Rusted Flashing
Rusted Flashing | Roof Inspections | Roofing | Monterey
Salt-laden sea breezes, fog, and sun can turn once-sturdy flashing into a maze of rust faster than most Monterey homeowners realize. HEP’s seasoned technicians look beyond surface stains to pinpoint hidden corrosion, loose fasteners, and gaps where wind-driven rain sneaks beneath shingles. Our detailed roof inspections combine drone imaging with hands-on expertise, so you see exactly where flashing has failed, how far moisture has traveled, and what repairs will restore watertight integrity without replacing the entire roof.
From iconic Spanish-tile bungalows near Cannery Row to cedar-clad retreats in Pebble Beach, we tailor every assessment to local architecture and coastal weather patterns. You’ll receive a clear digital report, high-resolution photos, and an easy-to-understand action plan—plus options for eco-friendly, long-lasting metal treatments that resist future rust. With HEP, preserving both curb appeal and structural peace of mind only takes one call, and it all starts with our thorough roof inspections.
FAQs
What is roof flashing and why is it crucial for Monterey homes?
Roof flashing is a thin sheet of metal—usually galvanized steel, aluminum, or copper—installed at joints, transitions, and penetrations on a roof (such as chimneys, skylights, valleys, and wall intersections). Its job is to channel water away from vulnerable seams and into the gutters. In Monterey’s marine environment, persistent fog, salt-laden air, and seasonal storms make flashing a first line of defense against leaks. When flashing fails, water can infiltrate the roof deck, attic, and interior spaces, leading to costly structural and mold damage.
How does rust develop on roof flashing in Monterey’s coastal climate?
Even when flashing is factory-galvanized, airborne salt accelerates oxidation. Moist salt particles settle on the metal, creating an electrolyte that speeds corrosion, especially on unpainted or scratched surfaces. Monterey’s frequent cycles of morning fog and strong afternoon sun produce repeated wet-dry cycles, which further degrade protective coatings. Over time, the galvanized layer erodes, exposing raw steel and allowing rust to form. Once rust starts, it expands and can lift nails, warp the metal, and open gaps where water can enter.
What are the warning signs that my roof flashing is rusting and needs inspection?
Common indicators include: • Orange or reddish discoloration along flashing edges or nail heads • Flaking, bubbling, or peeling paint on metal surfaces • Loose or lifted flashing sections, especially around chimneys and skylights • Water stains on interior ceilings or attic sheathing near roof penetrations • Musty odors in the attic after rainstorms If you notice any of these symptoms, schedule a professional inspection promptly to prevent further damage.
How often should I schedule a professional roof inspection for rusted flashing in Monterey?
Because Monterey’s salt air is highly corrosive, we recommend a full roof inspection at least once a year, ideally in late summer or early fall before the winter rains. Homes within a mile of the shoreline or with older galvanized flashing (15+ years) may benefit from bi-annual check-ups. After severe wind or rain events, it’s wise to have a quick post-storm assessment to catch new leaks or shifted metal before they worsen.
What steps are involved in your rusted flashing inspection and repair service?
1. Visual Assessment: We examine all flashing points—valleys, vents, pipes, skylights, chimneys, and sidewalls—looking for rust, lift, and failed sealant. 2. Moisture Detection: Infrared scanning and moisture meters identify hidden water intrusion behind the metal or under shingles. 3. Fastener Check: We verify that nails or screws are not corroded or backing out, replacing them with stainless or coated hardware as needed. 4. Surface Preparation: Any salvageable flashing is wire-brushed, cleaned, and treated with a rust-inhibiting primer. 5. Repair or Replacement: Severely pitted or perforated sections are replaced with new, pre-finished aluminum or stainless steel flashing rated for coastal exposure. 6. Sealant & Coating: High-grade polyurethane sealant and a marine-grade topcoat add an extra barrier against salt air. 7. Final Report: You receive photos, findings, and maintenance recommendations.
Can rusted flashing be repaired, or does it always need to be replaced, and what costs should I expect?
If rust is limited to surface oxidation without deep pitting or holes, we can often restore the flashing by cleaning, priming, and coating it, costing $200–$400 for a typical problem area. However, once metal has thinned, warped, or separated from the roof deck, replacement is safer and more economical long-term. Full flashing replacement around a chimney or skylight usually ranges from $600 to $1,200, depending on accessibility and material (standard galvanized steel vs. premium stainless or copper). A comprehensive inspection lets us determine the most cost-effective solution while safeguarding your home against future leaks.
