A Guide on Combo Roof Waterproofing

A Guide on Combo Roof Waterproofing

Hydrostatic and Hydrokinetic roofing systems are two types of combo roof waterproofing systems. They are both excellent options and are often used for the same purpose. In this article, we will go over the benefits and drawbacks of each. You’ll also learn how to choose the best option for your roof. Once you know the basics, you’ll decide with confidence. Read on to learn more if you’re ready to invest in a new roof for your home.


The technical term for home exterior waterproofing is hydrostatic pressure. It’s an essential element of the design stage and is the basis for choosing a waterproofing and dampproofing system. But what is hydrostatic pressure, exactly? Here are a few key elements to consider when choosing a waterproofing and dampproofing system. And don’t forget to consult a professional. Hydrostatic pressure is a form of pressure that comes from the Earth and can be transferred to a building’s exterior through pressures applied to it.

One of the most common forms of hydrostatic roof waterproofing is the hydrostatic panel. The seams of hydrostatic panels are anchored to the structure with mechanical fasteners. Manufacturer-approved sealant protects against water infiltration. A hydrostatic roof is perfect for gently-sloping roofs because rainwater flows more slowly. Furthermore, certain hydrostatic roofs don’t require underlayment. Contact a hydrostatic roofing contractor today to learn more about this type of roof.


Hydrokinetic roof waterproofing will prevent water from penetrating your home when installed correctly. This type of waterproofing uses gravity to shed rainwater. Because they rely on a secondary membrane to keep water out, they are best suited for steeply sloped roofs. They also have the advantage of being easier to install, as some models feature snap-on components. However, these roofs do require an underlayment beneath them and should only be used where you are certain of the slope of your roof.

While the International Building Code does not specify minimum slopes for metal panels, some manufacturers claim hydrokinetic tile systems can be used on a very low slope. Some manufacturers tout systems suitable for slopes as low as 2 percent. However, the National Roofing Association (NRCA) recommends a minimum slope of at least 1/2 inch per square foot of hydrokinetic roof assemblies and 3 inches for hydrostatic systems. The greater the slope, the better the leakage protection.
