Understanding the key components of a complete asphalt shingle roofing system can help you make sound decisions about roof repairs and replacements. It will also give you an idea about which home improvement contractor deserves your business.
There are at least six major components that make up your roof. Here they are:
1. Asphalt Shingles
The most obvious part of your roofing system is the top, where asphalt shingles are located. They provide protection against the elements, and they also play an important role in the look of your home. Shingles are the first line of defense against sun, rain, snow, hail, debris and others that might threaten your home’s safety, security and comfort.
The underlayment is a waterproof or water-resistant material installed on your roof deck. This sheet sits between your shingles and wood deck, providing the second line of defense against water penetration. During severe weather events, if your roof loses shingles, your home will still stay protected against rain as long as the underlayment holds. During a roof replacement, your provider of residential roofing services will assure you that even if it rains a little. As long as the underlayment is already installed, you won’t have to worry that they’re still installing the shingles.
3. Water and Ice Barriers
Your roof has some parts that are more vulnerable to water intrusion than others. Valleys, penetrations and protrusions are such parts. Valleys are where slopes meet. Penetrations and protrusions include skylights and chimneys. To keep water and ice out, your roof is equipped with barriers made of polymer-modified bitumen. Barriers bond to the roof deck to maintain waterproofing.
4. Starter Strips
These products are critical for shingle installation. They provide the sealant to keep shingles on your roof during windy conditions and to add to its waterproofing.
5. Hip and Ridge Products
Hip and ridge products are added to the shingles for that complete aesthetic. They also add to the waterproofing capabilities of your roof.
Ventilation is important in making sure your roof functions at its best. Without ventilation systems, roofs are less effective in keeping a home protected, comfortable and energy-efficient. The ventilation system of your attic allows moisture and heat to leave, helping your roof avoid ice dam formation and premature shingle deterioration. Ventilation systems should keep the attic temperature as close as possible to the outdoor temperature.
These six components, along with other minor ones, complete your asphalt shingle roof. They provide redundancy and durability for a reason, and that is to protect your home from the elements for as long as possible. They also contribute to your home’s aesthetics and energy efficiency.
