Q & A for Roofing in Caldwell County, North Carolina
When would a roofer install a new roof over an existing roof, without removing the old roof?
Installing a new roof without removing an existing roof is attractive to some homeowners because it saves money. Many roofers will install a new roof over top of an existing (depending on the material), but the best method for re-roofing is usually complete tear-off and removal of the old roof. Removing the old roof allows for inspection of the substrate, which is important to help determine if there are any existing roofing materials that are in poor condition.
What types of shingle styles are available from local roofing companies?
- 3-Tab Shingles – These are extremely common and one of the least expensive roofing options on the market. 3-tab is a good choice for homeowners primarily concerned with the cost of the new roof. 3-tab shingles typically offer a single layer of protection for your home and have shorter warranties. While less expensive initially, 3-tab shingles may not be a good choice for harsher weather climates.
- Architectural Shingles - These higher quality shingles are composed of two layers of material per shingle, so they offer a double layer of coverage. Architectural shingles usually have a longer duration on the warranty (i.e. 30 years).
What warranties do roofers typically offer?
There are two kinds of roofing warranties homeowners and business owners need to be aware of:
- Roofing Materials Warranty - These warranties are not actually offered by the roofing contractor, though the contractor can educate you on the different durations and types. Materials warranties are offered by the manufacturer of the materials you select. Whether you're installing a new metal roof, shingle roof, or tile roof, the materials used are typically guaranteed for anywhere from 10 years to a lifetime. Quality manufacturers such as GAF, CertainTeed, and Owens Corning and others all offer warranties on their materials. The duration of the warranty depends on the grade of material you select.
- Workmanship Warranty - These warranties are offered directly by the roofing company and typically protect the property owner against roof leaks or other issues caused by improper installation. Duration of these warranties often varies between 1 year up to 10 years. Be sure to get any guarantees or warranties offered by your hired roof contractor in writing to protect yourself.
