How To Choose a Roofing Company

Installing a new roof is a large home improvement project that can cost tens of thousands of dollars. It’s crucial to do your research and find the top-rated company for the job. Here are the key factors to consider when selecting a roofer.

• Roofing materials and products: Leading manufacturers produce durable roofing materials that can withstand Greenville's weather for years. Avoid contractors offering low-cost or generic products. Check out shingle samples before making a decision.
• Detailed written estimate: Quality roofers will provide a thorough written proposal. The estimate should detail the full project scope, materials to be used, and total cost with no surprise charges. Avoid companies that provide unclear bids, or ones that seem way too low or high.
• Experience and credentials: Seek out providers that have been operating for at least 10 years. These companies' longevity and years in business reflects consistent work, knowledgeable teams, and happy former customers. Ensure a provider has appropriate licenses, bonds, and insurance before hiring. Also ask about professional certifications, such as those from the National Roofing Contractors Association.
• Warranties and guarantees: Reputable roofing companies offer robust warranties that cover your roof. Look for coverage on shingles lasting 30+ years, plus at least a 5-year guarantee on labor. Avoid companies that have less coverage than that.
• Responsiveness and communication: From estimate to project completion, the company should regularly communicate with you, respond to all questions, and address any concerns.
• References and reviews: Research companies carefully by reviewing their profiles on review sites such as Google, Yelp, or the Better Business Bureau (BBB) and looking for years of consistently positive feedback. You can also request recent local references.

Signs Your Roof Needs Repair or Replacement

While most homeowners don't think about their roof every day, it plays a key role in protecting your home. Look out for these common signs that your roof may need an inspection and repairs from a professional roofer.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most common residential roofing material, typically last 20–25 years before needing replacement. If your roof is approaching or past this lifespan, have it evaluated to determine if full replacement is needed.

Leaks or Water Stains in Your Home

One of the most obvious signs of a roof issue is leaking. Stains on walls, insulation, and ceilings — or in your attic — usually indicate that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can lead to mold growth and roof deterioration.

Exposed Roof Decking Underneath Shingles

If you can see your roof decking or sheathing material underneath your shingles, it means those shingles are severely curling or losing their seal and need to be replaced. Shingles should lie flat to keep water from leaking into your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a safe ladder. Look for tears in the shingle surface or loss of protective granule coating. Storms that bring strong winds can cause surface damage over time. To keep your roof in good shape, replace any shingles that are missing or have open gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a barrier against the elements around chimneys, valleys, vents, and other areas that penetrate your roof. If this metal flashing is coming loose, cracked open, or worn down, it can allow leaks. Problems with roof flashing should be addressed promptly.

Sagging Roof Line

If you notice your roofline showing signs of sagging or unevenness, it could indicate a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not properly supported or replaced.
