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.

More and more insurance companies are writing torch down applications out of their liability insurance for contractors. If torch down is covered, they generally require a worker to stay on site for two hours after the last flame is extinguished.

For this reason, cold application modified bitumen—also known as “peel and stick”—is becoming more popular, and torch down is decreasing in popularity. Modified bitumen is taking its place, as it uses both hot and cold applications.

Whether or not the terms of your roofing estimate are negotiable depends on the contractor. Some professional roofers will be willing to budge on labor fees to some extent, while others will simply walk away from the potential work rather than lower their fees. In most cases, it’s best not to negotiate the terms, as lower labor charges could lead to your contractor cutting corners. Material costs aren’t negotiable, but you could purchase them yourself to try to save on delivery fees and markups.

You should definitely be wary of roofing contractors who offer significantly lower prices than their competitors. Most roofers in the area are all dealing with the same cost of materials, and labor costs are often comparable, too. If they’re significantly cheaper than other companies around, it could be a scam. Read reviews and ask other roofing companies and contractors if they’ve heard of the suspected scamming company.
