Window & Roof-Transition Waterproofing

Assessment and repair of window-perimeter seals, storefront joints, wall penetrations, and roof-to-wall transitions. Full-roof coating work is addressed on the roof coatings and restoration page.
Scope details
We assess window-perimeter seals, storefront frame-to-wall joints, wall penetrations, and roof-to-wall transitions where water may enter a commercial building. The repair plan follows the affected assembly and connected details, not only the location of the interior stain.
Roof-edge flashing, coping, and adjoining wall conditions are reviewed together where appropriate. For coating a roof surface, use commercial roof coatings and restoration; for a roof leak requiring diagnosis, use commercial roof repair.
