Roof Repair & Shingle Replacement in Dallas – Prestonwood

In the Prestonwood neighborhood of Dallas, one homeowner had two different trouble spots on the same roof — buckling shingles on the front elevation and matching damage on the back, with both areas actively leaking. A closer look during inspection connected the back-elevation leak to something less obvious than storm wear: the primary bathroom’s exhaust wasn’t venting through the roof the way it should have been, and the decking above it had paid the price. What started as a two-spot shingle repair turned into a full roof tune-up that addressed the actual cause, not just the visible damage.

The Challenge: Two Leaks, One Roof
This Prestonwood home had two separate trouble spots showing up on the same roof at the same time — buckling, damaged shingles on both the front elevation and the back, with active leaking reported at both locations. Having two independent leak points on one roof isn’t as simple as treating it like a single storm-damaged patch; each elevation needed its own inspection to confirm the extent of the damage and whether the two were actually connected or just coincidentally happening at the same time.
The Discovery: A Bathroom Vent That Wasn’t Doing Its Job
The front elevation turned out to be straightforward wind and wear damage to the shingles themselves. The back elevation was a different story: the decking above the primary bathroom had deteriorated, and tracing why led back to the bathroom’s exhaust fan, which wasn’t properly vented through the roof. Without a dedicated vent opening to the outside, moisture from the bathroom had nowhere to go but up into the roof structure — exactly the kind of slow, invisible damage that doesn’t show up until the decking underneath finally gives way.
The Solution: Patch Both Elevations, Fix the Vent, Tune Up the Rest
Both elevations got new GAF Timberline® shingles in Weathered Wood to match the existing roof, along with a full hip-and-ridge shingle replacement wherever damage was found. Above the primary bathroom, the compromised decking was cut out and patched, a new vent opening was cut into the back elevation, and a proper roof vent was installed to finally give the bathroom’s exhaust somewhere to go. The rest of the roof got a full tune-up at the same time — resealing pipe jacks and HVAC stack seals, clearing valley debris, checking for nail pops — and the chimney cap was primed and repainted while the crew was already up there.
The Results: Two Leaks Closed, One Root Cause Corrected
Both leaks are resolved, but more importantly, the back-elevation leak’s actual cause — a bathroom with nowhere to vent its moisture — is fixed rather than just patched over. The new roof vent means that problem won’t quietly resurface under a fresh set of shingles a few years from now, and the rest of the roof received the same full inspection and tune-up as the two problem areas themselves.
Before, During & After: The Prestonwood Roof Repair



The Phillips Way
How we handled every step of this project — from first inspection to final sign-off.
Step 1
Inspect & Document
Inspection covered both elevations independently, confirming buckling shingle damage on the front and back and tracing the back elevation’s issue to a bathroom exhaust that wasn’t venting through the roof, rather than assuming both leaks shared one cause.
Step 2
Consult & Confirm
With no insurance claim involved, the homeowner was walked through why two separate repair areas were needed, plus the added vent work for the primary bathroom, before any work began.
Step 3
Prepare & Protect
The crew coordinated driveway access for material delivery and staged to work both roof elevations in the same visit, per the standard property-access terms for tear-off and repair work.
Step 4
Install & Restore
New GAF Timberline shingles in Weathered Wood replaced the damaged sections on both elevations, along with a full hip-and-ridge shingle replacement. The compromised decking above the primary bathroom was replaced, a new vent was cut and installed for the bathroom exhaust, and the full roof tune-up covered pipe jacks, HVAC stack seals, valley debris, and nail pops — with the chimney cap primed and repainted in the same visit.
Step 5
Clean Up
All removed shingles, decking, and job debris were cleared from both elevations before the crew left.
Step 6
Walkthrough & Sign-Off
A final walkthrough confirmed both repaired elevations matched the surrounding roof and that the new bathroom vent was properly sealed and functioning, with sign-off before completion.

Why Proper Preparation Matters
Patching visible shingle damage without addressing what caused it only buys time until the same spot fails again. Above the primary bathroom, that meant tracing the decking damage back to a bathroom exhaust with nowhere to vent, rather than simply replacing the decking and shingles and moving on. Cutting a proper vent path through the roof before closing it back up is what keeps this particular repair from needing to be redone.
Materials Selected for Long-Term Performance
The replacement shingles match the home’s existing GAF Timberline roof in both product line and color, so the repaired sections on both elevations blend in rather than reading as a mismatched patch. The hip-and-ridge shingles are matched the same way, and the new bathroom vent is a dedicated roof vent designed for exhaust venting rather than a repurposed or improvised opening.
The Phillips Approach
Two separate leak points on one roof could have been treated as two unrelated shingle repairs. Instead, each elevation got its own inspection, and the back elevation’s damage was traced to its actual source — a bathroom that had never been properly vented through the roof — rather than stopping at the visible decking damage. The same full-roof standard applied everywhere else too, with the tune-up and chimney cap work handled in the same visit rather than treated as separate add-ons.
