How To Choose a Roofing Company

A new roof installation is a major home renovation that can cost tens of thousands of dollars. It's crucial to research and find a highly reviewed and recommended roofing company for the job. Here are the top things to evaluate when choosing a roofer.

• Experience and credentials: Companies operating for over a decade have a proven history and track record of quality work and satisfied customers. Make sure any provider you consider is properly licensed, bonded, and insured. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• 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. Requesting local references is another great way to learn more about the customer experience.
• Responsiveness and communication: From quote to project completion, your roofer should regularly communicate with you, answer all questions, and handle any concerns.
• Warranties and guarantees: Reputable roofing companies offer robust warranties that protect your roof. Look for guarantees on shingles lasting 30+ years, plus at least a 5-year guarantee on labor. Stay away from companies that have shorter warranties.
• Roofing materials and products: Quality roofing companies sell quality materials that can handle Raritan's weather and endure a long time. Be careful of contractors pushing extremely inexpensive or generic options. Review shingle samples before committing.
• Detailed written estimate: Reputable roofing companies will give you a comprehensive written estimate that outlines the full scope of the work, specific materials, and total cost without hidden fees. Avoid vague quotes or ones that seem dramatically low or high.

Signs Your Roof Needs Repair or Replacement

While the average homeowner may not spend a lot of time thinking about their roof, a roof plays a vital role in keeping a home safe and secure. Be on the lookout for these signs that your roof might need professional attention.

Roof Age

Your roof's age and material are key factors. The most popular residential roofing material is asphalt shingles, which generally last around 20–25 years before needing to be replaced. Have your roof evaluated if it’s approaching this age to determine if a 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 mean that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can encourage 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 severely curling or losing their seal and need to be replaced. Shingles should lie flat to prevent water from leaking into your house.

Cracked, Broken, or Missing Shingles

Carefully inspect your shingles from the ground or a safely-placed ladder. Look for any shingles that have cracks 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 provides a weatherproof seal around valleys, vents, chimneys, and other areas that penetrate the roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Any issues with flashing should be addressed promptly.

Sagging Roof Line

If your roof sags or is uneven, schedule a professional inspection. These issues could indicate a structural problem. A sagging roof that's not given adequate structural reinforcement or full replacement will worsen over time.
