Johnson Roofing & Sheet Metal: What They Do and How to Reach Them

What Johnson Roofing & Sheet Metal Offers

Johnson Roofing & Sheet Metal is a roofing contractor based in South Carolina that handles both residential and commercial roof work, along with custom sheet metal fabrication and installation. The company works with standard roofing materials—asphalt shingles, metal panels, and flat roof systems—and can handle repairs, replacements, and new construction. They also take on sheet metal projects like gutters, downspouts, flashing, and custom metal work for both new builds and existing structures.

Like most roofing contractors in the state, Johnson Roofing & Sheet Metal operates within South Carolina's building codes and licensing requirements. They typically work with homeowners, property managers, and commercial clients who need estimates, inspections, or ongoing maintenance. The company's dual focus on roofing and sheet metal means they can often handle both the primary roof system and the metal components that protect seams and edges—work that sometimes requires coordination between separate trades.

Key Takeaways

• Johnson Roofing & Sheet Metal handles residential and commercial roofing, including repairs, replacements, and new installations across multiple material types.
• The company also fabricates and installs custom sheet metal work such as gutters, flashing, and downspouts, often as part of the same project.
• You can contact them directly for a roof inspection, damage assessment, or estimate before committing to any work.
• Like all South Carolina roofing contractors, they must be licensed and follow state building codes for the work they perform.

How to Get in Touch with Johnson Roofing & Sheet Metal

The most direct way to reach Johnson Roofing & Sheet Metal is by phone or through their website if they maintain one. When you call, have ready a description of what you need—whether it's a roof inspection after a storm, a quote for a full replacement, or a specific sheet metal project. They will typically ask about your roof type, the age of your current roof, and the scope of work you're considering.

Many roofing contractors in South Carolina schedule free or low-cost initial inspections, especially for damage claims or insurance-related work. If you're dealing with storm damage or a leak, mention that when you contact them so they can prioritize your call and bring the right tools to the inspection.

What to Expect During an Inspection or Estimate

When Johnson Roofing & Sheet Metal comes to your property, they will typically walk the roof (or use a drone or ladder inspection if safety is a concern), photograph any damage or wear, and document the current condition. For repair work, they'll identify the specific problem—a leak source, missing shingles, deteriorated flashing, or compromised seams. For replacement estimates, they'll measure the roof area and discuss material options with you.

Sheet metal work is often identified during this inspection too. If gutters are clogged, downspouts are damaged, or flashing around chimneys or vents is failing, the inspector will note it. This matters because water damage often starts at the edges and seams, not the main roof surface itself. A complete estimate will usually break out roofing and sheet metal costs separately so you can see what each part of the project covers.

Roofing Materials and Options They Work With

Johnson Roofing & Sheet Metal works with the most common roofing materials available in South Carolina. Asphalt shingles remain the standard for residential homes because they're affordable and durable in the state's humid climate. Metal roofing—standing seam panels or metal shingles—is increasingly popular for both residential and commercial work because it lasts longer and handles heavy rain and wind better than asphalt.

For flat or low-slope roofs common on commercial buildings and some modern homes, they install systems like TPO (thermoplastic polyolefin), EPDM rubber, or built-up roofing. Each material has different costs, lifespans, and maintenance needs. During your estimate conversation, ask them to explain the trade-offs for your specific situation—a metal roof costs more upfront but may last 40 to 50 years, while asphalt shingles typically last 15 to 25 years depending on weather exposure.

Sheet Metal Work Beyond the Roof

Sheet metal fabrication and installation is often overlooked until something fails. Gutters and downspouts channel water away from your foundation—when they're clogged, damaged, or improperly pitched, water pools against the house and can cause basement leaks or foundation damage. Flashing around chimneys, skylights, vents, and roof penetrations seals the gaps where the roof meets other structures; failed flashing is one of the most common sources of interior leaks.

Johnson Roofing & Sheet Metal can custom-fabricate metal components to fit your specific roof design, which matters for older homes or unusual architectural features. They can also install gutter guards, repair or replace downspouts, and re-seal or replace flashing as part of a maintenance plan. Having one contractor handle both the roof and the metal work often means better coordination and fewer gaps in the warranty or responsibility if something goes wrong.

Working with Insurance and Damage Claims

If your roof was damaged by a storm, hail, or wind, your homeowner's or commercial insurance may cover repairs or replacement. Johnson Roofing & Sheet Metal can work with your insurance company on damage assessment and claims. Many contractors in South Carolina are familiar with the insurance process and can provide detailed estimates and photographs that support your claim.

When you contact them about storm damage, let them know you'll be filing a claim. Some contractors can coordinate directly with your adjuster or provide documentation in the format your insurance company needs. This doesn't change what you pay out of pocket—your deductible remains the same—but it can speed up the approval process and ensure the estimate aligns with what the insurance company will reimburse.

Questions to Ask Before Hiring

Before you commit to any roofing or sheet metal work, confirm that Johnson Roofing & Sheet Metal holds a current South Carolina roofing license and carries liability insurance. Ask for references from recent residential or commercial projects similar to yours. Find out whether they provide a written warranty on materials and labor, and what that warranty covers—some warranties are limited to defects in materials, while others cover workmanship for a set period.

Ask about their timeline. How long will the project take? Will they need roof access for multiple days? What happens if weather delays the work? For sheet metal projects, ask whether they'll handle disposal of old gutters or flashing, or if that's your responsibility. Clear answers to these questions before work begins prevent surprises later.

Frequently Asked Questions

How do I know if my roof needs repair or replacement?

A contractor's inspection is the only reliable way to know. Signs that suggest replacement might be needed include multiple missing or curling shingles, visible sagging, interior water stains, or a roof older than 20 years. Repairs work for isolated damage—a few missing shingles, a small leak, or damaged flashing. Johnson Roofing & Sheet Metal can assess your specific roof during an inspection and recommend the most cost-effective option.

What's the difference between TPO and EPDM roofing?

Both are flat-roof materials, but they differ in cost, durability, and installation. TPO is typically less expensive and energy-efficient (it reflects heat), while EPDM is a rubber material that's been used longer and has a proven track record. EPDM is darker and absorbs heat, which can increase cooling costs. Ask Johnson Roofing & Sheet Metal which material suits your building's climate, usage, and budget during your estimate.

Can I repair gutters myself, or should I hire a contractor?

Minor gutter cleaning and small repairs are often DIY-friendly, but gutter replacement, re-pitching, or custom fabrication should be done by a professional. Gutters must slope correctly to drain water, and improper installation can cause foundation damage. Johnson Roofing & Sheet Metal can handle gutter work as part of a larger roofing project or as a standalone service.

Do I need a permit for roof replacement in South Carolina?

Most roof replacements require a building permit from your local city or county. The contractor typically handles permit applications as part of their service, though you may need to pay the permit fee. Ask Johnson Roofing & Sheet Metal whether permits are included in their estimate and what the timeline is for permit approval in your area.

What should I do if I notice a roof leak?

Contact Johnson Roofing & Sheet Metal for an inspection as soon as possible. In the meantime, place a bucket under the leak and photograph the water stain or damage. If it's raining, try to identify where water is entering from the attic or upper floor. The faster you address a leak, the less interior damage occurs. Many contractors offer emergency or same-day inspections for active leaks.
