When making any major purchase, the warranty is one of the most important things to consider. Your Colorado roof is no different. If you’re shopping for Denver roofing, you’ve surely seen some different words thrown around when talking about warranties.
What’s the difference between “Workmanship” and “Product” coverage? “Prorated” and “Non-prorated”? Should you spring for an extended roof warranty? Read on to find out!
The type of warranty on your new roof will depend on (A) your contractor and (B) the manufacturer of the product itself. Some products come with a longer warranty due to their durability and features. Your contractor will likely have product supply partnerships with manufacturers allowing them to offer special warranties.
One important distinction is between Workmanship Coverage and Product Coverage. The Roofing Product Warranty is on the actual roofing products themselves – your new shingles, underlayment, etc. If these “ingredients” of your roof ever fail within the warranty period, the manufacturer will replace them. A Roofing Workmanship Warranty covers the installation. If your new roof fails due to an application error within the Workmanship Warranty period, your contractor will be obligated to fix the problem.
For example, when you choose to have Owens Corning roofing products installed by Metro, you’ll want to know about the roofing product warranties that Owens Corning offers as well as the roofing workmanship warranty that Metro offers.
There are two main types of roofing warranty: Prorated and Non-prorated.
As your roof grows older, a prorated warranty covers a smaller percentage of the repair costs. It might cover the workmanship, but generally does not cover the entire cost of repair or replacement due to factors like material cost.
A non-prorated warranty covers workmanship as well as products. In some cases, it may be for a shorter period than a prorated warranty, but because the manufacturer will replace or repair the product at no additional cost, a non-prorated warranty is the better choice.
The main difference between the two is that as time continues, a prorated warranty will cover less of the material cost for repair or replacement. Always ask about warranty information when shopping for a roof. Your contractor is responsible for their workmanship, and the material warranties from the manufacturer are only valid so long as your roof has been installed correctly.
