Rainbow Commercial Roofing

We start at the flashings, check the deck from inside the attic, and photograph every elevation. On a Rainbow property we pay particular attention to dried-out underlayment and attic temperature.

Size, pitch, layer count and deck condition drive the number on any Rainbow roof. The line that moves is deck repair, so it belongs in the Rainbow quote at a rate per sheet rather than as an allowance.

Repair makes sense on a Rainbow roof with life left and one localised failure. Once the covering is past its service life, repairs buy months and a replacement buys decades.

Granules in the gutters, curling tabs, repeat stains in the same ceiling after every storm, and soft spots underfoot. In Rainbow, asphalt dries out and sealant pulls back from penetrations years before the field wears through.

Yes. Low-slope sections on Rainbow buildings need a membrane or coating system rather than shingle laid flatter than it is rated for, and they are quoted separately from the pitched roof.

In inland conditions, composition shingle runs roughly fifteen to twenty-five years, tile underlayment twenty to twenty-five, and coatings seven to fifteen depending on the system.

Check the licence, liability cover and workers' compensation, then ask any Rainbow contractor what happens if the deck is worse than expected — and get that answer in writing before the covering comes off.

One to three days on a typical Rainbow property, depending on size, pitch and how much deck needs replacing. Nothing is left open overnight.
