Our Lifetime Limited Warranty on Quarrix Composite Tile delivers peace of mind for decades to come. To submit a warranty or download warranty information see our Warranty Information.

A properly ventilated attic will extend the life of your roof. Without ventilation, moisture can accumulate and cause the roofing materials to deteriorate over time.

Building codes require that the 1/300 rule be adhered to and in some cases the 1/150 rule. This means that for every 300 feet of attic space, there should be 1 square foot of ventilation. Different products have different amounts of ventilation measured by their NFA, so you will want to make sure that you are using the correct amount of the product to provide enough airflow to meet the 1/300 or 1/150 rule. Check out our Ventilation Calculator for an easy way to determine how much ventilation you need.

Yes, for two reasons:

1. Quarrix ventilation products don’t have external baffles that can be clogged with leaves, etc.
2. The most crucial element to the performance of a ventilation system is that it is in balanced. If an attic has a properly balanced system, the airflow will move from the eaves and the bottom of the attic to the top, pushing out heat and moisture in a natural flow using air pressure, thermal effect and diffusion. If the system were to be unbalanced, and the NFA at the ridge is higher than at the eave, a reverse airflow can occur causing an opposite effect to what is desired. Baffles have no effect on achieving a balanced system. For a system to be in balanced there must be an equal or greater amount of intake at the eaves than what is being exhausted at the ridge.

Yes. Even though the attic is sealed, moisture can still become trapped beneath the roof decking and cause it to rot. If the conditioned space is properly insulated and sealed, you can still vent the roof deck without negatively impacting the conditioned living space.

Water stains or dark spots on the ceiling are a common sign that there is moisture in the attic and that it may not be properly ventilating. Additional signs include discoloring, curling, and decaying of the shingles as well as the formation of ice dams. 

In the balanced ventilation system, intake and exhaust vents work together to remove moist air from the attic. Air flows from the exterior of the home into the attic through the intake vents and forces moist interior air out of the exhaust vents, assuming that the system is balanced. If there is more exhaust ventilation than intake ventilation, an opposite effect can occur where air enters through the exhaust vents into the attic and prevents moisture from escaping.

A balanced ventilation system will be evenly divided between intake (50%) and exhaust (50%) ventilation. If the system cannot be balanced, you should use more intake ventilation but should not exceed a ratio of 60% intake ventilation to 40% exhaust ventilation. The amount of intake and exhaust ventilation you have is determined by the amount of Net Free Area (NFA) provided by the ventilation products used, so the amount of NFA at the soffit or eave (intake) should match the amount of NFA at the ridge (exhaust).

Yes! Our ventilation and composite roofing products have been tested and obtained numerous building product certifications. Whether its hurricane force winds and rain, extended UV exposure, extended weathering, or a variety of other extreme conditions, our products have proven that they are ready for the challenge. View our product pages for certifications relating to each product.

No. Ventilation types should not be mixed because short-circuiting can occur. For example, if a ridge vent and static vent are used together, the ridge vent may draw air from the static vent and vice versa which neglects ventilation of the attic space outside of the small area near the two vents.

Yes! A common misconception with attic ventilation is that more is better. Too much ventilation increases the likelihood that the system will be unbalanced and the exhaust vents at the peak will actually draw in air along with rain and snow. Additionally, more vents on the roof mean more penetrations in the roof deck that are susceptible to leaks. 

There are options for on-roof intake ventilation for those that do not have eaves and soffits. Quarrix offers the OffRidge Intake & Exhaust Vent which is installed on the lower third of the roof and provides the needed intake ventilation to move the moist air out of the attic through the exhaust vents.

The weather-blocker membrane material used in StormStop® is a spun-bound non-absorbent plastic that will not allow matter such as dirt or loose insulation to lodge within it. Twenty-nine percent of our membrane is fiber. The other seventy-one percent is open. This lightweight membrane makeup allows air to pass through but stops water. Water pools on the surface of the membrane but is not allowed to penetrate it.

No. Given the features of the StormStop® weather-blocker membrane, airflow is determined by measuring the Net Free Area of the vent (use the smallest cross-sectional opening), the slot width, and the ventilation at the eave or soffit. The recommend slot width for installation of StormStop®, when used with a balanced ventilation system, provides adequate airflow for efficient and effective ventilation.

Quarrix Ridge vents work on hip, and OffRidge vents work on eave intake, ridge exhaust and shed applications. Quarrix Ridge vents also work under various types of roofing materials such as flat tile, cedar shakes and shingles, stone-coated steel and metal.

High-density polyethylene (HDPE) resin as the base blended with fire retardant (made with recycled content) and UV stabilizers.

• Fuel Efficiency – Quarrix Composite Tile is 67% less weight than natural concrete/clay tile equally the typical weight of shingles. Weight advantage means more square footage on a truckload, which requires less transportation per roof.
• Manufacturing Process – Regrind plastic used in new products 10-20%. Reuse 100% of materials in plant (Drill tools and other parts) No in-process plastic from our plant goes into landfills.

High-density polyethylene (HDPE) is a UV-resistant polyethylene thermoplastic made from petroleum. The extremely high molecular weight of HDPE combined with its very low coefficient friction provides excellent abrasion resistance preventing gouging, scuffing and scraping. HDPE maintains all its properties at extremely low temperatures so no cracking occurs. It is resistant to corrosion from moisture and water, including salt water. HDPE is one of the highest impact resistant thermoplastics available, which is why many of our products including StormStop Ridge® Vent, OffRidge Intake & Exhaust Vent, and Composite Roofing are made from it.

Net Free Area (NFA) or Net Free Ventilating Area (NFVA) is the total unobstructed or free area through which air can enter or exhaust in a non-powered ventilation system.

Quarrix composite roofing should not require annual maintenance, but this is determined by the environment in which it is installed.

No. For more detailed information contact your insurance company.

Simply put, the look. Quarrix composite roofing emulates the beauty of traditional tile products like no other while also providing superior performance across all temperature and climate zones.

Also, with Quarrix Composite Roofing, the existing roof does not need to be reinforced as with natural concrete/clay tile. Our lightweight makeup also allows for easier installation compared to the natural tile. It can be cut or fastened with common power tools. With Quarrix Composite Roofing, you get the natural look without the weight challenges. You can also walk on Quarrix Composite Roofing with much less risk of breakage, unlike the natural products which are extremely fragile.
