How to Prevent Rain from Entering a Screened Porch

Quck answer

To keep rain out of a screened porch, you can take the following steps:

1. Install a rain diverter: A rain diverter is a device that helps redirect rainwater away from the porch. It can be installed on the roofline above the porch and diverts water away from the screened area.

2. Use weatherstripping: Apply weatherstripping to the doors and windows of the porch to create a tight seal. This will prevent rainwater from seeping through any gaps or cracks.

3. Install outdoor curtains or shades: Hanging outdoor curtains or shades can provide an additional layer of protection against rain. These can be closed during rainy weather to keep the porch dry.

4. Maintain the porch regularly: Regularly inspect the porch for any damage or wear and tear. Repair any holes or tears in the screens promptly to prevent rain from entering.

By following these steps, you can effectively keep rain out of your screened porch and enjoy a dry and comfortable space.


Screened-in porches offer a shaded and insect-free outdoor space. However, most screens are not strong enough to withstand severe weather conditions. After a rainstorm, your screened porch may become wet. Unless you plan to convert the screened structure into a solid, walled part of the house, it is impossible to keep every drop of rain out. However, you can minimize the amount of rain entering by weatherproofing the porch.

Step 1

One of the easiest and cost-effective ways to prevent a large amount of rain from entering your screened porch is by installing an extendable overhang. While intense rainstorms with strong winds may still penetrate this defense, an extendable overhang will keep out most vertical rain. The overhang should extend several feet beyond the regular roof of the porch, providing a protective buffer zone. Expensive models require professional installation and hand cranks, but you can create a quick do-it-yourself overhang by attaching a tarp to the existing ceiling and securing it with sturdy poles. When you want to remove the temporary overhang, simply untie the tarp from the poles, roll it up, and tie it near the roof using affordable ropes.

Step 2

Consider using storm windows for your screened-in porch. Similar to regular house windows that have screens for ventilation, you can cover screened-porch windows with attachable glass to protect against harsh weather conditions. These windows can be attached to the screened-porch windows using small locking clips. While this option may be more expensive, it provides excellent rain protection. Although screened-porch storm windows are not as durable or leak-free as regular house windows, they offer one of the best protection options available.

Step 3

Install a drainage system on the porch floor. While this will not completely prevent rain from entering, it will help prevent or minimize water damage. Water is one of the main causes of discoloration and seasonal wear on a wooden or concrete porch floor. If you have a wooden porch, installing a drain is relatively simple and affordable. You can cut a hole in the floor using a jigsaw, place a decorative drain cover, and run a gutter underneath the hole to redirect water outside the porch instead of underneath it. For a porch with a concrete base, it is recommended to consult a professional contractor for installation.
