What Affects the Lifespan of Your Roofing System?

When choosing roof materials for your home, you want to get the bang for your buck. It is an essential investment, and you want to make sure it lasts a long time. Your roof’s lifespan depends on several factors, some of which are within your control and determined by your options. Keep reading to learn more about how long you make a roof last for your home!

Roofing Material

This is considered the most critical factor in determining your roof’s longevity. There is a wide spectrum of roofing materials available in the market, so make sure you pick a durable and long-lasting option.

Asphalt shingle roofs are incredibly popular in the US since they are affordable and can last up to 20-30 years. You could also consider slate, tile, and concrete roofs, which are made to last for about 50 years and over a hundred years when properly maintained. Consists of simple, corrugated panels, metal roofing can last up to 40-60 years, depending on the quality of the metal and climate conditions. On the other hand, wood roofing requires annual upkeep and can only last for about 20 years.

Weather Conditions

A roof serves as your protective shield against weather conditions like strong winds, heavy downpours, and hailstones. However, even the strongest roofing systems will begin to wear down if continuously exposed to harsh elements. You can’t predict or control the weather conditions, but you can choose the most durable roofing material that can withstand nature’s forces.

If you live in a cold area, metal roofing is your best bet since it is extremely resistant to snow and ice formation. The snow and ice will slide off, so there will be less buildup on the roof. Meanwhile, EPDM roofing membranes are perfect for those who live in places with hot climates because their composition resists ultraviolet (UV) radiation without cracking and fading over time.

Sun Exposure

You can’t see UV rays, but they can harm your roofing by attacking the chemical compounds and composition of the surface. Direct exposure to sunlight will soon accelerate roof degradation and compromise its integrity. The best way to prevent UV damage is by choosing polycarbonate roofing sheets and panels that are resistant to extreme temperatures. Polycarbonate roofing with UV protection and special coatings can handle sun rays well, lower roof temperatures, and boost indoor air quality.

Roof Pitch or Slope

This determines how the roof sheds water and affects the aesthetics and overall look of your home. A roof with a higher pitch or slope will shed water or snow faster, which means it can dry up faster. Meanwhile, a functionally flat roof will be more prone to ice dams since it doesn’t facilitate faster runoff.


Too much can be bad for the roof on your house, especially if you used darker roofing materials. Dark colors absorb more heat, which can accelerate wear and tear and damage the roof. Avoid matte black, charcoal, brown, and dark bronze if your roof takes up a lot of surface area. For warm climates, choose light-colored roofing materials to reduce heat absorption. It is crucial to select a high-quality paint finish and color right the first time to save you money from replacements.

Insulation and Ventilation

Proper roof ventilation and insulation are important to strengthen the roof and prevent heat and moisture from damaging the shingles. You can make your roof and attic “breathe” properly by adding built-in vents and exhausts to let air circulate. Adding insulation will also extend your roof system’s lifespan and improve energy efficiency. 


Most homeowners consider roofing underlayment as an accessory, but it prevents leaks and the disintegration of your decking. It acts as the first line of defense and moisture barrier to protect your roof from mold growth in the shingles. When your roof isn’t prone to condensation and humidity, roof leaks and HVAC-related issues can be prevented.

Roof Age

No matter what type of roofing material you get, it will eventually require a replacement. No roof lasts forever. The only thing you can do to make your investment worthwhile is through proper care and maintenance. You should also be proactive in replacing your roof when any issues arise. By addressing the roof damage immediately, you can avoid additional damages and save money.

Roof Cleaning and Maintenance

Lack of regular maintenance will eventually lead to cracks and cause the roof warranty to lapse. Perform roof inspections to look for major and minor damages that you may not be aware of. This should always be part of your seasonal outdoor chores to remove dirt and algae buildup. Aside from enhancing your home’s curb appeal, regular cleaning will extend its lifespan and keep it at its best.


Installation defects cause early deterioration and shorten the lifespan of your roof system. Even if you choose the highest quality materials, workmanship errors will still lead to premature roof failure and replacement. It is essential to hire a competent and experienced roofing contractor who will properly take care of your roofing needs. Only trust the licensed and best-trained installers to make the most out of your roofing. Extend your roof’s lifespan by choosing a reliable company like Pittsburgh Metal Roofing.
