Tile roofs are cheaper in advance. In most cases, roof and metal installation are more expensive than asphalt. However, there are expensive architectural shingles that cost more than lower-cost metals, such as aluminum. This is especially important in areas prone to wildfires because if hot ash or embers fall on a metal roof, it is much less likely to catch fire than tile roofs.
Welcome to the start of a seven-part series on the most common questions homeowners have about metal roofs versus asphalt shingles. Homeowners, tired of the constant rotation of tile replacement, are looking for better roofing options. Limited Skilled Contractors — Finding a qualified and experienced metal roofing contractor or installer will make or break an installation, especially since almost all potential problems with the metal roof are due to some type of installer error. With the included fixtures, a metal roof can cost about the same as a tile roof in an average home, or within a few hundred dollars.
Architectural shingles, also known as “laminated” or “dimensional” shingles, are composed of the same elements as their traditional counterparts, but they are heavier, thicker and more expensive. Since metal can be installed on top of an asphalt shingle roof (see local building codes for possible weight limitations), you'll save labor and disposal costs, but keep in mind that you'll need to purchase and install wooden straps (we recommend 1×4 pine with a gap of 2 feet in the center) to provide a uniform base for the metal panels. Because metal is highly reflective, it will absorb less heat, which will help keep the roof cooler than most other types of roofs. This is based on a standing seam metal roof (the recommended choice for residential roofs) and all 3 types of asphalt shingles.
VARIETY OF APPEARANCES: Metal roofs come in many shapes and sizes, ranging from panel systems, such as standing seam metal roofing systems, to exposed fastener systems. Consequently, many homeowners are investigating the possibility of metal roofing for their homes and, of course, the cost of the product is a necessary component of any research effort. An additional cost you may incur that is not reflected in the quote would be to remove and dispose of old shingles if you replace them with more asphalt shingles. Not only does your roof protect your home and interior items, but it also keeps you and your loved ones safe, so choosing the right roof for your individual needs is vital.
Most estimates are produced between 40 and 70 years, but as materials continue to improve, the lifespan of newer metal roofs is expected to increase, not decrease. Having a tile roof installed definitely has a lot of benefits, most of which depend on its low initial cost, ease of installation, and access to materials. Metal roofs tend to be more complex because they use special techniques and equipment, such as profiling equipment, that require a more skilled installer than a tile installation.
