What is the cost of installing a new roof in Los Altos?
When you're ready to redo your roof, take your time selecting the right material. Roofing options vary in price, longevity and durability. Concrete, metal and slate rank among the toughest roofing materials on the market.
In Los Altos, installing a metal roof costs $18,551, on average, for a 2,000-square-foot home. Nationally, the average cost for a metal roof is around $17,521 for a 2,000-square-foot home*.
*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 Los Altos
There are several ways you can save money on your roof replacement.
- Check your homeowners insurance: Homeowners insurance usually covers roof repairs due to damage from fires, fallen trees, storms and certain other hazards. Check the exact coverage information and limits of your policy.
- Compare quotes from multiple sources: Carefully weigh factors like rates, qualifications, materials, availability and services before choosing a roofer in Los Altos.
- Conduct routine roof maintenance: Once your roof repairs are done, prioritize routine inspections and maintenance. This helps you identify and prevent future issues. Missing a minor issue can escalate into more extensive and expensive damage.
- Invest in preventive measures: You can invest in preventive measures such as adding extra insulation or improving ventilation to decrease future repair needs and energy bills.
- Schedule roofing services during good weather if possible: For the best pricing, book roof repairs during off-peak periods when roofers aren't as busy. However, avoid the wet season because bad weather can raise the cost. Scheduling repairs during a dry period in an off-peak season can help you save the most money.
What are the signs that you need a new roof?
You may need to bring in a roofer if you see the following signs:
- Water in your attic: Your attic's insulation should be dry, and you shouldn't see any visible roof gaps. Gaps indicate an issue likely needing repairs.
- Curled shingles: Shingles that are broken, missing or curled let moisture into your roof, which can cause structural problems through rotting in the rafters and decking.
- Discoloration: You probably have a leak if you see dark discoloration on the undersides of your rafters or decking.
- Mildew or mold Black mold and powdery mildew is never a good sign. These can signify roof leaks, lead to health problems and damage your home.
- Rust: Rust on your flashing or fasteners undermine weatherproofing and the integrity of your home.
- Visible sagging: Your roof sagging is a warning sign that your roof may collapse. Reasons for sagging include mechanical equipment, dense clay tiles, concrete pavers, excess insulation or overwhelmed drainage. Pooling water and warped sheathing can also worsen the problem by reducing your roof's drainage.
What are common roofing issues?
Your roof is bound to experience issues at some point, even with proper maintenance. You can get ahead of major damage through regular inspections and maintenance.
Some typical roofing issues you may encounter while performing your own visual inspection include the following.
Damaged shingles
One of the most frequent roofing problems you may find is shingle damage or wear and tear. While asphalt shingles generally last 20–30 years, exposure to harsh weather and ultraviolet radiation erodes them over time, leading to cracking or lifting. Warped, broken or missing shingles let in moisture that can lead to leaks, mold and structural decay.
Flashing failures
Flashing refers to the metal sheets around the valleys, joints, skylights, vents, chimneys and dormers of a roof. Its primary function is to prevent rain, snowmelt and runoff from entering the home by deflecting and redirecting it away from vulnerable seams and transition points. Improperly installed or worn flashing can become a common entry point for water into your home. Check for flashing failure when you notice peeling paint, moisture stains, leaks coming from joints, drips from ceilings that align with flashing seams, or sagging areas.
Leaks
Leaks may develop in areas such as seams, protrusions and flashing around chimneys, skylights, valleys and vent pipes where roof planes intersect. These watertight joints may shift and allow water in due to expansion and contraction from temperature changes. Early identification and repair prevent mold and decay.
Poor insulation
Attics with poor insulation lead to extreme temperatures in your home. This causes issues such as high energy bills, ice dams, leaks, damaged rafters and mold. Upgrading to proper insulation for the local climate can yield substantial energy savings.
Standing water
Standing water occurs when water doesn't drain from your roof properly due to debris or low areas. Your roof can begin rotting due to moisture saturation if the water isn't removed within 48 hours. It also places considerable weight stress and could indicate the need for replacing your roof surface to fix the slope or drainage. Clear away debris regularly and make sure there's proper drainage to prevent these issues.
How long are roofs supposed to last?
Installation quality is the most important factor that affects how long your roof will last, but other factors such as your climate, roof material and maintenance frequency 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, and traditional three-tab shingles generally last 15–20 years. Shake roofs, wood shingles and slate have an average life span of 20–25 years, but they tend to be vulnerable to mold, rot and insect damage.
A metal roof's life span is 40–70 years or more. Concrete roofs generally last 50 years or up to a century with proper maintenance. A slate roof can last for 100 years or more if properly maintained.
