How To Choose a Roofing Company

Roof installation is a major home improvement project that can cost a significant amount. It’s crucial to do your research and find the most qualified company for the job. Here are the key factors to consider when selecting a roofer.

• Detailed written estimate: Reputable roofing companies will give you a comprehensive estimate in writing that outlines the full scope of the work, materials requirements, and total cost with no hidden fees. Avoid vague bids or quotes that seem dramatically low or high.
• 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. Also ask for recent local references.
• Roofing materials and products: Quality roofing materials from leading manufacturers are able to withstand Knoxville's weather and last for decades. Beware of contractors who offer extremely low-cost or generic products. Check out shingle samples before deciding.
• Experience and credentials: Companies operating for over a decade have a proven history and track record of expert service and happy clients. Make sure any provider you consider is licensed, bonded, and insured. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• Responsiveness and communication: From estimate to project completion, your roofer should maintain ongoing communication with you, respond to all questions, and handle any concerns.
• Warranties and guarantees: A reliable roofer will provide strong guarantees from the manufacturer which protect shingles for over 30 years along with at least a 5-year workmanship warranty on labor. Be wary of shorter warranty periods.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof daily, but it protects your home in important ways. Be aware of these common signals that your roof needs to be evaluated and repaired by a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, typically last about 20 to 25 years before needing to be replaced. Schedule a professional inspection if your roof is nearing or past this lifespan to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

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

Exposed Roof Decking Underneath Shingles

If you can see roof sheathing or decking under shingles, it indicates that those shingles are considerably curling or losing their seal. This means it's time for replacement. Shingles need to lie flat to prevent water from entering your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a steady ladder. Look for tears in the shingle surface or missing granules. Storms that bring strong winds can cause surface damage over time. To maintain your roof, replace any shingles that are missing or have open gaps.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof creates a watertight barrier around chimneys, valleys, vents, and other areas where water can leak in. If the flashing is developing cracks, peeling away, or deteriorating over time, it may leak. Promptly address any flashing issues.

Sagging Roof Line

If you notice your roofline displaying signs of sagging or uneven slopes, it could signal a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not reinforced or replaced.
