What Our Tile Roofing Service Includes
New tile is not a like-for-like swap for shingle. It is heavier, it needs a deck and structure that can carry it, and the City's submission for new tile includes an ICC report under the attachments, so the permit route is confirmed before ordering.
- Full Roof InspectionWe inspect the tile, underlayment, flashing, battens, decking, and ventilation. You get photos and a written report of what we found, whether the job is a repair or a full re-lay.
- Tile Salvage and Re-LayWe pull the field tile, stack it, and save every usable piece. On most Simi Valley re-lays we reuse 80 to 90 percent of the tile, which lowers your material cost and keeps the original look.
- New Underlayment and FlashingNew underlayment goes down over the decking, with ice and water shield at valleys and penetrations. We replace flashing at chimneys, walls, and vents so the waterproofing layer is complete.
- Decking Repair as NeededIf we find dry rot in the sheathing, we cut it out and replace it before the new underlayment goes down. We photograph the damage and price the repair before continuing.
- Ridge Caps and VentilationWe re-set ridge and hip caps, fasten them to code, and check that ridge vents and attic ventilation are working. A tile roof needs airflow under it to manage heat and moisture.
- Cleanup and Final WalkWe magnet-sweep for nails, clear the driveway and walkways, and walk the roof with you when we are done. You get final photos and a note on what to watch going forward.

What Tile Roofing in Simi Valley Actually Involves
For a single-family re-roof in CEC Climate Zone 9, the Title 24 Part 6 prescriptive cool-roof values are an aged solar reflectance of at least 0.20 with thermal emittance of at least 0.75, or an SRI of at least 16, on steep slopes of 2:12 or more, and at least 0.63 with emittance of at least 0.75, or an SRI of at least 75, on low slopes under 2:12. That requirement is triggered when more than 50 percent of the roof area is replaced, which is a different threshold from the City permit trigger, and the parcel's zone should be checked with the CEC zone finder before a product is specified.
Simi Valley contains High and Very High Fire Hazard Severity Zone parcels, but it is not correct to say that all of Simi Valley is Very High. The parcel's zone must be checked in the CAL FIRE / VCFD Fire Hazard Severity Zone viewer, and on a wildland-urban interface parcel the current citation is Title 24 Part 7, the California Wildland-Urban Interface Code, not the retired CBC Chapter 7A. On such a parcel a Class A fire-rated roof assembly is required.
Tile roofs fail at the layer you cannot see, so we fix the underlayment first.

When Simi Valley Homeowners Call Us for Tile
You bought a 1980s Simi Valley home with original tile and no record of the underlayment ever being replaced.
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 windstorm walked a dozen tiles out of line and you can see exposed underlayment from the yard.
For a single-family re-roof in CEC Climate Zone 9, the Title 24 Part 6 prescriptive cool-roof values are an aged solar reflectance of at least 0.20 with thermal emittance of at least 0.75, or an SRI of at least 16, on steep slopes of 2:12 or more, and at least 0.63 with emittance of at least 0.75, or an SRI of at least 75, on low slopes under 2:12.
You are preparing to sell and the buyer's inspector flagged the tile roof as near end of life.
That requirement is triggered when more than 50 percent of the roof area is replaced, which is a different threshold from the City permit trigger, and the parcel's zone should be checked with the CEC zone finder before a product is specified.
Your tile roof has a flat section over the garage that is leaking where it meets the tile.

How Tile Roofing Runs in Simi Valley
Tile is the hillside and master-planned story in Simi Valley: concrete and clay tile on Wood Ranch, Big Sky and foothill homes, where the tile's weight, profile and colour shape both the structure and the street.
- Wood RanchLarger tile roofs on two-story homes, often with complex valleys and multiple chimneys that need careful flashing work.
- Central Simi ValleyMany 1970s and 1980s homes with original tile now due for underlayment replacement.
- Old Town Simi ValleyOlder homes where tile may sit over multiple roof layers, so we check decking condition before re-laying.
- Indian HillsElevated lots with more wind exposure, so we pay extra attention to ridge cap fastening and tile alignment.
- Summer heat above 100 degreesAccelerates underlayment drying and brittleness. We inspect the felt condition closely on any roof over 20 years old.
- Santa Ana wind eventsLifts poorly fastened tile and ridge caps. We verify fastening patterns and re-secure loose pieces as part of every job.

- Roof size and pitchLarger and steeper roofs take more labor, more safety setup, and more material. A steep two-story tile roof in Wood Ranch takes longer to strip and re-lay than a low-slope single-story roof.
- Tile salvage percentageEvery tile we can reuse lowers your material cost. If the field tile is in good shape, we may salvage 80 to 90 percent, which is a significant savings versus buying all-new tile.
- Underlayment conditionIf the underlayment is the only failure, the job is a re-lay. If water has reached the decking, we add decking repair to the scope, which increases labor and material.
- Flashing and penetration countChimneys, skylights, vents, and valleys each need flashing work. A roof with multiple penetrations takes longer and costs more than a simple gable roof with none.
- Access and stagingTight lots, steep driveways, and landscaping near the house affect how we stage tile and equipment. Easy access keeps labor hours down; difficult access adds time.

Frequently Asked Questions About Tile Roofing
Tile is the hillside and master-planned story in Simi Valley: concrete and clay tile on Wood Ranch, Big Sky and foothill homes, where the tile's weight, profile and colour shape both the structure and the street.
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 tile roofs in Simi Valley, the tile often outlives its underlayment, which is why lift-and-relay is a separate scope from new tile.
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.
