How To Choose a Roofing Company

Roof installation is a major home improvement project that can cost tens of thousands of dollars. It’s crucial to do your research and find the top-rated company for the job. Here are the key factors to consider when choosing a roofer.

• Responsiveness and communication: From the time you get a quote to project completion, a roofing contractor should maintain regular contact. A representative should answer questions and resolve any issues during the project.
• Roofing materials and products: Leading manufacturers produce durable roofing materials that can withstand Los Altos' weather for years. Avoid contractors pushing low-cost or generic products. Inspect shingle samples before making a decision.
• Experience and credentials: Seek out providers that have been operating for at least 10 years. These companies' longevity and years in business reflects stability, expertise, and satisfied past clients. Ensure a provider has appropriate licenses, bonds, and insurance before committing. Also ask about professional certifications, such as those from the National Roofing Contractors Association.
• Warranties and guarantees: Reputable roofing companies provide strong guarantees that cover your roof. Look for guarantees on shingles lasting 30+ years, plus at least a 5-year guarantee on labor. Avoid companies that have shorter warranties.
• References and reviews: Research companies carefully by examining their Google, Yelp, or Better Business Bureau (BBB) profiles to look for years of consistently positive feedback. Also ask for recent local references.
• Detailed written estimate: Trustworthy roofing companies will provide detailed written proposals. These bids should outline the full scope of the project, materials needed, and total cost with no hidden fees. Avoid vague bids or quotes that seem much too high or low.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof daily, 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 important. 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, get a professional inspection to determine if 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 ignore even small leaks, as leaks of any size can cause mold and other issues.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing beneath your shingles, it means those shingles are curling substantially or losing their seal, and replacement is required. Shingles should lie flat to prevent water from leaking into your house.

Cracked, Broken, or Missing Shingles

Examine your roof shingles from the ground or a safe ladder. Look for tears in the shingle surface or missing granules. Storms that bring strong winds can cause surface damage over time. To keep your roof in good shape, replace any shingles that have come loose or have open gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing seals off chimneys, vents, valleys, and other areas that pass through the roof. If the metal flashing is damaged, coming loose, or deteriorated, it can leak. Have any issues with roof flashing fixed right away.

Sagging Roof Line

If you notice your roofline sagging or sloping unevenly, it could signal 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.
