How To Choose a Roofing Company

Roof installation is a major home improvement project that can cost a significant amount. It’s essential to do your research and find the most qualified company for the job. Here are the key factors to consider when choosing a roofer.

• Responsiveness and communication: From the time you get a quote to when the project is complete, your roofer should keep you regularly updated. A representative should respond to questions and deal with any issues during the project.
• 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 properly licensed, bonded, and insured. Ask about professional certifications, such as those from the National Roofing Contractors Association.
• Detailed written estimate: Quality roofers will provide a thorough written proposal. The estimate should specify the full scope of the project, materials required, and total cost with no surprise charges. Avoid companies that provide unclear quotes, or ones that seem way too low or high.
• References and reviews: Research companies carefully by checking reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for years of consistently good feedback. Also ask for recent local references.
• Roofing materials and products: Quality roofing companies sell quality materials that can handle Janesville's weather and last a long time. Be careful of contractors pushing extremely inexpensive or generic options. Inspect shingle samples before committing.
• Warranties and guarantees: Reputable roofers provide robust guarantees from shingle manufacturers which protect shingles for over 30 years and workmanship warranties for five or more years. Use caution with roofers offering shorter warranties.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof on a daily basis, it provides critical protections for your home. Remain alert for these common signs that your roof may need professional inspection and repair.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most common residential roofing material, typically last around 20–25 years before needing replacement. If your roof is approaching or past this lifespan, get a professional inspection to determine if full replacement is needed.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof problem is leaking. Stains on insulation, ceilings, and walls — 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 deterioration.

Exposed Roof Decking Underneath Shingles

If you can see your roof deck boards underneath your shingles, it means those shingles are severely curling or losing their seal and need to be replaced. Shingles should lie flat to keep water from getting into your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a safe ladder. Look for signs of damage or missing granules. Storms that bring strong winds can cause surface damage over time. To keep your roof in good shape, replace any shingles that have come loose or are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing seals off valleys, vents, chimneys, and other areas that pass through the roof. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any issues with roof flashing fixed right away.

Sagging Roof Line

If you notice your roofline showing signs of sagging or unevenness, it could signal a problem with the structure that requires further inspection by a roofer. A sagging roof deck will worsen over time if not given proper reinforcement or replaced entirely.
