How To Choose a Roofing Company

Installing a new roof is a big home renovation that can cost tens of thousands of dollars when finished. It's essential to research thoroughly to find the best credentialed and most respected roofing company for the job. Here are some important considerations when picking a roofer.

• 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. Avoid companies with shorter warranty periods.
• Detailed written estimate: Legitimate roofing companies will provide a thorough written proposal. The estimate should detail the full project scope, materials needed, and full price with no surprise charges. Avoid companies that provide unclear bids, or ones that seem way too low or high.
• Roofing materials and products: Quality roofing materials from leading manufacturers are able to handle Annandale's weather and hold up for decades. Beware of contractors who offer extremely low-cost or generic products. Check out shingle samples before making a decision.
• Experience and credentials: Companies operating for over a decade have a proven history and track record of expert service and happy clients. Make sure any provider you consider is licensed, bonded, and insured. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• Responsiveness and communication: Your contractor should communicate consistently throughout, from the quote to the completion of the project. A representative should answer questions in a timely manner and resolve any concerns while working.
• References and reviews: Vet companies by examining their latest customer reviews on Google, Yelp, or the Better Business Bureau (BBB) to look for a track record of consistently positive reviews. You can also request recent local references to learn more about the customer experience.

Signs Your Roof Needs Repair or Replacement

While most homeowners don't think about their roof every day, it plays a key role in protecting your home. Watch for these common signs that your roof may need an inspection and repairs from a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, normally last about 20 to 25 years before needing to be replaced. Have your roof evaluated if it’s approaching 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 a roof issue is leaking. Stains on walls, insulation, and ceilings — or in your attic — usually indicate that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can encourage mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

Visible roof decking or sheathing under your shingles indicates that those shingles are severely curling or losing their seal. This means it's time for replacement. Shingles need to lie flat to stop water from leaking into your home.

Cracked, Broken, or Missing Shingles

Carefully examine your shingles from the ground or a safe ladder. Look for any shingles that have cracked or are missing granules. Over time, environmental factors like storms can cause surface damage. To keep your roof in good repair, you should replace any shingles that are no longer attached properly or that have gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing protects vents, chimneys, valleys, and other areas that penetrate your roofing system. If the metal flashing is damaged, coming loose, or deteriorated, it can leak. Have any issues with roof flashing fixed right away.

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.
