Roofing is typically evaluated during a general home inspection performed for the buyer. Between sales however, homeowners typically do not consider the condition of their roofing until raindrops are falling indoors.
Considering extensive damage that a roof leak can cause, a visual inspection should be performed at least once every ten years, especially for asphalt shingles. Inspection should also be performed after storms with very high wind speeds. Knowledgeable homeowners can perform the inspection, although a qualified roofing professional should be considered.
• Roofing Materials
If inspection shows that new roofing should be installed, homeowners may be surprised to learn that there is a variety of roofing materials available other than the "standard" asphalt shingle. These materials can provide greatly increased lifespan and dramatically improved appearance.
In addition to cost, selection of the most appropriate roofing material requires consideration of other factors, including lifespan and climate conditions. The following materials can be used for residential roofing:
• Architectural asphalt shingles
• Standing seam metal panels
• Clay or concrete tiles
• Condition and Strength of Roof Framing
If the weight of new roofing is significantly greater than the weight of existing roofing, thorough evaluation of existing roof framing must be performed to determine if reinforcement may be required. Basic inspection can usually be performed from inside attic space, if available.
• Ventilation and Insulation
Adequate ventilation and insulation of spaces between roof sheathing and ceiling below must be provided. Remedial work may be necessary if the house was originally constructed without adequate ventilation or insulation.

Standing seam metal roofing is generally thought of as being only for commercial buildings. However, standing seam is being considered more often for homes by architects and owners due to long lifespan, pleasing appearance in many applications and relatively low cost compared to other high-end roofing materials.
