CertainTeed Roofing in South El Monte, CA | Hollywood Roofing Co
We provide independent CertainTeed roofing service across South El Monte, from patching a blown shingle tab to tearing off a sun-baked reroof. What makes our CertainTeed work here different is that we know how Landmark shingles fail on the older tract homes that dominate this city, and we check the drainage details near the Whittier Narrows before we ever hand you a number. Call (833) 589-7971 for a straight answer and a free estimate.
Why South El Monte Residents Choose Us for CertainTeed Service
CertainTeed is one of seven roofing material brands we work with every week, which means our recommendation comes down to what your home actually needs, not what a supplier wants us to move. We are not manufacturer-affiliated or authorized by CertainTeed, and we are clear about that. What we are is a crew that has pulled apart enough CertainTeed assemblies on 1950s-to-70s tract homes to know exactly where they hold up and where they let go.
Roland Vega, our owner, learned roofing at Los Angeles Trade-Technical College and has spent the better part of three decades working roofs across Hollywood and the surrounding communities. That background shapes how we approach every CertainTeed job in South El Monte and our El Monte CertainTeed service. We use CertainTeed-manufactured shingles, ridge caps, starter, and underlayment so the assembly stays compatible, and we are not shy about telling you when a repair will outlast a reroof, or the other way around.
Whether your roof needs a patch or a full replacement, we handle it start to finish. From the first inspection to the final nail.

Common CertainTeed Roofing Problems We Solve in South El Monte
- UV-baked, curled shingle tabs on west and south-facing planes. South El Monte’s dry summers bake CertainTeed asphalt faster than inland roofers expect. We regularly see Landmark shingles on 1960s tract homes that have curled and cracked along the sun-facing exposures while the shaded sides still look new. Repair means replacing those tabs before wind-driven rain gets under them.
- Leaks at flashings and valleys from disintegrated original felt. When a home still carries original felt under second-generation shingles, the felt has often turned to dust. The shingle field looks fine until the winter rains come. Then leaks show at valley metal and pipe boot flashings. In South El Monte, the rainy season exposes this every year on older low-slope planes.
- Loose shingle tabs and ridge caps after Santa Ana wind events. Shallow-pitch roofs with short eave overhangs get their bottom course lifted by wind gusts off the San Gabriel foothills. Once the starter strip is exposed, wind-driven rain wicks under. We reset and seal the lifted courses before they become a full tear-off.
- Dried-out underlayment at flat-to-steep transitions. Older South El Monte homes often have a low-slope patio cover or rear addition tied into a CertainTeed shingle plane. That transition is where original felt dries out and flashing lifts, and where we find leaks long before the shingle field shows any damage.
- Flat and low-slope commercial roof damage near the Narrows. South El Monte mixes residential tracts with industrial and auto-body buildings along the 60 Freeway and Whittier Narrows corridors. Flat roof membranes there crack, pond, and pull at the edges. We patch and repair those flat roofs with the same attention to drainage that we give a shingle reroof.
CertainTeed Service in South El Monte: What Local Conditions Mean for Your Roof
South El Monte sits low in the Whittier Narrows geography, and that single fact changes how we approach CertainTeed roofing here more than any other local condition, including our CertainTeed in North El Monte. During heavy winter storms, the flat and low-slope roofs near the Narrows get tested by localized flooding in a way that homes a few miles uphill never experience. Water ponds, scuppers clog, and every flashing detail gets a pressure test.
What does that mean for a CertainTeed shingle homeowner? It means we inspect the scuppers, drains, and flat-to-shingle tie-ins on a mixed residential and industrial block before we ever price a shingle repair. On a 1960s single-story tract house off Santa Anita Avenue near the Narrows, our crew opened a Landmark architectural shingle roof that had leaked at the rear addition for two seasons. The shingles themselves were mostly intact. The original felt where the low-slope patio cover tied into the shingle plane had dried out and the flashing was lifting. We stripped that transition, replaced the underlayment with CertainTeed DiamondDeck, reset the flashing, and re-laid matching Landmark shingles. The leak has not returned.
A roof doesn’t ask for much, just that you pay attention before it has to ask loudly.
CertainTeed Models & Products We Service in South El Monte
We work on the full range of CertainTeed lines found on South El Monte roofs. Landmark architectural shingles cover the most ground here, including Landmark 30 and Landmark Pro on newer reroofs. Presidential Shake and Presidential TL show up on homes where owners wanted a heavier shadow line. We also service older Xtar, Patriot, and NorthGate lines still present on original tract roofs, as well as DiamondDeck and RoofRunner underlayments used under low-slope and shingle assemblies, and we offer CertainTeed in Temple City.
Our parts approach is straightforward: we use CertainTeed-manufactured shingles, matching ridge caps, starter strips, and underlayment so the warranty and the material chemistry stay consistent. Where the OEM part is not the weak link, we substitute quality aftermarket flashing and fasteners that are honestly better than what left the factory. We stock common CertainTeed colors and accessories locally for fast turnaround in South El Monte. For full CertainTeed sales and service detail, see our CertainTeed sales & service page.

AfterCertainTeed Service Pricing in South El Monte
CertainTeed service pricing in South El Monte ranges from about $350 to $1,300 for a targeted repair, like replacing blown shingle tabs on a windward plane or re-flashing a leaking valley, and from $8,500 to $25,000+ for a full reroof on a typical 1950s-to-70s tract home. The spread depends on roof size, pitch, tear-off layers, whether the deck needs work, and which CertainTeed shingle line you choose. A Landmark architectural reroof lands differently than a Presidential Shake upgrade.

FAQs – CertainTeed Roofing in South El Monte
The leak is almost always at the flat-to-steep transition where the addition ties into the original shingle plane. On older South El Monte homes, the original felt at that tie-in dries out and the flashing lifts, so water gets in at the seam while the shingle field stays dry. We strip that transition, replace the underlayment with DiamondDeck, reset the flashing, and re-lay matching shingles. Call (833) 589-7971 and we’ll find the real entry point before you spend money on the wrong repair.
Yes. South El Monte’s low-lying geography means flat and low-slope roofs near the Narrows pond water and stress their drainage far harder than roofs a few miles uphill. Scuppers clog, membrane edges lift, and tie-ins get tested during every heavy storm. We inspect drains and flashings before pricing any repair near the Narrows. Call (833) 589-7971 for a free estimate that includes the drainage check.
We install Landmark architectural shingles most often, including Landmark 30 and Landmark Pro, because they match the look and performance most older tract homes need. For homeowners who want a heavier shadow line, we install Presidential Shake and Presidential TL. We also service and match older Xtar, Patriot, and NorthGate lines when the job calls for it.
Yes. South El Monte’s mix of residential and industrial buildings means we frequently patch a flat garage or warehouse roof that sits feet from a shingled house. We repair the membrane, reseal edge flashing, and make sure the drainage works before we call it done.
Santa Ana wind events lift shingle tabs and ridge caps on shallow-pitch roofs with short eave overhangs, which is a very common South El Monte configuration. Once the starter strip is exposed, wind-driven rain wicks underneath and the top course start to fail. We reset and seal lifted courses after wind events before they turn into a full tear-off. Call (833) 589-7971 and we’ll tell you if what you’re seeing is wind lift or something deeper.
