Common questions
What are the steps to installing an asphalt shingle roof?
Installation begins with removing the old roofing material and inspecting the underlying deck for damage. Next, a water-resistant underlayment is applied, followed by drip edge flashing along the eaves and rakes. Asphalt shingles are then installed in overlapping courses, starting from the bottom and working upwards. Finally, ridge cap shingles and proper ventilation are installed to complete the roof.
What is the cheapest type of roof to install in North Carolina?
Asphalt shingles are generally the most cost-effective roofing material for installation in North Carolina. Their widespread availability and established installation processes contribute to lower material and labor costs compared to other options. Consider the long-term performance and lifespan in North Carolina's climate when making your decision.
What is the 25% rule for roofing?
The 25% rule in roofing typically refers to the maximum slope at which certain materials or installation methods are recommended. For asphalt shingles, this often relates to pitches where water shedding is efficiently managed with conventional methods. Steeper slopes may require specialized techniques or materials to ensure adequate performance.
What is the cheapest month for roofing in North Carolina?
While roofing can be performed throughout the year in North Carolina, the spring and fall months often offer more stable weather conditions, which can sometimes lead to more competitive pricing.

The best company for your asphalt shingle roof in Raleigh will be one that understands North Carolina's building codes and climate. They should be able to detail their installation methods, explain material choices, and provide transparent estimates. Look for providers with a strong track record and references for similar projects in the Raleigh area.
