How To Choose a Roofing Company

Installing a new roof is a big home improvement project that can cost an amount in the tens of thousands range in the end. It's essential to research and find the most qualified and reputable residential roofing company for the job. Here are some key considerations when choosing a roofing contractor.

• 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.
• Roofing materials and products: Quality roofing materials from top brands can withstand Derry's weather and endure decades. Watch out for contractors pushing cheap or generic materials. Inspect shingle samples before deciding.
• Experience and credentials: Companies operating for over a decade demonstrate years of experience on top of quality work and satisfied customers. Make sure any provider you consider is properly licensed, bonded, and insured. Ask about professional certifications, such as those from the National Roofing Contractors Association.
• 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.
• Detailed written estimate: Trustworthy roofing companies 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.
• Responsiveness and communication: From the time you get a quote to when the project is complete, your roofer should keep you regularly updated. A representative should respond to questions and deal with any issues during the project.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every day, it plays a vital protective role for your home. Remain alert for these common signs that your roof may need professional inspection and repair.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most common roofing material for homes, normally last about 20 to 25 years. If your roof is nearing or past this lifespan, schedule an inspection to see if complete replacement is necessary.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof problem is leaking. Stains on insulation, walls, and ceilings — or in your attic — usually mean that water is seeping through worn or damaged shingles. Don't ignore small leaks, because even these can lead to mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

If you can see roof sheathing or decking under shingles, it indicates that those shingles are considerably curling or losing their seal. This means the shingles likely need replacement. Shingles need to lie flat to prevent water from getting into your home.

Cracked, Broken, or Missing Shingles

Carefully inspect your shingles from the ground or a safely-placed 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 missing shingles or ones with 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 coming loose, cracked open, or worn down, it can allow leaks. Any issues with flashing should be addressed promptly.

Sagging Roof Line

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