Type of roofing, quality of material, and exposure to harsh weather elements among the top are several factor that determine the life expectancy of your roof. a roof can last anywhere from 10 – 100 years with regular maintenance ad normal weathering factors.
Built up roofing is a common roofing material that usually lasts 12 – 20 years, metal roofing 15 – 40 years, wood shake or shingles 10 – 40 years, asphalt shingles 15 – 20 years, and specialty material like slate up to 100 years under good conditions.
A small crack in roofing material that may not be visible may cause leaks that water may collect in an adjacent area. A close inspection of the roof may be necessary.
To avoid further damage to the roof or personal injury to the homeowner caused by trying to inspect it his or her self, it is better to call a certified roofing contractor. Due to constant weathering by sun, heat, rain, snow, hail, wind, and cold that can cause roofing material to break down, roof inspection should be performed annually. For this matter, a certified roofing contractor will know what to look for.
In order to prevent over-heating and moisture retention, which are two factors that can cause a roof to break down prematurely, a roof and soffit system should be properly vented.
Selecting a Qualified Roofing Contractor
Various services are offered by a certified and experienced contractor such as completely tearing off an old roof and replacing it with a new one, and inspecting and “certifying” an existing roof. Next is a process in which the roof is inspected and “guaranteed” to function properly for a certain period of time which usually takes 2 years. Any necessary roofing repair during that period is the contractor’s responsibility.
A certified contractor will ensure there is adequate venting and knowledgeable about roof system types, materials and installation procedures that best suited each project.
Ask these questions to a potential roofing contractor:
– Are they licensed and bonded?
– What is the liability insurance coverage they carry? Is it up to date?
– Which roofing product manufacturers they are licensed and approved by?
– Are they a member of any regional or national trade organizations?
In order to find a certified roofing contractor, several resources are available such as referrals, local government licensing agencies, and web sites that offer contractors for hire, or a list of contractors who are licensed and bonded.
