How To Choose a Roofing Company

Installing a new roof is a big home renovation that might cost over ten thousand dollars total when finished. It's crucial to research extensively to find the best credentialed and most respected roofing company for the job. Here are the main things to consider when picking a roofer.

• Experience and credentials: Seek out providers that have been operating for a decade or more. These companies' longevity and years in business reflects stability, expertise, and satisfied past clients. Ensure a provider has appropriate licenses, bonds, and insurance before committing. Also ask about professional certifications, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Quality roofing materials from leading manufacturers are able to handle Port Jefferson's weather and last for decades. Beware of contractors who push extremely low-cost or generic products. Review shingle samples before deciding.
• Warranties and guarantees: A reliable roofer will provide strong guarantees from the manufacturer which protect shingles for over 30 years along with at least a 5-year guarantee on workmanship. Be wary of shorter guarantees.
• References and reviews: Research companies carefully by reviewing their profiles on review sites such as Google, Yelp, or the Better Business Bureau (BBB) and looking for years of consistently positive feedback. Also ask for recent local references.
• Detailed written estimate: Dependable roofers will provide a thorough written quote. The estimate should specify the full scope of the project, materials to be used, and total cost with no surprise charges. Avoid providers that offer unclear bids, or ones that seem way too high or low.
• Responsiveness and communication: From estimate to project completion, your roofer should keep in consistent contact with you, answer all questions, and handle any concerns.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it plays a vital role protecting your home. 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 popular 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 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 lead to mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing visible under your shingles, it means those shingles are curling substantially or losing their seal, and replacement is required. Shingles should lie flat to keep water from leaking into your house.

Cracked, Broken, or Missing Shingles

Inspect your shingles thoroughly from ground level or a steady ladder. Look for ones that have cracks 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 are no longer attached properly or are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a watertight seal around vents, chimneys, valleys, and other areas where water can penetrate your roof. Peeling, cracked, or deteriorated flashing can allow leaks. We recommend promptly resolving any problems with the roof flashing that come up.

Sagging Roof Line

If your roof sags or is uneven, 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 worsen over time.
