How To Choose a Roofing Company

Installing a new roof is a major home renovation that might cost tens of thousands of dollars when finished. It's crucial to research extensively to find the most qualified and trustworthy roofing company for the job. Here are some key factors to consider when hiring a roofer.

• Responsiveness and communication: From quote to project completion, your contractor should maintain ongoing communication with you, respond to all questions, and resolve any concerns.
• References and reviews: Vet companies thoroughly by looking on Google, Yelp, or the Better Business Bureau (BBB) to see that they have a history of consistently positive feedback. You can also request recent local references to learn more.
• Detailed written estimate: Quality roofers will provide detailed written proposals. These proposals should outline the full scope of the project, materials required, and total cost without hidden fees. Avoid vague quotes or ones that seem much too low or high.
• Experience and credentials: Companies operating for over a decade demonstrate years of experience on top of quality work and satisfied customers. Only consider companies that are licensed, bonded, and insured. Ask about professional certifications, such as those from the National Roofing Contractors Association.
• 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.
• Roofing materials and products: Quality roofing materials from top brands are able to handle Danville's weather and hold up for decades. Beware of contractors who offer extremely low-cost or generic products. Review shingle samples before making a decision.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof on a daily basis, it plays a vital protective role for your home. Be attentive for these common signs that your roof may need inspection and repairs from a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most popular residential roofing material, typically last 20–25 years before needing replacement. Have your roof evaluated if it’s approaching or past this lifespan to determine if full replacement is needed.

Leaks or Water Stains in Your Home

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

Exposed Roof Decking Underneath Shingles

If you can see roof deck boards or sheathing under shingles, it means 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 entering your home.

Cracked, Broken, or Missing Shingles

Carefully examine your shingles from the ground or a steady ladder. Look for any shingles that are cracked or have lost their protective granule coating. Over time, environmental factors like storms can cause surface damage. To keep your roof in good shape, we recommend replacing any shingles that are no longer attached properly or that have gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing makes a watertight seal around vents, valleys, chimneys, and other areas where water can penetrate your roof. Peeling, cracked, or deteriorated flashing can allow leaks. We recommend quickly addressing any flashing issues that come up.

Sagging Roof Line

A structural problem can cause your roof to sag or slope unevenly. If you notice signs of the roof sagging, schedule a professional inspection. An improperly supported roof deck will get worse over time.
