How To Choose a Roofing Company

Installing a new roof is a major home improvement project that can cost upwards of twenty thousand dollars out of pocket. It’s essential to do your research and find the best 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, a roofing contractor should keep you regularly updated. A representative should address questions and handle any issues during the project.
• 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: Research companies carefully by reviewing their profiles on review sites such as Google, Yelp, or the Better Business Bureau (BBB) and looking for years of consistently positive feedback. You can also request recent local references.
• Detailed written estimate: Quality roofing companies will provide a thorough written proposal. The proposal should detail the full project scope, materials required, and full price with no surprise charges. Avoid companies that provide unclear quotes, or ones that seem way too low or high.
• Warranties and guarantees: Reputable roofers provide strong manufacturer warranties covering shingles for 30+ years and labor guarantees for at least 5 years. Use caution with roofers offering less coverage than that.
• Roofing materials and products: Reputable roofing companies sell quality materials that can withstand Los Altos Hills' weather and endure a long time. Be careful of contractors offering extremely low-cost or generic options. Inspect shingle samples before committing.

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. 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 both important. The most common residential roofing material is asphalt shingles, which generally last around 20–25 years before needing to be replaced. Have your roof evaluated if it’s 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 insulation, walls, and ceilings — or in your attic — usually indicate that water is seeping through worn or damaged shingles. Don't ignore small leaks, because even these can lead to mold growth and roof deterioration.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing beneath your shingles, it means those shingles are severely curling or losing their seal and need to be replaced. Shingles should lie flat to prevent water from entering your house.

Cracked, Broken, or Missing Shingles

Check your shingles thoroughly from ground level or a safe ladder. Look for ones that are damaged or that no longer have their protective coating. Over time, storms can cause surface damage. To keep your roof in good condition, replace any shingles that are no longer attached properly or have gaping holes.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof creates a watertight barrier around chimneys, vents, valleys, and other areas where water can penetrate the roofing system. If the flashing is becoming damaged, loose, or worn down, it may leak. Promptly address any flashing issues.

Sagging Roof Line

An uneven roofline may mean there's a structural issue that requires professional evaluation. Without properly addressing and resolving the issue, a sagging roof will continue deteriorating.
