5 Foolproof Ways to Mend a Roof Leak

If you see water spots, sagging ceilings, or peeling paint anywhere in your home, they may be signs of a leak in your roof. Even the smallest leaks can result in catastrophic damage, including mold, decaying wood, and structural instability. Get ahead of potential disasters by addressing leaks as soon as you notice them. Here are five foolproof ways you can fix a leaky roof.

Replace Damaged Shingles

If the source of your leak is a broken or damaged shingle, replacing the shingle may solve the problem. To accomplish this, remove the damaged shingle by using the claw side of a hammer to pull any nails that are holding it in place. Then, use a pry bar to gently pry the shingle away from the structure. Once the old shingle has been cleared, slide a new shingle into place and attach it to the roof following manufacturer instructions.

Seal Joints

Cracks forming around joints, dormers, and chimneys are some of the most common sources of roof leaks. This can be fixed by resealing the cracks with caulk or roofing sealant. Before resealing, remove any old caulk, sealant, or rotten wood with a putty knife. Always consult a roofing contractor if you notice any extensive cracks, decay, or corrosion.

Replace Damaged Vent Boots

Vent boots can be plastic, metal, or both, and are found around the pipes on top of your roof, creating a seal between the pipe and the roof itself. A cracked boot, missing nails, or worn rubber seal can all result in unwanted leaks. Fortunately, a new vent boot can be purchased from most major hardware stores. If the boot is in good shape, you may only have to replace the missing nails.

Apply Coating to Entire Roof

A leaky, flat roof, such as a metal roof, can be repaired with a spray-on fluoropolymer coating, which is cost-effective and durable. Before applying any coating, make sure the substrate is as clean as possible to guarantee the best adhesion.

Patch with Roofing Cement

In an emergency, you can patch a leak with some roofing cement from a hardware store. Apply the cement to a dry roof for best results. For large leaks, stabilize the patch job by covering it with a section of roofing mesh.

Always make sure your roof is structurally sound before attempting repairs yourself. If your roof shows extensive visible damage or if the leaks persist, contact a professional contractor with the tools and expertise to complete the job safely and efficiently.
