How To Choose a Roofing Company

A new roof installation is a major home renovation that can run over twenty thousand dollars total. It's essential to research and find a highly reviewed and recommended roofing company for the job. Here are the top things to evaluate when selecting a roofer.

• Roofing materials and products: Reputable manufacturers produce durable roofing materials that can withstand Mahwah's weather for years. Avoid contractors offering low-cost or generic products. Inspect shingle samples before making a decision.
• 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.
• Experience and credentials: Companies operating for over a decade have a proven history and track record of quality work and satisfied customers. Only consider companies that are 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 contractor should regularly communicate with you, answer all questions, and address any concerns.
• Detailed written estimate: Reputable roofers will give you a comprehensive written estimate that outlines the full scope of the work, specific materials, and total cost with no hidden fees. Avoid vague quotes or ones that seem dramatically high or low.
• References and reviews: Vet companies by examining their latest customer reviews on Google, Yelp, or the Better Business Bureau (BBB) to look for a history of consistently positive reviews. Requesting local references is another great way to learn more about the customer experience.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every day, it provides critical protections for your home. Be attentive for these common signs that your roof may need inspection and repairs from a professional roofer.

Roof Age

The age and material of your roof are key factors. Asphalt shingles, the most popular residential roofing material, typically last 20–25 years before needing to be replaced. If your roof is nearing or past this lifespan, get a professional inspection to determine if full replacement is needed.

Leaks or Water Stains in Your Home

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

Exposed Roof Decking Underneath Shingles

Visible roof decking or sheathing under your shingles is a sign that those shingles are severely curling or losing their seal. This means it's time for replacement. Shingles need to lie flat to stop water from entering 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 keep your roof in good shape, replace any shingles that are no longer securely attached or have open gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing seals off valleys, chimneys, vents, and other areas that pass through the roof. If the metal flashing is damaged, coming loose, or deteriorated, it can leak. Have any flashing problems fixed right away.

Sagging Roof Line

If your roof shows signs of sagging or unevenness, schedule a professional inspection. These issues could indicate a structural problem. A sagging roof that's not properly supported or fixed will worsen over time.
