging specialization. Roofers who understand both roofing systems and solar installation are positioned for growing demand as building-integrated PV products continue developing.

Dear Hiring Manager,

I'm applying for the Roofer position at [Company]. I've been in the roofing trade for six years — two years in residential shingles to learn the basics, then four years focused on commercial low-slope work with [Contractor], primarily TPO and modified bitumen on industrial and institutional projects.

My current work centers on large commercial roof replacement jobs: tear-off, deck inspection and repair, new insulation and cover board, and single-ply membrane installation. I'm experienced with hot-air welding on TPO using Leister and Miller Weld Master equipment, and I've passed seam quality audits on all jobs where we had third-party inspection. The detail work — penetration boots, inside and outside corners, expansion joints — is where I spend the most time and attention, because that's where leaks start if you're not careful.

Last spring I was the lead mechanic on a 60,000-square-foot warehouse re-roofing project where the owner had an extremely compressed schedule — they needed the membrane in place before their inventory arrived. We ran a two-crew system for the membrane phase, which required me to coordinate welding equipment positioning and overlap sequences between crews across two roof sections. We finished the membrane 10 days ahead of the milestone.

I'm looking for a commercial roofing contractor with a variety of project types — I'd like more exposure to standing seam metal and vegetative roof systems to round out my experience. [Company]'s project portfolio looks like the right environment for that.
