Small, localized repairs may be feasibly performed to exterior cladding - or maybe not. Proper documentation is key to avoid speculation and present objective examples with specificity to the actual project and its own unique complexities.

Smooth-roll modified bitumen cap sheets are required to have some sort of UV protectant applied to prevent premature degradation. This includes aluminum coatings, which commonly consist of asphalt, aluminum, and acrylic polymers. Upon large-diameter hail impacts, concentric fractures to the coating application can exhibit upon compression of the modified bitumen cap sheet. Commonly, this occurs at areas that are relatively unsupported or where not attached flush with the underlain substrate. In severe cases, the modified bitumen cap sheet can become bruised, fractured, or even punctured. It is necessary to identify whether impact energy resulted solely in fracturing of the overlain coating, or if the modified bitumen cap sheet sustained bruising, fracturing, or puncturing.

The profile of a roof deck can have a major impact on how water migrates throughout a roof assembly if breached. For instance, deck types like OSB, plywood, or concrete that are flush against overlain insulative or coverboard substrate(s) can increase likelihood of roof saturation and degradation, especially in the case of hygroscopic substrates like glass-mat gypsum, perlite or fiberboard products. Conversely, deck types like corrugated steel provide distance between an overlain substrate, effectively acting as a drainage channel via its flutes. Example No. 1 is a perlite board installed flush against a structural concrete deck. With a breached overlain roof membrane, infiltrated moisture increases until eventually, the hygroscopic perlite substrate is saturated and free water begins to gather. Being that the perlite is flush against the deck surface, moisture wicks in and migrates throughout the perlite substrate. Example No. 2 is a closed-cell SPF system installed against a corrugated steel deck. Of note, a polyester fabric was installed (black strands) to prevent the overlain SPF from being applied into the flutes. With a breached overlain system, infiltrated moisture can make its way to the bottom of the deck flutes, essentially draining into the interior at the nearest deck joint, bypassing much of the overlain substrate. Albeit a closed cell product, SPF can still break down and deteriorate with long-term moisture saturation. As evidenced here, the SPF is in great shape even though the interior directly below experienced heavy leakage due to an adjacent perimeter flashing breach.
