How To Choose a Roofing Company

Installing a new roof is a large home improvement project that can cost an amount in the tens of thousands range when all is said and done. It's essential to research and find the most qualified and reputable residential roofing company for the job. Here are some key considerations when choosing a roofing contractor.

• Experience and credentials: Companies operating for over a decade demonstrate years of experience on top of expert service and happy clients. Only consider companies that are properly licensed, bonded, and insured. Ask about professional certifications, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Quality roofing companies sell quality materials that can handle Renton's weather and last a long time. Be careful of contractors offering extremely low-cost or generic options. Inspect shingle samples before committing.
• References and reviews: Vet companies by reviewing their most recent online feedback on sites such as Google, Yelp, or the Better Business Bureau (BBB). Look for a history of consistently positive reviews. You can also request recent local references to learn more about the customer experience.
• Responsiveness and communication: From quote to project completion, your roofer should maintain ongoing communication with you, respond to all questions, and handle any concerns.
• 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. Avoid companies with shorter warranty periods.
• Detailed written estimate: Legitimate roofers will provide a thorough written estimate. The estimate should detail the full project scope, materials needed, and total cost with no surprise charges. Avoid companies that provide unclear quotes, or ones that seem way too high or low.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every day, it provides critical protections for your home. Remain alert for these common signs that your roof may need inspection and repairs from a professional roofer.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most common residential roofing material, typically last around 20–25 years before needing replacement. If your roof is nearing or past this lifespan, get a professional inspection to determine if full replacement is needed.

Leaks or Water Stains in Your Home

Leaks are a common sign of roof issues. Water leaking through damaged or worn shingles often leads to water stains on ceilings, walls, and insulation, or in your attic. Don't ignore even small leaks, as they can still cause mold and other issues.

Exposed Roof Decking Underneath Shingles

If you can see roof deck boards or sheathing under shingles, it means 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

Inspect your roof shingles from the ground or a steady ladder. Look for cracking or loss of protective granule coating. Storms that bring strong winds can cause surface damage over time. To keep your roof in good shape, replace any shingles that have come loose or have open gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a weatherproof seal around valleys, vents, chimneys, and other areas that penetrate the roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Any issues with flashing should be addressed promptly.

Sagging Roof Line

An uneven roofline may be a sign of a structural issue that requires professional attention. Without fixing or replacing it, a sagging roof will continue deteriorating.
