3 Common Mistakes With Roof Flashing Repair

A common roof repair is the repair or replacement of roof flashing.  Roof flashing is the sheet of metal that is installed on the joints or edges to prevent leaks. Roof flashing is typically made with aluminum or galvanized metal so they are relatively cheap to replace. If you have experience with roofs, you can easily do this job yourself.  Here are three common mistakes to avoid.

1. Doing Nothing – When it comes to your roof, you’ll want to get leaks repaired as quickly as possible. If you put it off, it could lead to even bigger problems down the road. Water leaks can cause mold, mildew & rotted wood that can be a home owner’s nightmare. Get your roof fixed as soon as possible!

2. Being Careless – When you’re on a roof that is 20+ feet above the ground, safety is of the utmost importance. Use a safety harness or spotter to avoid falls. Also, wait for good weather before you start climbing on your roof.  The last thing you want is to be on the roof when a thunderstorm rolls in.  Wet roofs can be very slippery.

3. Being Sloppy – You’ll want to get leaks in your roof fixed as soon as possible but there is no need to be sloppy with the repairs.  Take your time with the job and make sure you do a good job.

There are 3 different types of roof flashing repair. Step flashing is when you repair the damage by putting in new flashing over the damaged area. First, snip the new flashing with your shearers, then bend it to a 90-degree angle. Then slide it up the roof, preferably on top of the damaged flashing. Adhere it using your flashing cement.

Vent Flashing is damage near or on the vents of your roof. First, locate the leak. If the problem is with the pipe itself, you should replace it with a new collar or install a larger collar over the existing pipe. For more severe damage, you may need to install all new vent flashing, which requires removing the shingles and replacing each piece again. Your roofing nails will be used up quickly if this is the case. Make sure you have enough.

Chimney flashing involve repairs done around the chimney area. If the damage and the leak are minor, you should be able to replace the chimney flashing just like you would step flashing. If the mortar joint is deteriorating, the joint will need to be repointed and you may need to have this done professionally. Either way, the damaged area will need to be cleaned with steel wool or the flashing cement will need to be used to finish the job.
