While it is challenging to determine the exact roof type of a house without physically inspecting it, there are a few methods you can use to make an educated guess based on external visual cues:
Observe the angle: Stand at a distance from the house and observe the roofline. A pitched roof typically has a noticeable slope, while a flat roof appears horizontal or nearly horizontal. Look for any visible signs of incline or angle in the roof design.
Consider the drainage system: Look for gutters, downspouts, or visible drainage pipes. Pitched roofs usually require a more elaborate drainage system to manage rainwater runoff due to the sloping design. In contrast, flat roofs may have fewer or no visible drainage elements since they rely on internal drainage systems or scuppers.
Look for dormer windows: Dormer windows are typically found on pitched roofs. These are structures that protrude from the roof, creating additional space or windows in an attic or upper floor. Their presence often indicates a pitched roof design.
Study the architectural style: Certain architectural styles are commonly associated with specific roof types. For instance, Victorian or Colonial-style houses often have pitched roofs, while modernist or industrial-style buildings may feature flat roofs. Familiarize yourself with different architectural styles to help identify the likely roof type.
Seek online resources: If you have the address or a picture of the house, you can try searching online using real estate listings or mapping tools like Google Maps. Sometimes, aerial or satellite imagery can provide a clear view of the roof, allowing you to determine the type.
Remember, these methods are not foolproof, and there can be exceptions. To obtain the most accurate information, it is always advisable to consult a professional or physically examine the property.
