How to Install Roll Roofing Over Shingles
If you’re wondering how to install roll roofing over shingles, there are several ways to go about it. Here’s a quick guide to the process.

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. Before you start the installation, measure the roof to ensure the right length and width. To measure the length, multiply the width by three and then divide by two. Once you have the length, cut the roll roofing to the length and width.
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. Use nails every three inches and place them about one inch from the edge of the roof. Roofing cement should be applied near the edges of the roll roofing. You can also add boot flashing. To attach the roll roofing to the roof, follow these simple steps:
The first step to install roll roofing over shingles is to clean the roof before installing it. Use a broom to clear off any debris from the roof, including loose nails and mud. Once this is done, you can apply primer to the entire roof with a paint roller or sprayer. Make sure to have a temperature of at least 45 degrees before applying the primer. You’ll need to stay below the chalk line to prevent your roofing from lifting or coming loose.
Another step to install roll roofing is to lay down a layer of roofing felt underneath the shingles. 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!
The next step is to nail down the first layer of roll roofing. Remember to measure each part of the roof. Make sure that the eaves are level, as they may not be exactly the same height across the entire 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.
While laying roll roofing over shingles doesn’t require any special tools, you should take some time to learn about the material and its benefits and disadvantages before making a decision. Roll roofing is an asphalt-based mineral-surfaced material that comes in rolls of 100 square feet and weighs about 75 pounds. It can be purchased at any home improvement store. Although rolled roofing is comparable to asphalt shingles, it is less durable and lighter.
