Van Nuys Roofing & Commercial Roof Repair

Check the licence, liability cover and workers' compensation before any Van Nuys contractor starts work. Two warranties apply on Van Nuys work — the manufacturer's on material and the installer's on workmanship.

Repair makes sense on a Van Nuys roof with life left and one localised failure; beyond that it is money spent twice. A Van Nuys estimate worth comparing itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up.

Annual inspection on a Van Nuys property typically adds two to three years to the back end of a roof's life. Two visits a year keeps a Van Nuys roof honest: clear valleys and gutters before the rains, check flashings after the first storm.

We look at the deck from inside the Van Nuys attic as well as walking the roof; half the evidence is underneath. On a Van Nuys tile roof we lift field tiles in two or three places to date the underlayment, which takes about fifteen minutes.

Van Nuys takes its rain in short heavy bursts, so drainage that sat dry collecting debris has to move everything at once. Heat is the main ageing force on a Van Nuys roof, with surface temperatures running well above the air reading for months.

Nothing is left open overnight on a Van Nuys job — the deck is dried in the same day it is exposed. Flashing at every penetration is replaced rather than reused on a Van Nuys roof.

Repeat stains in the same Van Nuys ceiling after every storm point at flashing rather than the field. Granules in the Van Nuys gutters are the earliest honest warning that a shingle roof is past halfway.

Low-slope sections on Van Nuys buildings need a membrane or coating system rather than shingle laid flatter than it is rated for. Tile on a Van Nuys property outlives its underlayment by decades, and the underlayment is the part doing the waterproofing.
