From Shingles to Rubber

How many different kinds of roofs can you spot on the houses on your street? A few decades ago, you may have only seen shingle roofs, perhaps with the occasional slate roof mixed in. But these days, there are more kinds of roofing on the market. Metal roofs are becoming common because they can be made from recycled materials. Tile is a popular choice because it lasts a lot longer than other roofing materials. And then there are some roofers who install rubber roofs because they're smooth and easy to install. Learn more about roofs of all types on this blog.

Roof Ventilation—How Its 2 Key Ingredients Prevent Roof Damage

Roofs are one of the most important tools a homeowner has to prevent unwanted debris, moisture, and cold from getting inside their home. But it's also important to know how to let the right elements in as well. This is where roof ventilation comes into play. Roof ventilation has two main components. Here's what they are and how they work together to keep your home safe and comfortable.

Intake

An intake vent is usually placed along the outer edges of the roof. It allows air to be pulled into the space under the roof. The natural movement of air allows warm air to rise through your home and get pushed upward toward the attic and roof. Many people note that their attics can often become the warmest part of their home. But this is more dangerous than simple discomfort in this often-neglected section of the house. Rising warm air warms up the decking and roofing above it. And if you live in an area where snow falls or ice forms, the warm air heats up the interior of the roof before the outer edges. Melting water flows to the eaves, which are cooler. That water may then refreeze and cause what are known as ice dams. The intake vents help cool off the attic by bringing in cooling breezes and reducing the overall temperature. 

Exhaust

Exhaust vents are the other end of the cooling equation. These vents provide an outlet for those breezes the intake vents bring in. The cooler air that flows in pushes the warm air out through exhaust vents. Most exhaust vents are designed to be ridge vents. Installed on the ridges where two sections of the roof meet, they are placed underneath shingles for a seamless appearance. However, you may also use other types of exhaust systems that work in a more controlled manner, such as small turbines, louvers, or powered exhaust vents. The right tools for your roof depend on your climate, weather, and roof style. 

Where to Learn More

Roof ventilation isn't something that most homeowners give much thought to. When done correctly, you may not even notice the vents or their effects.  However, when ventilation is lacking or insufficient, you'll notice the results, such as ice dams, uneven roof melting, hot attics, and condensation or moisture. 

The best place to begin protecting your home and your roof is by consulting with a roofing company, such as Bill's Roof Repair, Inc.
