CertainTeed Roofing in Paramount, CA | Van Nuys Roofing Co
We provide independent CertainTeed roofing service across Paramount, from Landmark architectural fields to Flintlastic low-slope membranes on the commercial corridors. What sets our CertainTeed work apart here is that we know the #1 variable isn’t the shingle: it’s the 1950s carport or patio cover sharing the same roof plane as the house. Call (866) 321-6172 to have a real roofer look at yours.
Van Nuys Roofing Co is an independent CertainTeed service provider. We are not authorized, sponsored, or endorsed by CertainTeed. We stock and install their products because they hold up in Paramount’s sun, and because we’d rather give you the material that fits your roof than steer you toward whatever’s on the truck.
Why Paramount Residents Choose Us for CertainTeed Service
Seven leading brands, one crew that knows them all. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, Boral – if it goes on a roof, we’ve torn it off, patched it, or installed it. That breadth matters in Paramount, where one block of 1950s tract homes can sit three doors down from a flat-roof industrial building that needs a completely different CertainTeed service in Lynwood system. We inspect first, recommend second, and we won’t push a full replacement when the roof has five honest years left.
Rick Dominguez learned the trade at Los Angeles Valley College’s construction technology program and has spent the better part of two decades on rooftops before starting Van Nuys Roofing Co. He’s the one who set the rule we work by: if it doesn’t need replacing, we’re not going to tell you it does. We bring that same straight talk to every CertainTeed roof we touch in Paramount.
We’re a full-cycle shop – roof repair, roof replacement, and roof inspection all handled in-house. No referrals, no subcontracted crews you’ve never met. Your roof, your material choice, and our job is to make sure it’s installed the way CertainTeed’s specs actually require.

Common CertainTeed Roofing Problems We Solve in Paramount
- Baked-brittle XT 25 and XT 30 three-tab fields. Paramount’s intense sun hits unshaded south and west slopes hard. Original 1950s and 60s three-tab shingles lose granules fast and go brittle, so they snap rather than tear cleanly during removal. This slows the job and means decking gets inspected more carefully after tear-off.
- Landmark shingles failing at carport tie-ins. When a Landmark field runs across a low-slope carport section it was never rated for, the transition fails first. Water gets in at the slope change, and by the time you see a ceiling stain, the decking beneath is already softening. Paramount has these tie-ins on block after block.
- Flintlastic seam cracks on corridor roofs. Along Alondra Boulevard and the 710 freeway edges, constant truck vibration and diesel soot work on modified-bitumen seams. Cracks stay hidden until winter rain finds them. We see the same soot film on almost every commercial roof in that zone.
- Rusted vent boots and valley metal on stucco tract homes. On these 60-year-old roofs, the metal fails well before the shingle mat. A rusted vent boot or corroded drip edge turns a tiny leak into eave deck rot. Shingles look fine, decking doesn’t.
- Unpermitted carport additions with no step flashing. The original carport often meets the house with a nail-and-tar seam. No step flashing, no kick-out. Re-roofing means correcting that transition, or the new CertainTeed shingles leak the same way the old ones did.
CertainTeed Service in Paramount: What Local Conditions Mean for Your Roof
On many Paramount streets, the original 1950s carports and patio covers share one continuous roof plane with the house, and those additions were commonly built unpermitted and flashed incorrectly. So a simple CertainTeed re-roof here routinely turns into a structural and flashing correction, not a shingle swap. We’ve walked enough of these roofs to know what we’ll find before we even set the ladder: a low-slope section that never should have had architectural shingles, a transition seam held together with tar and hope, and decking that’s been drinking for decades. The shingle brand matters less than what’s underneath it, so we price the decking and flashing work honestly instead of shingling over a problem that’ll leak again in two Paramount winters.
CertainTeed Models & Products We Service in Paramount
We install and repair the full CertainTeed line that makes sense for southern California: Landmark architectural shingles for most pitched tract homes, XT 25 and XT 30 three-tab where a 1:1 match to an existing adjacent roof is still possible, Presidential Shake for homeowners who want that heavier luxury profile, and Flintlastic modified-bitumen membrane for low-slope residential and commercial roofs across the Gateway Cities, including CertainTeed service in Bellflower.
We use CertainTeed-branded shingles and Flintlastic membrane where they belong. But flashings, vent boots, and underlayment get spec’d on merit. On Paramount’s 60-plus-year-old decks, a quality synthetic underlayment and new metal usually matter more than the brand on the bundle.

AfterCertainTeed Service Pricing in Paramount
Roof replacement in Paramount typically runs $8,500 to $22,000 for a Landmark architectural field with tear-off, decking inspection, new flashing, and proper tie-in correction at any attached carport. Flat roof or Flintlastic membrane work on a detached structure starts around $4,500. Roof repair work varies by damage: vent boot replacement $400 to $800, step flashing repair $500 to $1,200, and localized decking replacement $800 to $1,500. Structural corrections at unpermitted carport tie-ins land in the $1,500 to $3,000 range depending on how much framing needs attention.
What drives the final number in Paramount: the condition of the original decking, whether carport and patio cover tie-ins need structural correction, and building permit requirements. Our free estimate includes a written line-item breakdown so you know exactly where the money goes. Call (866) 321-6172 and we’ll get on the roof and give you real numbers.

FAQs – CertainTeed Roofing in Paramount
In most cases, no. Those 1950s carport tie-ins were commonly built unpermitted, with nail-and-tar seams and no step flashing. Re-shingling over that transition just hides the problem under new CertainTeed shingles. We tear off, correct the flashing and low-slope transition using Flintlastic membrane, and rebuild the decking if it’s rotted. Call (866) 321-6172 and we’ll inspect your tie-in before you spend a dollar.
That’s Paramount sun and heat cycles doing what they do. Unshaded south and west slopes bake all afternoon, and after 20-plus years, the asphalt mat under the granules gets brittle enough to snap. The north side might still have a few honest years left. A repair-only approach on the bad slope works when the rest of the field is sound, but we’ll tell you straight if a full replacement makes more sense.
Yes. Commercial and industrial roofs near the Alondra Boulevard and 710 freeway corridors deal with heavy truck vibration and diesel soot that homes don’t. Flintlastic seams crack under repeated vibration, and soot masks the cracks until rain finds them. We inspect and repair those low-slope membranes with the same CertainTeed products, including CertainTeed service in Downey, but the failure patterns are completely different from residential work.
Most Paramount homes from the 1950s and 60s need a full tear-off. Building codes typically limit shingle-overs to one existing layer, and many of these roofs have the original 3-tab still in place. Plus, a shingle-over hides decking rot at the eave and fails to correct the carport tie-ins we keep finding. If your decking has been wet, we tear off and start from the sheathing up.
Landmark architectural shingles for pitched tract homes, XT 25 and XT 30 three-tab where a match is required, Presidential Shake for homeowners who want the heavier profile, and Flintlastic modified-bitumen membrane for low-slope residential and commercial roofs. We’re an independent CertainTeed service provider, so we recommend the product line based on the roof’s slope and the budget, not brand loyalty.
