Understanding Manufacturers’ Warranties On Asphalt Shingles

All Around Roofing: Honest Roofers Denver CO

A roof failure can result in costly damage to interior and exterior structural components as well as furnishings. Manufacturers of asphalt shingles understand that homeowners want to feel secure that they have chosen the best shingles. Therefore, they often stress the length of their warranties in their product names or advertising materials. What many homeowners do not realize, however, is that these warranties typically contain a number of exclusions and conditions. As asphalt shingles continue to be a popular choice for Denver roofing systems, understanding more about manufacturers’ warranties may help homeowners make the best choice.

A manufacturer’s warranty on asphalt shingles covers defective products. Manufacturing defects are uncommon, but there are several things that can go wrong during the manufacturing process. For example, a splice joining two rolls of the fiberglass mat used as backing, missing sealant or improper granule application can result in a failure of the shingles.

A newly installed roof will have a “honeymoon period” of two to five years. During this time, the manufacturer will typically pay the full cost of the replacement shingles and accessories, such as underlayment or flashing, as well as the labor to install the new shingles.

However, the warranty may not cover the removal of the defective shingles or the disposal fees. After this initial period, the manufacturer usually prorates the amount paid. To illustrate, if the shingles carried a 50 year warranty and failed after 25 years, the manufacturer would pay 50 percent of the product cost.

Manufacturers’ warranties must detail the specifics required to prevent invalidating the guarantee. The roofing contractor must install the shingles precisely as the manufacturer instructs. If the warranty states that the shingles cannot be applied as a layover, doing so can give the manufacturer grounds to deny a claim. If the manufacturer requires that the attic have a specific number of cubic feet of ventilation, ignoring the requirement can void the warranty.

The manufacturer’s warranty will not cover damages that result from hail, winds that exceed the shingles’ rating or fire. It will not cover damages caused by things such as falling tree limbs or someone walking on the roof. Many warranties are valid only for the original owner, but some may be transferable to the next owner. Virtually, no warranties can be transferred repeatedly.

Because warranties vary greatly by manufacturer and shingle style, it is important for homeowners to read the warranties for each type under consideration. It is also critical to choose a reputable, experienced roofing contractor to ensure that the new roof is properly installed.
