It's no secret that all roofing doesn't last the same number of years before it needs to be replaced. But all too often, people are unaware of the major reasons why a roof lasts as long as it does and what they can do to get the most out of their roofing.
Here are 7 of the most important factors affecting how long your roof will last. Some of them you can control, while others you cannot. But doing all you can to extend roofing lifespan will pay big dividends.
1. Roofing Material
The single biggest factor affecting roof lifespan is clearly that of roofing material. Asphalt shingles are most commonly used and typically last 20 to 25 years, which is reflected on their manufacturer's warranties. Tile and metal shingles are also frequently used. Look for a contractor who can recommend the most durable brands and who can give you a realistic estimate of each material's life expectancy.
2. Quality Installation
The way new roofing is put up can have a significant impact on how long it stands up to the years. Proper placement of shingles and fasteners and adhering to all manufacturer's instructions will both gain more durability and protect your product warranty.
To prevent leak, prevent disintegration of your roof decking, and keep moisture and mold from building up and weakening shingles, a heavy duty roofing underlayment should be used. The underlayment's presence also backs up the shingles, adding strength and preventing slippage.
4. Insulation & Ventilation
By adding insulation to your attic and installing attic fans and vents, you can decrease the heat level of your shingles during the hot summer months. In colder climates, good insulation can help prevent ice dams. Additionally, having the correct ventilation ratio can help reduce moisture build up. All of this can assist in de-stressing shingles and getting extra years out of them.
5. Roofing Color
Darker shades of roofing material can absorb heat and hold it for a long time, while lighter shades have less trouble with this. For this reason, you might want to consider using, say, a gray as opposed to a pitch black if possible. Given other factors put in your favor, roof color may not be the most crucial issue, but it will have at least some impact on roof longevity.
6. Roof Slope
You may not be able to change the slope of your roof, but one should at least be aware of the fact that lower sloped roofs take longer to shed moisture after a rain and also are more easily damaged. If you have a medium to steep roof, great; otherwise, take extra care with your low slope roof by investing in tougher roofing materials and by getting one or two roof inspections per year.
7. Climate Patterns
Another factor we can't control that affects roof life is the weather. Climate, weather, and wind or hail storms can all have an impact. The key here is to choose a material that is well suited to the climate zone your house is located in. And if your roof does suffer blows from a major weather event, be sure to get an inspection and any needful repairs without delay.
