Yes, a roof blister can cause a leak if it gets to the point where it pops. Prior to popping, a roof blister is just an aesthetic issue, but once it pops, you’re left with a small hole in the shingle. Water from rain and snow can easily get inside this hole and interact with your underlayment, roof decking, and the building material below.

While the terms are often used interchangeably, wood shakes and wood shingles have notable differences, primarily in their manufacturing and appearance. Wood shingles are machine-cut on both sides, resulting in a smooth, thin, and uniform product. In contrast, wood shakes are typically hand-split or sawed on only one side, giving them a more textured, natural, and rustic appearance. Due to these manufacturing differences, shakes are generally thicker, heavier, and less uniform than shingles. They are also more expensive. Homeowners seeking a more rustic aesthetic often choose shakes, while those preferring a more uniform look may opt for shingles. Both are installed in an overlapping pattern to create a durable, weather-resistant roof.

Using a staple gun to hang Christmas lights on your roof or shingles is not recommended. Puncturing your roof with staples can cause damage, leading to cracks, leaks, and exposure to the elements. Staples are also less reliable than other methods like roof clips. For a safer alternative that won't damage your roof, use shingle tabs.

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.
