What material will receive the repair?
We identify the installed covering where possible and inspect its seams, fasteners, flashings and attachment. Existing patches can hide earlier removal or different materials, so we examine their edges rather than placing a new layer over an uncertain surface. A permanent repair needs compatible material and a prepared boundary. Where the roof system is not confirmed, we use the available records and field observations before specifying the joining method or ordering product.
For a membrane seam, we check whether the sheet is clean, secure and suitable for the repair method. A commercial roof seam repair may need removal beyond the visible split if the adjoining sheet is loose or damaged. At a wall, curb or pipe, the repair must meet the component it surrounds. Our penetration flashing work includes the roof-side transition; a leaking wall joint or equipment defect remains a separate task when it is outside that connection.
