When is the best time to make aesthetic changes involving the roof (i.e. pitch, skylights, vents etc.)?
Changing a flat to a pitch roof is a good idea and alleviates problems associated with flat roofs. This would entail installing a new roofing structure. Skylights can be installed at the time of a new roof or during repair work. It is typically a good time to install vents when a new roof is being installed. More ventilation can also be added at any time to help better ventilate the attic for better protection against ice dams and to obtain a longer life expectancy from the roofing structure.
