What types of warranties are available for roofing products?

Some of the different product warranties offered in the roofing industry include Limited Lifetime, 50 Years, 40 Years, 30 Years, 25 Years, Accelerated, Prorated and Non-Prorated – to name several.

The best way to determine which warranty is right for you is to compare the warranties side by side and consider which elements best cover your interests.

What is a “Fully Transferable” product warranty?

“Fully transferable” means that the warranty can be transferred an unlimited amount of times and thus provides the same value to the next owner when you sell your property and the next owner sells it to the next buyer… and so on.

What is a "Non-prorated” product warranty?

Many warranties on the market are prorated in an accelerated manner. This means the manufacturer will cover less and less of the product replacement costs as time goes on.

Usually, more of the coverage is taken away during the early years of the product warranty. Non-prorated warranties provide full product replacement value to the length of the product warranty, not just “pennies on the dollar” after a few years

What are some of the limitations of product warranties?

It is important to understand the limits of product warranties. Usually, product warranties cover replacing product, but normally do not cover the labor to replace the product.

With many products, the cost to replace one defective product in the middle of the roof requires that a much larger section of the roof be exposed.

These costs are not covered by most warranties.

If your product warranty requires preventative maintenance, know what is required to keep your product warranty in effect and how much it will add the annual cost of your roof. Some roofing materials require extensive maintenance depending on the climate, while others require very little.

Some specific questions to ask are:

Does your product warranty require increased attic ventilation?

Many roofing products are affected by the attic temperature and inadequate ventilation will void your warranty.

Does the underlayment product (i.e. felt) have a manufacturer’s warranty?

Your roof will be exposed to harsh elements all year long. Your peace of mind should not be dependent upon a 1/8” membrane that is not designed for long term protection.

Ask about the product you are buying and how the contractor will install the product.

Make sure the product is installed in complete compliance with the manufacturer’s printed installation instructions. If the roof is not installed correctly, the manufacturer will normally void all product warranties.


What you should know about the company offering the product warranty.

It is important to know how long the manufacturer has been in business. Your product warranty is not much good if the company standing behind it goes out of business or changes ownership without transferring the product warranty coverage.

Ask for a copy of the product warranty and review it closely

What about verbal warranties?

Beware of verbal warranties. All reputable manufacturers will have a printed product warranty statement. Read the fine print, and if you can’t read it, get a magnifying glass and have a legal expert review exactly what you have signed up for.

Warranties are documents that extend to you the protection of your investment. So, it is important to ask the questions before you buy the product.

If the manufacturer is proud of their product warranty, they will gladly provide you a warranty to review and answer any questions you might have.

Why Ventilate?

More than any other part of your house, the roof is subject to extremely high heat, both on and under the roof deck. In the summer, on a clear 90°F day, the sun can heat the roof shingles to 170 degrees.

Left unvented, heat can build up to as high as 140°F inside the attic. Eventually this uncontrolled hot air can penetrate the home's living space, warming the area below and causing increased demands on air conditioners and increased utility costs.

A properly ventilated attic enables this extreme heat to escape outside.

The result: Lower air conditioning costs in the Summer.

In the winter, moisture from the well-sealed, well-insulated house condenses in the attic and settles in the insulation.

When wet, insulation loses its effectiveness (sometimes dropping to as little as one-third its original R-value) and allows valuable heat to escape through the attic.

Even worse, soaked insulation can stain or crumble ceilings. A properly ventilated attic provides an exhaust system, and moisture can escape.

The result: Better insulation performance and lower heating costs in the Winter.

An additional danger during the winter months is the formation of ice dams. Properly vented roofs prevent the formation of ice dams.

The result: Longer lasting roofs.

Of all the reasons to ventilate an attic, however, the most important is to preserve the structural integrity of the roof. At all times during the year, heat and moisture accumulate in every attic, and when left uncontrolled, excessive heat and moisture often result in significant damage to the roof and structure—reducing their normal life expectancy.

Proper ventilation validates the shingle manufacturer's warranty, and protects the roof and ceilings from both heat and moisture.

The result: Long life, beauty, and optimum performance from roofing and housing structure.

How Do Ridge Vents Work?

Ridge Vent works on the basis of several principles. Adequate soffit ventilation coupled with ridge ventilation produces a pathway for a continuous air flow along the entire underside of the roof deck.

Air flow is maintained two ways.

First, hot air naturally rises and exits out the ridge vent, pulling in cool air from below.

Second, positive airflow across the ridge of the house creates a "venturi effect", or a vacuum, which pulls air out of the ridge vent and brings in cool air from the soffits below. In calm or windy weather, the entire attic is vented by a constant flow of cooler, dryer outside air.

Will A Ridge Vent System Keep Out The Bad Weather?

(Excerpted from Canadian Roofing Contractor Magazine)
Before you are about to cut a slot into your roof for air to circulate freely, you may have a question about weather infiltration. Rest assured that ridge vent products are designed to keep wind, rain and snow, as well as insects, out of your attic.

For example, Roll Vent consists of a three-dimensional open nylon matrix bonded to a breathable nylon-polyester non-woven fabric. This design prevents the possibility of leakage commonly seen with other venting devices.

Roll Vent has been independently tested and has successfully withstood driving 110mph winds and a continuous water spray equal to eight-inch per hour rains.

However, in all cases, consult product technical bulletins available from manufacturers. Read them carefully as the ridge vent system you’re considering must serve as both a weather barrier and a vent.

What Are The Dangers of Ice Dams?

A major concern in prolonging and safeguarding your roof, especially in snow-belt and mountain areas, is ice damming. Ice Dams are created when melting snow freezes on the lower part of the roof, placing roof, walls, ceilings, siding, gutters and down-spouts at risk for costly structural damage.

Freezing occurs because the lower part of the roof is cooler than the ridge area. A ridge vent system helps reduce the possibility of ice damming since it delivers a constant flow of air that circulates under the roof.

Proper ventilation helps eliminate warmer upper areas and cooler lower areas that create the thaw/re-freeze cycle.

What is NFA?

Venting products are normally rated with a Net Free Area (NFA). The NFA is the open area that exists for air to pass through.

The key to effective venting is to balance the NFA of soffit and ridge vents. Ideally the NFA of the soffits should be equal or greater than that of the ridge vent. See our ventilation calculator to determine your ventilation needs.

Why Ridge Vent?

Ridge Vent has been proven to be the most effective attic ventilation method, for several reasons.

Ridge Vent is installed at the ridge-the hottest part of the attic.

Ridge Vent is continuous, and provides ventilation along the entire underside of the roof deck-where heat and moisture are at their maximum.

Ridge Vent requires no electricity.

Ridge Vent provides continuous air flow within the attic when combined with soffit ventilation.

Why Benjamin Obdyke Ventilation Products?

Benjamin Obdyke is the superior choice for ridge venting systems.

Benjamin Obdyke products are virtually invisible, due to their unique "shingle over" design.

Benjamin Obdyke is the innovator of the original rolled ridge vent.

How Do I Determine My Ventilation Requirements?

Many homes are improperly ventilated. Even if your attic area is presently vented, it should be closely checked to determine whether or not the present ventilation system is adequate and balanced.

Signs of improper ventilation, resulting in high moisture content in the attic, include:
Damp insulation
Unnaturally dark or discolored boards.
Dark streaks on roof boards around nails.
Orange resin beads on rafters signaling sweating wood.
Signs of moisture on roof boards & rafters.

In drastic cases of dampness, soft and crumbling boards will be evident, and structural repairs may be needed. In less drastic situations, the problems may be solved simply by installing additional ventilation.

It is first necessary to calculate your ventilation needs. First determine the square footage of your attic floor; then use the number to determine the required Net Free Area of your selected ventilation product. Net Free Area is the approximate clear opening of the ventilator through which air may move.

The space ventilated should have a minimum Net Free Area of 1/150*

This means that for each 150 square feet of attic floor space, 1 square foot of Net Free Area is required. The ratio can be reduced to 1/300 if:

1) there is a vapor barrier installed in the attic over the living space, or
2) there is a difference of at least three feet in height between the intake (under-eave vents) and the exhaust.

The total Net Free Areas of the intake and exhaust must be at least equal. Any excess Net Free Area should be at the intake.
* Check local codes.
