How To Choose a Roofing Company

Installing a new roof is a big home renovation that might cost tens of thousands of dollars when finished. It's essential to research thoroughly to find the best credentialed and most respected roofing company for the job. Here are some important considerations when picking a roofer.

• References and reviews: Vet companies by examining their latest customer reviews on Google, Yelp, or the Better Business Bureau (BBB) to look for a track record of consistently good feedback. You can also request recent local references to learn more about the customer experience.
• 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 you hire them. Inquire about any professional certifications relating your project, such as those from the National Roofing Contractors Association.
• Detailed written estimate: Trustworthy roofing companies will offer a comprehensive estimate in writing that outlines the full scope of the work, materials requirements, and total cost with no hidden fees. Avoid vague quotes or ones that seem dramatically low or high.
• Roofing materials and products: Reputable manufacturers produce durable roofing materials that can endure Mankato's weather for years. Avoid contractors offering low-cost or generic products. Inspect shingle samples before making a decision.
• Responsiveness and communication: From the time you get a quote to when the project is complete, a roofing contractor should communicate consistently. A representative should respond to questions and resolve any issues during the project.
• Warranties and guarantees: A reliable roofer will provide strong guarantees from the manufacturer which protect shingles for over 30 years along with at least a 5-year guarantee on workmanship. Be wary of shorter warranty periods.

Signs Your Roof Needs Repair or Replacement

Though it likely doesn't cross homeowners' minds daily, your roof plays a key role in protecting your home. Look out for these common signs that your roof may need an inspection and repairs from a professional roofer.

Roof Age

Your roof's age and material are key factors. The most popular residential roofing material is asphalt shingles, which typically last about 20 to 25 years before requiring replacement. Have your roof evaluated if it’s approaching this age to determine if a 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 ceilings, insulation, and walls — or in your attic — usually indicate that water is seeping through damaged or worn 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 visible under 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 leaking into your house.

Cracked, Broken, or Missing Shingles

Inspect your shingles closely from a steady ladder or while on the ground. Look for shingles that have cracked or no longer have their protective granule layer. Storms can cause roof damage over time. To keep your roof in good condition, replace any shingles that are no longer attached or have gaping holes.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a barrier against the elements around vents, valleys, chimneys, and other areas that penetrate the roof. If this metal flashing is coming loose, cracked open, or worn down, it can allow leaks. Any issues with flashing should be addressed promptly.

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 properly supported or replaced.
