Types of work Johnston Roofing performs
Johnston Roofing handles three main categories of work. New installations apply when you are building a structure or adding a roof to an existing building. Repairs address specific damage—a leak, missing shingles, flashing problems, or storm damage—without replacing the entire roof. Replacements involve removing an old roof system and installing a new one, which becomes necessary when a roof has reached the end of its lifespan or damage is too extensive to repair cost-effectively.
The company works on both residential homes and commercial buildings, so the scale and complexity of projects can vary widely. A residential repair might take a day or two, while a commercial replacement could span weeks. Johnston Roofing can discuss which category your situation falls into once you describe the problem.
How to contact Johnston Roofing for an estimate
To get in touch with Johnston Roofing, you will need to reach out directly by phone or through their business contact information. Have the following details ready when you call: your address, a description of the problem (leak, storm damage, age of the roof), and your availability for an estimate visit. If you have photos of the damage, those help the contractor understand the scope before arriving.
Most roofing contractors, including Johnston Roofing, provide estimates at no cost. The estimate visit typically takes 30 minutes to an hour, during which the contractor inspects the roof, discusses material options and pricing, and answers your questions. You are under no obligation to hire them after receiving an estimate.
What to prepare before the estimate visit
Before Johnston Roofing arrives, gather any documentation you have about your roof. If you know when the roof was installed or last replaced, that information is useful—most asphalt shingle roofs last 15 to 20 years, so age helps determine whether repair or replacement makes sense. If your roof is still under warranty, locate the paperwork; some warranties cover certain types of damage or repairs.
Clear the area around your home if possible so the contractor can access the roof safely and see the full scope of any damage. If you have experienced a recent storm, document the damage with photos and note the date. This information helps the contractor assess whether the damage is recent and may be covered by homeowners insurance.
Understanding roofing material options
When Johnston Roofing discusses your replacement or new installation, they will likely present material choices. Asphalt shingles are the most common and affordable option in South Carolina; they come in various colors and styles. Metal roofing is more durable and reflects heat, which can lower cooling costs in our climate, but costs more upfront. Architectural or premium shingles offer better appearance and longevity than standard asphalt but at a higher price.
Each material has different lifespans, maintenance needs, and price points. The contractor can explain how each option performs in South Carolina's heat and humidity. Your choice depends on your budget, how long you plan to stay in the home, and your priorities—whether that is lowest cost, longest lifespan, or energy efficiency.
Questions to ask during the estimate
Use the estimate visit to understand the full scope of work and costs. Ask Johnston Roofing how long the project will take, whether they handle permits and inspections, and what warranty they offer on their work. Clarify whether the price includes removal of the old roof, disposal of debris, and any repairs to the underlying structure if damage is found during installation.
Ask about their crew size and timeline—will they complete the work in one day, or will it span multiple days? Understand what happens if weather delays the project. Ask whether they carry liability insurance and workers' compensation, which protects you if someone is injured on your property. A professional contractor will answer these questions directly and provide a written estimate that breaks down labor and materials.
Insurance and payment considerations
If your roof damage resulted from a storm, your homeowners insurance may cover part or all of the repair or replacement cost. Before hiring Johnston Roofing, contact your insurance company to file a claim and request an adjuster visit. The adjuster will assess the damage and determine what your policy covers. Some contractors work directly with insurance companies and can coordinate the claim process with you.
Discuss payment terms with Johnston Roofing before signing a contract. Many contractors require a deposit to schedule the work and final payment upon completion. Avoid paying the full amount upfront; a typical arrangement is a deposit (often 25 to 50 percent) and the balance due when the work is finished and inspected. Get the payment terms in writing as part of your contract.
Frequently Asked Questions
How do I know if my roof needs repair or replacement?
If your roof is leaking in one or two spots, is under 15 years old, and the damage is isolated, repair is usually the answer. If your roof is over 20 years old, has multiple leaks, or shows widespread damage, replacement is often more cost-effective. Johnston Roofing can assess this during an estimate and recommend the best option for your situation.
What should I do if I notice a leak?
First, contain the water damage inside your home—place buckets under drips and move valuables away from the affected area. Take photos of the leak and any visible damage. Then contact Johnston Roofing or another contractor to schedule an inspection. Do not wait; small leaks can worsen quickly and cause structural damage.
Does Johnston Roofing handle storm damage claims?
Many roofing contractors work with insurance companies on storm damage claims, though you should confirm this directly with Johnston Roofing. If your roof was damaged by a storm, contact your insurance company first to file a claim. The contractor can then work with your adjuster to document the damage and coordinate repairs.
How long does a roof replacement typically take?
A residential roof replacement usually takes one to three days, depending on the size of the roof, weather conditions, and whether underlying damage is found. Johnston Roofing can give you a specific timeline during the estimate based on your home's roof size and complexity.
What warranty should I expect on roofing work?
Contractors typically offer a warranty on their labor (usually one to ten years) and the materials come with a separate manufacturer's warranty (often 15 to 30 years for shingles). Ask Johnston Roofing what they may provide on their workmanship and get the warranty terms in writing before signing the contract.
