Common questions
What is the 25% rule for roofing?
The 25% rule in roofing generally refers to the condition of the roof decking. If more than 25% of the wood sheathing beneath your shingles is found to be rotted or damaged, it's typically recommended to replace that entire section to ensure a solid foundation for your new roof.
What is the average cost to have a new roof?
The cost of a new roof in Illinois is influenced by the size and complexity of your home, the type of roofing materials you select, and any necessary underlayment or structural repairs. The specific shingles or metal chosen will play a large role in the overall investment.
What is the cheapest month for roofing?
In Illinois, you might find that the late fall or early spring months can be more budget-friendly for roofing projects. Contractors often have more availability during these 'shoulder seasons,' potentially offering more competitive pricing outside of peak demand.
Which company is the best for roofing?
The 'best' roofing company in the Chicago area is typically one with a proven track record, excellent customer reviews, and a deep understanding of local weather patterns. Look for licensed and insured professionals who offer transparent pricing and clear communication.
What is a fair price for a new roof?
A fair price for a new roof is one that accurately reflects the quality of materials, the expertise of the installation team, and the specific needs of your home. It's always best to get multiple detailed estimates from reputable roofing contractors to compare.
Can waterproof sealant help my Illinois roof?
Waterproof sealant can be a very effective solution for specific issues on Illinois roofs, such as sealing minor cracks, around penetrations, or along seams. It's a great way to prevent immediate water intrusion and can help extend the life of your existing roof system.
