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 choosing a roofer.

• Detailed written estimate: Dependable roofers will provide a thorough written estimate. The proposal should detail the full scope of the project, materials required, and full price with no surprise charges. Avoid providers that offer unclear quotes, or ones that seem way too low or high.
• References and reviews: Vet companies by reviewing their most recent online feedback on sites such as Google, Yelp, or the Better Business Bureau (BBB). Look for a history of consistently positive reviews. You can also request recent local references to learn more about the customer experience.
• Responsiveness and communication: Your contractor should communicate consistently throughout, from the estimate to project completion. A representative should respond to questions quickly and address any issues while working.
• Roofing materials and products: Reputable manufacturers produce durable roofing materials that can withstand Rochester's weather for years. Avoid contractors pushing low-cost or generic products. Check out shingle samples before making a decision.
• Warranties and guarantees: Reputable roofing companies offer robust warranties that cover your roof. Look for guarantees on shingles lasting 30+ years, plus at least a 5-year guarantee on labor. Avoid companies that have shorter warranties.
• Experience and credentials: An established roofing provider that has many years of experience in business demonstrates years of expertise, satisfied customers, and consistent quality work. Ensure the company is fully licensed, bonded, and insured before hiring. Ask about any professional certifications relating your project, such as those from the National Roofing Contractors Association.

Signs Your Roof Needs Repair or Replacement

Though it likely doesn't cross homeowners' minds daily, your roof plays a key role in protecting your home. Watch for these common signs that your roof may need an inspection and repairs from a professional roofer.

Roof Age

Your roof's age and material are both important. The most popular residential roofing material is asphalt shingles, which typically last 20–25 years before needing to be replaced. Have your roof evaluated if it’s reaching this age to determine if a full replacement is needed.

Leaks or Water Stains in Your Home

Leaks are a common sign of roof issues. Water leaking through worn or damage shingles often leads to water stains on walls, insulation, and ceilings, or in your attic. Don't dismiss even small leaks, as they can still cause mold and other damage.

Exposed Roof Decking Underneath Shingles

If you can see roof deck boards or sheathing under shingles, it means that those shingles are curling or losing their seal. This means the shingles likely need replacement. Shingles should lie flat to stop water from entering your home.

Cracked, Broken, or Missing Shingles

Carefully inspect your shingles from the ground or a steady ladder. Look for any shingles that have cracked or have lost their protective granule coating. Over time, environmental factors like storms can cause surface damage. To keep your roof in good shape, you should replace any shingles that are no longer attached properly or that have gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a watertight seal around valleys, chimneys, vents, and other areas where water can leak into your home. Deteriorated, cracked, or peeling flashing can allow leaks. We recommend promptly resolving any flashing issues that come up.

Sagging Roof Line

If your roof shows signs of sagging or unevenness, it's time to call a professional roofer. These issues could indicate a structural problem. A sagging roof that's not properly supported or fixed will continue worsening over time.
