 Other Factors Will Affect the Price of  Your Houston Residential Roofing.


Roof Pitch and Slope

Strong Metal RoofRoof pitch can dramatically affect installation and repair. In fact, the slope or pitch of a roof can determine the kind of roofing material you use. Slope and pitch are two terms often used interchangeably, but they actually mean different things. The slope is described in inches of vertical rise per foot of horizontal run. For example, a gently sloped roof that rises 4 inches for every 12 inches of house covering is said to have a 4 in 12 slope. Pitch is expressed as a fraction – the ration of rise to the total span of the entire roof. The same gentle 4 in 12 slope translates into a 1:6 pitch. Completely confused? Don’t sweat.

Water Diverters:

Similar to gutters, a water diverter is a piece of metal that helps to control the flow of water as it drains from the roof.

Heat tape:

This is an electrical feature that heats gutters during the winter and keeps water flowing.  Probably not needed in the Houston area.


After your roof sheds any water from the house, the gutters and downspouts act as a drainage system for your roof.
