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 essential to research and find a top-rated, trusted roofing company for the job. Here are the top things to evaluate when choosing a roofer.

• Responsiveness and communication: From estimate to project completion, your contractor should maintain ongoing communication with you, respond to all questions, and resolve any concerns.
• Detailed written estimate: Trustworthy roofers will offer a comprehensive estimate in writing that outlines the scope of the work, specific materials, and total cost without hidden fees. Avoid vague bids or quotes that seem dramatically high or low.
• Warranties and guarantees: A reliable roofer will provide robust manufacturer warranties that cover shingles for 30+ years along with at least a 5-year guarantee on workmanship. Be wary of shorter guarantees.
• Roofing materials and products: Quality roofing materials from top brands can withstand Foster City's weather and endure years. Avoid contractors offering cheap or generic materials. Inspect shingle samples before deciding.
• Experience and credentials: Providers with a decade or more of experience show stability and expertise. Before hiring, make sure the company has appropriate licenses, bonding, and insurance. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• 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.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof daily, but it protects your home in important ways. Look out for these common signals that your roof needs to be evaluated and repaired by a professional roofer.

Roof Age

The age and material of your roof play a big role. Asphalt shingles, the most common roofing material for homes, typically last about around 20–25 years. If your roof is approaching or past this lifespan, get it inspected to see if complete replacement is necessary.

Leaks or Water Stains in Your Home

One of the most obvious signs of roof trouble is water leaks. Stains on your insulation, ceilings, or walls, or in your attic are often a sign of water seeping through worn or damaged shingles. Even small leaks should not be ignored, as they can cause mold growth and further damage your roof.

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

Cracked, Broken, or Missing Shingles

Check your roof shingles from the ground or a safe ladder. Look for cracking 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 protects vents, valleys, chimneys, and other areas that pass through the roof. 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 fixing or replacing it, a sagging roof will continue deteriorating.
