How To Choose a Roofing Company

Roof installation is a large home improvement project that can cost tens of thousands of dollars. It’s crucial to do your research and find the most qualified company for the job. Here are the key factors to consider when selecting a roofer.

• Experience and credentials: Companies that have been in business for over 10 years show consistent quality and customer satisfaction. Before hiring, verify that a provider has proper licenses, bonding, and insurance. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• 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. Be cautious of companies with shorter warranty periods.
• Detailed written estimate: Reputable roofing companies will give you a comprehensive estimate in writing that outlines the scope of the work, materials requirements, and total cost without hidden fees. Avoid vague bids or quotes that seem dramatically low or high.
• References and reviews: Check companies thoroughly by verifying recent reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for consistently good feedback over many years. You can ask for recent local references to learn more.
• Responsiveness and communication: From estimate to project completion, your contractor should maintain ongoing communication with you, answer all questions, and resolve any concerns.
• Roofing materials and products: Quality roofing materials from leading manufacturers can withstand Hollis' weather and last years. Be wary of contractors pushing cheap or generic materials. Inspect shingle samples before deciding.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every single day, a roof plays a vital role in keeping a home safe and secure. Keep alert 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 to be replaced. Schedule a professional inspection if your roof is approaching or past this lifespan to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

Leaks are a clear sign that your roof requires repairs. Stains on ceilings, walls, or insulation, or in your attic often signal that water is getting through damaged or worn shingles. Even minor leaks should be taken care of right away, as they can result in mold and more harm over time.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing beneath 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 entering your house.

Cracked, Broken, or Missing Shingles

Inspect your shingles closely from a steady ladder or while on the ground. Look for shingles that are cracked or are missing granules. Storms can cause roof damage over time. To keep your roof in good shape, replace any missing shingles, or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a weatherproof seal around valleys, chimneys, vents, 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

If your roof sags or is uneven, schedule a professional inspection. These issues could indicate a structural problem. A sagging roof that's not properly supported or fixed will deteriorate more over time.
