In San Jose, the price for putting a metal roof on a 2,000-square-foot home runs about $18,551, compared to the national average of $17,521.
*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 can you save money on a San Jose roof repair?
There are several things you can try to save money on roof repairs.
- Check your homeowners insurance: Consult your home insurance policy to determine whether it will help pay for the repairs. Depending on the cause of damage, such as storms or fallen branches, your insurance policy may cover the cost of the repairs.
- Compare quotes from multiple sources: Get quotes from multiple roofing companies in San Jose. Review their rates, services and availability to make sure you get the best repairs.
- Conduct routine roof maintenance: Routine inspections and maintenance allow you to catch minor problems that can turn into more extensive and expensive ones.
- Invest in preventive measures: Look into preventive measures such as installing insulation and improved attic ventilation. These help minimize moisture damage and future repair needs while also lowering energy bills.
- Schedule repair services during good weather if possible: Roofing contractors may offer discounts during slower periods. Avoid scheduling work during the rainy season as bad weather may raise the cost.
What are signs you need roof repair?
A certified roofer can inspect and fix any issues with your roof. You may need to contact an expert if you spot the following:
- Water in your attic: Your attic's insulation should be dry, and there shouldn’t be visible gaps in your roof. If you notice gaps, you have a problem and likely need repairs.
- Curled shingles: Damaged shingles, whether curled, broken or missing, can let moisture into your roof. This can cause the rafters and decking to rot, leading to potential structural issues.
- Discoloration: Your roof is likely leaking if you spot dark stains on the undersides of your rafters or decking.
- Mold or mildew Powdery mildew and mold on your roof can lead to health issues and structural damage. These can indicate roof leaks, which need to be addressed quickly.
- Rust: Rust from flashing or fasteners indicate deterioration, and rust and corrosion compromise weatherproofing and the integrity of your home.
- Visible sagging: Roof joists, sheathing and rafters can sag due to mechanical equipment, concrete pavers, excess insulation, overwhelmed drainage or dense clay tiles. Visible sagging is a warning sign of potential collapse, so get a roof inspection promptly to find the issue.
What are common roofing issues?
Even properly maintained roofs eventually run into issues after years of wear. You can get ahead of major repairs through regular inspections and maintenance.
Look out for the following problems during your visual inspection.
Damaged shingles
One of the most frequent roofing problems you may face is damaged or worn shingles. Exposure to extreme weather can erode your roofing material faster and crack or lift the shingles. Damaged shingles let moisture seep in, potentially resulting in mold, leaks and structural decay.
Flashing failures
Flashing is the metal sheets around the seams and transition points of your roof. Its purpose is to shield these areas of your roof from rain, snowmelt and runoff. However, if the flashing isn’t properly installed or has worn down over time, it can create a common pathway for water to enter your home. Check for flashing failure when you see signs of sagging areas, moisture stains, peeling paint, drips from ceilings that align with flashing seams or leaks coming from joints.
Leaks
Leaks may develop in areas such as seams, protrusions and flashing around valleys, vent pipes, chimneys and skylights where roof planes intersect. These watertight joints may shift and allow water in due to expansion and contraction from temperature changes. Repairing leaks as soon as possible helps avoid more costly damage down the line.
Poor insulation
Attics with too little insulation cause extreme temperatures in your home. This causes problems such as ice dams, mold, leaks, damaged rafters and high energy bills. Upgrading to proper insulation suitable for the local climate can yield substantial energy savings.
Standing water
Standing water usually happens when your roof's decking has low spots and debris accumulation. This causes long-lasting water after storms. Your roof can get saturated and begin to rot if not removed within 48 hours. It also places major weight stress on your roof. Standing water can indicate a need to replace the roof surface due to a slope or bad drainage. Clear out debris on a regular basis and make sure there's proper drainage to prevent these problems.
How long are roofs supposed to last?
Several factors, such as your climate, quality of installation, maintenance frequency and roof material affect your roof's life expectancy. Installation quality plays the biggest role in determining how long your roof will last.
Asphalt shingles last 20–30 years on average, but the type of shingle will affect the life span. Architectural shingles can last up to 25–30 years, and traditional three-tab shingles generally last 15–20 years. Properly maintained shake roofs or wood shingles can last about 20–25 years. However, they may be vulnerable to insect damage, mold and rot.
Most metal roofs last 40–70 years or more. Concrete roofs can last 50 years or more and sometimes last over a century with proper maintenance. A slate roof can last for over a century if properly maintained.
