Solved! What To Do About a Leaky Roof

8/31/2016 (Permalink)

Q: Help! I woke after last night’s storm to find a discoloration on the kitchen ceiling and a puddle beneath. What do I do about this new leak?

A: There’s nothing quite like an indoor puddle to put a damper on your rise-and-shine routine, is there? The first thing to do is mitigate any moisture damage. That can get complicated, since a leaky roof doesn’t always appear as a puddle on the floor (or at least not immediately). Occasionally, the only sign of a leak is that subtle discolored patch on your ceiling or wall, caused from water pooling behind it. When you’re lucky enough to spot it early on, intervene as soon as possible following these steps.

Secure the scene. If water has only dripped onto the floor, consider yourself lucky and move a bucket to catch the falling droplets. (While you’re at it, save your sanity by propping up some scrap wood inside the container to mute the annoying drip-drip-drip sound.) Otherwise, move as much out of the water’s path and cover items that are too heavy to relocate with thick plastic sheeting.

Drain the water. Using a ladder or a sturdy chair, climb up and puncture the water-damaged patch with a screwdriver. Making a hole might sound counterintuitive, but skipping this step will allow more moisture to seep in. The weight of the water might even cause your ceiling to sag or collapse—one more thing to add to your list of necessary repairs. Ultimately, patching up a small, 1/2-inch drainage hole is a lot easier and cheaper than dealing with structural damage.

Start sleuthing. So where’s the source of that pesky leak? Water travels down trusses or flashing until it finds a weak spot, so the entry point into the house isn’t necessarily directly underneath the part of the roof you’ll have to fix.  If you have attic access, head up there first during daylight hours. Turn off the lights and look up for any small opening that allows sunshine to stream through—an obvious source for your leaky roof.

Fight water with water. Can’t spot any signs of damage from the attic? Your next step is the water-test method, where someone stands outside on the roof and, using a lengthy hose, showers the roof until the drip returns—giving you a second chance to locate the source.

Phone a professional. Sometimes, finding what is in need of repair is not as easy as spotting a hole in your attic’s ceiling. From failing flashing to clogged gutters to crumbling shingles, the list of potential causes is very long. If you’ve conducted a thorough inspection and you’re still not certain what has led to your leaky roof, it’s time to call in a pro to both deduce the problem and recommend a fix. The actual repair will depend on many factors, including shingle type and pitch.

Meanwhile, lay out a tarp. When you’ve determined the source of the leak but can’t get a same-day repair, you’ll have to find temporary measures to protect your roof and home from snow, rain, and more water damage. If the roof is dry enough for you to carefully climb, try covering the affected area with heavy plastic sheeting or a tarp (at least 6 millimeters thick) and some 2×4s. Start at least 4 feet beneath the problem area and slowly roll the plastic over it, past the the ridge of the roof, and 4 feet down the opposite side to cover your leaky roof completely. Place one 2×4 at the “top” of the tarp (the opposite side of roof) and one at the bottom to weight it down, folding the tarp back over each plank and fastening it to the wood with a staple gun. The bottom board should rest in an eave or flat area against the roof. Lay a third 2×4 on the top board (which is wrapped in plastic sheeting) and secure it to the wrapped board with nails to help anchor the covering. Use more 2×4s resting on the plastic’s perimeter if you’re worried about wind.

While you work outside, remember: Proceed carefully and—unless you want to compound the problem with a few more leaks—do not puncture your roof by nailing or screwing boards directly to it.
