Today's Homeowner looks at dozens of datapoints on roofers to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
For a project as substantial as roof replacement, cost matters. Below is the typical price range to replace a roof on a 1,500 square foot home in Diamond Bar. We also compare prices for popular roofing materials.
A new roof installation is a large home renovation that can cost over twenty thousand dollars total. It's crucial to research and find a highly reviewed and recommended roofing company for the job. Here are some important considerations for selecting a roofer.
Though most homeowners don't think about their roof every day, it plays a vital protective role for your home. Keep watch for these common signs that your roof may need inspection and repairs from a professional roofer.
The age and material of your roof play a big role. Asphalt shingles, the most popular roofing material for homes, normally last about around 20–25 years. If your roof is nearing or past this lifespan, have it inspected to see if complete replacement is necessary.
One of the clearest signs of roof trouble is water leaks. Stains on your insulation, walls, or ceilings, or in your attic likely indicate water seeping through damaged or worn shingles. Even small leaks can be an issue, as they can cause mold growth and further damage to your roof.
If you can see roof deck boards or sheathing under shingles, it means that those shingles are curling or losing their seal. This means the shingles likely need replacement. Shingles need to lie flat to stop water from getting into your home.
Carefully examine your shingles from the ground or a safely-placed ladder. Look for any shingles that are cracked or have lost their protective granule coating. Over time, environmental factors like storms can cause surface damage. To keep your roof in good repair, you should replace any missing shingles or ones with gaps.
Roof flashing seals off valleys, vents, chimneys, and other areas that pass through the roof. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any flashing problems fixed right away.
An uneven roofline may indicate a structural issue that requires professional evaluation. Without properly addressing and resolving the issue, a sagging roof will get worse over time.
The best type of roofing material for your home in Diamond Bar will depend on things like your budget and how often you're willing to do maintenance.
Metal costs more but is more durable, while asphalt will be cheaper up front but won't last as long. Metal, clay, and treated wood tend to be the best options if your part of Diamond Bar is at higher risk of wildfire damage. In Diamond Bar, winters can be cold. This can make a wood roof, with its superior insulation, a better choice for you. On the other hand, clay roofs can be beneficial during the summer, as they reflect Diamond Bar's bright sunlight and save you money on cooling costs.
Licensing in California is handled by the Department of Consumer Affairs Contractors State License Board. Contractors must have an active license to work on roofing projects valued above $500, and in most cases must be bonded.
It generally takes between one and five days to replace a roof. Variables that could influence this timeline include the size of your roof, how easily accessible it is, and what the weather is like in Diamond Bar during the timeframe. .
Your roof can impact how energy-efficient your home is. For example, a good roof allows you to use less energy to cool your home during the summer. Some materials (like metal) are more energy-efficient than others. In Diamond Bar, you can reduce your carbon footprint even more by installing solar panels on your roof.
Depending on which contractor you use, some roof replacement costs may be covered by your home insurance. Some insurance companies may have preferred contractors. It may also be easier to have costs covered if the damage was caused by a covered weather event, such as a tornado. You can talk to your home insurance company to find out if they have preferred contractors, and what costs might be covered.
How soiled your roof is, in addition to what it's made of, will determine how your contractor cleans it. Power washing can be used on some roofs, but it isn't recommended for materials like asphalt tiles. "Soft washing" uses tools like brooms and brushes, plus chemicals like bleach and detergent.
