How To Choose a Roofing Company

Roof installation is a large home improvement project that can cost tens of thousands of dollars. It’s essential to do your research and find the best company for the job. Here are some important considerations for choosing a roofer.

• Responsiveness and communication: From the time you get a quote to when the project is complete, the company should maintain regular contact. A representative should address questions and handle any issues during the project.
• Warranties and guarantees: Reputable roofing companies provide strong guarantees that cover your roof. Look for coverage on shingles lasting 30+ years, plus at least a 5-year guarantee on labor. Avoid companies that have shorter warranties.
• Roofing materials and products: Leading manufacturers produce durable roofing materials that can endure Berkeley's weather for years. Steer clear of contractors offering low-cost or generic products. Review shingle samples before making a decision.
• Detailed written estimate: Trustworthy roofers will provide detailed written proposals. These bids should outline the full scope of the project, materials required, and total cost with no hidden fees. Avoid vague quotes or ones that seem much too high or low.
• Experience and credentials: Providers with a decade or more of experience show consistent quality and customer satisfaction. Before hiring, make sure the company has current licenses, bonding, and insurance. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• References and reviews: Research companies carefully by checking reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for years of consistently good feedback. Also ask for recent local references.

Signs Your Roof Needs Repair or Replacement

Though it likely doesn't cross homeowners' minds daily, your roof plays a key role in protecting your home. Look out for these common signs that your roof may need an inspection and repairs from 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 about 20 to 25 years before needing replacement. If your roof is approaching or past this lifespan, have it evaluated 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 mean that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can encourage mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

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

Cracked, Broken, or Missing Shingles

Examine your shingles closely from a steady ladder or while on the ground. Look for shingles that have cracked or are missing granules. Storms can cause roof damage over time. To keep your roof in good shape, replace any missing shingles, or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof seals off valleys, chimneys, vents, and other areas where water can leak in. If the flashing is becoming damaged, loose, or worn down, it may leak. Promptly take care of any flashing issues.

Sagging Roof Line

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