Whether the goal is preventative maintenance, re-roofing or new construction, roofs like people, require physical checkups. No two roof top assemblies are the same; therefore each requires a different prescription. Design and specifications address these specific needs. A review of "as built drawings" and a field inspection to examine all of the structure's components and conditions are a necessity when selecting a suitable roofing system to best suite the needs of the building. Whatever your roof needs, Allied is here to specify the correct prescription for those precise requirements.
