How To Choose a Roofing Company

A new roof installation is a large home renovation that can cost over twenty thousand dollars total. It's crucial to research and find a top-rated, trusted roofing company for the job. Here are some important considerations for selecting a roofer.

• Detailed written estimate: Legitimate roofing companies will provide a thorough written estimate. The proposal should specify the full scope of the project, materials required, and full price with no surprise charges. Avoid providers that offer unclear quotes, or ones that seem way too high or low.
• Roofing materials and products: Quality roofing materials from top brands can withstand Lake Oswego's weather and last years. Watch out for contractors offering cheap or generic materials. Inspect shingle samples before deciding.
• Experience and credentials: Companies operating for over a decade have a proven history and track record of quality work and satisfied customers. Only consider companies that are licensed, bonded, and insured. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• References and reviews: Check companies thoroughly by reviewing their most recent online feedback on Google, Yelp, or the Better Business Bureau (BBB) to look for consistently good feedback over many years. Also request recent local references to find out more.
• 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. Be cautious of companies with shorter warranty periods.
• Responsiveness and communication: From the time you get a quote to project completion, a roofing contractor should communicate consistently. A representative should address questions and deal with any issues during the project.

Signs Your Roof Needs Repair or Replacement

Though most homeowners don't think about their roof every single day, a roof plays a vital role in keeping a home safe and secure. Keep alert for these signs that your roof might need professional attention.

Roof Age

Your roof's age and material are key factors. The most popular residential roofing material is asphalt shingles, which generally last 20–25 years before requiring replacement. Have your roof evaluated if it’s reaching 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 issue is leaking. Stains on ceilings, insulation, and walls — 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

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

Cracked, Broken, or Missing Shingles

Carefully inspect your shingles from the ground or a safely-placed ladder. Look for any shingles that have cracks or have lost their protective granule coating. Over time, environmental factors like storms can cause surface damage. To keep your roof in good repair, you should replace any dislodged or gaping shingles.

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 properly addressing and resolving the issue, a sagging roof will get worse over time.
