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 the most qualified and reputable roofing company for the job. Here are some important considerations for selecting a roofer.

• Detailed written estimate: Trustworthy roofing companies will give you a comprehensive written quote. This quote should outline the complete work scope, materials, and total price without hidden costs. Steer clear of unclear quotes, or ones that seem much too high or low.
• 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 guarantee on workmanship. Be wary of shorter warranty periods.
• Experience and credentials: An established roofing provider that has been operating for over a decade demonstrates years of expertise, satisfied customers, and consistent quality work. Ensure the company is fully licensed, bonded, and insured before hiring. Inquire about any professional certifications relating your project, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Quality roofing materials from top brands are able to withstand Denville's weather and last for decades. Beware of contractors who push extremely low-cost materials or generic products. Check out shingle samples before making a decision.
• 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.
• Responsiveness and communication: From the time you get a quote to project completion, a roofing contractor should keep you regularly updated. A representative should respond to questions and resolve any issues during the project.

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 be in need of professional inspection and repair.

Roof Age

Your roof's age and material are both important. The most common residential roofing material is asphalt shingles, which typically last about 20 to 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 insulation, ceilings, and walls, or in your attic. Don't neglect even small leaks, as they can still lead to mold and other damage.

Exposed Roof Decking Underneath Shingles

Seeing roof deck boards or sheathing under your shingles indicates 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

Carefully inspect your shingles from the ground or a steady 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 condition, you should replace any shingles that are no longer attached properly or that have gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a barrier against the elements around vents, chimneys, valleys, 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. Problems with roof flashing should be addressed promptly.

Sagging Roof Line

If you notice your roofline showing signs of sagging or unevenness, it could indicate a problem with the structure that requires further inspection by a roofer. A sagging roof deck will worsen over time if not given proper reinforcement or replaced entirely.
