Cornerstone Roofing installed a new roof on our home and did an exceptional job. From the first meeting with the estimator to the ongoing communication with the company about the schedule, everyone was polite, respectful, and on time. Our estimator did not try to upsell us on their products and was thorough when providing us information about our various choices. We had an old cedar shake roof that needed to be removed with underlying plywood decking also needing replacement. When ripping off the old roof, one of our first floor screens ripped and the company quickly and seamlessly honored the pricing for its replacement. The customer service was exceptional. The roofers were careful to protect our plants and shrubs and did a fine job cleaning up each day. Our new roof looks great--we purchased the Presidential Shake TL (an asphalt composite) with an exceptional warranty. We are very pleased and happy that we used Cornerstone.

Mobile home roof replacement cost typically ranges from $3,000 to $8,000, making it generally more affordable than traditional home roof replacements, due to smaller size and simpler structure.
It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
