How To Choose a Roofing Company

Installing a new roof is a large home improvement project that can cost tens of thousands of dollars. It’s essential to do your research and find the top-rated company for the job. Here are the key factors to consider when selecting a roofer.

• Detailed written estimate: Trustworthy roofing companies will give you a comprehensive estimate in writing that outlines the scope of the work, specific materials, and total cost with no hidden fees. Avoid vague bids or quotes that seem dramatically high or low.
• References and reviews: Vet companies thoroughly by verifying on review sites such as Google, Yelp, or the Better Business Bureau (BBB) that they have consistently positive feedback. You can also request recent local references to learn more.
• Roofing materials and products: Reputable roofing companies sell quality materials that can handle O'Fallon's weather and endure a long time. Be careful of contractors pushing extremely inexpensive or generic options. Inspect shingle samples before committing.
• Responsiveness and communication: Your contractor should communicate consistently throughout, from the estimate to project completion. A representative should answer questions quickly and handle any issues while working.
• Warranties and guarantees: A reliable roofer will provide robust manufacturer warranties that cover shingles for 30+ years along with at least a 5-year workmanship warranty on labor. Be wary of shorter warranty periods.
• Experience and credentials: An established roofing company that has many years of experience in business demonstrates stability, experience, and a proven track record. Ensure the company is fully licensed, bonded, and insured before you hire them. Inquire about any professional certifications relating your project, such as those from the National Roofing Contractors Association.

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. Remain alert for these common signs that your roof may need inspection and repairs from a professional roofer.

Roof Age

The age and material of your roof play a big role. Asphalt shingles, the most popular roofing material for homes, typically last about 20 to 25 years. If your roof is approaching or past this lifespan, schedule an inspection to see 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 ceilings, walls, and insulation — or in your attic — usually mean that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can encourage mold growth and roof deterioration.

Exposed Roof Decking Underneath Shingles

Seeing roof deck boards or sheathing under your shingles indicates that those shingles are severely curling or losing their seal. This means the shingles likely need 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 safe ladder or while on the ground. Look for shingles that are cracked or no longer have their protective granule layer. Storms can cause roof damage over time. To keep your roof in good condition, replace any missing shingles, or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a watertight seal around chimneys, valleys, vents, and other areas where water can leak into your home. Peeling, cracked, or deteriorated 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 attention. Without fixing or replacing it, a sagging roof will worsen over time.
