Roofing FAQs, answered by experts

It’s the reverse of home de-winterization. To winterize, you purge your plumbing system (including your water heater and all piping) of water. Some experts also recommend filling fixtures with an antifreeze solution. Other tasks involve winterizing sprinklers, sealing foundation vents, check weatherproofing around doors and windows, and more.

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.

The warranty for algae-resistant shingles varies by manufacturer, but the industry standard is 25 years for overall shingle durability and lifespan and between 10 and 15 years for algae resistance. Some products come with longer warranties for discoloration of up to 30 years. Check warranty coverage for the shingle and algae protection before deciding on a roofing product.

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.

The ideal color for your roof depends entirely on your preference. If you’re looking for something classic, gray, brown, and black will rarely steer you wrong. A roof with a pop of color like green or red can be sophisticated and elegant when paired with the right colored siding. Decide what vibe you’re looking for and choose a color palette that suits you.
