24/7 Roof Tarping Contractor in Los Angeles That Stops Leaks Before They Spread

Water getting past the roof covering and into the attic or living space during heavy rain. On tile roofs, the tiles usually look intact. The real failure is the felt underlayment underneath, which has dried out, cracked or rotted through over decades.

LA's long dry season hides this problem. Felt under clay and concrete tile breaks down from heat and age, and nobody notices because it barely rains from May to October. Then an atmospheric river sends inches of water across the roof in hours, and every weak spot leaks at once. Thousands of homeowners find leaks the same weekend, roofers book out for weeks, and a tarp becomes the only realistic way to stop the damage from getting worse.

• Brown water stains spreading on ceilings
• Dripping from light fixtures or ceiling vents
• Damp or matted attic insulation
• Bubbling or peeling paint near the ceiling line
• Musty smell after the first storm of the season
• Water running down interior walls

We see this most on 1970s–2000s tile roofs in Diamond Bar, Walnut, Calabasas and Santa Clarita, and on older Spanish Revival homes in Glendale, Pasadena and Alhambra. Calls spike within 24 hours of the season's first major storm.

Our fix: We tarp over the leak zone without cracking more tile, lap the tarp past the ridge, batten it down, and document the interior damage for your insurer.

Shingles that have been torn loose or creased, or tiles that have shifted and cracked, during high winds. This exposes underlayment or bare decking and leaves open paths for water to get into the roof.

Santa Ana winds regularly gust 40–70+ mph through canyons and foothill passes. In the Antelope Valley, wind is close to constant. Shingles that have gone brittle after years of 9–11 UV exposure lose their seal strips and peel back easily. Tile that was set with dried-out mortar or corroded fasteners slides out of place. The damage often happens during dry Santa Ana events, so you may not find out about it until the next rain.

• Shingles or tile pieces in the yard or gutters
• Visible gaps or exposed felt from the street
• Lifted shingle tabs along ridges and edges
• Granules collecting at downspouts
• Rattling or flapping sounds on the roof during wind

This is common in Santa Clarita, La Cañada Flintridge, Sierra Madre, Agoura Hills and the San Gabriel foothills near Azusa, and in high-desert Lancaster and Palmdale. Coastal homes see it too, where salt air has weakened fasteners.

Our fix: We cover the damaged sections with a heavy-duty tarp secured by 2x4 battens and sandbags, so the next Santa Ana doesn't rip it off.

A falling branch or whole tree that breaks through roofing, sheathing and sometimes rafters, leaving a hole open to the weather and possibly weakening the structure.

Older LA neighborhoods are full of mature eucalyptus, pine, ficus and sycamore trees. Many were planted decades ago, right next to houses. Eucalyptus is notorious for dropping heavy limbs in wind, and saturated soil during atmospheric rivers lets whole trees topple. These impacts usually happen in the middle of a storm, which is exactly when the house can least afford an open hole.

• Visible branch or debris on the roof
• Daylight through the attic sheathing
• Sagging ceiling below the impact point
• Cracked rafters or broken drywall
• Rain coming directly into a room

We see this often in tree-lined Pasadena, San Marino, Arcadia, South Pasadena, Burbank and Long Beach, and in hillside neighborhoods of the Santa Monica Mountains and Verdugos where big trees overhang homes.

Our fix: Once the debris is cleared, we board-and-tarp the opening, seal its edges, and photograph the structural damage for your adjuster and the permanent repair crew.

Standing water on flat or low-slope roofs that gets into seams, blistered membranes, clogged drains and parapet flashing. Over time it soaks the decking and leaks into units or commercial space below.

LA has a huge number of flat roofs: built-up tar-and-gravel, modified bitumen, torch-down and old rolled roofing. Summer heat blisters and cracks them. Scuppers and drains fill with leaves and debris all through the dry season. When heavy rain arrives, water pools behind parapets, finds every crack, and pours into apartments. Landlords then face tenant habitability obligations right away.

• Water pooling 48+ hours after rain
• Blistered, cracked or alligatored membrane
• Clogged scuppers or roof drains
• Leaks along walls near parapets
• Stains in top-floor units or suites

This is typical on dingbat apartments in Santa Monica, Culver City and West Hollywood, on mid-century homes, and on industrial and commercial roofs in Vernon, Commerce, Industry, Santa Fe Springs, Bell and Bell Gardens.

Our fix: We anchor the tarp without puncturing the membrane, position it to shed water toward the drains, and clear clogged scuppers to reduce ponding.

Roofs that are partly burned, scorched or penetrated by embers, or covered in ash and soot. They may still look standing but can no longer keep water out, and the salvageable structure underneath is at risk.

The January 2025 Palisades and Eaton fires destroyed thousands of structures and left many more partly damaged in Pacific Palisades, Malibu, Altadena, Pasadena and Sierra Madre. Winter rain on a compromised roof washes ash and soot into insulation and drywall, turning a repairable home into a gut job. Burn zones may have restricted access, debris-removal protocols, and insurers who expect prompt mitigation.

• Scorched or melted shingles or vents
• Ember holes in roofing or skylights
• Heavy ash on the roof and in gutters
• Smoke odor in the attic
• Charred fascia or eaves

This is concentrated around the Palisades and Malibu, the Altadena/Eaton footprint, and the Pasadena and Sierra Madre foothills. Most of these homes sit in Very High Fire Hazard Severity Zones, where permanent re-roofs will need Class A materials.

Our fix: We weatherproof damaged areas before rain arrives, coordinate around access restrictions, and document the condition thoroughly for fire and FAIR Plan claims.

Tiles cracked or shifted by ground shaking, plus chimneys and flashing that have separated from the roof, creating hidden leak points that may not show up until the next rain.

The 1994 Northridge earthquake showed how a single quake can crack tile and chimneys across the region. Even moderate shaking can loosen mortar-set tile and break the seal where an older brick chimney meets the roof. Many pre-1960 homes still have original unreinforced masonry chimneys.

• Visible cracked or slipped tiles
• Gaps between chimney and roofline
• Leaks around the fireplace wall
• Loose bricks or mortar debris
• New ceiling cracks after shaking

This shows up most in San Fernando Valley neighborhoods near Burbank and San Fernando, on Craftsman and Spanish homes in Highland Park and Silver Lake, and on older homes in Whittier and Monterey Park.

Our fix: We tarp the affected slopes and seal the chimney area temporarily, then document the damage for earthquake or homeowners coverage review.

Slow leaks where a newer addition, ADU or garage conversion meets the original roof, usually caused by poor flashing or mismatched slopes that let water get under the overlap.

LA's ADU boom and decades of informal additions have put thousands of roof junctions on top of older homes. Many were flashed cheaply or tied low-slope sections into steeper roofs. They often get by for years of light rain, then start leaking during a sustained atmospheric-river soaking.

• Stains where old and new rooms meet
• Damp baseboards along an addition wall
• Gaps in step or counter flashing
• Moss or debris collecting in valleys
• Leaks only during long, heavy storms

We find these on postwar tract homes in Lakewood, Downey, Bellflower, Artesia, Baldwin Park and El Monte, and on infill lots in South LA, Inglewood and Hawthorne with garage conversions.

Our fix: We tarp the junction so water drains past the joint, which buys time for a roofer to re-flash it properly.
