Disadvantages of Stone Coated Shingles
There are some disadvantages to stone coated steel roofing. The upfront costs are more than regular asphalt roofing. Natural stones used may create color inconsistencies. The panels overlap and do not interlock, which can create problems if snow, rain or wind get through. This type of roofing uses exposed fasteners, which can rust in time due to water exposure or trap moisture within. The batten type systems are prone to moisture and condensation, which can rot in time. Stone coated shingles are somewhat new; not every roof installer may know how to install them properly.
The bottom line is that, although stone coated steel roofing is fairly new, the benefits far outweigh the drawbacks. Although finances and budget do come into consideration with steel roofing, it is a better choice for builders who have the extra money to install this kind of roofing. Stone coated steel roofing will stand the test of time and far outlive asphalt shingles or cheaper roofing methods. If the home or building the roof is being installed in has a strong resale value, then this may be a good option. It is one of the longest lasting, most durable roofing systems on the market today.
