How To Choose a Roofing Company

Roof installation is a large home improvement project that can cost upwards of twenty thousand dollars when all is said and done. It's crucial to research and find the most skilled and reliable roofing professional for the job. Here are some important factors to consider when choosing a roofing contractor.

• Responsiveness and communication: From estimate to project completion, your contractor should regularly communicate with you, answer all questions, and address any concerns.
• Warranties and guarantees: A reliable roofer will provide robust manufacturer warranties that cover shingles for 30+ years along with at least a 5-year workmanship warranty on labor. Be wary of shorter guarantees.
• Experience and credentials: Seek out providers that have been operating for at least 10 years. These companies' extensive experience and time in operation reflects consistent work, knowledgeable teams, and happy former customers. Confirm that a provider has appropriate licenses, bonds, and insurance before hiring. Also inquire 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. You can also request recent local references to learn more.
• Detailed written estimate: Legitimate roofing companies will provide a thorough written proposal. The proposal should detail the full project scope, materials needed, and total cost with no surprise charges. Avoid providers that offer unclear quotes, or ones that seem way too low or high.
• Roofing materials and products: Quality roofing materials from top brands are able to handle Portsmouth's weather and last for decades. Beware of contractors who offer extremely low-cost or generic products. Inspect shingle samples before deciding.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it protects your home in important ways. Look out for these common signals that your roof needs to be evaluated and repaired by 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 around 20–25 years before needing to be replaced. If your roof is nearing or past this lifespan, have it evaluated to determine if full replacement is needed.

Leaks or Water Stains in Your Home

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

Exposed Roof Decking Underneath Shingles

If you can see the roof deck boards underneath your shingles, it means those shingles are severely curling or losing their seal and need to be replaced. Shingles should lie flat to keep water from entering your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a safe ladder. Look for tears in the shingle surface or loss of protective granule coating. 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 are openly gaping.

Flashing Deterioration Around Roof Penetrations

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

Sagging Roof Line

If your roof sags or is uneven, get a roofer to evaluate it. These issues could indicate a structural problem. A sagging roof that's not given adequate structural reinforcement or full replacement will deteriorate more over time.
