Common questions
What is the 25% rule for roofing?
The 25% rule in roofing generally applies to the roof decking. If more than 25% of the plywood or sheathing is found to be damaged or rotted during an inspection, it's usually recommended to replace that entire section to ensure a stable base for your new roofing materials.
What is the average cost to have a new roof?

What is the cheapest month for roofing?
In Pennsylvania, you might find that the shoulder seasons, such as late fall or early spring, can offer more competitive pricing for roofing services. Contractors may have more availability during these times compared to the peak summer construction period.
Which company is the best for roofing?
The 'best' roofing company in the Philadelphia area is often one with a strong local reputation, extensive experience with Pennsylvania's weather, and positive customer feedback. Look for licensed and insured professionals who provide detailed quotes and clear communication.
What is a fair price for a new roof?
A fair price for a new roof is one that reflects the quality of materials, the skill of the installation crew, and the specific demands of your home's roof. Obtaining multiple detailed estimates from reputable roofing contractors is the best way to ensure you're getting value.
Can waterproof sealant help my Pennsylvania roof?
Yes, waterproof sealant can be a highly effective solution for specific issues on Pennsylvania roofs, such as sealing minor cracks, around vents, or along seams. It’s a great way to prevent immediate water intrusion and can help prolong the life of your existing roof.
