Using an ice and water shield underlayment under a metal roof is a good way to protect the roof and your home from damage in colder climates that see a lot of winter weather.

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.

Thatched roofs last for between 30 and 50 years in most cases, which is longer than most asphalt roofs. However, getting that life span from your thatched roof requires more maintenance than you’d need for most other materials, including fireproofing, brushing, cleaning, and rethatching as the material gets worn down. You’ll also need routine inspections to ensure you’re not at risk of leaks.
