A flat roof that's ponding water is a flat roof with a problem. We install tapered insulation systems to create positive drainage to your scuppers or interior drains. No more standing water after rain.

Roof coatings can extend the life of your commercial roof by 10-15 years for a fraction of replacement cost. We apply silicone and acrylic coatings over existing TPO, EPDM, and metal substrates. Not every roof qualifies. We'll be straight with you.

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Cornell). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

Annual roof inspections catch small problems before they become expensive ones. A cracked pipe boot is a $150 fix. Ignoring it means $3,000 in ceiling and wall water damage. We recommend an inspection every 2-3 years for roofs under 10 years old, and annually after that.

After we tarp and secure your roof, we document everything for insurance purposes. Photos, measurements, damage descriptions. Your adjuster gets a professional report, not a handwritten note.

Tubular skylights bring light into tight spaces. Closets, laundry rooms, interior bathrooms. They use a reflective tube through the attic space, so they work even when the roof is far from the ceiling. Installed in a few hours.
