Sloped Roofing

Sloped Roofing is categorized by the intensity of slope. The terms low-slope and steep-slope describe that slope. Slope is how much a roof slants.

A low-slope roof is one that has a slope of less than 3-in-12. This means that for every horizontal foot, the roof level goes up less than 3 inches vertically. A steep-slope roof (typically a shingle roof) depends upon gravity to cause water to flow in one general direction so it can “shed” the water over the breaks and fasteners in the shingles until it flows to the edge. A low-sloped roof or flat roof, can’t depend upon the water to flow in any particular direction so it must form a watertight, monolithic membrane that stays watertight all the way to the drains or edge. Modern low-slope roof roofs tend to use a continuous membrane covering which can better resist pools of standing water. These membranes are applied as continuous sheets that are bonded together with heat-welding or adhesives.


Client Testimonials

"I'd like to formally thank the Service Department at Greenwood Industries for their professionalism and dedication to their work.  From the first call we made to you as a new customer, I could tell you were dedicated to great service.  After that first call, your technician called to confirm his anticipated arrival time, and actually arrived on time!  All of the various roof leaks were satisfactorily repaired and you even called the next day to check on the performance of those repairs. As a Master Electrician who has worked in a service role for many years, and now as acting Facility Manager for one of the Commonwealth's most critical buildings, it was refreshing to see that same respect, values, and professional displayed by your techs that I remember from years past.  You just don't see this kind of customer service as often as we'd like anymore."
