How To Choose a Roofing Company

Installing a new roof is a major home renovation that might cost tens of thousands of dollars. It's essential to research thoroughly to find the best credentialed and most respected roofing company for the job. Here are some key factors to consider when picking a roofer.

• Detailed written estimate: Legitimate roofers will provide a thorough written estimate. The estimate should specify the full scope of the project, materials needed, and full price with no surprise charges. Avoid companies that provide unclear quotes, or ones that seem way too low or high.
• Responsiveness and communication: Your contractor should communicate consistently throughout, from the quote to the completion of the project. A representative should respond to questions quickly and resolve any worries while working.
• Experience and credentials: An established roofing provider that has been operating for over a decade demonstrates stability, experience, and a proven track record. Ensure the company is fully licensed, bonded, and insured before you hire them. Ask about any professional certifications relating your project, such as those from the National Roofing Contractors Association.
• References and reviews: Check companies thoroughly by checking their latest online reviews on Google, Yelp, or the Better Business Bureau (BBB) and looking for consistently good feedback over many years. Also request recent local references to find out more.
• Roofing materials and products: Quality roofing companies sell quality materials that can handle Waltham's weather and endure a long time. Be careful of contractors pushing extremely low-cost or generic options. Inspect shingle samples before committing.
• Warranties and guarantees: Reputable roofers provide robust guarantees from shingle manufacturers which protect shingles for over 30 years and labor guarantees for at least 5 years. Use caution with roofers offering shorter warranties.

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 inspected and repaired by a professional roofer.

Roof Age

The age and material of your roof are key factors. Asphalt shingles, the most common residential roofing material, typically last 20–25 years before needing replacement. If your roof is approaching or past this lifespan, get a professional inspection to determine if full replacement is needed.

Leaks or Water Stains in Your Home

Leaks are a definite sign that your roof needs repair. Stains on ceilings, walls, or insulation, or in your attic often signal that water is getting through damaged or worn shingles. Even small leaks need to be taken care of promptly, as they can result in mold and more damage over time.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing beneath 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 getting into your home.

Cracked, Broken, or Missing Shingles

Examine your shingles thoroughly from ground level or a sturdy ladder. Look for ones that are damaged or that no longer have their protective coating. Over time, storms can cause surface damage. To keep your roof in good condition, replace any missing shingles or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a weatherproof seal 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. Problems with roof flashing should be addressed promptly.

Sagging Roof Line

If your roof shows signs of sagging or unevenness, schedule a professional inspection. These issues could indicate a structural problem. A sagging roof that's not properly supported or fixed will deteriorate more over time.
