"This experience was second to none! EVERYONE on the team was respectful, and professional throughout the entire project. The sales rep. and project manager carefully listened, and helped us decide on a roofing system that was right for our home. All materials were delivered on time, and before the project began, as promised. The supervisor arrived well before the roofing technicians. The lead technician, and technicians arrived on time, made the introductions, and immediately began the work. My home, and property were protected from the removal of roofing materials, at all times. There are often unforeseen issues that arise with construction projects, and I was consulted every step of the way, BEFORE any action was taken! My roof was completed on time. The technicians took pride in their craft, and their mastery was evident in the beauty of our new roof. The yard was left free of all roofing debris, it was if no one was ever there. My recommendation is an enthusiastic YES!"

From the initial estimate to the completed roof installation, the team was professional, punctual, and highly skilled. They kept the worksite clean, communicated clearly throughout the project, and completed the job on schedule. The quality of workmanship exceeded my expectations, and my new roof looks fantastic.

Roofing questions, answered by experts

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

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.

Yes, a new roof will add value to your home, often providing a return on investment (ROI) of between 60% and 70%. Not only will a new roof boost curb appeal, but savvy homebuyers will also know that a new roof means they won’t have to worry about roof leaks and related damage for years after closing. They’ll also know that they’ll save money by potentially having decades before they need to worry about paying for repairs or replacement.

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.

In general, you should consider replacing your roof if more than 30% of it is damaged. This includes several missing shingles, large spots of granule loss, extreme curling or cracking, structural damage to the roof's decking, or multiple areas of leaks. All of these issues could indicate compromised structural integrity that requires roof replacement.
