Learn How to Re-Roof an Asphalt Shingle Roof

Asphalt Shingles are a cost-effective and durable solution that can last for decades
The lifespan of asphalt shingle roofs varies depending on several factors, including climate, ventilation, and maintenance.

In general, asphalt shingle roofs can last anywhere from 15 to 30 years
Designer and architectural shingles can last up to 50 years with proper care. 

Shingle lifespan can be reduced due to extreme weather
Poor ventilation, and lack of maintenance can significantly reduce the lifespan of an asphalt shingle roof as well. For example, hailstorms or heavy winds can damage or dislodge individual shingles leading to leaks and water damage.

An asphalt shingle roof may not require immediate replacement
Just because your shingles are over 20-years old doesn’t mean it is at the end of its lifespan. Your roof should be inspected regularly for signs of wear and tear or damage that may compromise its integrity.

Signs Your Shingle Roof Needs to be Replaced

Here are some signs that indicate it’s time to re-roof your asphalt shingle roof.

First, if you notice that your roof is leaking or if you see water stains on your ceiling or walls. Even small leaks can cause significant damage over time if left untreated.

Secondly, check for missing or damaged shingles. If you see any bare spots where the underlayment is visible or if there are damaged or curled shingles, it’s time to replace them.

Thirdly, look for signs of wear and tear on your roof. If it’s been more than 15 years since you last replaced your roof and you’re starting to notice significant wear and tear like granule loss or cracking on the surface of the shingles, then it’s a good idea to start thinking about re-roofing.

Finally, keep an eye out for algae growth on your roof. Arizonans don’t have to worry about this – nonetheless, it can be an indication of excess moisture which can lead to rot and decay over time.

Cost Effective Re-Roofing Techniques

One option is to opt for a layover installation
This re-roofing technique involves placing new shingles on top of the existing ones. This approach eliminates the need for tear-off and disposal of old materials, resulting in lower labor costs and reduced waste.

Another cost-saving measure is to choose archetectural shingles
This will reduce the cost for material instead of using higher-end options like designer shingles. While they may not offer the same aesthetic appeal, they still provide adequate protection and come at a significantly lower price point. Additionally, choosing a lighter-colored shingle can help reduce cooling costs during hot summer months by reflecting sunlight and heat away from your home.

Prepare Your Home for Re-Roofing Day/Week/Month

The length of time to re-roof the roof is dependent on you. If you are re-roofing while learning and doing it yourself, prepare for a month of or so of work. If you know a little about roofing, prepare for a few weeks. If you are a roofing contractor, prepare for a day or two unless it is a big/commercial job.

Before the roofing crew arrives, make sure to clear the area around your home of any debris or obstacles
By having clutter around the exterior of your home it will hinder their work. This includes moving vehicles, lawn furniture, and outdoor equipment out of the way.

Cover any delicate landscaping or plants near the house
Do this with tarps or plastic sheeting to protect them from falling debris. If you have any satellite dishes or antennas on your roof, make sure to disconnect them ahead of time.

Inside your home, remove any fragile items from walls or shelves
These items could be affected by vibrations during the re-roofing process. Cover furniture with sheets to protect them from dust and debris that may fall through the roof during construction.

Now, it is time to install your new roof. You can get more information about that in our article “Asphalt Shingle Roof Installation“.

It is also important to communicate with your roofing contractor
Do this about any specific requests you may have regarding noise levels or scheduling concerns that could affect you or your neighbors. By taking these steps to prepare your home and property for re-roofing day, you can ensure a successful project with minimal disruption to your daily routine.

Maintenance to Extend the Life of your New Roof

Congratulations on your newly-replaced asphalt shingle roof! To extend its lifespan and preserve its beauty, it’s essential to perform regular maintenance. Here are some tips to help you keep your roof in excellent condition:

1. Clean your roof regularly: Missing nails, holes, rotten wood and clogged gutters can cause water to back up under the shingles, leading to leaks and damage.
2. Trim nearby trees: Overhanging branches can scratch or damage the shingles, and falling leaves can clog gutters.
3. Inspect for damage after storms: High winds, heavy rain, and hail can cause damage to your roof. Check for missing or broken shingles and have them repaired promptly.
4. Schedule regular inspections: Hire a professional roofing contractor to inspect your roof annually or biannually to detect any potential problems early.
5. Don’t walk on the roof: Walking on the roof can cause damage to the shingles and increase the risk of accidents.
