How To Choose a Roofing Company

Roof installation is a big home improvement project that can cost an amount in the tens of thousands range in the end. It's crucial to research and find a top quality and trusted local roofing contractor for the job. Here are the key factors to consider when choosing a roofing contractor.

• Responsiveness and communication: From estimate to project completion, your contractor should maintain ongoing communication with you, answer all questions, and handle any concerns.
• 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 indicate that water is seeping through deteriorating shingles. Don't ignore small leaks, because even these can lead to mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

Visible roof decking or sheathing under your shingles is a sign that those shingles are severely curling or losing their seal. This means it's time for replacement. Shingles need to lie flat to stop water from leaking into your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a steady 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 protects valleys, vents, chimneys, and other areas that pass through the roof. If the metal flashing is damaged, coming loose, or deteriorated, it can leak. Have any flashing problems fixed right away.

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.
