A new roof is one of the best investments you can make in your home. Beyond preventing costly water damage, a quality roof replacement increases home value by $12,000-$20,000, improves energy efficiency by 15-25%, and provides peace of mind for decades.
At EHL Roofing, we've replaced over 800 roofs across 25 Bay Area cities in the past 5 years. We understand the unique challenges of each microclimate: coastal fog erosion in Pacifica, intense UV exposure in South Bay, wind uplift in the Peninsula hills, and seismic considerations throughout the region.
Our process eliminates the traditional frustrations of roof replacement. Using drone technology, we provide laser-accurate measurements (±2% accuracy) so your quote is precise—no surprise "we need more materials" costs mid-project. Our AI-powered estimating delivers detailed quotes in 2 hours, not 2 weeks. And with multiple financing partners offering competitive rates from 7.99% APR, you can afford the roof you need today.
Every replacement includes: complete tear-off to roof deck (no overlays that hide problems), new synthetic underlayment, premium shingles of your choice, upgraded ventilation if needed, thorough cleanup with magnetic nail sweep, and a 10-year workmanship warranty backed by $1M insurance. We don't cut corners—we build roofs that last.

10 Common Issues We Fix
When we tear off your old roof, we often discover issues invisible from the surface. Here are the most common problems we fix during Bay Area roof replacements:
Rotted or Damaged Roof Decking
HIGHUndetected leaks cause plywood or OSB decking to rot. Must be replaced before installing new roof.
Symptoms:
- Soft spots when walking on roof
- Sagging areas visible from ground
- Water stains on attic ceiling
- Previous leak history
- Roof age over 25 years
How We Help:
During tear-off, we inspect 100% of decking. Replace damaged sections with matching thickness plywood or OSB. Average decking replacement: $600-$2,000 depending on extent (quoted separately if found).
Inadequate or Failed Underlayment
MEDIUMOld roofs often have felt paper underlayment that deteriorates. Modern synthetic underlayment lasts 30+ years.
Symptoms:
- Roof age over 20 years
- Previous leaks
- Brittle or torn underlayment visible during tear-off
How We Help:
All our replacements include premium synthetic underlayment (not cheap felt paper). Provides superior waterproofing and tears less during installation. Included in every quote.
Poor Ventilation System
MEDIUMMany older roofs lack proper ventilation, causing premature aging and energy loss.
Symptoms:
- Excessive attic heat in summer
- Ice dams in rare Bay Area winter freezes
- Premature shingle aging
- High cooling bills
- Mold or mildew in attic
How We Help:
We calculate required ventilation per building code. Install ridge vent and adequate soffit vents. Proper ventilation extends roof life by 5-10 years. Ventilation upgrades: $800-$1,500.
Improper Flashing Installation
HIGHMost roof leaks stem from flashing failures, not shingle issues. Old flashing must be replaced.
Symptoms:
- Water stains near chimneys or skylights
- Rust on existing flashing
- Previous leak repairs with tar or caulk
- Flashing visibly separated from roof
How We Help:
Complete flashing replacement around all chimneys, skylights, vents, walls. Use step flashing (proper method) not continuous pieces. Premium materials prevent future leaks. Included in replacement.
Overlayered Roofs (Multiple Layers)
HIGHSome old roofs have 2-3 layers of shingles. Building code now prohibits overlays in most California cities.
Symptoms:
- Roof appears extra thick
- Bumpy or uneven surface
- Extra weight on structure
- Previous roof was "overlay" not tear-off
- Home built before 2000
How We Help:
We always tear-off to roof deck (no overlays). Remove all old layers. Inspect structure. Install one perfect layer. This reveals and fixes hidden problems. Tear-off included in every quote.
Valley Problems
HIGHValleys channel water and wear out faster. Old valleys may be improperly constructed.
Symptoms:
- Water stains along valley line inside
- Valley rust or deterioration
- Closed valley (shingles woven) showing wear
- Previous valley repairs
How We Help:
Replace all valleys with premium metal flashing. Recommend open valley (exposed metal) for Bay Area climate—lasts longer than closed valleys. Valley replacement included in quote.
Structural Issues
HIGHSagging roof lines, broken rafters, or inadequate support discovered during tear-off.
Symptoms:
- Visible sag in roof line
- Cracks in interior walls or ceilings
- Doors or windows sticking
- Bouncy feel when walking on roof
- Home built before 1960
How We Help:
If structural issues found during tear-off, we stop and provide separate quote for repairs. Require structural engineer approval before proceeding. Safety first—we never install new roof over structural problems.
Improperly Installed Previous Roof
HIGHMany roofs were installed incorrectly: wrong nails, improper overlap, no starter strip, etc.
Symptoms:
- Premature failure despite "new" roof
- Widespread shingle blow-offs
- Visible nails on surface
- Misaligned shingles
- Previous installer no longer in business
How We Help:
We follow manufacturer specifications exactly. Use correct nails, spacing, overlap. Licensed contractor ensures code compliance. Proper installation = 30+ year lifespan. Manufacturer warranty requires proper installation.
Pest Damage (Rodents, Birds)
MEDIUMRats, squirrels, or birds sometimes nest in attic or damage roof penetrations.
Symptoms:
- Scratching sounds in attic
- Droppings in attic
- Damaged vent screens
- Holes chewed in fascia or soffits
- Nearby trees touching roof
How We Help:
During tear-off, we identify and seal all pest entry points. Install pest-proof vent screens. Recommend attic remediation if heavy infestation. Pest-proofing: $200-$600 additional.
Seismic Considerations
LOWBay Area homes need proper rafter-to-wall connections for earthquake resistance.
Symptoms:
- Home built before 1990
- No visible hurricane ties or straps
- Older construction methods
- Foundation or structural updates done previously
How We Help:
While replacing roof, we can install hurricane ties/straps connecting rafters to walls. Not required by current code for re-roofing, but recommended for seismic safety. Seismic upgrades: $800-$2,000.

10 Factors That Affect Your Price
$12,000-$35,000 (typical residential)
Understanding what drives cost helps you make informed decisions
Roof Size (Square Footage)
HIGHRoofing is priced per "square" (100 sq ft). Small homes (1,200 sq ft roof) cost $12K-$15K. Large homes (3,000+ sq ft roof) cost $25K-$35K. Our drone measurements are ±2% accurate for precise quotes.
Material Choice (4 Tiers)
HIGHMaterial choice has the biggest impact. 3-tab shingles: $350/square. Standard architectural: $450/square. Premium architectural: $550/square. Metal/tile: $1,000-$2,000/square.
Roof Complexity
HIGHSimple gable roofs install faster. Complex roofs with multiple valleys, dormers, skylights, and pitch changes require more labor and materials. Can add 20-40% to cost.
Roof Pitch (Steepness)
MEDIUMSteep roofs (8/12 pitch+) require safety equipment and scaffolding. Adds 15-25% to labor costs. Very steep roofs (12/12+) may need specialized equipment.
Number of Layers to Remove
MEDIUMSingle layer tear-off: standard pricing. Two layers: add $1,500-$3,000. Three layers (rare): add $3,000-$5,000. More labor and disposal costs.
Decking Repairs
HIGHIf we discover rotted decking during tear-off, must be replaced before re-roofing. Averages $8-$12 per sq ft. Can add $600-$3,000 depending on extent. Always quoted separately if found.
Ventilation Upgrades
MEDIUMProper ventilation extends roof life. Ridge vent + soffit vents: $800-$1,500. Highly recommended if current ventilation inadequate. Reduces energy bills 10-15%.
Skylight or Chimney Quantity
MEDIUMEach penetration requires custom flashing. Skylights: $200-$400 each. Chimneys: $400-$800 each. Multiple vents: $100-$200 total. Affects labor time.
Location (City)
LOWWe charge the same pricing in all 25 Bay Area cities. No travel fees within our 40-mile radius. Permit costs vary by city ($150-$400) but we handle this.
Disposal & Cleanup
LOWDumpster rental and debris disposal included in every quote. Typically $800-$1,200 depending on roof size and number of layers removed.
