The best type of roof vent depends on the size, type, and construction of your roof as well as the environmental conditions in and around your home. In many cases, an active ventilation system that draws in fresh air and exhausts air out through the attic is the most effective. Active ventilation systems include roof ridge vents with baffles, turbine vents, and soffit vents that are used together with another type of vent.

Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and roof flashing. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.

Asphalt shingle roofs are more likely to leak than metal roofs because they are more prone to uplift and damage from extreme weather, moss growth, and ice dams. Asphalt shingles also lose shingle grit over time, which decreases their waterproofing qualities. Metal is a more resilient material that will stand up better to strong winds and heavy precipitation, ultimately leading to a lower risk of leaking. As such, metal roofs add to home value with a higher ROI than asphalt roofs in most cases.

Single-ply roofing lasts for between 15 and 30 years, depending on the type you install and the climate in your area. TPO roofing has the shortest lifespan of 15 to 30 years, followed by PVC, which lasts for 20 to 30 years. EPDM roofing is the longest-lasting single-ply roofing option, with a lifespan of 30 to 40 years. Keep in mind that hail, strong winds, blown debris, and foot traffic can all reduce how long your flat roof lasts.
