Owning a home can be challenging because of all the updates and repairs you will need to make over time. From replacing windows and outdated plumbing fixtures to installing new flooring once the carpet or laminate wears out, it is easy to see the challenges of home maintenance.
The roof is another area of the home that requires proper understanding and concern, but you may not even realize what is affecting the look and underlying durability of this important part of your home. With this guide, you will learn a few key factors that affect the lifespan of your roof.
1. Roof Material
The material used on your home is a surefire factor in determining how long your roof will last. Certain materials will last longer than others, so it's helpful to know the expected lifespans.
Asphalt shingles are the most traditional. Manufactured out of a combination of materials, such as cement fibers and composite materials, asphalt shingles are durable enough to last between 15 and 30 years.
Architectural shingles are thicker than asphalt shingles, so they create a stronger and more durable surface on the roof. On average, architectural shingles will last between 25 and 30 years.
Metal is one of the most durable options, but it is still not capable of lasting forever. Depending on the manufacturer and how well it is maintained, you can expect a metal roof to last up to 70 years.
Slate may be considered the material to have the longest lifespan. This natural material is both beautiful and durable. Manufacturers may warranty slate roofing materials for 50 years or longer, but it could possibly last a lifetime with proper care.
2. Roof Installation
Improper installation can also affect the lifespan of your roof. Certain mistakes made by roofing contractors can lead to premature wear and tear and water leaks.
For example, if not nailed down and secured properly, the shingles could easily fall off the roof. Moisture will seep in through the spaces of loose or missing shingles, which will lead to leaks and water damage inside the home.
If the roof was not designed with an adequate slope, debris and moisture will not flow off the roof. The accumulated debris and moisture places weight and unnecessary stress on the roof. To avoid added stress and the risk of damage and leaks, the roof slope should be sufficient enough to allow debris, rain, sleet, and snow to flow off the roof efficiently.
Flashing must also be installed properly to prevent water leaks that can harm your shingles, underlayment of the roof, and the interior of your home. Metal flashing must be installed around any openings or crevices, such as the spaces around the chimney and roof vents.
3. Roof Maintenance
Regular inspections are an imperative part of maintaining your roof. Document any dark spots, discolorations, or patches of green, brown, or black growth on the roof. This growth could stem from mold or algae that weakens the shingles and roof's underlayment.
Also, check inside the house, in areas such as your loft or attic, for water spots. Even small water spots indicate your roof has a leak that should be taken seriously.
Cleaning your roof regularly is also important, especially since clumps of dirt, leaves, pine straw, and other debris weigh down the roof and trap in moisture. If this water-soaked debris remains on the roof, the shingles will start to rot and decay.
Your gutters also play a large role in your roof's lifespan. Debris inside the gutters blocks water from flowing off the roof and away from the home.
All in all, you can expect moisture-soaked debris to rot the roofline and shingles. This will most likely lead to leaks and a roof replacement.
