Asphalt shingle is made of felt or fiberglass that is coated with tar and then covered with tiny stones that are literally glued onto the surface. Over time, the stones wear away, the shingles deteriorate, come apart, and the roof begins to leak.
Asphalt singles have an average replacement lifespan of 8-12 years. In this timeframe Asphalt shingles:
- Lose granules
- Attract moss
- Blow loose in the wind
- Hold snow and decay
- They even fall off their nails
- Begin to curl
- Are non-insulating
- Are combustible
- Are heavy in weight
- Wood shingles curl and warp
- Heavy tile products can be a hazard
A wood roof requires a tremendous amount of maintenance. So it’s expensive to keep up. Over time, decay accelerates, the roof becomes unsightly, and it eventually fails.
Clay or concrete roofing tiles have their own set of problems, which includes water intrusion due to their porous make up. The roofing tiles become cracked by moisture seeping through the pores during the freeze/thaw cycle. Once the tile is cracked, water damage can occur before the homeowner realizes there’s a problem.
When steel is exposed to the elements, it rusts. The steel deteriorates and flaky red granules appear in the affected area.
As you can see, a Classic aluminum roof is by far the smart choice.
