How To Choose a Roofing Company

Installing a new roof is a large home improvement project that can cost tens of thousands of dollars. It’s crucial to do your research and find the best company for the job. Here are the key factors to consider when choosing a roofer.

• Experience and credentials: Seek out providers that have been operating for a decade or more. These companies' extensive experience and time in operation reflects stability, expertise, and satisfied past clients. Ensure a provider has appropriate licenses, bonds, and insurance before hiring. Also ask about professional certifications, such as those from the National Roofing Contractors Association.
• Responsiveness and communication: From estimate to project completion, your contractor should maintain ongoing communication with you, respond to all questions, and address any concerns.
• Detailed written estimate: Reputable roofing companies will provide detailed written bids. These proposals should outline the full scope of the project, materials needed, and total cost with no hidden fees. Avoid vague bids or quotes that seem much too low or high.
• Roofing materials and products: Quality roofing materials from leading manufacturers are able to handle Columbia's weather and hold up for decades. Beware of contractors who push extremely low-cost or generic products. Check out shingle samples before deciding.
• References and reviews: Check companies thoroughly by verifying recent reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for a history of consistently good feedback over many years. Also request recent local references to find out more.
• Warranties and guarantees: The best roofers provide robust manufacturer warranties on shingles lasting over 30 years, together with at least a 5-year labor warranty. Watch out for companies with shorter warranty periods.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every day, it plays a vital protective role for your home. Keep watch for these common signs that your roof may need professional inspection and repair.

Roof Age

Your roof's age and material are key factors. The most common residential roofing material is asphalt shingles, which normally last around 20–25 years before needing to be replaced. Schedule an inspection if your roof is reaching this age to determine 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 walls, ceilings, and insulation — or in your attic — usually indicate that water is seeping through deteriorating shingles. Don't ignore small leaks, because even these can encourage mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

Visible roof decking or sheathing under your shingles indicates that those shingles are severely curling or losing their seal. This means the shingles likely need replacement. Shingles should lie flat to stop water from getting into your home.

Cracked, Broken, or Missing Shingles

Check your shingles thoroughly from ground level or a steady ladder. Look for ones that have cracks or that are missing granules. Over time, windy conditions can cause surface damage. To keep your roof in repair, replace any shingles that are no longer attached properly or are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing seals off vents, valleys, chimneys, and other areas that penetrate your roofing system. 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 your roof sags or is uneven, it's time to call a professional roofer. These issues could signal a structural problem. A sagging roof that's not properly supported or fixed will deteriorate more over time.
