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 best company for the job. Here are the key factors to consider when selecting a roofer.

• Detailed written estimate: Dependable roofing companies will provide a thorough written quote. The quote should specify the full project scope, materials required, and total cost with no surprise charges. Avoid providers that offer unclear quotes, or ones that seem way too low or high.
• 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 that relate to your project, such as those from the National Roofing Contractors Association.
• References and reviews: Vet companies thoroughly by verifying on review sites such as Google, Yelp, or the Better Business Bureau (BBB) that they have consistently positive feedback. You can also request recent local references to learn more.
• Responsiveness and communication: From the time you get a quote to project completion, your contractor should keep you regularly updated. A representative should respond to questions and resolve any issues during the project.
• 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. Be cautious of companies with less robust coverage.
• Roofing materials and products: Quality roofing materials from top brands can handle Fontana's weather and endure decades. Avoid contractors offering cheap or generic materials. Check shingle samples before deciding.

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 be in need of professional inspection and repair.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, typically last around 20–25 years before needing to be replaced. 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 clearest signs of a roof problem is leaking. Stains on ceilings, walls, and insulation — 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 sheathing or decking under shingles, it shows that those shingles are considerably curling or losing their seal. This means the shingles likely need replacement. Shingles need to lie flat to stop water from getting into your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a steady ladder. Look for cracking or loss of protective granule coating. 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 chimneys, vents, valleys, 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 sags or is uneven, get a roofer to evaluate it. These issues could indicate a structural problem. A sagging roof that's not properly supported or fixed will deteriorate more over time.
