Repair Leaks In Your Roof With Spray Roofing Sealant

If you have a leak in your roof, instead of just replacing the damaged tiles, seal up the area where the leak was with spray roofing sealant. This will ensure that the leak is properly sealed and will not reoccur.

Identify Where The Leak Is

The first thing you need to do is get up on your roof and figure out where your roof is leaking, or where the flashing or shingles are peeling away and causing a condition suitable for leaks to develop.

Replace Missing Shingles

If any shingles are missing, you'll want to purchase new shingles from your local home improvement store. You'll need some thin nails as well to hammer the shingles into place.

Once you've purchased the shingles, take them up to your roof along with some nails and a hammer, and hammer them into place. It should only take you about a minute or so to replace each shingle; the length of the project depends upon how many shingles you have to replace.

Clean Any Debris Off Your Roof

Once you have replaced the shingles, you need to clean any debris off your roof. You don't want to spray the roof sealant on top of the debris; if you do this, the debris will permanently be adhered to your home.

You can use a broom to gently sweep debris off your roof, or you can use a pressure washer to remove any debris from your roof.

Rough Up The Area

Next, you will need to rough up the area where you want to spray the roof sealant. You can do this with a little bit of sandpaper. Just take the sandpaper to the area where you want the roof sealant to go and work over the shingles a little bit. You need the shingles to be a little rough so the sealant will stick to them. 

Spray The Sealant

Finally, you are ready to spray the sealant. Make sure that you are wearing safety goggles as well as safety gloves and a long sleeved shirt to protect yourself from the sealant.

You will need to shake up the can of roof sealant that you purchased in order to activate the ingredients. Then you will want to hold the can back about a foot and a half from the area you want to spray. When you are ready, spray back and forth across the affected area, and work your way from the top to the bottom of the area.

You will want to apply between three to four light layers of roof sealant to the damaged area. You should spray a couple of inches past the area where you roof leaked previously in order to ensure that the area is properly covered.

Let the sealant dry, then test out the area by pouring a small amount of water over it. The water should no longer leak through and should just roll off. This project, if done all at once, will take about a day to complete. For more information, talk to a local roofing contractor (such as Bell Roof Co).
