What our metal roofing service includes
Metal must still be specified as an assembly, not as a panel colour: underlayment, deck, fastening and flashing govern whether the system performs in Santa Ana wind and on a wildland-urban interface parcel.
- Full tear-off and haul-awayWe strip the existing shingles, tile, or metal panels, load them into a roll-off dumpster, and sweep the yard with a magnet for nails. Your driveway and landscaping get protected with tarps before the first shingle comes off.
- Decking inspection and repairEvery board gets checked for rot, delamination, and soft spots. Damaged sheathing is replaced and re-nailed so the panel clips have solid wood to fasten into. We show you photos of anything we replace.
- Synthetic underlaymentWe roll out synthetic underlayment over the full deck, lapped correctly at valleys and penetrations. It is the second line of defense under the panels and a required layer for most manufacturer warranties.
- Standing seam panel installPanels are cut on site with a nibbler, lifted with proper fall protection, and locked seam by seam with concealed clips. We keep courses straight with a chalk line and roofing square across long runs.
- Flashing and trimChimney, skylight, wall, and valley flashing are formed on site to fit your roof, not pulled from a universal kit. Ridge caps, eave trim, and gable trim are installed to match the panel finish.
- Final test and walkthroughWe hose-test every flashing, run a magnet sweep, and walk the roof with you using photos from the ground. You get panel written scope and a written workmanship written scope terms before we leave.

Metal roofing for businesses
Roof demand in Simi Valley is driven by inland heat and ultraviolet exposure, concentrated winter rain, and Santa Ana wind, not by snow. Rain is strongly winter-concentrated and summers are essentially dry, so valleys, flashings and drains sit dry and collect debris for months and are then tested in a handful of winter storms. Santa Ana gusts in Simi Valley have been recorded at 62 mph, as on 4-5 October 2013.

Metal Roofing in Simi Valley: what it actually is
A recent local fire was the Easy Fire, 30 October to 2 November 2019, at 1,806 acres, ignited near Easy Street and Madera Road at the westerly end of Simi Valley. The Woolsey Fire ignited on 8 November 2018 south of Simi Valley on or near the Santa Susana Field Laboratory and burned about 80 percent of that site.
Simi Valley is an incorporated city in Ventura County, incorporated on 10 October 1969, and permits inside city limits run through the City of Simi Valley Building & Safety Division, not through LADBS. The City's own FAQ states that re-roofing of more than 10 percent of the total square footage of the roof, or over 100 square feet, requires a permit. A job can therefore need a City permit without triggering other code thresholds, and the permit route, the fee line and the inspection outcome are confirmed at application, not assumed from another city's rules.
Metal roofs move with the heat, so we fasten them to move, not to fight it.

When Simi Valley homeowners call us for metal
A 1970s ranch home in Texas Tract still has its original asphalt shingles, and the owner is tired of patching them every other year.
The Woolsey Fire ignited on 8 November 2018 south of Simi Valley on or near the Santa Susana Field Laboratory and burned about 80 percent of that site.
A hillside home in Wood Ranch lost several shingles in a windstorm, and the owner wants a roof that handles the next Santa Ana event.
Simi Valley is an incorporated city in Ventura County, incorporated on 10 October 1969, and permits inside city limits run through the City of Simi Valley Building & Safety Division, not through LADBS.

How metal roofing runs in Simi Valley
Metal roofing in Simi Valley is a long-life, non-combustible option on suitable homes, not the dominant tract material. Standing-seam panels suit contemporary and hillside homes where a Class A assembly and a long service life are the priorities.
- Wood RanchHillside homes here face wind uplift on the ridgelines, so we spec concealed clips and heavier trim on the exposed planes.
- Texas TractMany 1960s and 1970s ranches still have original shingle roofs with skip-sheathing in spots, so decking repair is often part of the metal install.
- Big SkyLarger custom homes with complex rooflines need careful panel layout and on-site flashing at every valley and transition.
- Old Town Simi ValleyOlder homes close to the civic center often have mature trees, so we schedule tear-off around leaf season and sweep the yard twice.
- Santa SusanaBrush-adjacent lots here benefit from the Class A fire rating that metal panels carry, which is a real consideration for insurance.
- Summer attic temps above 140 degreesAsphalt shingles age fast in this heat, which is why so many Simi Valley homeowners switch to metal at the first replacement instead of the second.

What metal roofing costs in Simi Valley
Metal must still be specified as an assembly, not as a panel colour: underlayment, deck, fastening and flashing govern whether the system performs in Santa Ana wind and on a wildland-urban interface parcel.
Metal is also a weight and detailing question on older tract homes, so the deck and structure are checked before metal is proposed as a replacement for shingle or tile.
- Panel type and gaugeExposed-fastener panels cost less than concealed-clip standing seam, and 26-gauge costs less than 24-gauge. On a primary residence, the heavier standing seam is worth the difference in wind performance and lifespan.
- Roof complexityHip roofs, dormers, valleys, and multiple penetrations add labor and trim. A simple gable roof panels faster and cheaper than a cut-up roofline with six skylights and two chimneys.
- Decking conditionSoft or delaminated sheathing has to be replaced before the panels go on. We price the repair after tear-off and show you photos, so there is no guesswork about what got replaced.
- Tear-off layersOne layer of old shingles strips faster than three. Multiple layers mean more dumpster loads, more labor, and a higher disposal cost, all of which show up in the quote.
- Flashing and trim scopeCustom chimney and skylight flashing, new ridge vents, and upgraded eave trim add to the total. These are the details that keep the roof dry, so we price them honestly rather than leaving them out.
- Access and pitchSteep pitches and tight side yards slow the crew down and require more safety setup. A two-story hillside home takes longer to panel than a single-story ranch with a clear driveway.

Frequently Asked Questions
Simi Valley is an incorporated city in Ventura County, incorporated on 10 October 1969, and permits inside city limits run through the City of Simi Valley Building & Safety Division, not through LADBS. The City's own FAQ states that re-roofing of more than 10 percent of the total square footage of the roof, or over 100 square feet, requires a permit. A job can therefore need a City permit without triggering other code thresholds, and the permit route, the fee line and the inspection outcome are confirmed at application, not assumed from another city's rules.
A written scope follows inspection of the actual roof, because size, pitch, number of layers, material, access, and permit requirements all change the work. This website does not publish a firm price for this business; published market ranges elsewhere on this site are labelled as market data, not as a quote.
Lifespan depends on material, underlayment, ventilation, heat and wind exposure, and maintenance, so no year figure is promised here. On metal roofs, coating condition, fasteners, and flashing details are usually what inspection checks first.
The better choice depends on the house: tract or hillside position, roof pitch, weight the framing can carry, fire-zone status, and ventilation. Compare those factors for the actual roof rather than a single ‘best’ label, and confirm permit and fire-zone requirements for the parcel.
Whether a repair or a full replacement is right depends on what inspection finds: isolated damage can often be repaired, while widespread failure, deck damage, or repeated problems usually point to a larger scope. The written scope after inspection states which it is for the actual roof.
