How To Choose a Roofing Company

A new roof installation is a major home renovation that can run over twenty thousand dollars total. It's essential to research and find the most qualified and reputable roofing company for the job. Here are the top things to evaluate when choosing a roofer.

• Responsiveness and communication: From quote to project completion, the company should maintain ongoing communication with you, answer all questions, and resolve any concerns.
• Experience and credentials: An established roofing provider 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 thoroughly by checking online review sites like Google, Yelp, or the Better Business Bureau (BBB) for years of consistently positive feedback. You can also request recent local references to learn more.
• Detailed written estimate: Quality roofers will provide detailed written proposals. These proposals should outline the full scope of the project, materials needed, and total cost without hidden fees. Avoid vague bids or ones that seem much too high or low.
• Warranties and guarantees: The best roofers provide strong guarantees from the shingle makers covering materials for 30+ years, together with at least a 5-year labor warranty. Avoid companies with shorter warranty periods.
• Roofing materials and products: Reputable manufacturers produce durable roofing materials that can endure Los Altos Hills' weather for years. Steer clear of contractors pushing low-cost or generic products. Review shingle samples before making a decision.

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. Look out 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, typically 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 most obvious signs of a roof problem is leaking. Stains on ceilings, walls, and insulation — or in your attic — usually indicate 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

Seeing roof deck boards or sheathing under your shingles is a sign that those shingles are severely curling or losing their seal. This means the shingles likely need replacement. Shingles should lie flat to stop water from leaking into your home.

Cracked, Broken, or Missing Shingles

Carefully examine your shingles from the ground or a safe ladder. Look for any shingles that have cracked or are missing granules. Over time, environmental factors like storms can cause surface damage. To keep your roof in good repair, you should replace any dislodged or gaping shingles.

Flashing Deterioration Around Roof Penetrations

Roof flashing makes a watertight seal around chimneys, vents, valleys, and other areas where water can penetrate your roof. Deteriorated, cracked, or peeling flashing can allow leaks. We recommend promptly resolving any problems with the roof flashing that come up.

Sagging Roof Line

If you notice your roofline showing signs of sagging or unevenness, 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 given proper reinforcement or replaced entirely.
