How To Choose a Roofing Company

Roof installation is a major home improvement project that can cost upwards of twenty thousand dollars out of pocket. 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: Seek out providers that have been operating for a decade or more. These companies' longevity and years in business reflects consistent work, knowledgeable teams, and happy former customers. Confirm that a provider has appropriate licenses, bonds, and insurance before hiring. Also inquire about professional certifications, such as those from the National Roofing Contractors Association.
• 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 track record of consistently good feedback. Requesting local references is another great way to learn more about the customer experience.
• Roofing materials and products: Leading manufacturers produce durable roofing materials that can withstand Manassas' weather for years. Avoid contractors offering low-cost or generic products. Review shingle samples before making a decision.
• Warranties and guarantees: Reputable roofers provide robust guarantees from shingle manufacturers which protect shingles for over 30 years and labor guarantees for at least 5 years. Use caution with roofers offering less coverage than that.
• Detailed written estimate: Quality roofers will provide a thorough written proposal. The estimate should specify the full project scope, materials to be used, and full price with no surprise charges. Avoid providers that offer unclear quotes, or ones that seem way too low or high.
• Responsiveness and communication: Your contractor should communicate consistently throughout, from the estimate to project completion. A representative should answer questions quickly and address any concerns while working.

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 both important. The most common residential roofing material is asphalt shingles, which generally last around 20–25 years before needing to be replaced. Schedule an inspection if your roof is approaching this age to determine if a full replacement is needed.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof problem is leaking. Stains on ceilings, insulation, and walls — or in your attic — usually mean that water is seeping through worn or damaged shingles. Don't ignore small leaks, because even these can encourage mold growth and roof deterioration.

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 need to lie flat to stop water from leaking into your home.

Cracked, Broken, or Missing Shingles

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

Flashing Deterioration Around Roof Penetrations

Roof flashing provides a watertight seal around chimneys, vents, valleys, and other areas where water can leak into your home. Deteriorated, cracked, or peeling flashing can allow leaks. We recommend promptly resolving any flashing issues that come up.

Sagging Roof Line

An uneven roofline may be a sign of a structural issue that requires professional evaluation. Without properly addressing and resolving the issue, a sagging roof will worsen over time.
