AfterLeak Repair in Dallas, TX
A roof leak in Dallas is rarely a single problem. The water that drips onto your hallway ceiling may have entered the roof fifteen feet away, traveled along a rafter, and pooled at a low point before finding a seam to drip through. That’s why leak repair is more detective work than patching. You need a roofer who can trace the actual entry point, fix what failed, and verify the fix before the next storm. That’s what our team at Mercer Roofing Co Dallas does every day with our Roof Repair services.
We repair leaks on shingle roofs, flat roofs, around skylights, chimneys, vents, and wall intersections. Whether it’s a missing shingle, deteriorated flashing, or a nail pop that’s letting water in, we find it, fix it, and put the guarantee in writing before we leave. If you’re seeing water where it shouldn’t be, call us at (432) 302-5605 and we’ll send someone who arrives with a name, a face, and a photo ID you already saw.

When You Need Leak Repair
Some leaks announce themselves loudly. Others hide for months before the first stain appears. Here’s what Dallas homeowners typically see when a roof is letting water in:
- Water stains on ceilings or upper walls. Brown or copper-colored rings, especially after a hard rain, usually mean water is pooling above and wicking through drywall. The stain location often isn’t directly under the roof leak.
- Damp attic insulation or rafters. If you can safely access your attic, look for darkened wood, wet insulation, or a musty smell. In Dallas summer heat, moisture in an attic turns to humidity fast, which can warp decking and encourage mold.
- Missing, cracked, or curled shingles. Hail, high winds, and our temperature swings from 100-degree summers to freezing winter nights take a toll. A missing shingle is an open door for the next downpour.
- Dripping or water marks around chimneys, skylights, or vent pipes. These penetrations rely on flashing to stay watertight. Flashing fails before shingles do, especially the metal-to-shingle transition points that expand and contract with Dallas heat.
- Granules in gutters or at downspout bases. Shingle granules protect the asphalt layer from UV. When they start washing off, the shingle is aging out and losing its water-shedding surface.
- Daylight visible through the roof boards. From inside the attic, if you can see pinpoints of light through the decking, water can absolutely get through the same openings.
Our Leak Repair Process
We follow a set process for every leak repair, because fixing only the visible damage leaves you one storm away from the same problem. Here’s what happens when you call:
- You talk to a live person, not a voicemail. Our phones are answered by a real human being 24/7. You’ll describe what you’re seeing, and we’ll schedule a technician visit at a time that works for you.
- You get a name and photo before the doorbell rings. Every Mercer technician is background-checked and identity-verified under the Threshold Verified standard. We send you the technician’s name and photo ahead of arrival. When they knock, they’ll be in a clean, marked uniform and present a photo ID badge. You’ll know exactly who’s at your door before you open it.
- We inspect the attic, decking, and roofing surface. The technician starts inside where water shows up, then moves to the attic to trace the path, then climbs the roof to find the source. This inside-to-outside approach is how we catch leaks that start at one point and drip at another.
- You get a written price before any work starts. Once we know what’s wrong, we write down the repair scope and the price. You approve it before a single shingle is lifted. No surprises on the invoice, ever.
- We repair the source, not just the symptom. Depending on the diagnosis, that might mean replacing damaged shingles, resealing flashing, repairing pipe collars, fixing nail pops, or replacing a section of decking. We use manufacturer-recognized shingle brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko to match your roof.
- We test and verify the fix. Before we pack up, we confirm the entry point is sealed, the repair area is water-shedding properly, and surrounding materials are sound. Then we hand you a written guarantee that covers the repair for 365 days.
Leak Repair Pricing in Dallas
Every roof leak is different, so pricing depends on the diagnosis. That said, here’s what Dallas homeowners typically pay for common leak repairs, based on what we see across the metro:
- Minor shingle replacement (1-5 shingles): $175-$350. Small, localized damage from wind or impact, usually a quick fix when the decking underneath is sound.
- Flashing repair or reseal around a chimney, skylight, or vent: $300-$700. Most leak sources are flashing, not shingles. This includes removing old sealant, refitting or replacing the flashing, and resealing the transition.
- Pipe collar / vent boot replacement: $225-$450. Rubber boots crack in Dallas heat and UV, often within 8-12 years. Replacing the boot and sealing the base stops the drip.
- Nail pop sealing: $150-$300. Nails backing out of the decking create small holes that let water in during heavy storms. We reseat or replace the nail and seal the entry point.
- Decking replacement (localized section): $500-$1,100 plus shingle work. When water has been entering for months, the plywood or OSB decking can rot and needs replacement before new shingles go on.
- Flat roof leak on a Dallas porch or carport: $300-$800. Flat roof membranes fail at seams and terminations, often repairable without a full re-roof.
What actually moves the price is the scope of damaged material, the roof’s pitch (steeper roofs take longer), and whether decking or underlayment replacement is required. Some Dallas homes built before updated city code may have only one layer of underlayment, which we’ll flag if we think your leak will recur without addressing it. You’ll know the exact price before we start. Call (432) 302-5605 for a free estimate, and we’ll walk you through what we find.
FAQs – Leak Repair
How much does a roof leak repair cost in Dallas?
Most Dallas roof leak repairs run between $175 and $1,100, depending on the source and extent of damage. A few missing shingles or a nail pop is on the low end. Deteriorated flashing around a chimney or skylight usually runs $300-$700. If water has been entering long enough to rot the decking, you’re looking at $500-$1,100 plus shingle work. Call (432) 302-5605 for an exact quote. Estimates are free, and everything is in writing before any work begins.
Can you fix a roof leak the same day?
In most cases, yes. Our technicians carry the most common repair materials, including shingle varieties that match Dallas’s most popular roofing brands like IKO, Atlas, and Tamko, so a straightforward leak can be addressed on the first visit. If your leak is severe or the decking needs replacement that requires material delivery, we’ll schedule the repair for the next available slot and secure a temporary tarp if needed. Call us. A live person answers 24/7, and we’ll tell you honestly whether same-day is realistic for your situation.
Is it cheaper to repair a leak or replace the roof?
Repairing a leak is almost always cheaper than replacing the roof, and it’s the right call if the roof structure is sound and the damage is localized. A repair costs a few hundred dollars in most cases, while a full replacement in Dallas runs $8,000-$16,000 or more depending on roof size and material. Where replacement makes sense is when you have multiple leaks, widespread shingle failure, or decking rot across large areas. Our team will tell you if a repair is a temporary fix or a lasting solution, and we’ll never sell you a full replacement when a repair will do the job.
How do I know if my roof leak is actually a plumbing leak?
Water on a ceiling below a bathroom or near a plumbing vent can come from either the roof or a supply/drain line. Here’s a simple check: if the water appears only when it rains, it’s almost certainly the roof. If it appears regardless of weather, check your plumbing. We trace water stains from the attic side to confirm the path. If we find the roofline and decking are dry and the water originates from a pipe, we’ll tell you plainly, so you can call a plumber rather than pay for roof work you don’t need.
Does the 365-Day Done Right Promise apply to leak repairs?
Yes. Every leak repair we perform in Dallas is covered by a written guarantee for 365 days. If the same repair fails within a year, we send someone back at no charge to make it right. It’s included with the job, not an upsell. We give you the guarantee in writing before we leave, along with the written price and repair description, so there’s no ambiguity about what was fixed and what’s covered.
