SKYLIGHTS

Cornerstone Roofing can replace your existing skylight lids.  Skylight lids typically last as average of 20-25 years. From fixed lids to opening, from clear to tinted, we can give you many options for replacement.  Bring natural light into small spaces such as bathrooms or closets by adding a Solatube.

Our Repair Division is made up of a dedicated team of skilled technicians who focus primarily on finding and repairing roof leaks. We can diagnose ventilation imbalances, determine if a roof accessory has failed, investigate tricky anomalies or suggest a timeline for replacement if necessary.  Our service department provides emergency storm damage response and so much more.

GUTTERS & Downspouts

Cornerstone Roofing can service all your gutter needs. Our trained installers can repair or replace your gutters during a Roof Replacement. We can also suggest ways to reconfigure your gutter system to better serve the migration of water around your house. 

Roof Maintenance

The purpose of roof maintenance is to protect your investment and prolong the life of your roof.  Annual maintenance helps keep your roof looking good and performing like it should, while eliminating costly damages to your home in the future. Cornerstone Roofing can provide an annual roof maintenance contract specifically designed for your home.

Carpentry

We have extensive experience in rot replacement including sheathing repair, fascia replacement, barge board changes, rafter tail repair and other carpentry needs. Our Repair and Re-Roof Divisions have carpentry capabilities and work can be performed on a Time & Materials basis.

Masonry/ Chimney Work

Your masonry chimney should be kept clean of moss and algae.  Masonry should be inspected and sealed to eliminate water intrusion into the attic space.  Counter-flashing should be inspected and replaced on average every 30-40 years.  Cornerstone Roofing will visually inspect and recommend any needed improvements.
