How Often Do Roofs Need To Be Replaced

When it comes to knowing when it’s time to replace your roof, the most important factor is age. Asphalt shingle roofs usually last between 15 and 30 years depending on the environment and quality of installation. If your roof is older than 15 years, you should consider getting an inspection to determine if a replacement is necessary.

All our inspections are free. It is recommended to have your roof assessed after a large storm to check on any damaged shingles and make sure there is no further damage. Novalis also offers a large spectrum of repair work if you decide to go with a smaller fix.

If you experience any of these issues with your roof, call Novalis Roofing and Siding today – our experienced contractors can help get your roof back in its best condition!

Roofing: The Job Process

We arrive at the job site around 8:00 a.m. We begin each day by removing the old roofing from a particular section of the house. We remove sections and begin to install the new roof right away to minimize the amount of time your house is left vulnerable to the weather. We do not use dumpsters, as we own our own small disposal trucks. We always do our best to position these small trucks close to the area we are working so the debris can be thrown directly into the trucks and not to the ground avoiding costly damage to our customers landscaping. We will go as far as using plywood to protect the lawn and drive the trucks below the areas we are working.

After removing the old roof we then will replace any bad wood found, usually at an additional cost of our original proposal. In the picture you see a ¾ inch pine tongue and groove board used as the sub deck with small patches that needed to be replaced.

Other sub decks found are plywood.

Or a nailing rack found under old wood roofs. This requires new plywood to be nailed over the rack and metal edging to cover the edges of the plywood before the new roof can be installed.

Once the sub deck is cleaned down and all bad wood is replaced, we start by putting down the ice and water shield. This material is typically used on the gutter edges and in the valleys, required by building code.

If we feel an area is more vulnerable to ice damning, weather it is a north facing section, low pitched or an area where water/ice tend to build up as pictured here, we will use the ice and water shield more extensively throughout that area.

The next step is to install the synthetic underlayment throughout the balance of the roof surface. We use only synthetic underlayment products because they are stronger and lighter than traditional felts. They also provide a superior secondary water-shedding barrier over an extended period of time. In this case, we have used Owens Corning ProArmor Underlayment, one of the few breathable roofing underlayments’ on the market today.

After the underlayment and the Ice & Water shield are down we then begin installing the new roof. 

While installing the new roof, all vent pipes are flashed with new aluminum vent pipe flashings to size along with new step and counter chimney flashings. Our chimney flashings are a three step process. First, we install the roof around the chimney with step flashings.

The next step involves sealing the step flashings to the masonry using roofing cement.

And finally, the counter flashing is applied over the roofing cement and pinned to the masonry. The top edge is sealed with matching caulk to complete.

Once the new roof is complete, the gutters are cleaned out and tightened, the ground is thoroughly cleaned and a magnet search is done for all nails that may have fallen to the ground. All job debris is removed with all fees included in our proposals.

All of our new roofs come with a 50-year labor warranty from Novalis Roofing and Siding.

Proper airflow in a roof system is crucial for a healthy home. It prevents moisture buildup, heat accumulation, and damage to your roof. It is important for the attic ventilation system to be balanced with the proper combination of intake and exhaust ventilation through the roof. Without airflow, the roof can suffer from increased energy costs, moisture, mold, and structural damage. 

Intake air ventilation is essential for maintaining a healthy and functional home, even in the absence of intake vents through the soffits. Intake vents ensure fresh air enters the attic, preventing problems like mold, ice dams, and roof deterioration. Overall, proper airflow extends the roof’s lifespan and maintains a comfortable living environment.

Intake Air

To address the lack of intake air through your soffits, we add Lomanco Intake Vents during the roofing process. These vents are typically installed near the bottom edge of the roof, allowing fresh air to enter the attic or roof space. By incorporating these intake vents, we create a pathway for cool, dry air to flow into the roof system, ensuring proper airflow. This helps prevent issues like moisture buildup, heat accumulation, and damage to the roofing materials. Intake vents are essential for maintaining a healthy and functional home, even in the absence of intake through the soffits.

Exhaust Ventilation

A rigid roll ridge vent is installed along the ridgeline of the roof to improve ventilation and exhaust the air from your attic. We use Lomanco Ridge Vents. This allows hot air to escape from the attic or roof space, regulating temperature and preventing damage to roofing materials. The design of the ridge roll ensures consistent airflow, reducing moisture buildup and maintaining a healthy environment. It is an effective addition to promote proper ventilation and preserve the longevity of the roof.
Adding a power fan with a humidistat and thermostat will exhaust the air and provide year-round protection for the roof. We use GAF Master Flow Power Fans. This combination allows for automatic control of the fan based on humidity and temperature levels. It helps regulate moisture and temperature, preventing issues like mold, rot, and heat damage. This setup ensures continuous ventilation, promoting a healthy and well-maintained roof throughout the year.
