While you may think that replacing or repairing a few shingles on your roof is a DIY job, you may want to reconsider. Roof repairs can be complicated, and in the hands of an amateur, bigger problems can arise. Here are some common mistakes made when trying to DIY shingle repair and why it’s best to call a professional roofing contractor.

5 DIY Shingle Repair Errors

1. New Over Old

Many amateurs who attempt to repair roofing themselves will lay new shingles over the old, damaged ones. This doesn’t solve any issues lurking underneath the compromised area. If you noticed a leak, the source might not be at that spot, and simply patching the area will only allow the leak to get worse. There may also be issues with the decking that only a roofing contractor can identify once old shingles are removed.

2. Warranties

Roof repairs should be based on the specifications laid out by the manufacturer of the materials. Working with tools and components that you aren’t familiar with can lead to misunderstanding instructions and inadvertently negating any warranties on materials. In some cases, the choice to not use a roofing contractor is enough to void your warranty.

3. Misalignment

Shingles must be perfectly lined up to ensure they protect your property. For the DIY roofer, the chances of misaligned shingles rise when you don’t know the right techniques or have the correct tools. Another issue that occurs is that shingles don’t remain flat, which makes your roofing vulnerable to water getting underneath and inside.

4. Old Materials

You may be tempted to use old or recycled materials to save on costs, but for some areas, this risks the integrity of your roof. One area in particular, the flashing, is critical for keeping moisture at bay. Many DIY-ers will try to reuse flashing in their roof repairs, leaving their home vulnerable to leaks.

5. Problems With Fastenings

Experts know the perfect size nails to use for your roofing. If you attempt to perform roof repairs yourself, you risk using hardware that is too short or too long, which will make the shingles less secure. When the fastenings are inadequate, a heavy wind or rainstorm will wreak havoc on your property, blowing off the weakened shingles and causing water to seep inside your home.
