How To Choose a Roofing Company

Installing a new roof is a big home improvement project that can cost an amount in the tens of thousands range in the end. It's essential to research and find a top quality and trusted local roofing contractor for the job. Here are some key considerations when choosing a roofing contractor.

• References and reviews: Research companies carefully by examining their Google, Yelp, or Better Business Bureau (BBB) profiles to look for years of consistently positive feedback. Also ask for recent local references.
• Responsiveness and communication: Your contractor should keep you regularly updated throughout, from the estimate to the completion of the project. A representative should respond to questions in a timely manner and address any worries while working.
• Detailed written estimate: Trustworthy roofing providers will give you a comprehensive written proposal. This quote should outline the complete work plan, materials needed, and total price with no surprise costs. Steer clear of unclear quotes, or ones that seem much too high or low.
• Warranties and guarantees: Reputable roofers provide strong manufacturer warranties covering shingles for 30+ years and workmanship warranties for five or more years. Use caution with roofers offering shorter warranties.
• Experience and credentials: Companies that have been in business for over 10 years 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.
• Roofing materials and products: Quality roofing materials from leading manufacturers can handle San Francisco's weather and last years. Avoid contractors offering cheap or generic materials. Review shingle samples before deciding.

Signs Your Roof Needs Repair or Replacement

Though it likely doesn't cross homeowners' minds daily, your roof plays a key role in protecting your home. Be attentive to these common signs that your roof may need an inspection and repairs from a professional roofer.

Roof Age

The age and material of your roof are key factors. Asphalt shingles, the most common residential roofing material, typically last about 20 to 25 years before needing to be replaced. 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 ceilings, walls, and insulation — or in your attic — usually mean 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 keep water from leaking into your house.

Cracked, Broken, or Missing Shingles

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

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a watertight seal around chimneys, vents, valleys, and other areas where water can penetrate your roof. Deteriorated, cracked, or peeling flashing can allow leaks. We recommend promptly resolving any problems with the roof flashing that come up.

Sagging Roof Line

A structural problem can cause your roof to exhibit noticeable sagging or unevenness in slope. If you notice unevenness, schedule a professional inspection. A roof deck that isn't reinforced will continue to deteriorate over time.
