How To Choose a Roofing Company

Roof installation is a large home improvement project that can cost a significant amount. It’s essential to do your research and find the top-rated company for the job. Here are the key factors to consider when choosing a roofer.

• Detailed written estimate: Trustworthy roofing companies will provide a comprehensive estimate in writing that outlines the scope of the work, specific materials, and total cost with no hidden fees. Avoid vague bids or quotes that seem dramatically high or low.
• Responsiveness and communication: From the time you get a quote to project completion, your roofer should keep you regularly updated. A representative should address questions and resolve any issues during the project.
• References and reviews: Research companies carefully by reviewing their profiles on review sites such as Google, Yelp, or the Better Business Bureau (BBB) and looking for years of consistently good feedback. You can also request recent local references.
• Roofing materials and products: Reputable manufacturers produce durable roofing materials that can withstand Rosemead's weather for years. Steer clear of contractors offering low-cost or generic products. Review shingle samples before making a decision.
• 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. Watch out for companies with less robust coverage.
• Experience and credentials: An established roofing provider that has many years of experience in business demonstrates stability, experience, and a proven track record. Ensure the company is fully licensed, bonded, and insured before hiring. Ask about any professional certifications that relate to your project, such as those from the National Roofing Contractors Association.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof on a daily basis, it plays a vital protective role for your home. Remain alert for these common signs that your roof may need inspection and repairs from a professional roofer.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most common roofing material for homes, usually last about 20–25 years. If your roof is nearing or past this lifespan, have it inspected to see if it needs to be replaced.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof issue is leaking. Stains on ceilings, walls, and insulation — or in your attic — usually mean that water is seeping through worn or damaged shingles. Don't ignore small leaks, because even these can lead to mold growth and roof deterioration.

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 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 signs of damage or loss of protective granule coating. Storms that bring strong winds can cause surface damage over time. To maintain your roof, replace any shingles that are no longer securely attached or have open gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing seals off chimneys, valleys, vents, and other areas that pass through the roof. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any flashing problems fixed right away.

Sagging Roof Line

If you notice your roofline displaying signs of sagging or uneven slopes, it could indicate 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.
