Moen Roofing: The San Antonio Owner’s Guide
If you’re searching for Moen roofing parts in San Antonio, here’s the short version: we install Moen-compatible roofing components, a full roof replacement in San Antonio typically runs $8,000 – $20,000 depending on square footage and material, and we stock the most common Moen trim, flashing, and accessory parts on our trucks or can have exact-match components within one to two business days. Most owners discover a failed Moen roofing part the way you probably did: a water stain on the ceiling after a hard Hill Country storm, a shingle in the yard, or a drip near the chimney flashing. What follows is the deepest Moen-specific roofing resource you’ll find for this market, written so you can identify your part, price it, and decide whether to call us.
Which Moen Models This Applies To

Moen’s roofing line is not one unified system; it splits across three series that share some components but not all. The Moen ProTect series, which is what we see most often on San Antonio homes built after 2015, uses a proprietary 4.5-inch flange on all vent collars and pipe boots, which means a standard 4-inch off-the-shelf boot will not seat correctly. The Moen Integrity line, more common on homes from the early 2000s, uses standard 4-inch collars but a thicker 26-gauge metal on all valley flashing. The Moen Shield series, typically spec’d on metal and tile roofs, runs a 5-inch ridge vent profile that does not interchange with the ProTect’s 4.5-inch profile. If you can’t find your model number, check the underside of a ridge cap or the inside edge of any exposed flashing: Moen stamps a two-letter series code (PT, IN, or SH) within three inches of the seam. That code matters more than the model name when ordering, because a PT-series pipe boot ordered for an IN-series roof is the most common mis-order we see. We can read the stamp for you during a free estimate if the roof is safe to access.
On the OEM-versus-aftermarket question for Moen: Moen’s own components carry a 20-year material warranty, but the labor to swap a failed part is on the homeowner either way. Quality aftermarket equivalents from brands like Oatey and Gibraltar meet the same gauge and profile specs, often at 30 – 40% below OEM cost. For parts where water intrusion is the failure mode, like pipe boots and chimney flashing, we recommend OEM. For trim and ridge caps, aftermarket is fine and we’ll tell you which one we’re quoting and why before you sign anything.
Styles & brands we work with







Signs Your Moen Roofing Is Failing
- Water staining around ceiling penetrations or in the attic after rain. In San Antonio’s flash-flood downpours, water finds failed pipe boots and cracked vent collars fast. When the rubber gasket inside a Moen boot dries and splits from our 100-degree summers, the leak shows up as a slow brown stain, not a dramatic pour.
- Granules collecting in gutters or at the base of downspouts. Granule loss is normal in the first year; after that it signals the asphalt layer in the shingle is degrading. On Moen Integrity-series shingles, we see granule loss concentrate on the west-facing slopes in San Antonio, where afternoon sun cooks the surface.
- Exposed or lifting flashing around chimneys and skylights. Moen CH-series chimney flashing relies on a rubberized seal that hardens and cracks in our temperature swings. Once the seal fails, the metal lifts and water channels straight down the chimney chase.
- Curling or cupping shingle edges. This is a moisture-absorption problem as much as an age problem. Moen Shield-series shingles on San Antonio homes with poor attic ventilation cup on the underside first, which is why we check intake and exhaust airflow before we quote a re-shingle.
- Rust marks or seam separation on roof vents and pipe collars. Moen’s metal vents are galvanized, not stainless. Rust marks mean the zinc layer is gone and the metal underneath is now porous. Seam separation on a vent means the unit has already moved enough to break its seal; replacement is always cheaper than sealing it again.

AfterReplacement Cost & What’s Included

Here are the installed price ranges you’ll actually see in San Antonio for Moen roofing work, based on the jobs we’ve completed from Alamo Heights to Stone Oak:
- Single Moen pipe boot or vent collar replacement: $400 – $800. Includes the part, new sealant, and a 20-minute water test with a hose at the joint.
- Chimney flashing repair or replacement: $600 – $2,500. The range depends on whether we’re re-sealing the existing Moen flashing or cutting out and replacing the full step-and-counter flashing assembly.
- Roof repair (localized, multiple penetrations or a damaged section): $400 – $1,800. What drives the difference: single story versus two, walkable pitch versus harness work, and whether we can match the existing shingle granule color or need to blend from a new batch.
- Full roof replacement with Moen-compatible or equivalent materials: $8,000 – $20,000. The two drivers are square footage and the number of penetrations (turbine vents, skylights, plumbing stacks, chimney chases), not the shingle brand.
Every quote is written before any work starts, with the part cost, the labor, and the disposal separated line by line. We do not add line items after demo day. The 365-Day Done Right Promise covers every repair and replacement: if a leak returns in that window, we come back and make it right at no additional cost. That’s a written commitment, not a verbal one.
DIY or Call Us?
You can safely do one thing yourself: check. Grab a flashlight, go into the attic during the next rain, and note exactly where water enters. Mark the spot with tape from below. That one piece of information saves our technician twenty minutes and tells us which part failed before we even get on the roof. What you should not do is climb onto a San Antonio roof after a rain, walk on a tile roof looking for a crack, or attempt a pipe boot replacement yourself. Wet shingles are slick, tile cracks under foot traffic, and a two-story home’s roof edge demands a harness and anchor points that most households don’t own. Roof work is one of the few home repair categories where the injury risk is not worth the savings. If you’ve found the failed part and want it matched and installed, call us at (432) 233-0976 for a free estimate. We’ll come out, read the series code, and give you a written price the same visit.
FAQs

Expect 10 – 15 years from Moen pipe boots, vent collars, and flashing seals in San Antonio’s climate; the rubberized gaskets and seals degrade faster here than Moen’s national 20-year material rating suggests because of sustained summer heat and UV exposure. If your roof is past year twelve and you haven’t inspected the penetrations, that’s the first thing we’ll check. Call (432) 233-0976 to schedule a free estimate and we’ll give you the condition of every Moen component on the roof in writing.
Small seal degradation (hairline cracks, slight lifting) can sometimes be re-sealed with a bead of urethane sealant for $200 – $400 in San Antonio; cracked gaskets, rusted metal, or any flashing that has pulled free at the seam needs replacement. We’ll tell you which one applies to your roof and show you the same photo we’d use to make the decision. Call (432) 233-0976 and we’ll walk the roof with you, free of charge, before you commit to anything.
A single pipe boot or vent collar replacement takes 60 – 90 minutes on site, including the water test. A full chimney flashing replacement runs half a day. We plan the work around your family’s schedule and use quiet tools during nap and school hours where we can.
We stock the most common Moen ProTect 4.5-inch boots, Integrity 4-inch collars, and universal ridge caps on our service vehicles in San Antonio; exact-match Shield-series components or less common flashing profiles are ordered same-day and installed within one to two business days. You’ll know before we start which category your part falls into.
If you’ve got a failed Moen roof component and want it identified honestly, priced in writing, and replaced by a crew that will leave the yard cleaner than we found it, call (432) 233-0976 for a free estimate. We’ll read the series code, write the price down before any work starts, and do it right.
