Shingle Roofers
The common residential shingle starts as a reinforcing mat, which is coated with asphalt and then surfaced with mineral granules, so the whole shingle depends on all of them. Granule loss is the clearest sign that a shingle is wearing out, and it pays to think it through.
Flat shingles of this style are economical but wear out sooner than thicker kinds, and it remains a reasonable choice in some situations. Architectural shingles are made of two or more laminated layers that give the roof depth and shadow, and colors come in a wide range. The top of the range offers the richest textures and the greatest thickness, so the roof feels more substantial.
