How To Choose a Roofing Company

A new roof installation is a large home renovation that can run tens of thousands of dollars. It's crucial to research and find a highly reviewed and recommended roofing company for the job. Here are the top things to evaluate when choosing a roofer.

• Detailed written estimate: Trustworthy roofing companies will provide detailed written proposals. These proposals should outline the full scope of the project, materials required, and total cost without hidden fees. Avoid vague bids or quotes that seem much too low or high.
• References and reviews: Vet companies by reviewing their most recent online feedback on sites such as Google, Yelp, or the Better Business Bureau (BBB). Look for a track record of consistently good feedback. You can also request recent local references to learn more about the customer experience.
• Responsiveness and communication: From quote to project completion, your contractor should keep in consistent contact with you, answer all questions, and resolve any concerns.
• Warranties and guarantees: A reliable roofer will provide robust manufacturer warranties that cover shingles for 30+ years along with at least a 5-year guarantee on workmanship. Be wary of shorter guarantees.
• Experience and credentials: Companies that have been in business for over 10 years show stability and expertise. Before hiring, make sure the company has current licenses, bonding, and insurance. 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 withstand San Marino's weather for years. Avoid contractors offering low-cost or generic products. Inspect 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. Be attentive to these common signs that your roof may be in need of professional inspection and repair.

Roof Age

Your roof's age and material are both important. The most popular residential roofing material is asphalt shingles, which normally last 20–25 years before requiring replacement. Have your roof evaluated if it’s reaching this age to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

One of the most obvious signs of a roof issue is leaking. Stains on walls, insulation, and ceilings — or in your attic — usually mean 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

If you can see roof decking or sheathing underneath your shingles, it means those shingles are severely curling or losing their seal, and replacement is required. Shingles should lie flat to prevent water from entering your home.

Cracked, Broken, or Missing Shingles

Inspect your shingles thoroughly from ground level or a safe ladder. Look for ones that have cracks or that no longer have their protective coating. Over time, storms can cause surface damage. To keep your roof in good shape, replace any missing shingles or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a weatherproof seal around vents, valleys, chimneys, and other areas that penetrate your roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Any issues with flashing should be addressed promptly.

Sagging Roof Line

An uneven roofline may mean there's a structural issue that requires professional evaluation. Without properly addressing and resolving the issue, a sagging roof will worsen over time.
