As a roofing contractor for Rowland Heights, CA, we drive about 35 minutes (17 miles) east from our base on Rosemead Blvd, out the Pomona Freeway. Rowland Heights had 48,231 residents in 2020 and is unincorporated, so LA County Public Works Building & Safety, not a city hall, issues its roof permits.
What sets it apart is the terrain. Homes step up the slopes of the Puente Hills on curving streets, and a large share wear concrete or clay tile instead of shingle. Down on Colima Road, the busy business district runs on shopping plazas with flat roofs behind their facades.
Concrete tile on the Puente Hills slopes: what wears out
Most hillside streets here were developed between the 1970s and the 2000s, and concrete tile is their standard roof. The tile itself lasts a long time. The underlayment beneath it does not, and on many of these homes the original felt is now brittle, torn at the eaves and letting water through at valleys and around chimneys.
- Cracked or slipped tiles from wind, foot traffic or old satellite and solar installs.
- Worn underlayment that can be replaced by lifting the tile, laying new underlayment and relaying the same tile.
- Clogged valleys and gutters under the mature trees that shade many hillside lots.
- Steep driveways and slopes that make access and material staging part of the plan.

Parts of the Puente-Chino Hills appear on CAL FIRE's map as Very High Fire Hazard Severity Zones. Homes inside those zones need a Class A roof assembly and vents whose mesh openings fall between 1/16 and 1/8 inch on a reroof, so every quote starts with a fire-map check of the address.
Roofing services for Rowland Heights, CA properties
Tile Underlayment Replacement
Concrete tile on 1970s-2000s hillside tracts often outlives its underlayment, which can be replaced while reusing the tile, so many owners avoid buying a whole new roof.
Tile Roof Repair
Cracked and slipped tiles from wind, foot traffic and old dish or solar mounts let water reach aging felt on these hillside roofs, most often at valleys and hips.
Skylights
Original acrylic domes on 1980s and 1990s two-story Rowland Heights homes yellow, crack and leak at the curb, and a new unit means relaying tile around the opening.
Fire-Resistant Class A Roofing
Parts of the Puente-Chino Hills are mapped Very High fire zones, which set Class A and ember-vent rules on a reroof.
Flat Roofing
Shopping plazas along Colima Road and Gale Avenue, plus patio covers behind hillside homes, run on low-slope roofs where blocked drains and tired seams cause leaks.
Apartment & HOA Roofing
Townhome and condo associations in Rowland Heights manage shared tile roofs, and their boards need phased schedules, matching tile profiles and written scopes for architectural review.
Rain Gutters
Mature pines and oaks on hillside lots drop needles into valleys and gutters, and overflow on steep driveways and retaining walls needs downspouts sized to carry it away.
What happens when we come out to a Rowland Heights home?
Visits are same-day or next-day when crews are free, with the arrival window given up front. On tile roofs we walk only where tile can bear weight, lift sample tiles to see the underlayment, and photograph the valleys, flashing and any broken pieces.
The written quote separates each line: tile repair or lift-and-relay, any new tile needed to replace broken pieces, deck repairs, and the county permit. If the existing tile is no longer made, we say so and show you the closest matches.

Schabarum Park ridgelines, Pathfinder Road and Gale Avenue
Rowland Heights covers about 13 square miles between Hacienda Heights, Diamond Bar, Brea, La Habra Heights and the City of Industry, and it touches the Orange County line. The 2020 census counted 15,484 housing units, 61.9% owner-occupied. Once part of John Rowland's share of Rancho La Puente and later orange groves, the area grew sharply in the 1990s as the Pomona Freeway carried development east.
Pathfinder Road and Colima Road climb toward the ridges around Peter F. Schabarum Regional Park, where lots back onto open grass hills. Those homes take the most wind and ember exposure, so we check ridge tiles and vents there first. Nogales Street and Fullerton Road lead down to the commercial strips on Gale Avenue.

Roofing and skylight work most requested here
On houses, new underlayment beneath existing tile and leak repair are the most frequent jobs. Flat-roof repairs and coatings come next, on the commercial plazas along Colima Road and on patio covers behind hillside homes. Skylights are a steady request too: many two-story homes from the 1980s and 1990s have original domed skylights that have yellowed, cracked or started to leak at the curb.

County permits and our coverage around Colima Road
With no city government, Rowland Heights gets roof permits from the county and sends its own inspector. When a permit is needed, we file it and book that inspection. Homes in some tracts also answer to an HOA, so ask whether yours needs architectural approval for a tile color change.
Nearby, we cover South San Jose Hills, Diamond Bar, La Habra Heights, La Habra and Brea. Our home base page on roofing in Rosemead explains how we work. Call (725) 745-8803 to book a visit.

Roofing questions from Rowland Heights
Does my Rowland Heights tile roof need replacing, or just new underlayment?
Often just the underlayment. Concrete tile usually outlasts the felt beneath it. Where most tiles are sound, they come up, the underlayment and flashing are replaced, and the same tile is relaid with matching pieces for any breaks. We show you photos of the underlayment so you can see why.
Who handles roof permits in Rowland Heights?
LA County Public Works Building & Safety, because Rowland Heights has no city government. Permit filing and the county inspection are handled by us when the work requires them. If your home sits in a mapped fire hazard zone, the county will expect a Class A assembly and compliant vents.
Can you replace an old domed skylight on a tile roof?
Yes. We remove the tile around the skylight, take out the old dome and curb flashing, install the new unit with fresh flashing and underlayment, and relay the tile around it. Swapping to a flat-glass or venting model is often possible within the same opening.
Do cool-roof rules apply if I reroof with tile?
Often not. Title 24 cool-roof rules can apply when 50% or more of a roof is replaced, but roofs weighing 25 pounds per square foot or more, which covers most concrete and clay tile, fall under an exception. Shingle reroofs are a different story. We confirm the requirement with the county before ordering material.
