How To Choose a Roofing Company

Installing a new roof is a big home renovation that might cost tens of thousands of dollars. It's crucial to research extensively to find the best credentialed and most respected roofing company for the job. Here are some important considerations when choosing a roofer.

• References and reviews: Vet companies thoroughly by looking on Google, Yelp, or the Better Business Bureau (BBB) to see that they have a history of consistently positive feedback. You can also request recent local references to learn more.
• Warranties and guarantees: Reputable roofing companies offer robust warranties that cover your roof. Look for guarantees on shingles lasting 30+ years and at least a 5-year labor guarantee. Be wary of companies that have shorter warranties.
• Detailed written estimate: Reputable roofers will offer a comprehensive written estimate that outlines the full scope of the work, materials requirements, and total cost with no hidden fees. Avoid vague quotes or ones that seem dramatically low or high.
• Roofing materials and products: Leading manufacturers produce durable roofing materials that can withstand Altadena's weather for years. Steer clear of contractors pushing low-cost or generic products. Inspect shingle samples before making a decision.
• Responsiveness and communication: Your contractor should maintain regular contact throughout, from the estimate to project completion. A representative should respond to questions quickly and resolve any concerns while working.
• Experience and credentials: An established roofing provider that has many years of experience in business demonstrates years of expertise, satisfied customers, and consistent quality work. Ensure the company is fully licensed, bonded, and insured before hiring. Ask about any professional certifications relating your project, such as those from the National Roofing Contractors Association.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it protects your home in important ways. Be aware of these common signals that your roof needs to be checked and repaired by a professional roofer.

Roof Age

Your roof's age and material are key factors. The most popular residential roofing material is asphalt shingles, which normally last about 20 to 25 years before needing to be replaced. Have your roof evaluated if it’s approaching this age to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

Leaks are a definite sign that your roof requires repairs. Stains on insulation, ceilings, or walls, or in your attic often signal that water is getting through damaged or worn shingles. Even small leaks should be taken care of right away, as they can lead to mold and more deterioration over time.

Exposed Roof Decking Underneath Shingles

If you can see roof deck boards or sheathing under shingles, it means that those shingles are considerably curling or losing their seal. This means the shingles likely need replacement. Shingles should lie flat to prevent water from entering your home.

Cracked, Broken, or Missing Shingles

Examine your shingles thoroughly from ground level or a steady ladder. Look for ones that are damaged or that no longer have their protective coating. Over time, storms can cause surface damage. To keep your roof in good condition, replace any shingles that are no longer attached properly or have gaping holes.

Flashing Deterioration Around Roof Penetrations

Roof flashing protects vents, chimneys, valleys, and other areas that penetrate your roofing system. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any issues with roof flashing fixed right away.

Sagging Roof Line

An uneven roofline may be a sign of a structural issue that requires professional evaluation. Without taking steps to fix or replace it, a sagging roof will get worse over time.
