How To Choose a Roofing Company

Installing a new roof is a big home renovation that can cost over ten thousand dollars total. It's essential to research thoroughly to find a highly skilled and reputable roofing company for the job. Here are some important considerations when picking a roofer.

• Detailed written estimate: Reputable roofers will give you a comprehensive written estimate that outlines the full scope of the work, specific materials, and total cost without hidden fees. Avoid vague quotes or ones that seem dramatically high or low.
• Roofing materials and products: Quality roofing materials from top brands are able to withstand Livermore's weather and hold up for decades. Beware of contractors who push extremely low-cost materials or generic products. Check out shingle samples before making a decision.
• Experience and credentials: Companies that have been in business for over 10 years show stability and expertise. Before hiring, verify that a provider has proper licenses, bonding, and insurance. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• Warranties and guarantees: Reputable roofing companies provide strong guarantees that cover your roof. Look for coverage on shingles lasting 30+ years and at least a 5-year labor guarantee. Stay away from companies that have less coverage than that.
• References and reviews: Check companies thoroughly by checking their latest online reviews on Google, Yelp, or the Better Business Bureau (BBB) and looking for a history of consistently good feedback over many years. You can ask for recent local references to learn more.
• Responsiveness and communication: From estimate to project completion, your roofer should regularly communicate with you, respond to all questions, and handle any concerns.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it plays a vital role protecting your home. Look out for 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 key factors. Asphalt shingles, the most common residential roofing material, typically last about 20 to 25 years before needing replacement. 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 walls, insulation, and ceilings — or in your attic — usually mean that water is seeping through deteriorating 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 visible under your shingles, it means those shingles are curling substantially or losing their seal and need to be replaced. Shingles should lie flat to keep water from entering your house.

Cracked, Broken, or Missing Shingles

Examine your shingles closely from a steady ladder or while on the ground. Look for shingles that show cracks or are missing granules. Storms can cause exterior damage over time. To keep your roof in good shape, replace any shingles that are no longer attached or are openly gaping.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof creates a watertight barrier around chimneys, valleys, vents, and other areas where water can leak in. If the flashing is developing cracks, peeling away, or deteriorating over time, it may leak. Promptly address any flashing issues.

Sagging Roof Line

If you notice your roofline showing signs of sagging or unevenness, it could be a sign of a problem with the structure that requires further inspection by a roofer. A sagging roof deck will worsen over time if not given proper reinforcement or replaced entirely.
