The number of roof vents necessary for a 2,000-square-foot house depends on several factors. The calculation depends on the net free area within the attic and whether your municipality requires a 1/150 or a 1/300 ratio of venting square feet to attic square feet. If you install vents with a square-foot opening of one, you'll need either 14 or seven exhaust vents and an equal square-foot amount of intake vents.

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.

Though cedar shakes often get confused with shingles, there are a few key differences between wood shakes and wood shingles. For one, cedar shingle prices are lower, although shingles are less durable than wood shakes. Cedar shakes are thicker than shingles (shingles range from about 3/8 to 1/2 inches thick, compared to 1/2 to 3/4 inches thick for shakes). Wood shakes are handmade, while shingles are usually machine-made. Also, wood shakes work better on steeper roofs than shingles do. While the cost of cedar shingles is more budget-friendly, there are many great reasons to choose shakes.

As long as your solar panels are properly installed without damage to your roof, they will not shorten the roof’s life span. Solar panels can act as a cover or barrier to your roof and help block external elements, such as debris, heat, and UV rays. Reduced exposure to the weather can extend your roof’s life.
