How To Choose a Roofing Company

Installing a new roof is a big home improvement project that can cost tens of thousands of dollars in the end. It's crucial to research and find a top quality and trusted local roofing contractor for the job. Here are the key factors to consider when choosing a roofing contractor.

• Responsiveness and communication: Your contractor should communicate consistently throughout, from the estimate to the completion of the project. A representative should respond to questions in a timely manner and resolve any issues while working.
• Warranties and guarantees: The best roofers provide robust manufacturer warranties on shingles lasting over 30 years, together with at least a 5-year labor guarantee. Be cautious of companies with shorter warranty periods.
• Experience and credentials: Seek out providers that have been operating for a decade or more. These companies' longevity and years in business reflects stability, expertise, and satisfied past clients. Confirm that a provider has appropriate licenses, bonds, and insurance before committing. Also inquire about professional certifications, such as those from the National Roofing Contractors Association.
• Detailed written estimate: Reputable roofers will provide detailed written bids. These estimates should outline the full project scope, materials needed, and total cost without hidden fees. Avoid vague bids or ones that seem much too high or low.
• Roofing materials and products: Quality roofing materials from top brands are able to withstand Lexington's weather and last for decades. Beware of contractors who push extremely low-cost or generic products. Inspect shingle samples before making a decision.
• References and reviews: Vet companies thoroughly by verifying on review sites such as Google, Yelp, or the Better Business Bureau (BBB) that they have consistently positive feedback. Request recent local references from the company to learn more.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, 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. The most common residential roofing material is asphalt shingles, which normally last around 20–25 years before requiring replacement. Schedule an inspection if your roof is approaching this age to determine if a full replacement is needed.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof problem is leaking. Stains on walls, ceilings, and insulation — or in your attic — usually mean that water is seeping through deteriorating 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 roof decking or sheathing visible under your shingles, it means those shingles are curling substantially or losing their seal and need to be replaced. Shingles should lie flat to keep water from getting into your home.

Cracked, Broken, or Missing Shingles

Check 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 have come loose or have open gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a weatherproof seal around valleys, chimneys, 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

An uneven roofline may be a sign of a structural issue that requires professional attention. Without fixing or replacing it, a sagging roof will worsen over time.
