Roofs play a key role in shielding a house from the elements. Due to exposure to harsh conditions, highly durable roofing materials are recommended. Most manufacturers produce roofs that can serve their purpose between 25 and 30 years. However, there are many variables to consider when determining their lifespan.
What details impact the longevity of roofs?
MATERIALS
Most of your roof’s durability is attributed to the material. Asphalt shingles are some of the most popular options since they offer terrific trade-offs between sturdiness, energy efficiency, and curb appeal. Although they boast a decent lifetime (25-30 years), they pale in comparison to metal (40-80 years) and tile solutions (50–100 years).
THE ELEMENTS
Nature is the arch-nemesis of any roof. While various products can easily endure corrosive and detrimental elements, their lifespan may be shortened by intensive exposure. The same goes for high winds, hailstones, and heavy downpours.
SUN EXPOSURE
Heat accelerates roof deterioration, especially if the materials are dark and can absorb more sunlight. Thankfully, many products, such as asphalt shingles, provide powerful resistance to UV rays.
On the other hand, lack of sun exposure can lead to a different problem — moss growth. It occurs in areas with a cool and moist climate without enough sunlight. It keeps moisture on the surface, putting a lot of strain on the roof.
INSTALLATION
Poor installation is a common cause of roof failure. Even with the best roofing material, installation errors can result in early deterioration, warranting premature replacement.
VENTILATION
Inadequate attic ventilation heats roofing materials from the inside. Asphalt shingles are especially susceptible to this. The shingles can cause condensation to build and make wooden roof decks vulnerable to water damage.
INSULATION
Poor insulation can result in extremely high temperatures in the attic. Coupled with improper ventilation, regulating the effects to the roof can be challenging. Consequently, the roof’s lifespan is significantly reduced.
PITCH
The roof’s slope defines its capacity to remove water. Therefore, resilient roofing systems are limited regarding the amount of pooling they can tolerate before losing their strength. For this reason, flat constructions are a better fit for low-slope roofs.
MAINTENANCE
No matter how tough a roof is, it won’t last without maintenance. Neglecting its condition speeds up the aging process and diminishes its ability to protect the house. On top of that, forgoing maintenance duties may void the warranty.
AGE
Finally, age catches up with the finest and sturdiest roofs. Therefore, always consider your roof’s age when determining whether to repair or replace it. In many cases, old structures aren’t worth saving.
With a wide range of roofing materials available, choosing the right option can be tricky. To find the right fit, consult a reliable roofing company. With ample experience, they’ll help you select the right product and offer even more tips on prolonging its lifespan.
