Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

A roof pitch that’s too shallow won’t shed runoff as quickly, so you have an increased risk of water intrusion through the seams between your roofing materials. In colder climates, snow and ice will accumulate more easily on your roof, which can add enough weight to cause roof collapse and structural damage to your home.

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.

Yes, copper roof strips can help prevent shingle damage and are an alternative to algae-resistant shingles. They work in a similar way: they release copper ions that interfere with algae, moss, and other plant growth. Algae feeds on limestone in your roof shingles, and moss can uplift shingles and increase the risk of leaks. If you have issues with algae or moss on your roof, copper roof strips can help avoid damage.
