How To Choose a Roofing Company

A new roof installation is a major home renovation that can cost tens of thousands of dollars. It's essential to research and find the most qualified and reputable roofing company for the job. Here are some important considerations for choosing a roofer.

• Experience and credentials: An established roofing provider 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 hiring. Inquire about any professional certifications that relate to your project, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Quality roofing materials from leading manufacturers are able to handle Islip's weather and hold up for decades. Beware of contractors who offer extremely low-cost materials or generic products. Review shingle samples before deciding.
• References and reviews: Vet companies thoroughly by checking online review sites like Google, Yelp, or the Better Business Bureau (BBB) for years of consistently positive feedback. Request recent local references from the company to learn more.
• Responsiveness and communication: From estimate to project completion, your roofer should maintain ongoing communication with you, answer all questions, and resolve any concerns.
• Detailed written estimate: Legitimate roofers will provide a thorough written proposal. The quote should detail the full project scope, materials needed, and total cost with no surprise charges. Avoid providers that offer unclear bids, or ones that seem way too low or high.
• 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.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it protects your home in important ways. Look out for these common signals that your roof needs to be checked and repaired by a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, normally last around 20–25 years before needing to be replaced. Schedule a professional inspection if your roof is nearing or past this lifespan to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

One of the most obvious signs of roof trouble is water leaks. Stains on your insulation, walls, or ceilings, or in your attic are often a sign of water seeping through damaged or worn shingles. Even small leaks should not be ignored, as they can cause mold growth and further damage to your roof.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing underneath your shingles, it means those shingles are curling substantially or losing their seal and need to be replaced. Shingles should lie flat to keep water from getting into your home.

Cracked, Broken, or Missing Shingles

Check your shingles thoroughly from ground level or a sturdy ladder. Look for ones that are cracked or that no longer have their protective coating. Over time, storms can cause surface damage. To keep your roof in good condition, replace any shingles that detach or have gaping holes.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a barrier against the elements around valleys, vents, chimneys, and other areas that penetrate your roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Problems with roof flashing should be addressed promptly.

Sagging Roof Line

An uneven roofline may indicate a structural issue that requires professional evaluation. Without taking steps to fix or replace it, a sagging roof will worsen over time.
