If you’re unsure of the size of your roof, you can ask a friend to help you. Once you have the measurement, you’re ready to install the roll roofing.

To install roll roofing over shingles, lay down a strip that is 18 inches wide and set it into a bed of roofing cement. Roll it out across the length of the roof, overhanging the drip edges.

A layer of roofing felt protects against leaks and condensation, which is why it is important to lay down roofing felt before laying down roll roofing. Once you’ve mated the two layers, you’ll be ready to start the installation. As long as you’re confident in your carpentry skills, you’ll be on your way to an attractive roof!

After applying the cement, you can then add a second layer, which should be about 32 inches above the first layer. If you’re not comfortable using nails, you can also call local experts.
