Shingling a roof ridge is perhaps the most difficult and easiest project to finish off a roof project. The roof ridge is the uppermost portion of the roof where the shingles are laid a little bit differently. The difficulty lies in getting it just right to keep any type of water from leaking through and damaging the roofing materials. However, do-it-yourself homeowners can shingle their roof ridge with a few simple steps for saving money that would have been spent on contractors. 

Step 1 - Prepare Shingles

Collect the number of shingles that will be needed for the roof ridge. You should lay them in stacks near the ridge so you will not have to be going up and down the ladder several times. This not only saves you a lot of time, but also lessens the potential for injury. 

Step 2 - Cut Shingles

You need to take some time to further prepare the shingles for the roof ridge by cutting off the tabs on the end of them. Use a framing square and a utility knife to cut off each individual tab. Leave 2 to 3 inches of the tab so that you will be able to use them as a way to seal the roof ridge with roof cement. The corners of each tab should also be cut at a slight angle to prevent water building up. 

Step 3 - Wrap Shingle over Ridge

Start with a few shingles anywhere on the roof and warp them around the roof ridge. This will tell you if you need to add another row of shingles to the top part of the roof or not. Once the shingles are wrapped around the ridge there should be at least 4 inches of overlap. 

Step 4 - Snap Chalk Line

Snap a chalk line across the top portion of the last row of shingles. This should be 4 inches from the top edge. 

Step 5 - Install Roof Ridge Shingles

Start at one of the eaves of the ridge and wrap a shingle around the ridge of the roof. Line up the edges with the chalk line and secure with 2 roof nails right above the adhesive line on the shingle tab. The shingle should be in the center of the ridge. Continue along the ridge of the roof until you have all of the shingles secured. Overlap the last shingle as much as needed to get a perfect fit along the edge.

Step 6 - Seal Ridge Roof Shingles

Once the last shingle is placed on the roof ridge of your building you will need to seal it to protect it from the weather elements. Use some roofing cement for this part. You can use a scraper to spread the cement out of a can or use a caulking gun and tube. Lay a strong bead of caulking, or spread a thick amount of cement along the edge of the roof ridge shingles. Make sure that there are not air bubbles or holes in the caulking that will allow water to seep through to the underlying roofing materials.
