How Much Does a New Roof Cost in Glendora?

Budgeting is important when tackling a project as big as replacing your roof. Below, we provide the average price range for replacing a roof on a 1,500 square foot home in Glendora. We also outline price differences between common roof materials.

How To Choose a Roofing Company

A new roof installation is a large home renovation that can cost tens of thousands of dollars. It's crucial to research and find a highly reviewed and recommended roofing company for the job. Here are the top things to evaluate when choosing a roofer.

  • Experience and credentials: Companies that have been in business for over 10 years show consistent quality and customer satisfaction. Before hiring, make sure the company has current licenses, bonding, and insurance. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
  • Responsiveness and communication: From the time you get a quote to when the project is complete, your roofer should maintain regular contact. A representative should address questions and deal with any issues during the project.
  • Detailed written estimate: Reputable roofers will provide detailed written estimates. These proposals should outline the full scope of the project, materials needed, and total cost with no hidden fees. Avoid vague bids or quotes that seem much 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 shorter warranties.
  • Roofing materials and products: Quality roofing materials from top brands are able to handle Glendora's weather and last for decades. Beware of contractors who offer extremely low-cost or generic products. Inspect shingle samples before deciding.
  • 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. Request recent local references from the company to learn more.

Signs Your Roof Needs Repair or Replacement

While the average homeowner may not spend a lot of time thinking about their roof, a roof plays a vital role in keeping a home safe and secure. Be on the lookout for these signs that your roof might need professional attention.

Roof Age

The age and material of your roof are key factors. Asphalt shingles, the most popular residential roofing material, typically last around 20–25 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

Leaks are a typical sign of roof issues. Water leaking through worn or damage shingles often leads to water stains on insulation, ceilings, and walls, or in your attic. Don't dismiss even small leaks, as they can still cause mold and other issues.

Exposed Roof Decking Underneath Shingles

If you can see roof sheathing or decking under shingles, it means that those shingles are severely curling or losing their seal. This means it's time for replacement. Shingles need to lie flat to prevent water from getting into your home.

Cracked, Broken, or Missing Shingles

Inspect your shingles thoroughly from ground level or a safe ladder. Look for ones that have cracks or that are missing granules. Over time, storms can cause surface damage. To keep your roof in good shape, replace any missing shingles or ones that have gaping holes.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof creates a watertight barrier around vents, valleys, chimneys, 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

An uneven roofline may indicate a structural issue that requires professional attention. Without properly addressing and resolving the issue, a sagging roof will continue deteriorating.

Frequently Asked Questions About Roofing in Glendora, CA

The best type of roofing material for your home in Glendora will be decided by several factors, such as your budget and how often you want to do maintenance.

Asphalt is more budget-friendly, while materials like metal are more expensive but last longer. Clay roofing may be beneficial around Glendora due to its high solar reflectivity. Roofs of this type can help you save on cooling costs during the sunny summer months. You might be swayed by how environmentally friendly a material is, and opt for something like wood. If you live in a part of Glendora where the risk of wildfire damage is higher, choices like clay, metal, or treated wood might appeal to you.

In California, licensing is handled by the Department of Consumer Affairs Contractors State License Board. Contractors are required to have an active license in order to work on roofing projects valued over $500, and in most cases must be bonded.

Generally, spring or autumn is the best time of year to have your roof replaced. In the summer, Glendora's hot temperatures can slow down the project.

Your roof can impact the energy efficiency of your home. For example, a good roof allows you to use less energy to cool your home during the summer. Certain materials (such as metal) are more energy-efficient than others. In Glendora, you can reduce your carbon footprint even more by installing solar panels on your roof.

The best color for your roof is based on several factors like the color and style of your house and the local climate. For example, if you have a Spanish style home, then you'll most likely want a terracotta roof to match the style. Also, if you live in a hot climate, you (like Glendora) may want to avoid darker colors since they absorb heat, which makes your home harder to keep cool.

After your roof has been installed, check the roof's appearance. If parts are sagging or the roof isn't uniform, this is a sign that the roof was not installed well. Also, check that the flashing wasn't reused. Flashing is important to keep leaks and water damage away. Finally, you'll want to check that your contractor placed an underlayment between the shingles and sheathing of your house. This helps prevent leaks and extends the life of your roof.
