Exclusive Lifetime Warranty

In addition to the manufacturers warranties, Maggio Roofing offers an exclusive lifetime warranty on selected roof systems (for residential properties only). This warranty covers both labor and materials for the life of the property. The warranty is limited to the purchaser and is transferable one time for a small administrative fee. This means that if you choose one of the selected roof systems, you can rest assured that you will never have to purchase another roof for your property.

Included in this warranty is our maintenance program. This means that we will visit your roof twice a year, at no cost to you, to make sure that your roof is weathering properly and that any problems are detected and repaired before they cause damage. All of this is done at no additional cost!
