The roof is a section of your property that requires a high level of maintenance. Once it starts to leak, the roof can be fixed from the inside or from the outside. Keep in mind that these methods are considered workarounds. The only permanent solution to a leaking roof is a professional repair or replacement.
However, depending on the age of your roof and the general condition, this can help you save some time. Spread the roofing tar over the hole with a spatula, making sure to completely cover the opening. Place the small piece of plywood on top of the tar and then spread additional tar over the patch to keep it in place. If you're looking for a good ladder to climb to the roof, watch this Stuff We Love video on the Little Giant 22-foot ladder, which is available on Amazon.
In case there is no access to an attic, or you cannot find out the source of the leak, you can cover it with the plastic roof covering. It goes without saying that safety comes first and that if there is lightning, you don't have the capacity or the right equipment to do it; you should ask for an emergency roof repair. A tree branch breaks and impales your new roof, lightning strikes, or rogue hail breaks through a weak spot. Climb the ladder with an observer to help you and always be careful to move slowly and tread carefully on the ceiling.
Heavy rains can quickly and easily transform a once-small leak into an attic flood, allowing water to seep through the roofs and walls to the foundations of your home. Hang the planked end of the roof deck from the ridges of your roof and place the plastic over the eaves below. Learning how to repair a leaking roof from the inside allows homeowners to quickly suspend leaks that can cause water damage while investigating and addressing the source of the leak. Once you are there, thoroughly check the roof to see if you can identify any points where the leak may be entering.
In the event of heavy rain, as a temporary solution to roof leaks, you can repair your roof by replacing it from the inside and later you can repair it from the outside. But if you really imagine yourself as a DIY expert and have rubber-soled shoes, a saw to cut the 2×4, a ladder and some confidence to jump onto your roof, grab your deck and place a pair of 2×4 over the ridge and then stretch the rest to go down to the eaves. Dry standing water or puddles with sponges and towels, and then place a bucket under the drain to collect dripping water. Make sure you get enough 4-foot rolls to go around the entire eave of your roof where the leak enters, or the entire house if you can't locate it at all.
