Warranty Coverage
Both Oakridge and Duration shingles are backed by a Limited Lifetime Warranty and a 10-year Tru PROtection® period, which covers labor and materials without proration. However, Duration shingles have the added advantage of being transferable if you sell your home, which can add resale appeal. This makes Duration a better long-term investment for homeowners planning to stay in their home for many years or looking to enhance property value.
Wind Resistance
If you live in an area prone to storms or high winds—like Houston or coastal Texas—wind resistance matters. Oakridge shingles offer wind protection up to 110 MPH, but can be rated up to 130 MPH with the use of 6 nails and starter shingles. Duration shingles come with a 130 MPH wind warranty right out of the box using only 4 nails, thanks to Owens Corning’s patented SureNail® strip, which reinforces the nailing zone for stronger holding power.
Impact Resistance & Insurance Discounts
If you live in a hail-prone area, your shingle’s impact rating can directly affect insurance premiums. Oakridge shingles do not have a special impact rating. Duration shingles, however, carry a Class 3 UL 2218 Impact Rating, which may qualify homeowners for insurance discounts and offers better protection from hail and debris.
Why Insurance Companies Offer Discounts for Class 3 & Class 4 Roofs in Houston
High Risk of Hail Storms in Texas
Houston and surrounding regions frequently experience severe hailstorms, especially in spring and early summer. Hail causes billions in roof damage each year, making Texas one of the most hail-prone states.
UL 2218 Impact Rating System
The Underwriters Laboratories (UL) developed the UL 2218 standard to test and classify roofing materials based on their resistance to hail damage. The test involves dropping steel balls from set heights and checking if the material cracks or breaks.
- Class 3: Withstands a 1.75″ steel ball dropped from 17 feet
- Class 4: Withstands a 2″ steel ball dropped from 20 feet (highest rating)
Lower Risk = Lower Premiums
Insurance companies reward homeowners who install higher-rated roofing (Class 3 or 4) because it reduces the chance they’ll have to pay out hail damage claims. These shingles often resist cracking, splitting, and granule loss better than standard shingles.
Texas Department of Insurance (TDI) Incentives
The Texas Department of Insurance allows carriers to offer discounts for homes using qualified impact-resistant roofing materials — especially Class 4. These discounts vary by provider but can range from 5% to 35% on the wind/hail portion of your premium.
This is a sample form from State Farm that we were required to complete to apply for a reduction in residential insurance premiums after installing impact-resistant shingles.

The Best Roofing System for Restaurants: Duro-Last PVC
When it comes to choosing the best roofing system for restaurant owners, having a reliable, high-performing roof is critical to the long-term protection of your business. That’s why our team of roofing experts recommend the Duro-Last roofing system as the ideal roofing solution for restaurants.
In this blog post, we’ll explain what is Duro-Last PVC (Polyvinyl Chloride), the features that come along with this roof system, and why it’s the best choice for your restaurant.
Let’s get started!
What is Duro-Last PVC Roofing?
The Duro-Last PVC roofing system is a custom fabricated system consisting of a flexible, single-ply thermoplastic membrane optimal for flat or low slope roofs.
The Components of PVC
Roof Decking
A roof deck is the foundation for your roof. Deck material is the important structural element that helps support the insulation and waterproofing (membrane layers). Whether the project is a membrane tear-off, complete reroof or new construction the roof deck will be visually inspected before the application of the roof system.
Main Types of Commercial Roof Decking:
- Plywood or Oriented Strand Board (OSB)
- Steel – cold-rolled, corrugated
- Structural Concrete
- Lightweight Insulating Concrete
- Gypsum
Base Layer is Metal Panel Decking, Repaired Section of Decking
Complete Tear-Off
Insulation
This is the key to energy efficiency. Polyiso (polyisocyanurate) is the most commonly used type of insulation. It offers the highest R-value of any rigid insulation. R-value measures the insulation’s resistance to heat flow. It’s important to note that for commercial buildings, there are minimum insulation R-value requirements that vary from state.
Popular Types of Roof Insulation Available:
- Duro-Guard ISO
- Duro-Guard EPS Fan-Fold
- DensDeck

Roof Membrane
Duro-Last’s roof membranes come in varying thicknesses, measured in mils. The membranes are available in custom-fit, prefabricated sections. This membrane is custom-fabricated in sections up to 2,500 square feet, fitting each roof precisely to its unique specifications. Instead of in the field, up to 85 percent of the seams are completed under ideal, factory-controlled conditions – reducing waste, saving on labor and preventing leaks.
Membrane Thickness Options:
- 40 mil
- 50 mil
- 60 mil
Installation Process
Mechanically attached: The membrane is securely attached to the underlying roof deck using plates and fasteners along the seams, then the overlapping seams are heat welded using a heat gun or welding machine.
Fully adhered: The membrane is bonded directly to the insulation or roof deck using a bonding adhesive or low rise spray foam, typically the low rise spray foam sticks better. Then the overlapping seams are heat welded using a heat gun or welding machine.
Accessories
The Duro-Last system also includes prefabricated flashing, boots for pipes, and vents, ensuring a perfect fit for each roof. Custom-fabricated flashings are manufactured with Duro-Last membrane material and feature a weft-inserted scrim which provides puncture and tear resistance along with tensile strength at transitions – the most critical areas of any roof installation.
Why PVC Duro-Last Is Ideal for Restaurants
Durability
Duro-Last roofs are recognized as the best roofing system for their excellent durability and long-term performance. Here are a few features that contribute to the durability of a Duro-Last roofing system:
- Various membrane thicknesses based on specific needs, with thicker membranes offering better resistance to wear and tear.
- Resistance to chemicals, oils, and grease—critical for restaurant kitchen exhausts that can cause buildup on the roof.
- The ability to withstand high winds and extreme weather conditions.
- Reduced on-site installation errors and minimized seam completion thanks to each roof’s prefabrication at a Duro-Last manufacturing plant.
- Resistance to punctures and tears from foot traffic, debris, or maintenance equipment.
- Heat-welded seams provide a watertight bond that protects against leaks and weather damage.
This positions Duro-Last as the best roofing system for commercial and restaurant environments.
Longevity
A typical Duro-Last roof has an impressive lifespan of about 20-30 years. This longevity is primarily determined by two key factors: the thickness (mil) of the membrane and the quality of the installation.
Thicker membranes offer increased durability, providing better protection against the wear and tear common in commercial settings, particularly restaurants. Proper installation is also critical, as Duro-Last roofs are prefabricated in a controlled environment to ensure precision and reduce on-site errors, further enhancing their lifespan. With the combination of high-quality materials and expert installation, Duro-Last is consistently the top choice available, offering restaurant owners a reliable, long-lasting solution that can withstand the demands of their environment, from heavy foot traffic to harsh weather conditions.
Energy Efficiency
The Duro-Last PVC roofing system is engineered for energy efficiency, significantly reducing your restaurant’s HVAC expenses. Its white, reflective membrane deflects the sun’s heat, helping your HVAC system operate more efficiently and lowering energy consumption. Additionally, the insulation’s high R-value enhances temperature control by reducing heat transfer, keeping your restaurant cool during hot weather and warm during colder months.
Fire-Resistance
The PVC formulation incorporates fire-retardant chemicals that enhance its resistance to combustion, prevent the spread of flames and also makes it self-extinguishing, adding an extra layer of protection to your roof. Duro-Last roofing membranes meet or exceed major national fire and wind code requirements, as well as most required regional approvals throughout the country.
Low Maintenance
Duro-Last roofs require minimal maintenance however, it is still important to keep your roof maintained and clean to maximize the roof’s lifespan. Here are a few maintenance tips to do so :
- Inspect for leaks in the building after severe weather storms
- Minimize foot traffic as much as possible
- Conduct a roof cleaning 1-2 times per year, checking for screws, nails, sharp objects, or outside debris (especially if building is surrounded by a lot of trees/vegetation)
- Schedule roof inspection at 15 years mark

What Materials Are Used in a Roof Replacement? (Houston Homeowners Guide)
When replacing your roof, it’s important to understand every material involved—not just the shingles you see on top. Each layer plays a crucial role in protecting your Houston home from wind, rain, heat, and humidity. At HHH Roofing & Construction, we believe educated homeowners make better roofing decisions. This guide walks you through all the essential components of a quality roof replacement.
Why It's Important to Know What's On Your Roof
Roofing isn’t just shingles. A complete roofing system includes decking, underlayment, ventilation, and more—each working together to protect your home. In Houston, where intense heat, heavy storms, and hurricanes are common, the right materials can extend your roof’s lifespan and even lower your insurance premiums. Knowing what’s on your roof helps you make informed choices when comparing quotes.
Essential Roof Replacement Materials (With Photos)
Every layer matters in a roof replacement. Below are the key materials we install on every project.
Roof Decking (Sheathing)
Roof decking is the wood layer that forms the base of your roof. It’s typically made from OSB (Oriented Strand Board) or plywood. During replacement, we inspect for water damage or rot and replace any compromised sheets.
When you have a roof that has been leaking for awhile it can eventually damage your plywood. If you are getting a roof replacement, you might have to replaced some of your roof’s decking. On average, most contractors will provide 2-4 sheets to repair any rotten plywood found during the tear-off.
Your roofing contractor won’t know exactly how many sheets will need to be replaced until they tear off all your roofing materials. This is why a roofing company will include in their estimate how many sheets they are going to provide and the cost for each additional sheet after tear-off.
Ice and Water Shield/Leak Barrier
This waterproof membrane is installed in the most vulnerable areas of your roof, such as valleys and around roof penetrations like vents and chimneys. Where two roof faces meet to form a valley, it’s crucial to guide water in the right direction and prevent pooling. Roof valleys experience constant water flow every time it rains, which increases the risk of leaks.
That’s why the ice and water shield is essential—it’s a self-adhering membrane specifically designed to create a watertight seal in high-risk areas. In Houston’s heavy rainstorms, this added protection is key to keeping your home dry.
Ice and Water Shield vs. Metal in Roof Valleys
When it comes to protecting roof valleys, homeowners often ask whether metal or an ice and water shield membrane is better. While both methods serve to direct water away from these critical areas, we typically do not recommend using metal valleys in Houston due to the extreme heat.
Metal in the valleys can expand and contract with temperature swings, which over time may cause warping, oil-canning, or even loosening of fasteners. This can create weak spots and lead to potential leaks, especially during Houston’s heavy rainstorms.
In contrast, an ice and water shield membrane self-adheres directly to the decking, creating a seamless, watertight barrier that adjusts to your roof’s movement without cracking or shifting. It’s designed to handle constant water flow—especially in roof valleys where two slopes meet—and provides long-term, low-maintenance protection ideal for Houston’s hot and humid climate.
Synthetic Underlayment
Synthetic underlayment sits on top of the decking and below the shingles. It adds an extra moisture barrier and protects your roof during Houston’s unpredictable weather. We use high-quality synthetic felt that’s more durable than traditional tar paper.
Drip Edge
It is code to have Drip Edge installed on the perimeter of your roof (Eaves & Rakes). Here is the following code on Drip Edge according to the International Residential Code 2015 (IRC 2015):
R905.2.8.5 Drip Edge
A drip edge shall be provided at eaves and rake edges of shingle roofs. Adjacent segments of drip edge shall be overlapped not less than 2 inches (51 mm). Drip edges shall extend not less than 1/4 inch (6.4 mm) below the roof sheathing and extend up back onto the roof deck not less than 2 inches (51 mm). Drip edges shall be mechanically fastened to the roof deck at not more than 12 inches (305 mm) o.c. with fasteners as specified in Section R905.2.5. Underlayment shall be installed over the drip edge along eaves and under the drip edge along rake edges.
Starter Strip Shingles
Starter shingles are installed along the edges of your roof to prevent wind uplift. They provide the foundation for your shingle rows and seal down the first course to avoid leaks.
Architectural Shingles (Main Roofing Material)
Architectural asphalt shingles are the most visible part of your roof. We install Owens Corning Oakridge® or Duration® shingles for superior performance and curb appeal. These shingles offer excellent wind resistance, vibrant color options, and long-lasting protection.
Check out our Blog for a Full Comparison on Owens Corning Oakridge Vs. Duration shingles
Hip & Ridge Shingles
These specialized shingles cover the peak and ridges of your roof. They’re designed to bend and protect the most vulnerable seams where roof planes meet. We install matching Owens Corning ProEdge® Hip & Ridge and Owens Corning RIZERidge® Hip & Ridge
Ventilation (Ridge Vents or Static Dome Vents)
Proper roof ventilation is one of the most overlooked—but most important—parts of a complete roofing system. In Houston’s hot and humid climate, good ventilation helps keep your attic cooler, reduces moisture buildup, and extends the life of your roof. Without proper airflow, heat and humidity can get trapped in the attic, leading to mold, wood rot, and higher energy bills.
There are three common types of attic ventilation used in residential roofing:
Ridge Vents
Ridge vents run along the peak of your roof and allow hot air to escape evenly across the entire attic. Because they sit at the highest point of your home, ridge vents are highly effective when paired with proper intake vents (like soffit vents). They also maintain a clean, low-profile appearance.
Static Roof Vents
Also called box vents or turtle vents, these are small, fixed vents installed near the roof ridge. They allow hot air to exit but do not actively move air. Multiple units are usually installed based on the size of the attic. They’re simple and effective but can be less efficient than ridge vents when not paired properly with intake ventilation.
Whirlybird / Turbine Vents
Turbine vents spin when the wind blows, creating a suction effect that pulls hot air from the attic. They don’t require electricity, and when installed correctly, they can move large volumes of air. However, they rely on wind to function and can wear out over time in Houston’s weather.
No matter which system you choose, ventilation must be balanced—with both exhaust vents (at the top of the roof) and intake vents (typically at the eaves or soffits). This balance allows for continuous airflow, which is essential for energy efficiency and roof performance.
| Feature | Ridge Vents | Static Vents (Box/Turtle) | Turbine Vents (Whirlybird) |
|---|---|---|---|
| Appearance | Low-profile, blends into roofline | Small square vents, visible on roof | Dome-shaped, noticeable on roof |
| Air Movement Type | Passive (constant airflow) | Passive | Passive with wind-powered suction |
| Effectiveness | High (when paired with intake vents) | Moderate (requires multiple vents) | High (with consistent wind) |
| Energy Use | None | None | None |
| Wind Dependency | No | No | Yes (works best in windy areas) |
| Maintenance | Minimal | Minimal | Moving parts may wear over time |
| Durability in Houston Heat | Excellent (no moving parts) | Excellent | Good (can wear faster under sun/heat) |
| Installation Cost | Moderate | Low | Low to Moderate |
| Best For | New roofs, clean aesthetic, max airflow | Simple roof replacements | Budget-friendly airflow boost |
Flashing (Pipe Boots, Chimney Flashing, etc.)
Chimney flashing is the metal installed where the chimney meets the roof, sealing the joint to prevent water intrusion. It’s usually composed of step flashing along the sides and counter flashing embedded into the chimney masonry. In Houston, with frequent rain and high humidity, poorly installed or aging chimney flashing is a common cause of leaks.
A pipe boot is a flashing device that seals around plumbing vent pipes to prevent water from leaking into your home. These penetrations are one of the most common sources of roof leaks if not sealed properly. There are several types of pipe boots, each with different materials and lifespans.
Metal Pipe Boots
Metal boots, often made of aluminum, are durable and resistant to UV rays. However, they typically rely on a rubber gasket around the pipe, which can dry out and crack over time—especially in Houston’s intense sun and heat. Regular inspection is important with metal boots.
Plastic Pipe Boots
Plastic boots are lightweight and cost-effective but tend to degrade faster under prolonged UV exposure. In Houston, where temperatures get extreme, plastic boots are more likely to crack and are not typically recommended for long-term performance.
Lead Pipe Boots
Lead boots are considered the most long-lasting option. The lead is flexible enough to form a tight seal around the pipe and is resistant to UV damage. Over time, the lead conforms to the shape of the pipe, creating a watertight bond that can last decades. These are ideal for Houston’s harsh climate.
Choosing the Right Roofing System in Houston
Houston’s intense UV rays, humidity, and hurricane threats require roofing materials that go beyond the basics. At HHH Roofing, we use the Owens Corning Total Protection Roofing System® to ensure every layer of your roof works together to protect your home and maximize longevity.

Duro-Last vs TPO | Which Is Better?
Is TPO or Duro-Last a better roofing system? Duro-Last is the better roofing system yet will be more expensive. In this blog post, we are going to break it all down for you from a contractor’s perspective that installs and repairs both roofing systems.
Material Differences
Duro-Last and TPO almost look identical both being white single-ply membranes. If you dive deeper into the material, what really sets them apart is their chemical compound.
Is TPO or Duro-Last a better Material? Duro-Last develops a higher quality material with a better chemical compound making them the better material. Their material is more expensive, and it really shows when we compare material vs. material.
Duro-Last Material Breakdown
Duro-Last is composed of PVC film laminated to both sides of a reinforcement fabric (weft-inserted scrim).
PVC Film: Proprietary thermoplastic PVC
formulation of resins, plasticizers, stabilizers,
biocides, flame retardants, and U.V. absorbents
Weft-Inserted Scrim: An 18 x 14 polyester fabric construction with weft insertion, composed of 840 x1000 denier threads, provides superior tear and puncture resistance. The polyester thread is treated to prevent wicking.
Duro-Last itself is a type of PVC roofing system and a Brand. Duro-Last carries manufacturing plants all over the United States and the closest one to Houston is located in Dallas.
In order to install a Duro-Last roofing system, you need to directly place an order through their company. This means you have to be certified through them and have an account with them.
Each Duro-Last system is custom fabricated for your roof which is why they can’t sell them at roofing supply stores.
TPO Material Breakdown
TPO (Thermoplastic Polyolefins) compounds are resin blends of polypropylene and un-crosslinked EPDM rubber and polyethylene
TPO is not a brand it is a type of material. There are different brands that create TPO membranes such as:
TPO material can be ordered from your local supplier because they are purchased in rolls. If you are here in Houston, you are able to find most brands at ABC Supply or Commercial Distribution Specialists.
How is each material installed?
Duro-Last & TPO are similarly installed most commonly using these methods:
Mechanically Attached
Fully Adhered
Both roofing systems utilize the same roofing accessories and similar Insulation types (Fan-Fold 1/2″ and Polyiso).
The biggest difference between the two is the way they come. TPO is a rolled good that comes in either 6′ x 100′ or 10′ x 100′ while Duro-Last is a prefabricated membrane made specific to the dimensions of your roof that just gets unfolded at the jobsite.
Due to Duro-Last being prefabricated, there are less seams to weld meaning there is a less likelihood for a leak happening in the seams.
When you are installing TPO you need to have a 6″ overlap between the rolls to go ahead and weld the seams. You have more seams to weld when installing TPO and more of a potential for possible leaks in the future.
That doesn’t mean TPO is hard material to install. It just means that TPO is harder to install when compared to Duro-Last.
Does Duro-Last or TPO cost more?
Duro-Last: They require you to order through the Duro-Last portal and use only Duro-Last accessories. The material itself is more expensive versus TPO membranes. Since you have to order the material to get it prefabricated there is a wait time and more delivery costs fees.
TPO: It is usually readily available at your local roofing supply and the material itself is less. Making it the more affordable option!
WARNING FOR OUR BUSINESS OWNERS
Both materials are great and if they were both installed correctly the Duro-Last system will give you several years more than a TPO system.
Issues come from the material not being INSTALLED CORRECTLY not from the material itself!
Find a great roofing company that can show you their past jobs and explain to you the breakdown of how they are going to install everything, but most importantly the warranty they are offering as a company not just material warranty.
