How To Choose a Roofing Company

Installing a new roof is a big home renovation that may cost tens of thousands of dollars when finished. It's crucial to research in depth to find the best credentialed and most respected roofing company for the job. Here are some key factors to consider when picking a roofer.

• Roofing materials and products: Reputable roofing companies sell quality materials that can handle Commerce's weather and endure a long time. Be careful of contractors offering extremely low-cost or generic options. Check out shingle samples before committing.
• Responsiveness and communication: From estimate to project completion, your contractor should regularly communicate with you, answer all questions, and address any concerns.
• 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 shorter warranty periods.
• Detailed written estimate: Quality roofers will provide a thorough written quote. The proposal should detail the full scope of the project, materials needed, and total cost with no surprise charges. Avoid companies that provide unclear bids, or ones that seem way too high or low.
• Experience and credentials: An established roofing company that has been operating for over a decade demonstrates years of expertise, satisfied customers, and consistent quality work. Ensure the company is fully licensed, bonded, and insured before hiring. Inquire about any professional certifications relating your project, such as those from the National Roofing Contractors Association.
• References and reviews: Vet companies by examining their latest customer reviews on Google, Yelp, or the Better Business Bureau (BBB) to 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

While the average homeowner may not spend a lot of time thinking about their roof, a roof plays an important role in keeping a home safe and secure. Watch for these signs that your roof might need professional attention.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, typically last 20–25 years before needing replacement. Schedule a professional inspection if your roof is nearing or past this lifespan to determine if full replacement is needed.

Leaks or Water Stains in Your Home

One of the most obvious signs of a roof issue is leaking. Stains on insulation, ceilings, and walls — 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 deterioration.

Exposed Roof Decking Underneath Shingles

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

Cracked, Broken, or Missing Shingles

Examine your shingles thoroughly from ground level or a sturdy ladder. Look for ones that have cracks or that are missing granules. Over time, storms can cause surface damage. To keep your roof in good condition, replace any missing shingles or ones that have gaping holes.

Flashing Deterioration Around Roof Penetrations

Roof flashing makes a watertight seal around valleys, vents, chimneys, and other areas where water can penetrate your roof. Deteriorated, cracked, or peeling flashing can allow leaks. We recommend promptly resolving any flashing issues that come up.

Sagging Roof Line

An uneven roofline may indicate a structural issue that requires professional evaluation. Without properly addressing and resolving the issue, a sagging roof will get worse over time.
