AfterFull Roof Replacement in Dallas, TX
A full roof replacement in Dallas means tearing off the existing roof down to the decking and installing a new roofing system from the deck up. That includes new underlayment, new flashing, new drip edge, and new shingles or roofing material, installed to manufacturer specification. If your roof is past its useful life or has damage that patchwork repairs can’t solve, this is the job that puts the problem to rest. Brennan Roofing Co Dallas handles full roof replacements with a discipline most Dallas roofers don’t offer: a written price before any work starts, uniformed and background-checked technicians on the job, and a one-year written guarantee called the 365-Day Done Right Promise. Call (903) 499-4441 to schedule a free estimate.
We’re not the cheapest roofer in Dallas and we don’t try to be. We compete on something harder to find: a defined standard that is the same on every job, from a small repair to a complete Roof Replacement & Installation in Dallas. If you want to know who’s on your roof and what the job costs before it starts, we’re built for that.
When You Need Full Roof Replacement
Some roofs can be repaired. Some should be replaced. Here’s how to tell the difference in Dallas:
- Age of the roof. Most asphalt shingle roofs in North Texas last 15 to 25 years depending on ventilation, sun exposure, and how well they were installed. If your roof is past that window, a full replacement is usually cheaper in the long run than paying for repeated repairs on a roof that’s already tired.
- Hail damage across multiple slopes. Dallas gets meaningful hail on a regular basis. If hail has hit the majority of your roof and the shingles show bruising or granule loss across several roof faces, spot repairs are a temporary fix. A full replacement is the permanent one.
- Curling, cracking, or missing shingles in clusters. A few missing shingles after a storm can be repaired. If you’re seeing curling or cracking across wide sections, the shingle system itself is failing. The roof is telling you it’s done.
- Leaks in more than one room. One leak often points to a specific flashing or valley issue. Multiple leaks in different rooms usually mean the roof membrane is failing across the whole system, not in one spot. That’s a replacement signal.
- Sagging or soft decking. If you notice a dip or soft spot when you walk the roof or look along the ridge line, the decking underneath is likely moisture-damaged. Full replacement lets us inspect and repair the decking before the new roof goes on. Repairs alone can’t fix decking that’s already gone soft.
- Granules in the gutters. Every roof sheds some granules early on. When you’re seeing a steady stream of granules in the downspouts year after year, the shingles are losing their protective layer and drying out. It’s usually a sign the roof is in its final years.
Our Full Roof Replacement Process
Here’s exactly how a full roof replacement with Brennan Roofing Co Dallas works, in order:
- Written estimate before any work starts. We inspect the roof, take measurements, and put a price on paper. You get the number before you agree to anything. The price does not move at the door, and it does not change after we start unless we find hidden decking damage, which we’ll show you and discuss before touching it.
- Material selection with real options explained. We walk you through your choices in plain language. We install materials from manufacturer lines including GAF, CertainTeed, Owens Corning, and more. If you want an impact-resistant shingle for Dallas hail or a specific color and profile, we’ll show you what it costs and how it performs. No upsell pressure. Just facts.
- Tear-off and decking inspection. We remove the old roof down to the decking. That’s when we see what’s underneath. If decking is rotten or water-damaged, we replace it before the new roof goes on. You don’t want a new roof nailed to a rotted frame.
- New system installed in the right order. Drip edge goes on first, then underlayment, then flashing at every penetration and valley, then the shingles or roofing material, then final sealing and cleanup. Every layer has a job. We don’t skip steps or cut corners to save time.
- Inspection and walkthrough with you. When the job is done, we walk the property with you, show you what we did, and answer questions. We verify that every part of the system is installed to manufacturer spec. You get the written guarantee before we leave.
- Cleanup and magnetic sweep. We clear the job site. We run a magnetic sweep for nails around the perimeter and in the driveway. You shouldn’t find roofing nails in your yard three weeks after we leave.
Full Roof Replacement Pricing in Dallas
A full roof replacement in Dallas typically runs between $9,000 and $22,000 on a standard 1,800 to 2,500 square foot single-family home with asphalt shingles. The main drivers are roof size, pitch, number of stories, material choice, and whether the decking underneath needs repair.
| Cost Factor | Typical Range in Dallas | What It Means |
|---|---|---|
| Asphalt shingle replacement (standard 3-tab or architectural) | $4.00 – $5.50 per sq ft | The most common choice for North Texas homes. Good balance of cost and life span. |
| Upgraded architectural shingles (impact-resistant, Class 4) | $5.50 – $7.50 per sq ft | Higher material cost, but often reduces hail damage claims and can lower insurance premiums. |
| Decking repair or replacement (per 4×8 sheet) | $70 – $100 per sheet | Only applies if the tear-off reveals rot or water damage. We show you before we replace anything. |
| Steep or two-story roof surcharge | 10 – 20% over standard rates | Slower work, more safety equipment, more labor hours. A 6/12 pitch costs less to replace than a 10/12. |
| Chimney, skylight, or vent re-flashing | $200 – $600 per penetration | Flashing is the most common leak point on a roof. Proper re-flashing during replacement is standard, not optional. |
What you pay depends on what’s on your roof and what’s under it. A simple single-story roof with good decking and standard architectural shingles lands at the low end. A steep two-story roof with rotted decking and upgraded materials lands at the high end. We’ll give you a written number for your specific roof before any work starts. Call (903) 499-4441 for a free estimate and we’ll put the price on paper.
One thing we will not do: give you a lowball quote over the phone and then raise it after you sign. Our pricing is written, itemized, and locked before work begins. That’s the Garrison Standard, and it applies to every job we do, including every full roof replacement in Dallas.
What the 365-Day Done Right Promise Covers
Every full roof replacement from Brennan Roofing Co Dallas comes with the 365-Day Done Right Promise. Here’s the deal in plain terms: if we install something wrong, or a part of the new roof fails due to our workmanship, we come back and fix it within one full year. In writing. At no charge. No arguing, no inspection fee, no “that’s not covered.” If it’s not done right, we make it right.
This is separate from the manufacturer warranty on the shingles themselves, which covers the material. Our promise covers the work. And if a repair fails during that year, the second visit is free too.
We can make this promise because we run the same process on every roof. Same step-by-step order, same background-checked technicians in uniform, same written price, same inspection. The Garrison Standard isn’t a slogan. It’s a checklist we follow.
Dallas Roofing Conditions We Plan For
Dallas roofs take a beating that most of the country doesn’t understand. Intense UV for nine months of the year. Hail season in the spring. Straight-line winds that rip loose flashing. And sudden temperature swings that make materials expand and contract. A full roof replacement in Dallas has to account for conditions that a roof in Michigan or Ohio never faces.
That’s why we pay close attention to three things on every Dallas replacement:
- Ventilation. Attic heat in a Dallas summer can reach 150 degrees if ventilation is wrong. That heat bakes shingles from underneath and shortens roof life. We check intake and exhaust airflow on every replacement.
- Flashing. Dallas houses usually have multiple pipe penetrations, vents, and chimneys. Each one is a potential leak point. We re-flash every penetration before the new material goes on.
- Impact resistance. Given the hail frequency in Dallas, we’ll show you Class 4 impact-resistant options from manufacturers like IKO and Atlas. These shingles are engineered to take hail hits without losing granules or cracking. They don’t make a roof hail-proof, but they buy you years of extra life.
FAQs – Full Roof Replacement
How long does a full roof replacement take in Dallas?
A standard full roof replacement on a single-family Dallas home takes 1 to 3 days depending on the size, pitch, and material. Most of our Dallas jobs are complete in 2 days. We’ll give you a timeline in writing when you get your estimate, and if it changes, you’ll hear it from us before the day starts, not after.
Is it cheaper to repair or replace a roof in Dallas?
Repair is cheaper in the short term if the damage is confined to one area, but on a roof past the 20-year mark, repeated repairs usually cost more than replacement within a few years. We’ll tell you honestly which one applies to your roof. If it can be repaired, we’ll say so. If it needs replacing, we’ll show you why. Call (903) 499-4441 for a straight answer with no pressure.
Do I need to be home during the roof replacement?
No. You can be home, but you don’t need to be. Most of our Dallas customers go about their day while we work. We’ll let you know when we start, when we’re done, and we’ll walk the property with you at the end. You’ll have a direct line to the crew lead throughout the job.
Will my insurance cover full roof replacement in Dallas?
If your roof was damaged by a covered event like hail or wind, your insurance may pay for a full replacement minus your deductible. We’re not an insurance claim processor and we don’t promise to handle your claim for you, but we do provide the photo documentation and inspection findings you’ll need to file a claim with confidence. The price goes in writing either way.
