Commercial Roofs
The top of a shop, office block or warehouse looks flat to the eye, though it carries a slight fall toward the drains; the covering must hold back water that lingers rather than sheds quickly. A membrane is a continuous waterproof layer rolled out, welded, glued or sprayed over insulation and a structural deck; the three most common types are built-up, rubber and thermoplastic. Building owners often use the words flat, low-slope and membrane as though they all meant the same thing; the terms overlap, though each points to a different part of the picture. Readers who look up Commercial Roof Contractors and Commercial Roof Installations often want to know who handles a building like theirs.
