A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.

Once framing is complete, you will need the following materials to roof a house:

• Wood sheathing

• Drip edge, a.k.a metal flashing

• Underlayment for waterproofing

• Roof covering, like metal or asphalt shingles

Metal roofs do not inherently leak more than shingle roofs; when properly installed, they are generally less likely to leak. Asphalt shingle roofs are more susceptible to leaks due to factors like wind uplift, damage from extreme weather, moss growth, and ice dams. Over time, asphalt shingles also lose their protective grit, which reduces their waterproofing capabilities. In contrast, metal is a more resilient material that stands up better to heavy precipitation and high winds. However, metal roofs can develop leaks if they are poorly installed, have improperly sealed fasteners, or experience issues from thermal expansion. For this reason, professional installation and regular maintenance are crucial to ensure a metal roof's longevity and superior protection against leaks.
