The Difference
is in the Warranty

Roof Warranty & Attachments
Included vs Overburden


The owner has a roof warranty and a need to add something to the roof

The owner wants needs to install attachments and wants to maintain the roof warranty


Purchase a product from (or covered) by the roofing manufacturer

OR Purchase a 3rd party product and coordinate warranty coverage with roof manufacturer

  • Roof manufacturers require prior approval for 3rd party products on each project

  • Unless there is a letter from the roof manufacturer stating otherwise

  • Rooftop PV projects generally require additional documentation and installation steps

  • Alterations to the roof (including attachments) are generally classified as:

  • Voided

  • Overburden

  • Maintenance Item

  • Included

  • The roof manufacturer believes damage to the waterproofing is imminent

  • If the installation proceeds, the warranty is immediately cancelled

  • This is a RARE occurrence

  • A good example is wanting to turn the roof into a Go-Kart track

  • Overburden is applied to anything not sold (or covered) by the roof manufacturer

  • Mounting solutions, HVAC Units, Security lights, Portable Toilets, Billboards, etc

  • If there is a leak, the owner pays for:

  • Removing the overburden to assess, any issues from installation or traffic, any leak caused, and reinstallation

  • For large overburden, like rooftop solar, this can be cost prohibitive

  • Maintenance items are sole responsibility of the owner

  • Maintenance items are not covered in the warranty – even if they are sold by the roof manufacturer

  • Failure to maintain the items listed can result voiding the warranty

  • Any attachment with sealant, caulking, gaskets or compression fittings is considered a maintenance item

  • Adding these solutions reduces coverage and adds liability

  • The attachment is included in the roofing warranty as a single-source coverage

  • The attachment is included in the roofing warranty as a single-source coverage
