Here are some signs you need a new roof.
The duration of a roof installation or replacement depends on your home’s size and roofing material. For average-sized homes with asphalt shingles, the process typically takes one day. Larger homes or those using complex roofing materials may take between two and five days to complete.
We offer comprehensive warranties to ensure lasting quality and peace of mind.
These warranties protect your investment and reflect our commitment to exceptional service.
The cost of a new roof depends on size, materials, and installation complexity. We provide estimates and solutions that fit your budget.
It does. Darker shingles absorb more heat, which can make your attic and home warmer in summer. Lighter colors reflect more sunlight, helping keep cooling costs down. Choosing the right color can be one way to strike a balance between energy efficiency and curb appeal.
Good ventilation helps your roof and attic “breathe.” It reduces heat buildup, prevents moisture damage, and helps shingles last longer. Signs of poor ventilation include hot upper rooms, musty odors in the attic, or high energy bills. A roof inspection is the best way to confirm if your ventilation system is working properly.
Roof issues often start at vulnerable points—such as flashing, valleys, or spots around chimneys and skylights. Regularly inspecting these areas can help address minor concerns before they turn into costly repairs.
Metal roofs are very durable. With proper installation and maintenance, they can last 40–70 years, especially higher-end options like standing seam systems. This lifespan is significantly longer than most shingle roofs.
Flashing protects some of the most leak-prone areas of your roof. Reusing old flashing during a re-roof can leave weak spots behind. Replacing it ensures the new roof system is fully sealed and protected.
