While it’s not required for property owners to understand all the technical aspects of a roof, it still pays to learn some jargon commonly used in this subject. This can come in handy when it comes to making decisions should the time come that you start to plan for a new construction project or you need to have your existing roof replaced.
You may have already heard about water-resistant and water-shedding roofs, but how do they differ from one another? Kroll Construction, one of the leading roofing companies in the area, discusses further:
Water-resistant roofs, also known as hydrostatic roofs, have a low pitch to manage slow-moving water. They feature a slope of less than 3:12.
Unlike water-shedding roofs, they don’t require a secondary membrane to keep water from entering your property. However, waterproofing may be necessary because it’s vulnerable to standing water. Your roofing company should take a few extra steps to make sure the roof is watertight, especially if your roof has several architectural elements like gables and valleys.
On the other hand, water-shedding or hydrokinetic roofs have a high slope so water can quickly flow into the gutters. They have at least a 3:12 slope or higher. The steeper the roof, the more effective it is at driving water away from its surface. Most residential roofs have a 4:12 to 9:12 slope.
Since water-shedding roofs are not waterproof, they need a secondary membrane to keep water from entering your home or building. They also require proper ventilation and insulation to avoid problems caused by condensation.
