How To Choose a Roofing Company

A new roof installation is a major home renovation that can cost tens of thousands of dollars. It's essential to research and find the most qualified and reputable roofing company for the job. Here are some important considerations for selecting a roofer.

• Warranties and guarantees: The best roofers provide robust manufacturer warranties on shingles lasting over 30 years, together with at least a 5-year labor warranty. Avoid companies with shorter warranty periods.
• Experience and credentials: Seek out providers that have been operating for a decade or more. These companies' longevity and years in business reflects consistent work, knowledgeable teams, and happy former customers. Confirm that a provider has appropriate licenses, bonds, and insurance before hiring. Also inquire about professional certifications, such as those from the National Roofing Contractors Association.
• Roofing materials and products: Quality roofing materials from top brands are able to handle San Anselmo's weather and last for decades. Beware of contractors who push extremely low-cost materials or generic products. Check out shingle samples before making a decision.
• Detailed written estimate: Trustworthy roofers will provide detailed written proposals. These bids should outline the full project scope, materials needed, and total cost without hidden fees. Avoid vague bids or ones that seem much too low or high.
• Responsiveness and communication: Your contractor should maintain regular contact throughout, from the quote to the completion of the project. A representative should respond to questions in a timely manner and handle any issues while working.
• 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. Request recent local references from the company 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. Be aware of these common signals that your roof needs to be inspected and repaired by a professional roofer.

Roof Age

The age and material of your roof are important. Asphalt shingles, the most common roofing material for homes, usually last about 20–25 years. If your roof is nearing or past this lifespan, get it inspected to see if it needs to be replaced.

Leaks or Water Stains in Your Home

Leaks are a frequent sign of roof issues. Water leaking through damaged or worn shingles often leads to water stains on walls, insulation, and ceilings, or in your attic. Don't neglect even small leaks, as leaks of any size can lead to mold and other damage.

Exposed Roof Decking Underneath Shingles

If you can see roof decking or sheathing visible under your shingles, it means those shingles are severely curling or losing their seal, and replacement is required. Shingles should lie flat to prevent water from getting into your home.

Cracked, Broken, or Missing Shingles

Inspect your roof shingles from the ground or a steady ladder. Look for tears in the shingle surface or missing granules. Storms that bring strong winds can cause surface damage over time. To maintain your roof, replace any shingles that have come loose or are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing seals off chimneys, vents, valleys, 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

If you notice your roofline sagging or sloping unevenly, it could indicate a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not reinforced or replaced.
