Solar panels are typically anchored to the roof using mounting systems specifically designed for solar installations.  These mounting systems provide secure attachment and ensure the stability of the panels.  The specific method of anchoring depends on the type of roof and the mounting system used.

For sloped roofs, such as tile roofs or asphalt shingle roofs, the most common method is to use roof flashing and brackets that are attached to the roof structure.  These brackets are then used to secure the rails or frames that bracket the solar panels.  Roof flashing is installed underneath the roof shingles or tiles to seal any penetrations and prevent water leaks.

For flat roofs, ballasted mounting systems are commonly used.  These systems use weighted blocks or ballasts to hold the solar panels in place.  The weight of the ballasts provides the necessary stability without penetrating the roof surface.  In some cases, flat roofs can also utilize penetrating mounts that are secured directly to the roof structure.

It's important to consult with a professional solar installer who can assess your specific roof type and recommend the appropriate mounting system and installation method.  They will ensure that the solar panels are securely anchored while minimizing any potential damage to the roof.
