AfterValley Repair in Houston, TX
Roof valley repair in Houston typically runs $350 – $900 for most homes, depending on how much Flashing Repair is needed and whether the plywood decking underneath has rotted. A leaking valley is one of the most common roof failures we see in Houston, because our heavy afternoon downpours dump enormous volumes of water into the narrow channels where two roof slopes meet. If water is getting in around a valley, call our team at (254) 566-3573, and we’ll get someone out to look before the next storm hits.
A valley is the V-shaped channel where two roof planes come together. Most Houston homes have at least one, and many have three or four. When the metal flashing in that channel fails, water stops being directed off the roof and starts working its way under the shingles. Our Roof Repair in Houston service handles valley failures all year long, and we stake our name on getting it right the first time. That’s the Kingswell Way: say the price before the work, show up in the window we gave, put the guarantee in writing, and come back if it fails.
What sets our valley repair work apart is the written guarantee. Every valley repair we do at Tilehurst Roofing Houston comes with a guarantee in writing before the crew leaves the driveway. If that repair fails inside the guarantee period, we return and correct it at no charge under our 365-Day Done Right Promise. No phone tag. No “we’ll see what we can do.” It’s on paper.
When You Need Valley Repair
Valleys take more abuse than almost any other part of a Houston roof. They collect water from two slopes at once, and in a city that gets 50-plus inches of rain a year, that means they fail faster than the surrounding shingles. Here are the signs we see most often:
- Water stains on the ceiling near a gable or an interior corner. Valleys often run directly above bedrooms, hallways, and stairwells. A brown stain that widens after heavy rain is the classic first symptom.
- Visible rust, cracks, or lifting in the metal valley lining. Older homes in Meyerland, Spring Branch, and Timbergrove often still have galvanized steel valleys that corrode slowly in Houston’s humidity. Once the metal pinholes, water follows the holes straight into the attic.
- Granules collecting in gutters below valley lines. Shingle edges along a valley take constant shearing from fast-moving water. If you see heavy granule loss right below a valley, the shingles are wearing out there faster than anywhere else on the roof.
- Shingles lifting or curling at the valley edges. Improperly nailed shingles near a valley will start to lift within a few Houston summers. The shingles should lie tight against the valley metal. If they don’t, water will blow underneath them during wind-driven rain.
- Debris dams in the valley channel. Oak leaves, pine needles, and moss build up in the V and hold water against the roof surface for days after a storm. That standing water eventually finds its way through.
- Drips heard in the attic during or after rain. If you can hear water hitting the attic floor or insulation after a big storm, a valley leak is a strong suspect. It may be running down the valley from a small hole ten or fifteen feet away.
One thing worth knowing if you live in a neighborhood with mature trees: Houston’s live oaks are beautiful, but they shed constantly. Valleys catch that debris worse than any other roof section. If you haven’t looked at your valley channels in a couple of years, they’re probably holding leaves right now. A quick inspection costs nothing, and we’d rather catch a small issue early than tear out wet decking later. Call us at (254) 566-3573 to schedule one.
Our Valley Repair Process
When you call Tilehurst Roofing Houston, a live person answers. Not a voicemail box, not a queued message, not a “we’ll call you back within two business days.” You’ll talk to someone immediately, any hour of the day or night. From there, here’s exactly how a valley repair goes:
- We schedule a visit and show up in the window we give. You’ll know when we’re coming. Our technicians wear uniforms and are background-checked, so when a Tilehurst truck pulls up, you know exactly who is walking onto your property.
- We inspect the valley, the surrounding shingles, and the decking underneath. We remove just enough material to see what’s happening. Sometimes the valley metal itself has failed. Other times the problem is the shingle overlap, or the underlayment beneath the valley has torn, which is a roofing felt that acts as a second layer of water protection.
- We hand you a written price before any work starts. That price includes the materials, the labor, and the disposal. It does not change at the door. If we discover the decking is rotted, we’ll show you the damage, explain the additional cost, and get your approval on paper before we touch it. You’re never surprised at the end.
- We repair the valley, not just patch it. That usually means replacing the metal flashing, or resurfacing the valley with fresh material that matches your existing roof. We explain every trade term in plain language: the flashing is the metal channel that carries the water; the underlayment is the waterproof barrier beneath the shingles; the drip edge is the metal strip that keeps water from curling back under the roof edge. You’ll understand what we’re doing and why.
- We clean up completely. Old shingles, nails, scraps, packaging: it all leaves with us. We sweep the area with a magnetic roller to pick up any stray fasteners from your driveway and lawn. The Kingswell Way says leave the place cleaner than we found it, and that’s non-negotiable.
- We hand you the written guarantee before we leave. Not emailed later. Not mailed “in 7 – 10 business days.” In your hand, on the spot, with the coverage period clearly stated. If the repair fails inside that window, we come back and make it right at no charge.
Valley Repair Pricing in Houston
Here’s what we tell every Houston homeowner before they commit to anything: most of our Roof Repair services run $350 – $900, and valley repairs sit solidly in that same range. The final number depends on a handful of factors we can assess within about twenty minutes on your roof. Here’s a realistic breakdown of what affects the price:
- The valley length. A short valley over a dormer might run 8 – 10 linear feet. A long valley on a two-story colonial can stretch 20 feet or more. More linear feet of metal means more material and more time.
- The decking condition. Decking is the plywood under your shingles. In a home built before the mid-1990s, valley leaks often mean sections of plywood have been soaking for months. If the decking is soft or delaminating, we replace the affected area. That adds cost but prevents a far worse problem later.
- The type of valley flashing. Most Houston homes use aluminum valley metal, which is affordable and resists corrosion well. If your home has an older copper valley and you want to keep the original character, the material cost goes up meaningfully. We’ll quote both options where it applies.
- The shingle material. Standard three-tab shingles are the least expensive to work with. Architectural shingles are slightly more. If your roof uses heavier materials, the valley work has to be matched carefully to preserve the roof’s water channel integrity.
- Whether the valley needs to be entirely rebuilt. Sometimes the shingle overlap on both slopes is too short, or the valley was installed without proper underlayment in the first place. In those cases, a true fix means tearing back a wider section of shingles on both slopes and rebuilding the valley properly. That’s the $800 – $900 end of the range.
We give you the exact number before we start. No “well, it might be more once we get in there.” If we open it up and find more damage, we stop, show you, and get a signed change order before we proceed. That’s the only way we do business.
As for materials, we carry options from GAF, CertainTeed, Owens Corning, and Boral, so we can match your valley repair to what’s already on your roof rather than forcing whatever happens to be in the truck. You’ll get a quick explanation of your options and our recommendation based on your home’s pitch, age, and what the existing shingles need. Want us to come take a look? Estimates are free. Call (254) 566-3573 and we’ll schedule a visit.

FAQs – Valley Repair
How much does valley repair cost in Houston?
Most valley repairs in Houston run between $350 and $900, depending on valley length, decking condition, and the type of flashing and shingles required. A simple aluminum valley replacement with no decking damage often lands around $400 – $550, while a full valley rebuild with rotted plywood removal and new underlayment can reach $800 – $900. For flat sections, we also offer Flat Roof Patch solutions. We give you the exact written price before any work starts, so there are no surprises. Call (254) 566-3573 for a free estimate on your specific roof.
How long does a valley repair take?
A straightforward valley repair usually takes one day, including tear-out, new flashing, shingle replacement, and full cleanup. If the decking has rotted and needs to be replaced, the job may extend into a second day depending on how much plywood has to come out and how large the roof section is. We’ll give you a clear timeline when we do the initial inspection, and we stick to the window we give.
Is a valley leak an emergency?
Yes, a valley leak is an emergency in the sense that it will not get better on its own, and every heavy rain makes the damage worse. Houston gets hard, fast storms that can dump water into an open valley for hours at a time, and a small leak becomes a big one quickly. If you see water coming in around a valley, call (254) 566-3573 right away. We answer live around the clock, and we can get someone to your home quickly.
Can I repair a roof valley myself?
We strongly recommend against it. Valley work requires working on a sloped roof, often near the edge, and the valley is the highest-stress water channel on the entire structure. A mistake in the underlayment or flashing overlap won’t just leak; it will leak directly into your attic and can remain hidden for months. The safety risk is real too. This is one of those repairs where a trained professional is the right call. Our technicians have the experience to do it safely and correctly, and the work is backed by a written guarantee.
