Malarkey shingles are designed and engineered to beautify and protect a home. As part of the roof system, the shingles and underlayment limit the impacts of weather and exterior elements on the structure. Much like wearing a waterproof jacket, shingles and underlayment act as a protective membrane, but require ventilation from heat and moisture beneath. Without proper ventilation, many problems can arise, including a reduction in service life from the shingles themselves, according to Dr. Joseph Lstiburek of the Building Science Corporation.
Whether your current roof needs replacing or you’re in the midst of a new construction, roof installation is a huge investment and needs to be handled properly. Even though you know it’s one of the most important features of your home, you may still have a few jitters about the size of the project, or worry that you may not be making the right decisions. Let’s take a closer look at the installation process.
Underlayments are installed between the roof deck and the shingle to provide protection to the deck during installation as well as act as a secondary barrier from leaks and ice dams after installation. Let’s look at the different underlayments offered by Malarkey.
