How To Choose a Roofing Company

Roof installation is a large 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 some important considerations for selecting a roofer.

• References and reviews: Check companies thoroughly by checking their latest online reviews on Google, Yelp, or the Better Business Bureau (BBB) and looking for a history of consistently good feedback over many years. Also request recent local references to find out more.
• Experience and credentials: Companies operating for over a decade demonstrate years of experience on top of quality work and satisfied customers. Make sure any provider you consider is licensed, bonded, and insured. Ask about professional certifications, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Reputable manufacturers produce durable roofing materials that can endure California's weather for years. Steer clear of contractors offering low-cost or generic products. Inspect shingle samples before making a decision.
• Warranties and guarantees: Reputable roofing companies offer robust warranties that protect your roof. Look for guarantees on shingles lasting 30+ years and at least a 5-year labor guarantee. Avoid companies that have less coverage than that.
• Responsiveness and communication: From the time you get a quote to when the project is complete, your contractor should communicate consistently. A representative should address questions and deal with any issues during the project.
• Detailed written estimate: Trustworthy roofing companies will offer a comprehensive written estimate. This quote should outline the complete work plan, materials required, and total price without hidden fees. Steer clear of unclear bids, or ones that seem much too high or low.

Signs Your Roof Needs Repair or Replacement

While most homeowners don't think about their roof every day, it plays a key role in protecting your home. Watch for these common signs that your roof may need an 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 approaching or past this lifespan to determine if full replacement is needed.

Leaks or Water Stains in Your Home

One of the most obvious signs of a roof issue is leaking. Stains on ceilings, insulation, and walls — or in your attic — usually indicate that water is seeping through worn or damaged shingles. Don't ignore small leaks, because even these can lead to mold growth and roof 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 roof shingles from the ground or a safe ladder. Look for signs of damage 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 creates a watertight seal around valleys, chimneys, vents, and other areas where water can leak into your home. Peeling, cracked, or deteriorated flashing can allow leaks. We recommend quickly addressing any problems with the roof flashing that come up.

Sagging Roof Line

If you notice your roofline sagging or sloping unevenly, it could indicate a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not properly supported or replaced.
