TPO Membrane Roofers: Costs, Lifespan and Alternatives

A Rainbow inspection starts at the flashings — chimney, vents, skylights — because they fail long before the field does. We look at the deck from inside the Rainbow attic as well as walking the roof; half the evidence is underneath.

The line that moves on a Rainbow quote is deck repair, so it belongs in writing at a rate per sheet rather than as an allowance. A Rainbow estimate worth comparing itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up.

We inspect roofs in Rainbow free of charge and put the findings in writing before any price is discussed. Emergency work in Rainbow costs more than planned work, for the obvious reason that nobody chose the timing.

Booking a Rainbow job ahead of the first winter storm avoids the queue everyone else joins afterwards. Active leaks in Rainbow get same-day or next-day attention; planned work is scheduled around the weather.

Repeat stains in the same Rainbow ceiling after every storm point at flashing rather than the field. Daylight through the deck in a Rainbow attic is a structural problem, not a covering problem.

A contractor who talks you out of unnecessary Rainbow work is the one worth calling back. Two warranties apply on Rainbow work — the manufacturer's on material and the installer's on workmanship.

Composition shingle is the most common covering in Rainbow and typically runs fifteen to twenty-five years here. Low-slope sections on Rainbow buildings need a membrane or coating system rather than shingle laid flatter than it is rated for.

Material choice in Rainbow should follow pitch and exposure first and appearance second. Metal suits many Rainbow roofs for lifespan and reflectivity, provided the fixing system allows for movement.
