CWS Roofing: The San Antonio Owner’s Guide
If you have a CWS roof and something is failing, we can match the exact part, price it in writing before any work starts, and handle the install. A typical CWS roof repair in San Antonio runs $400 to $1,800 installed, and if a full replacement is the right call, we’ll walk you through that range too. Most owners discover a problem the same way: a stain on the ceiling after a hard Hill Country storm, missing granules in the gutter, or a shingle that lifted at the ridge line and never settled back down.
Elmstead Remodeling San Antonio is an independent service provider. We are not affiliated with CWS, and we don’t pretend to be. What we are is a team that has worked on CWS roofing systems across San Antonio, from Alamo Heights to Stone Oak to older homes near King William, where original roof lines demand patience and a careful hand.
Which CWS Models This Applies To

CWS roofing systems are most common throughout Texas as architectural asphalt shingle installations, and the parts we see fail most often are consistent across the product line: ridge caps, hip-and-ridge shingles, flashing, pipe boots, and valley metal. If you’re trying to identify your CWS product, start with the shingle itself. CWS-branded shingles carry the manufacturer stamp on the back of the bundle wrapper, not on the exposed face, which trips up a lot of homeowners digging through a garage full of leftover material.
The compatibility gotcha in San Antonio is heat. A CWS architectural shingle installed ten or twelve years ago has been through repeated 100-degree summers, and the adhesive strip that seals the shingle to the row below it is often the first thing to give out. We match replacement shingles by measurement, not just by brand name. Most CWS architectural shingles run 13 1/4 inches wide by 39 3/8 inches long with a 5 5/8-inch exposure when installed. An OEM CWS shingle is the cleanest match, but there are quality aftermarket architectural shingles in the same weight class and color range that sit flush and look right without costing you an OEM premium. We’ll show you both options on paper before you commit to either.

Signs Your CWS Roofing Is Failing
- Ceiling stains that appear after a hard rain. This usually means water is getting past the shingle layer, not just staining it. On CWS systems in San Antonio, we most often trace it to failed pipe boot flashing around plumbing vents or a nail that backed out and let water follow it down.
- Granules collecting in gutters or at downspout elbows. Some granule loss is normal. A consistent stream of granules every time it rains means the shingle’s protective surface is wearing through, and the fiberglass mat underneath is about to be standing alone under the Texas sun.
- Shingles lifting at the edges or corners. The adhesive strips on CWS architectural shingles can soften and fail after years of San Antonio heat cycles. Once a shingle lifts, wind gets under it, and one lifted shingle becomes three before the next storm.
- Dark streaks or moss at the north-facing slope. Shaded areas under live oaks stay damp longer, and that moisture works into the shingle surface. On CWS roofs around older San Antonio neighborhoods with mature tree canopy, this is one of the most common failure points we see.
- Ridge cap shingles cracked or missing at the peak. The ridge cap takes the brunt of every wind gust. If you can see exposed nails or a gap at the ridge line from the street, you’ve already lost a layer of protection.

AfterReplacement Cost & What’s Included

For a targeted CWS roof repair in San Antonio, plan on $400 to $1,800 installed. The range hinges on what failed and how much of it. A single pipe boot replacement with new flashing sits at the low end. Replacing twenty or thirty lifted shingles across multiple slopes, re-bedding ridge caps, or repairing valley metal lands higher. If a full CWS roof replacement is needed, the installed range in San Antonio is $8,000 to $20,000 depending on roof size, pitch, and the number of layers being removed.
Every price we give you is written down before any work starts. That’s not a courtesy, it’s how Graham Stein has run every scope of work since he started phrasing things this way: write it down, price it once, do it right. The written price includes the parts, the labor, the clean-up, and a photo of the finished work before the crew leaves. No line items added after the first shingle comes off.
DIY or Call Us?
Roof work on a CWS system follows one rule: if you can inspect it from the ground or a ladder without stepping onto the roof surface, go ahead. You can check gutters for granules, look for lifted shingles at the eaves, and note where the ridge line looks uneven. What you should not do is walk a San Antonio roof in August to “take a quick look.” Hot shingles tear underfoot, the granule surface gets scuffed, and a fall from even a single-story roof changes a family’s calendar in ways no repair ever should.
If a pipe boot has failed or flashing has pulled away, the fix requires removing shingles, re-setting the flashing, and sealing it correctly. That’s roofers’ work. Call us at (432) 233-0976 and we’ll come out, look at what’s actually happening, and give you a written price for the fix.
FAQs

A CWS architectural shingle roof in San Antonio typically holds up for 15 to 20 years, but the Texas heat and UV exposure mean the top third of that range usually requires consistent attention to ridge caps, flashing, and ventilation. If your roof is past year 12 and you’re seeing repeated small failures, a repair might buy time but a replacement conversation is worth having. Call (432) 233-0976 and we’ll give you an honest read on where your roof stands.
A single failed shingle or a section of damaged ridge cap can absolutely be repaired without replacing the roof, as long as the underlying decking is still sound. What matters is catching it before water reaches the sheathing. We repair CWS roofs all over San Antonio, and we’ll tell you plainly if a repair is a band-aid or a real fix. Estimates are free at (432) 233-0976.
Most CWS roof repairs we do in San Antonio are finished in a single visit, usually within a few hours once materials are on site. If the repair involves multiple slopes or a re-flashing at a chimney, plan on a full day. We’ll give you a clear timeline in writing before we start, and we’ll call you if anything on the roof tells a different story once we’re up there.
We keep common CWS-compatible components in inventory: ridge caps, pipe boots, flashing, sealants, and architectural shingles in the most common San Antonio color range. Oddball colors or older CWS lines may need a special order, and we’ll tell you that up front, with the lead time and the price difference, before you decide anything.
If your CWS roof is failing, start with one call. We’ll come out, look carefully, and put a written price in your hands before any work begins. Call Elmstead Remodeling San Antonio at (432) 233-0976 to schedule your free estimate.
