Many apartment buildings have flat or slightly sloping roofs, similar to larger commercial buildings. Most town-homes have pitched roofs, similar to single-family residences.
Flat Apartment Building Roofs are commonly installed with a Single-Ply Membrane, a flexible sheet of compounded synthetic materials that are manufactured in a factory. There are three common types of membranes: thermosets, thermoplastics, and modified bitumens. These materials provide strength, flexibility, and long-lasting durability. The advantages of pre-fabricated sheets are the consistency of the product quality, the versatility of their attachment methods, and, therefore, their broader applicability. They are inherently flexible, used in a variety of attachment systems, and compounded for long-lasting durability and watertight integrity for years of roof life.
For Pitched Roof Townhomes, Asphalt products are the most commonly used roofing material. Asphalt products include shingles, roll-roofing, built-up roofing, and modified bitumen membranes. Asphalt shingles are typically the most common and economical choice for this type of roofing. They come in a variety of colors, shapes, and textures.
