Common Questions of Roofing Contractors in Minot, ND
Will roofing companies install a new roof over an existing roof?
It depends on the circumstances of your particular roof and material. In some cases you can install a new roof over an existing roof and that is a cheaper option because you save on the cost to remove and dispose of the old roof. But the best method is often 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.
How much does it cost to install a new roof?
The cost of roofing varies by a number of factors, including:
- Size and shape of your roof
- Slope of your roof - Steeper sloped roofs are more challenging to work on and may require higher labor costs.
- Number of existing roof layers to be removed - Tear off and proper disposal of existing roof layers is a significant part of the cost of a re-roofing project. More layers cost more to remove and more to dispose of.
- Type and grade of roofing material selected - Metal roofing lasts longer than shingles, but costs more. Architectural shingles cost more than 3-tab shingles. Specialty roofing materials like slate roofing or shake roofing, cost more for the material and the installation than a basic shingle roof installation.
How should I compare estimates between two roofers?
Roof replacement estimates from different roofers may vary significantly in price. When comparing two roof estimates, it's important to consider the type and grade of material being quoted in each estimate. Also, it can be a mistake to select a contractor based on price alone, because roofers may vary significantly in their credentials and in the quality of work they will provide. Select the company that offers the best overall value. Licensed, insured, and professional service at a fair price will almost always end up a better deal than an unprofessional roofer offering a cut-rate quote.
What roofing warranties are typically provided?
Roofing materials warranties are actually provided by the manufacturer of the shingles, tile roofing, or metal roofing material. Manufacturers usually offer different warranties depending on the grade of material you select. Less expensive shingles, tile, or metal roofing, usually carry a shorter warranty, as you might expect. The duration of these manufacturer warranties may be anywhere from 5 years up to "lifetime."
An additional warranty may be offered directly from the local roofer. A "Workmanship Warranty" or "Workmanship Guarantee" is a warranty that essentially guarantees that the roof installation was done properly. Depending on the language in the warranty, any roof leaks or other problems related to improper installation may be covered by the roofing company. These warranties, if offered, are typically anywhere from one to ten years.
