How To Choose a Roofing Company

Roof installation is a large 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 skilled and reliable roofing professional for the job. Here are some important factors to consider when choosing a roofing contractor.

• Roofing materials and products: Leading manufacturers produce durable roofing materials that can endure Dover's weather for years. Avoid contractors pushing low-cost or generic products. Inspect shingle samples before making a decision.
• References and reviews: Check companies thoroughly by verifying recent reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for consistently good feedback over many years. You can ask for recent local references to learn more.
• Detailed written estimate: Dependable roofing companies will provide a thorough written proposal. The estimate should detail the full project scope, materials needed, and full price with no surprise charges. Avoid companies that provide unclear quotes, or ones that seem way too high or low.
• Responsiveness and communication: From estimate to project completion, your contractor should regularly communicate with you, respond to all questions, and address any concerns.
• 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 guarantees.
• Experience and credentials: Look for companies that have been operating for a decade or more. These companies' longevity and years in business reflects stability, expertise, and satisfied past clients. Ensure a provider has appropriate licenses, bonds, and insurance before hiring. Also ask about professional certifications, such as those from the National Roofing Contractors Association.

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. Be aware of these common signals that your roof needs to be checked and repaired by a professional roofer.

Roof Age

Your roof's age and material are both important. The most popular residential roofing material is asphalt shingles, which normally 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 typical sign of roof issues. Water leaking through worn or damage shingles often leads to water stains on walls, ceilings, and insulation, 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

If you can see the roof decking or sheathing material underneath your shingles, it means those shingles are severely curling or losing their seal and need replacement. Shingles should lie flat to prevent water from getting into your home.

Cracked, Broken, or Missing Shingles

Check your shingles thoroughly from ground level or a sturdy ladder. Look for ones that have cracks or that are missing granules. Over time, storms can cause surface damage. To keep your roof in good shape, replace any missing shingles or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing protects vents, valleys, chimneys, and other areas that pass through the roof. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any flashing problems fixed right away.

Sagging Roof Line

If your roof sags or is uneven, it's time to call a professional roofer. These issues could signal a structural problem. A sagging roof that's not properly supported or fixed will worsen over time.
