What counts as an emergency roof call?
An opening that lets water into the house, a limb or tree through the covering, and a ceiling that is wet and bowing are emergencies. Damage that is contained and dry can wait for a scheduled visit.
Water entering the house is the clearest emergency, because it soaks insulation and finishes within hours. Any opening that lets rain or snowmelt reach the attic counts, even if the water is only dripping now, because the same opening will get worse with the next storm. A limb through the roof is treated as a hazard in its own right, since the structure beneath it may be weakened.
Will a tarp fix the roof?
No. A tarp keeps water out while the roof is repaired properly. It does not replace damaged decking, flashing or covering.
A tarp buys time. It protects the attic, the insulation and the rooms below while the permanent work is planned, and it stops an opening from growing with each storm. The permanent repair is what restores the roof's strength and its ability to shed water, and that work is planned around the weather and any permit.
What should I do before the crew arrives?
Keep out of the attic if the ceiling is sagging, move valuables away from the leak, and photograph the damage. Do not climb onto the roof.
Safety comes first. Do not climb onto a damaged roof, do not walk a roof in wind or snow, and do not enter an attic where the ceiling is bowing or the decking looks wet and soft. Stay clear of any line that is down, and treat any tree still resting on the house as unstable.
Why does wind do so much damage here?
The Palouse has a record of strong winds, and the National Weather Service and NOAA document reported gusts that brought trees down onto homes and power lines.
The Weather Service Spokane office reports a gust of 63 miles per hour at Pullman in December 2000, with numerous trees and power lines down across the Palouse. In December 2006 it reported 61 miles per hour at Pullman, with the College Hill area hit hardest, and 77 miles per hour on West Hill in Colfax. In November 2010 a tree in Pullman landed on part of a home. These are reports from scattered stations and spotters, and they are written here as reported, not as measured on any particular roof.
How does a crew work on a winter opening?
Snow and ice make the roof slower to work and more hazardous to walk. A crew covers the opening first and completes the repair once the weather allows.
Snow on the roof, a frozen deck and short daylight all slow the work. The crew decides whether it can safely reach the opening, and if it cannot, it tarps the area from the safest position it has and returns when conditions allow. A tarp in winter also needs checking after heavy snow, since snow can load the sheet and pull at its fasteners.
