Roof Repair

Some roof leaks you can fix yourself in an afternoon. Others will cost you far more if you try. The tricky part is knowing which is which, because DIY-ing the wrong one doesn’t just leave the problem unsolved, it can mean structural damage, a bigger repair bill, or a nasty fall from an unstable roof. In this guide, we’ll show you exactly what’s safe to tackle yourself, what isn’t, and how to do the DIY repairs properly when you do take them on. TL;DR First Steps When You Notice a Roof Leak Roof Leak Repairs You Can Do Yourself Now that you’ve found the source of the leak, you can fix it yourself if it’s caused by one of the common minor issues below.  1. Replacing Worn Roof Screws on Metal Roofs On metal roofs, one of the most common leak points is the roof screws. Each screw has a rubber washer underneath it that creates a waterproof seal. Over time, the rubber dries out, cracks, or flattens, allowing water to seep through the screw hole. How to replace a leaking roof screw 2. Replacing a Cracked Roof Tile If you have a tiled roof, even one cracked tile can let rain slip underneath and reach your ceiling.  How to replace a broken roof tile 3. Resealing Around Roof Pipes and Plumbing Vents Most roofs have pipes for plumbing or ventilation. Around these pipes is a rubber seal called a dektite or pipe boot that prevents water from entering. Over time, these rubber seals can crack, dry out, or pull away from the roof, allowing water in.

Cleaning and Re-Sealing a Whirlybird A whirlybird is a round, spinning roof vent that removes hot air from the roof space and improves ventilation.
