How To Choose a Roofing Company

Installing a new roof is a major home renovation that might cost tens of thousands of dollars when finished. It's essential to research in depth to find the most qualified and trustworthy roofing company for the job. Here are some key factors to consider when choosing a roofer.

• Detailed written estimate: Quality roofing companies will provide a thorough written proposal. 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 high or low.
• Warranties and guarantees: Reputable roofing companies offer robust warranties that cover your roof. Look for guarantees on shingles lasting 30+ years, plus at least a 5-year guarantee on labor. Stay away from companies that have less coverage than that.
• Experience and credentials: Seek out providers that have been operating for at least 10 years. These companies' longevity and years in business reflects consistent work, knowledgeable teams, and happy former customers. Confirm that a provider has appropriate licenses, bonds, and insurance before hiring. Also ask about professional certifications, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Quality roofing materials from top brands can withstand Signal Hill's weather and last years. Watch out for contractors pushing cheap or generic materials. Review shingle samples before deciding.
• Responsiveness and communication: From quote to project completion, the company should maintain ongoing communication with you, respond to all questions, and resolve any concerns.
• References and reviews: Vet companies by checking the latest online reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for a history of consistently positive reviews. Requesting local references is another great way to learn more about the customer experience.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every single day, a roof plays an important role in keeping a home safe and secure. Be on the lookout for these signs that your roof might need professional attention.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most popular roofing material for homes, normally last about around 20–25 years. If your roof is approaching or past this lifespan, schedule an inspection to see if complete replacement is necessary.

Leaks or Water Stains in Your Home

One of the clearest signs of roof trouble is water leaks. Stains on your insulation, ceilings, or walls, or in your attic are often a sign of water seeping through damaged or worn shingles. Even small leaks should be fixed promptly, as they can facilitate mold growth and further damage your roof.

Exposed Roof Decking Underneath Shingles

If you can see roof deck boards or sheathing under shingles, it shows that those shingles are curling or losing their seal. This means it's time for replacement. Shingles need to lie flat to stop water from leaking into your home.

Cracked, Broken, or Missing Shingles

Examine your shingles closely from a sturdy ladder or while on the ground. Look for shingles that have cracked or are missing granules. Storms can cause roof damage over time. To keep your roof in good shape, replace any shingles that have become detached or have gaping holes.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof seals off valleys, vents, chimneys, and other areas where water can leak in. If the flashing is becoming damaged, loose, or worn down, it may leak. Promptly take care of any flashing issues.

Sagging Roof Line

If you notice your roofline showing signs of sagging or unevenness, it could be a sign of 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.
