First, roofs are symmetrical, he said.
"If you stand outside and look at your roof, it'll telegraph if there's a problem. It should be even with the road line," Marino said. "If you see a dip or swag, you could have a potential problem."
People worried about their roof caving in could also go to their home's attic and check the boards to make sure they're even and straight, Marino said.
Besides those suggestions, Marino said people should always contact a professional first. Professionals can add more boards to the home's structure for extra support and assurance, he said.
If a roof does collapse, Marino said insurance companies won't hesitate to authorize a professional to put up a temporary tarp and support beams as soon as damage is reported.
Marino said a significant concern with Sandy is the timing. Usually by the time snow falls as much as it did during this storm, West Virginians have already cleaned the leaves out of their gutters.
Not with this pre-Halloween storm, where a buildup of autumn leaves would trap snow in gutters and on roofs, he said.
"Most people probably hadn't done the maintenance they typically would've done by now: removing leaves, starting furnaces and being prepared for this kind of storm," Marino said. "People got ready [for the storm], but there's maintenance that couldn't be done in time."
Roof collapses shouldn't come as a complete surprise to residents, however, Marino said. Warning signs include sounds, such as "popping and cracking," Marino said, and a split in the home's ceilings. Also, if a roof is old, it may be time for a new one, he said.
According to the National Association of Home Builders, your roof should be inspected by a qualified roofer every three years. Marino further advised getting an inspection after a hailstorm.
"No roof is built so strong that it doesn't fail over a period of time," Marino said. "Shingles can be damaged by a hailstorm and we don't even know it. They could be cracked, have the asphalt coating knocked off of it. Shingles are very susceptible to heavy types of rainstorms."
Marino said his contracting company is still not finished fixing damage caused by the summer derecho. While there are six months of scheduled derecho fixes to repair, Marino said his men are ready to help homes damaged during this storm.
"This was truly the perfect storm. Last week we were doing air conditioning calls, this week we're trying to get people's furnaces up and running," Marino said.
