How To Choose a Roofing Company

A new roof installation is a large home renovation that can cost over twenty thousand dollars total. It's crucial to research and find a highly reviewed and recommended roofing company for the job. Here are the top things to evaluate when choosing a roofer.

• Roofing materials and products: Quality roofing materials from leading manufacturers are able to withstand Alameda's weather and hold up for decades. Beware of contractors who push extremely low-cost materials or generic products. Check out shingle samples before making a decision.
• Warranties and guarantees: Reputable roofers provide strong manufacturer warranties covering shingles for 30+ years and workmanship warranties for five or more years. Use caution with roofers offering shorter warranties.
• Experience and credentials: An established roofing company 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 you hire them. Ask about any professional certifications that relate to your project, such as those from the National Roofing Contractors Association.
• References and reviews: Vet companies by examining their latest customer reviews on Google, Yelp, or the Better Business Bureau (BBB) to look for a history of consistently good feedback. Requesting local references is another great way to learn more about the customer experience.
• Responsiveness and communication: From quote to project completion, your roofer should regularly communicate with you, respond to all questions, and address any concerns.
• Detailed written estimate: Trustworthy roofers will provide a comprehensive estimate in writing that outlines the full scope of the work, materials requirements, and total cost without hidden fees. Avoid vague bids or quotes that seem dramatically low or high.

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. Be attentive for these common signs that your roof may need inspection and repairs from a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, generally last about 20 to 25 years before needing replacement. Schedule a professional inspection if your roof is nearing or past this lifespan to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

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

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 to be replaced. Shingles should lie flat to keep water from getting into your home.

Cracked, Broken, or Missing Shingles

Examine your roof shingles from the ground or a steady ladder. Look for signs of damage or loss of protective granule coating. Storms that bring strong winds can cause surface damage over time. To maintain your roof, replace any shingles that are no longer securely attached or are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing protects vents, chimneys, valleys, and other areas that penetrate your roofing system. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any issues with roof flashing fixed right away.

Sagging Roof Line

If you notice your roofline displaying signs of sagging or uneven slopes, it could be a sign of a problem with the structure that requires further inspection by a roofer. A sagging roof deck will worsen over time if not properly supported or replaced.
