Across the country, installing a metal roof on a 2,000-square-foot home runs around $17,521, compared to approximately $17,177 in San Dimas*.
*Local costs were determined using RSMeans project estimates combined with local labor costs from the Bureau of Labor Statistics and cost data from home improvement stores. We also interviewed homeowners from around the country to validate local costs.
How to save money on roof installation in San Dimas
Getting your roof replaced is a major expense. Here's how you can cut down on the cost.
- Check your homeowners insurance: Read over your home insurance policy to determine whether it will help pay for a roofing company. Depending on the reason for the damage, such as fallen branches or storms, your insurance may cover the cost.
- Compare quotes from multiple sources: Compare the prices and services offered by several roofing companies in San Dimas. This allows you to make an informed decision.
- Conduct routine roof maintenance: Conduct routine roof inspections and maintenance after getting your roof replaced. Spotting minor issues early prevents more serious damage requiring pricey repairs later on.
- Invest in preventive measures: Look into preventive measures such as increased insulation and improving ventilation. These help minimize moisture damage and future repair needs while also bringing down energy bills.
- Schedule roofing services during good weather if possible: For the best pricing and conditions, plan roof repairs during slower periods when contractors aren't as busy. However, avoid the rainy season because inclement weather can drive up the cost. Your best bet is to try and schedule repairs during a dry period in an off-peak season.
What are the signs that you need a new roof?
You may need to bring in a roof repair if you notice the following signs:
- Water in your attic: The insulation in your attic should be dry, and there shouldn’t be visible gaps in your roof. If you notice gaps, you have an issue and likely need repairs.
- Damaged shingles: Damaged shingles, whether curled, missing or broken, can allow moisture to seep into your roof. This can cause the decking and rafters to rot, leading to potential structural issues.
- Discoloration: Dark stains on the undersides of your rafters or decking signals your roof likely has a leak and needs repairs.
- Mildew or mold: Powdery mildew and mold are signs of roof leaks. These can lead to health issues and structural damage, so you should address them as soon as possible.
- Rust: Severe rust can lead to curling, warping or holes in your flashing or fasteners. This undermines your home's weatherproofing and structural integrity.
- Visible sagging: Roof sheathing, rafters and joists can sag due to concrete pavers, overwhelmed drainage, mechanical equipment, excess insulation or dense clay tiles. Visible sagging is a warning that your roof may collapse, so get a roof inspection as soon as possible to figure out the issue.
What are common roofing issues?
Wear and tear eventually takes a toll on your roof. Proactive visual inspections and roof maintenance are essential in catching issues before they escalate and lead to costly repairs.
A few common roofing issues to look for during an inspection include the following.
Damaged shingles
A major roofing problem is damaged shingles. Asphalt shingles, a popular material for roofs, usually last about 20–30 years, but extreme weather can lead to cracking or lifting. Damaged shingles let moisture seep in, potentially causing structural decay, leaks and mold.
Flashing failures
Flashing is the metal sheets around the seams and transition points of your roof. Its primary function is to protect these parts of your roof from rainwater and runoff. Improperly installed or deteriorated flashing can become a common entry point for water into your home. Check for flashing failure when you see signs of moisture stains, leaks coming from joints, drips from ceilings that align with flashing seams, sagging areas, or peeling paint.
Leaks
Common leak sites are joints and flashing around skylights, roof penetrations and chimneys. Temperature changes and aging materials cause these joints to open gaps, allowing water intrusion. Repairing leaks as soon as possible helps avoid more expensive damage down the line.
Poor insulation
Insufficient attic insulation can cause expensive roofing problems and uncomfortable temperatures in your home. Making sure your attic is properly insulated for the local climate is a must for energy efficiency.
Standing water
Pooling water usually happens because of accumulated debris or low areas in your roof's decking. This can lead to pooled water after storms, which can cause damage. If it persists for more than 48 hours, it can result in moisture saturation and rot in roof components. It also puts substantial weight stress and could indicate the need for replacing your roof surface to correct the slope or drainage. Cleaning debris regularly and ensuring proper drainage helps stop these issues from happening.
How long are roofs supposed to last?
Installation quality impacts how long your roof will last the most, but other factors such as your roof material, maintenance frequency and climate will also play a role.
Asphalt shingles last 20–30 years on average, but the kind of shingle will affect the life span. Architectural shingles can last up to 25–30 years, while traditional three-tab shingles typically last 15–20 years. Well-maintained wood shingles or shake roofs can last approximately 20–25 years. However, they are prone to insect damage, mold and rot.
A metal roof's life span is 40–70 years or more. Concrete roofs last around 50 years, but sometimes last over a century with proper maintenance. Slate roofs can last for 100 years or more.
