Leaking Back Porch: How Can A Rubber Roof Protect It?

Articles

If your back porch leaks water whenever it rains, install a rubber roof over it. Although your back porch is an extension of your home, it can develop holes in the roof and leak water into the room if you have the wrong roofing material installed on it or if the weather conditions in your area are too hot, humid or wet. The porch can also develop problems, such as rot and mold, in the foundation, wooden posts and other areas that add to the problem. If you don't take steps to protect your back porch now, the water can eventually damage the rooms connected to it. Here's what rubber roofing is and tips you can use to secure and protect your back porch from rain.

What's Rubber Roofing?

Roofing contractors generally install rubber roofs to repair and reinforce homes with damaged or compromised flat roofs. The material forms a strong, protective barrier over an existing roof, or contractors can use the material to replace the entire roof. Before you install a rubber roof over your back porch, consider a few things first, including the type of weather conditions in your area.

Sometimes, roofing materials get damaged and leak when you expose them to hot and humid conditions. For example, if your city or state experiences heavy thunderstorms in the afternoon with intense heat waves but cooler weather later on during the evening and night, your back porch's current roof can build up heat and moisture over time. The heat and moisture eventually create a roofing phenomena called blistering.

Blistering develops when large amounts of moisture form on the surfaces of your porch's roof. The moisture heats up when the outdoor temperatures rise, which eventually pushes up the roof's underlayment and shingles until they form large bubbles or blisters. If the blisters rise too high, they pop open, which allows rainwater to penetrate the back porch's wooden foundation, posts and flooring.

One of the best things about rubber roofing is its ability to keep moisture from seeping beneath it and forming blisters. The roofing material used for rubber roofs contain elastic compounds that allow it to resist heat, repel moisture and protect against wear and tear. The material not only covers the roof like a second skin, it also adheres to it like glue to seal in or cover imperfections, openings and other structural issues.

For example, if your back porch has a wooden frame made with widely-spaced slats, a rubber roof benefits you, because it forms a seal over each individual slat. If rainwater can't penetrate the slats, it can't puddle or pool between them and attract heat.

If you're ready to repair your leaking back porch roof, contact a roofing contractor to get started. In the meantime, you need to protect and reinforce the rest of the porch against rain damage.

How Can You Strengthen and Protect the Wooden Posts of Your Back Porch?

If you don't reinforce the wooden posts on your back porch, you'll still experience problems from rainwater and moisture. One of the things you want to do is remove and replace any wooden posts that contain rot, mold or holes. These posts won't support your new rubber roof properly after installation, especially if rot or mold spreads to the foundation beneath the roof. 

It's a great idea that you varnish or seal the posts with a water-proof solution or paint after you replace or repair them. However, always choose a varnish or seal that works best for the type of wood on your porch. For instance, if you have cedar wooden posts supporting your porch, choose clear lacquer to keep water from damaging the wood and changing its natural beauty and color.
