A roof paneling system includes a roof panel comprising an open-cell inorganic foam. The foam can decrease hydraulic conductivity of the roof paneling system, filter rainwater falling on the roof, and reflect excess heat. The open-cell inorganic foam preferably comprises a ceramic or glass, and has a porosity of at least about 20%, a mean pore size less than about 10 mm, and a thickness of at least about 10 mm. The foam can include a hydrophilic compound that further decreases the hydraulic conductivity of the foam. Optionally, the foam can have a reflectivity of at least about 20%.
