Replacing a roof can be expensive, but spending a little more and having a professional who knows the ins and outs of all roofing components is worth the investment. Some roofers simply place new shingles over the tops of old shingles. While this may be less expensive in the short term, it is not good practice and could end up causing problems later down the road. There are many different parts that work together to make up a roof, and each individual piece has a very important job to do.
What parts make up a roof?
When many homeowners think of a roof, they think shingles, but it takes a lot more than just shingles to protect your home from weather, varying temperatures, and humidity. It takes an integrated system of many layers working together to keep a home protected and its inhabitants comfortable.
- Intake Ventilation: Intake ventilation products help replace warm, humid air with cool, dry air in the attic. Keeping a continuous flow of cool air prevents damage to the interior components of your roofing system. Without adequate ventilation, your home is more likely to build up moisture, leading to mold, mildew, and rotting. Poor roof ventilation can also cause ice damming and premature shingle deterioration. A good ventilation system alleviates these problems by keeping the attic temperature closer to the outside temperature.
- Ice & Water Barrier: This barrier is added to protect the roof in areas where water tends to flow and collect, such as in and around chimneys, skylights, and vents. It also helps prevent ice damming, which occurs when water melts and then refreezes, migrating beneath the shingles and hastening a roof’s deterioration.
- Underlayment: This additional layer of protection for your roof is placed between the wood decking and the shingles. It is primarily used to protect against heavy or wind-driven rains that could otherwise get under the shingles and cause damage.
- Starter Shingle Products: This is the first step to installing shingles properly. Starter shingles are placed down before the main shingles to provide the roof with a clean look. A seal is created between the starters and first row of shingles. This measure helps to prevent water infiltration and shingle blow-offs during high winds and heavy rains.
- Shingles: Shingles make up the outermost layer of the roof and are exposed to wind, rain, snow, ice, and whatever else Mother Nature has in store. They are tough in their defense against the elements and can add beauty to the home as well. Hedrick Construction offers duration and high performance shingles that last.
- Exhaust Ventilation: These products help pull out and remove hot, humid air from inside the attic, protecting the home from heat and moisture damage. Working with the intake ventilation system, it creates a continuous and balanced flow of air, removing humidity and drawing in cool, dry air.
- Hip & Ridge Shingles: These shingles are the final touches added to the roof to give it an attractive, finished look and additional protection.
As you can see, there is much to more roofing than just shingling. Selecting the right materials from the beginning can save you money, reducing many overhead costs, and increasing the life, efficiency, and performance of your roof.
