There are different designs of roofs, and they come with varying designs of installation. Most shelters have two sloppy sides, except flat roofs. The sloppy sides meet at the center or on the sides, and covering the meeting prevents water and ice leakage.
A ridge cap covers the space on the roofs’ meeting points, which also ensures the correct temperatures of the house remain. As a result, this reduces the work of the HVAC system, saving a lot on energy, hence energy efficiency.
The roof ridge helps to maintain the house’s structure. It blocks rainwater and snow from entering the house, which affects some structures like wooden roofs. Wood will suck in water and rot, reducing its lifespan.
Rainwater entering the house through the roof could also cause weakening on the walls. Cement gets too cold and becomes a favorable environment of mildew. Mold causes allergic problems to homeowners.
Ridge caps seal the roof entirely to ensure insects and small animals do not enter the home. This is essential because these animals enter into the HVAC system and reduce its efficiency. They can also bite and spread diseases to children.

- Put another sealant tape on the closure strips, leaving the paper backing in place.
