Repairing Leaky Roofs: DIY Solutions

A leaking roof can cause serious problems, such as mold and rotting framing and sheathing. Taking some simple steps can prevent this and limit the damage.

First, find out where the leak is coming from. Climb into your attic and use a flashlight to scan the area. Look for signs of water stains, dark mold or rot on the rafters and wall plates.

1. Tarp the Area

After finding the source of the leak, it is important to minimize the damage until you can arrange for a professional repair. One simple way to do this is to tarp the area. This will protect the roof from further moisture damage and prevent water from seeping into the interior of your home.

Using a ladder, unroll a tarp large enough to cover the damaged area plus at least three feet on each side. It is best to use a tarp that is thick and has UV inhibitors to help it last longer. For a more permanent fix, you can create anchor boards from wood and nail the tarp to them. This will ensure that the tarp stays taut and isn’t prone to collecting rainwater, snow or debris underneath it.

Once the tarp is in place, you can add a layer of waterproof sealant to the top of it for added protection and prevent water from being able to penetrate through the tarp into your home. This will also extend the life of the tarp and reduce the risk of it falling from the roof during windy weather.

If you are concerned about the stability of your tarp during severe weather, you can sandwich it between two 2×4 wooden planks and secure it to each. This will help to ensure that the tarp does not flex or fly away during storms, which can cause further damage to the shingles and roof decking underneath.

For a temporary solution, you can also use sandbags to weigh down the tarp and keep it in place during severe storms. Just make sure that the sandbags are placed so that their narrow ends are either up or down over the roof ridge, depending on the direction of the leak.

You can also use a product to temporarily stop leaks in a small area. This isn’t as strong or permanent as a tarp or roof cement, but it will provide a quick and easy temporary fix.

2. Replace Shingles

Although asphalt shingle roofs are designed to last for years, they do deteriorate over time. Leaks usually develop in areas where shingles meet other materials such as flashing, vents and dormers. Water can also leak through cracks in a shingle or where the edges of a shingle curl under, called a granule loss.

If your roof is showing signs of leaks, a quick fix is to replace the damaged shingle or shingles. If you have the right kind of roof, this is a relatively easy DIY project that can be done from inside your attic.

The first step is to locate the source of the leak. This may require some detective work to track down the location of water stains on your ceiling or a sagging section of the roof. Once you know where the leak is occurring, look for a gap or discolored felt paper on the underside of the leaking shingle. Also, check for rotted or moldy wood directly below or around the leaking area.

It’s important to inspect the surrounding shingles, too, since the leak could be caused by other problems, such as loose or missing shingles, or improper flashing. These Springfield MA roofers can help you determine the severity of the leak and suggest any additional repairs that might be necessary to prevent further damage.

If you’re unsure where the leak is coming from, it may be possible to track it down with a garden hose. Get someone to stand under the leaking spot while you run the hose uphill. Water will seep through any gaps or cracks, making it easier to identify the source of the leak.

Once you have identified the problem area, it’s a good idea to have replacement shingles on hand. If the shingles are not severely damaged, you can simply apply shingle cement to the edges of the new shingles and nail them in place. It’s best to do this on a warm day so the cement will bond more easily. Otherwise, the cement will remain gooey and difficult to shear away with a pry bar.

3. Replace Flashing

A leaking roof can cause a host of problems including water stains, mold, rotted framing and sheathing, damaged insulation and ceiling damage. If the problem isn’t addressed quickly, it can lead to more extensive and costly repairs. In many cases, a homeowner can perform simple roofing repairs to stop the leaks and prevent further damage until they can afford to have the roof replaced.

The first step is to identify the source of the leak. If you have access to the attic, head up there with a flashlight and look for signs of mold or mildew. Examine the area closely and look for places where water has collected or for puddles that indicate a blocked drainage path. It’s also a good time to assess the overall health of your roof. Look for cracks, dents, tears, and missing shingles.

Leaks are often caused by damaged flashing, which is installed around chimneys, dormers, vent pipes and valleys where different roof pitches meet. It is also used to seal the edges of a skylight or other penetrations in the roof. The flashing is made of copper, galvanized steel or aluminum and is installed over the joints in the roof sheathing and rafters. When the flashing is damaged, it can allow water to seep into the home and cause damage to drywall, molding, furniture and other interior elements.

You can repair most flashing problems with roof sealant, but if you need to replace the flashing, it’s a job that should be done by a professional. In addition to replacing the metal sheeting, you will need to remove the shingle covering and sheathing at the leaky spot to install the new flashing and apply a protective coating.

It’s best to get started on a roofing repair project during dry weather, but if you must work in wet conditions, make sure you have a pair of rubber-soled shoes and use a long ladder. It’s also a good idea to bring a helper so that you can both work safely from the ground and on the roof. It is important to prioritize safety and always follow the manufacturer’s instructions for the roofing materials you are using.

4. Puncture the Bulge

A big leak may cause a sagging bulge in your ceiling that you can spot by looking for water spots. While it might seem counterintuitive, puncturing this bulge with a screwdriver will allow the water to flow down rather than pooling in that area and damaging the rest of your ceiling. It will also prevent the bulge from growing larger and eventually bursting on its own, which would require even more water to be evacuated.

Once you’ve spotted the bulge, get some roofing tar from your local hardware store (or just use any durable material that will hold up until you can replace it). Apply the tar to the bottom of the spot and around it. Then, place a bucket or other container underneath the spot and puncture the bulge at its lowest point to let the water drain out of there. Then, be sure to check the bucket frequently and empty it if necessary.

Another roof leak repair trick involves slipping a strip of adhesive ice-and-water barrier (available where roofing repair products are sold) under the shingle near the soffit and main roof joint. This will help prevent leaking in the future, especially if you can’t improve your attic insulation or increase ventilation to reduce heat buildup.

If you can’t tarp your entire roof, try to cover the area where you think the leak is coming from with as much plastic sheeting as possible. Use wooden planks (2x4s are good) to hold the covering in place, and make sure it extends all the way up to the peak of your roof. If you don’t have enough sheeting, consider buying extra rolls of plastic at your local hardware store, and simply extending the tarp over the problem areas.

To help keep the tarps in place and minimize water damage, you might want to invest in some roof funnels that can be placed over the holes where the leak is occurring. These can be attached to the wide end of a hose, and then connected to the outlet on a window or door to help guide water safely out of the house.
