Full Tear-off and Roof Replacement in Plano – Hills at Prestonwood

August 5, 2026
Roof Replacement in Plano - Hills of Prestonwood - Before Roof Replacement

This Hills at Prestonwood homeowner had been dealing with recurring roof problems for years, patching leaks and paying for repairs that never quite solved the underlying issue. After weighing a metal roof and finding it ruled out by neighborhood deed restrictions, she chose a roof replacement with Class 4 impact-resistant shingles built to hold up against North Texas hail and wind rather than another round of patchwork repairs.

Project at a Glance

  • Location: Plano, TX
  • Neighborhood: Hills at Prestonwood
  • Property Type: Two-Story Single-Family Residence
  • Project Scope: Full tear-off and roof replacement, synthetic underlayment installation, self-sealing valley waterproofing barrier, multi-size pipe jack replacement, static and powered attic ventilation installation, drip edge replacement, and hip and ridge shingle installation

The Challenge: Repairs That Never Quite Fixed the Problem

Before contacting Phillips, this homeowner had already been through repeated roof repairs that kept addressing the same problem areas without resolving them for good. The aging laminate shingles on this two-story home had reached a point where patching individual sections was no longer a reliable fix.

The homeowner looked into a metal roof, but neighborhood deed restrictions ruled that option out. That led to a conversation about shingle systems built for durability instead — specifically Class 4 impact-resistant shingles, which offer a higher level of protection against the hail that drives most roof damage in this area.

The Discovery: A Steep Pitch and Ventilation Overdue for an Update

Tearing off the old roof removed 44.18 squares of worn laminate shingle material and exposed a 10/12 pitch across the full 50.807-square deck — steep enough to require careful footing and handling throughout the project. With the deck fully exposed, the crew inspected it for soft spots or damage before any new material went down.

The home’s ventilation setup, including 10 individual pipe jacks and multiple exhaust units, showed worn seals that were heading toward active leaks even though they hadn’t failed yet. That made a full ventilation rebuild part of the scope rather than an optional add-on.

The Solution: A Full System Rebuild With Class 4 Shingles

Owens Corning® Roofing Materials Staged for Use

The crew installed 457 feet of galvanized drip edge in a T Bronze finish along the roof’s perimeter to direct water into the gutters without touching the wood fascia. Over the bare deck, we rolled out Owens Corning® ProArmor® synthetic underlayment across all 50.807 squares, replacing old felt paper with a tear-resistant layer that lays flat. In the valleys, where the most water runs during a storm, we installed 239 linear feet of Owens Corning® WeatherLock® Mat self-sealing waterproofing barrier, which seals tightly around every nail penetration.

The primary shingle layer is Owens Corning® Duration® architectural shingles in Sierra Gray, rated for winds up to 130 mph and certified Class 4 for impact resistance — the highest hail-resistance rating available under UL 2218 testing. To rebuild the ventilation system, we installed four box vents and two powered attic vents across the ridge lines. All 10 utility penetrations were fitted with new multi-size pipe jacks, sealed with Henry® 900 flashing and construction sealant, and the roof’s hips and ridges were finished with 499 linear feet of matching Owens Corning® ProEdge® hip and ridge shingles.

The Results: A Roof Built to Stop the Repair Cycle

Mid-Project on Roof Replacement

The Sierra Gray architectural shingles give the home a cleaner, more dimensional look than the laminate shingles they replaced. More importantly, the new roof addresses what the old one couldn’t: the Class 4 impact rating and rebuilt ventilation system are designed to hold up against hail and heat rather than needing another round of patch repairs.

The project passed final city inspection with full approval, and the completed installation carries Texas Department of Insurance certification for its Class 4 impact resistance rating — documentation that can support premium considerations with the homeowner’s insurer.

The Phillips Way

How we handled every step of this project — from first inspection to final sign-off.

Step 1

Inspect & Document

Our team documented the deteriorated laminate shingles and worn flashing across the full 50.807-square roof before recommending a replacement.

Step 2

Consult & Confirm

We walked the homeowner through shingle options, including Class 4 impact-resistant shingles, to find a system built to stop the repair cycle for good.

Step 3

Prepare & Protect

Protective netting and a dedicated dumpster were set up on-site to keep landscaping and the surrounding property clear of debris during tear-off.

Step 4

Install & Restore

Crews installed Owens Corning Duration Class 4 shingles, synthetic underlayment, valley waterproofing, and rebuilt ventilation across the steep 10/12 pitch.

Step 5

Clean Up

The crew swept the yard with magnetic rollers to clear stray roofing nails and metal debris from the tear-off.

Step 6

Walkthrough & Sign-Off

The city inspector completed a full review of the installation and issued final code approval before the project closed out.

Why Proper Preparation Matters

A roof this steep — 10/12 pitch across nearly 51 squares — needs a clean, total tear-off before anything new goes down. The crew removed 44.18 squares of old laminate shingle down to bare deck, inspected the wood for soft spots, and cleared all fasteners before installing 457 feet of custom-fit drip edge around the perimeter to keep wind-driven rain off the fascia.

Materials Selected for Long-Term Performance

Given this homeowner’s history of recurring repairs, the material selection focused on durability over the cheapest option. Owens Corning® ProArmor® synthetic underlayment provides a tear-resistant secondary barrier that traditional felt paper can’t match. The Duration® shingles carry a 130 mph wind rating and Class 4 impact resistance — the highest hail-resistance rating tested under UL 2218 — which directly addresses the kind of damage that led to the previous repair cycle.

The Phillips Approach

Rather than another patch repair, this project replaced the full system down to the deck: new underlayment, valley barrier, drip edge, ventilation, and shingles, rather than layering new materials over old problems. All 10 utility pipe jacks were replaced with new galvanized components, and the ventilation system was rebuilt with both static and powered venting to manage attic heat. The project was carried through city permitting and final inspection, closing out with full code approval.

Questions Related to this Roofing Project

Q: Why was a self-sealing waterproofing barrier installed in the roof valleys instead of standard underlayment?

A: Roof valleys handle concentrated, fast-moving water from multiple roof slopes converging in one channel, which puts more stress on that area than the flat sections of the roof. On this project, the team installed 239 linear feet of Owens Corning WeatherLock Mat self-sealing waterproofing barrier directly into the valley channels. The material bonds to the wood decking and seals tightly around every nail penetration when the shingles are installed over it, preventing water from migrating underneath even during heavy runoff.

Q: What does a Class 4 impact-resistant shingle rating actually mean for a homeowner?

A: A Class 4 rating is the highest level of hail-impact protection tested under the UL 2218 standard, which involves repeated steel ball drops simulating severe hail without the material cracking or splitting. This project used Owens Corning Duration shingles in Sierra Gray, reinforced along the nailing zone to absorb hail impact without fracturing. For homeowners, this generally means fewer hail-related leaks over the life of the roof, and in Texas, Class 4 certification can support premium considerations with some insurance carriers.

Q: Why did this roof need both static box vents and powered attic vents?

A: Proper attic ventilation depends on a balance of passive and active airflow to manage heat and moisture. This two-story home’s steep 10/12 pitch and large attic volume trap significant heat during North Texas summers. The team installed four static box vents, which let heat escape naturally through convection, alongside two powered attic vents that actively pull hot air from the highest points of the attic. Together, this reduces heat buildup that can shorten a shingle’s lifespan and add strain to the home’s cooling system.
