Roofing Shingles

Roofing Shingles are one of the components that many of us are already familiar with. One of the best types of shingles is the asphalt shingles. Relatively lightweight, inexpensive, and easy to install, asphalt shingles are the best choice for most houses. They come in sheets that are layered on a roof to give the illusion of more expensive single shingles, such as cedar and slate, these are installed one shingle at a time. The cost of building materials is rising pre covid, so the cost of shingles may be some what pricey during all the changes that have came with the pandemic. Out of all shingles, IKO are the weakest and are the most prone to damage and wear in tear. Wind storms can easily cause serious damage to their shingles that require emergency repairs. Most roof repairs are done because of the IKO Shingles.


There are many different types of roofing underlayment types. There are three basic types of underlayment used beneath roofing materials: asphalt-saturated felt; rubberized asphalt; and non-bitumen synthetic.  The best underlayment for a roof is currently the choice of synthetic roof underlayment, and with good reason. Made with an asphalt-saturated basement and fortified with a mix of fiberglass, this product is not only extremely water-resistant, much stronger and more resistant to tears than other types of underlayment. Underlayment’s are designed for use on residential roof decks as a water-resistant layer beneath roofing shingles. CertainTeed manufactures the utility grade felt underlayment’s ShingleFelt® 30.

Proper Attic Ventilation

Proper attic ventilation systems allow a continuous flow of outside air through the attic which creates cooler attics in the summer and drier attics in the winter. It consists of a balanced system between air intake (at your eaves or soffits) and air exhaust (at or near your roof ridge). CertainTeed offers Ridge Vent, Rolled Ridge Vent, Static Vents, and Intake Vent products to meet a variety of ventilation needs. A metal roof typically does not increase nor decrease the need for ventilation. Ventilation that meets code requirements is adequate for any type of roofing material, including metal. Ridge vents are the most popular option for metal roofs and are an effective way to achieve proper attic ventilation. Ridge vents are installed at the ridgeline of the roof and run continuously along the entire span of the roof. The Razorback Ridge Vent is installed along the bottom of the ridge cap on either side.
