How To Choose a Roofing Company

Installing a new roof is a major home improvement project that can cost an amount in the tens of thousands range in the end. It's crucial to research and find a top quality and trusted local roofing contractor for the job. Here are the key factors to consider when choosing a roofing contractor.

• Roofing materials and products: Quality roofing materials from top brands are able to handle Mercer Island's weather and hold up for decades. Beware of contractors who offer extremely low-cost or generic products. Check out shingle samples before deciding.
• Warranties and guarantees: The best roofers provide robust manufacturer warranties on shingles lasting over 30 years, together with at least a 5-year labor guarantee. Stay away from companies with shorter warranty periods.
• Experience and credentials: Companies operating for over a decade demonstrate years of experience on top of expert service and happy clients. Make sure any provider you consider is licensed, bonded, and insured. Ask about professional certifications, such as those from the National Roofing Contractors Association.
• Responsiveness and communication: From quote to project completion, your contractor should maintain ongoing communication with you, answer all questions, and handle any concerns.
• 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.
• Detailed written estimate: Trustworthy roofing companies will provide detailed written bids. These bids should outline the full scope of the project, materials needed, and total cost without hidden fees. Avoid vague bids or ones that seem much too low or high.

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, generally last 20–25 years before needing to be replaced. Have your roof evaluated if it’s 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 roof trouble is water leaks. Stains on your insulation, ceilings, or walls, or in your attic likely indicate water seeping through worn or damaged shingles. Even small leaks should be fixed promptly, as they can cause mold growth and further damage your roof.

Exposed Roof Decking Underneath Shingles

If you can see roof sheathing or decking under shingles, it means that those shingles are severely curling or losing their seal. This means the shingles likely need replacement. Shingles need to lie flat to prevent water from getting into your home.

Cracked, Broken, or Missing Shingles

Examine your roof shingles from the ground or a steady ladder. Look for tears in the shingle surface or missing granules. Storms that bring strong winds can cause surface damage over time. To maintain your roof, replace any shingles that have come loose or have open gaps.

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 address any flashing issues.

Sagging Roof Line

If your roof shows signs of sagging or unevenness, it's time to call a professional roofer. These issues could indicate a structural problem. A sagging roof that's not reinforced or replaced will deteriorate more over time.
