CertainTeed Roofing in Rowland Heights, CA | Spartan Roof Repair
Spartan Roof Repair provides independent CertainTeed roofing service across Rowland Heights, CA, similar to our CertainTeed repair in South San Jose Hills. We inspect, repair, and replace CertainTeed shingle, tile underlayment, and low-slope systems on homes throughout the 91748 ZIP. The defining job here is not shingle replacement. It’s lifting sound tile off a dead underlayment and re-laying it over new CertainTeed synthetic underlayment before the next winter storm finds the deck. Call (855) 382-3237 for a free estimate.
We’re a roofing-only contractor, not a generalist with a truck and a website. CertainTeed systems behave differently on hillside tile roofs than they do on flat valley tracts, and we speak that language fluently. Our team works CertainTeed sales & service calls across the San Gabriel Valley every week. If you’re in Rowland Heights and your tile roof leaks while the tile itself looks brand new, you’re in the right place.
Why Rowland Heights Residents Choose Us for CertainTeed Service
Seven roofing brands sit on our material shelf: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters here because Rowland Heights has a lot of concrete and clay tile roofs that don’t need a brand-new roof, unlike homes needing CertainTeed repair in Walnut. They need a contractor who will tell them the truth about the underlayment underneath, not upsell a full tear-off because the tile is 40 years old and looks tired from the street.
Brent Calloway, our owner, has spent over two decades working roofs across Southern California hillside communities. He grew up a few blocks from TeWinkle Park in Costa Mesa and learned roofing fundamentals at Orange Coast College’s construction technology program, where instructors didn’t tolerate shortcuts. That background matters when you’re deciding whether to re-lay 800 square feet of concrete tile or tear it all off. As Brent puts it: “Your roof doesn’t need a speech. It needs a fix.”
We inspect it, we repair it, we replace it. That’s the whole scope. No hand-offs to a subcontractor, no second opinion from a different company when the repair turns into a replacement halfway through.

Common CertainTeed Roofing Problems We Solve in Rowland Heights
- Baked-out underlayment under intact tile: South- and west-facing slopes in Rowland Heights take direct San Gabriel Valley sun for 15-plus years. The felt or older synthetic underlayment cooks to a brittle, chalky layer while the tile on top still looks fine. The first real rain sends water straight to the deck. We lift the tile, remove the dead underlayment, install CertainTeed RoofRunner or DiamondDeck synthetic underlayment, and re-lay the same tile.
- Presidential Shake granule loss and seal failure: CertainTeed Presidential Shake and Presidential Select shingles on hillside custom homes get hammered by afternoon UV on exposed slopes. Granules shed, the sealant strip breaks down, and Santa Ana winds lift the shingles. We see this most often on homes converted from wood-shake where the deck wasn’t re-sheeted properly.
- Valley and dormer flashing failure: Rowland Heights hillside homes have complex rooflines with dormers, varied elevations, and tight valleys. Flashing metal corrodes or lifts over time, and wind-driven rain from those intense winter storms backs up under the tile edges. Water follows the flashing, not the tile.
- Flintlastic SA low-slope membrane breakdown: Many Rowland Heights homes have low-slope sections over garages and additions. CertainTeed Flintlastic SA self-adhered modified bitumen handles these spots well, but after years of thermal cycling between 100-degree summer days and 45-degree winter nights, seams split and blisters form.
- Deck rot hidden under wood-shake conversions: Some hillside lots still have original wood-shake sections. When we replace those with CertainTeed Presidential Shake or Landmark shingles, we often find deck rot where old shake nails missed rafters. It’s a house-by-house condition, not a guess.
CertainTeed Service in Rowland Heights: What Local Conditions Mean for Your Roof
Here’s the thing about Rowland Heights, not CertainTeed service in Valinda, that a generic roofing page won’t tell you. On hillside and canyon-edge streets, tile roofs that look pristine from the curb often hide underlayment that’s been baked to a brittle, chalky layer. The tile itself shows no wear because concrete and clay tile last 50, 60, sometimes 70 years. The 30-year-old felt underneath does not. The first winter storm sends water straight through that dead underlayment, and homeowners are genuinely shocked because the tile on top looks perfectly fine.
This is the defining roofing condition in this ZIP, not shingle replacement. A few years back, our crew worked a 1970s Mediterranean-style home on a hillside street off Fullerton Road. The owner called because ceiling stains appeared only during winter storms. The concrete tile showed zero wear. But when we lifted the west-facing slope, the original felt underlayment crumbled to powder in our hands. We replaced it with CertainTeed RoofRunner synthetic underlayment and new valley and step flashing, then re-laid the same tile. No ceiling leak the following rainy season. That’s the Rowland Heights repair pattern more than any other.
CertainTeed Models & Products We Service in Rowland Heights
We work on the full CertainTeed product range that shows up on Rowland Heights homes. CertainTeed Presidential Shake and Presidential Select shingles on hillside custom homes. Landmark architectural shingles on 1970s and 80s tract homes that replaced original shingle roofs. Flintlastic SA self-adhered modified bitumen on low-slope garage and addition sections. RoofRunner and DiamondDeck synthetic underlayment under tile re-roofs. Plus the accessory flashings, ridge caps, and valley metal that tie those systems together.
On parts, we take a straight approach. We install genuine CertainTeed underlayments, flashings, and shingles where the system calls for them. Where an OEM part adds nothing but cost to a repair, we use quality matching components. On tile roofs, we repair or replace only the failed underlayment and flashing when the tile itself is sound. A full tear-off gets quoted only when the deck or tile actually warrants it. We’re an independent contractor, not manufacturer-affiliated or authorized. That independence is what lets us quote what the roof needs, not what a manufacturer program rewards.

FAQs – CertainTeed Roofing in Rowland Heights
Because the underlayment under the tile has failed, not the tile itself. In Rowland Heights, south- and west-facing tile slopes bake the felt or older synthetic underlayment until it’s brittle and chalky. Water goes straight through to the deck on the first heavy storm. The tile looks fine because tile outlasts its underlayment by decades. Call (855) 382-3237 and we’ll lift a section, show you what’s underneath, and quote the fix.
Yes, in most cases. We lift the concrete or clay tile, remove the failed underlayment, install CertainTeed RoofRunner or DiamondDeck synthetic underlayment with new flashings, then re-lay the same tile. This is the most common job we do in Rowland Heights. The tile stays if it’s sound. A full tear-off only gets quoted when the deck or tile warrants it.
It can be, but the installation details matter more than the product name. Presidential Shake shingles are heavy and thick, which helps on wind-exposed hillside slopes. But the original deck has to be solid, and the sealant strips need proper sun exposure to bond. We’ve seen failures where old wood-shake decks weren’t re-sheeted properly. If you’re considering it, call (855) 382-3237 for a deck inspection before anyone orders materials.
With CertainTeed Flintlastic SA self-adhered modified bitumen. Many Rowland Heights homes have low-slope garage and addition sections that shingles don’t handle well. Flintlastic SA works because it self-adheres to the deck and flexes with thermal cycling. We inspect the seams and blisters first, then quote only what needs replacing. Estimates are free at (855) 382-3237.
Flashing failure, almost always. Valley metal and dormer step flashing corrode or lift over time, especially on hillside rooflines where wind-driven rain pushes water up under tile edges. The water follows the flashing path, not the tile. We replace the flashing, re-bed the tile, and the leak stops. Call (855) 382-3237 for an exact quote.
