If I have minor cracks extending the width of my house on the plaster ceiling should I be worried? PS, kids playing on the deck never came close to the violence done by these roofers. You'd have to have been there. It was like repeated earthquakes. Thanks for all your responses. (they were standing when they threw the packs around, how high the shingle packs fell from each time is a guess.)
Full packs of shingles don't weigh 100 lbs.... not even the best grade Architectual ones....I've hauled too many of them before.
Believe what you want....but a skinny 10 year thats jumping can fold a steel Queen size bedframe in half. A couple of them will do more damage to a deck than roofers doing their normal work will including the supplies.
If your decks are coming loose they are either extremely old or improperly built. Code (at least where I live in Virginia) has required they be bolted...and not just screwed or nailed THROUGH the sill plate of the house for a fair number of years now. THey should easily support the weight of over a DOZEN full grown adults....or more depending on the size of the deck.
And just because its not 20 years old...doesn't mean it was built to code....there have been many build in recent years in my area that had to be torn down and re-done when it was discovered they were unsafe, some less than 5 years old. A few only a year old.
If a heavy snowfall will put several TONS of weight on the roof depending on a number of factors without the house collapsing, a few packs of shingles aren't going to hurt it.
Houses walls will crack....thats life because the materials aren't flexible. What matters is the size of the cracks.
Simple cracks that are tight are nothing to worry about....however WIDE cracks with gaps that you can easily measure ARE a cause of concern.
I've never seen a house with plastered walls and ceiling that didn't have cracks somewhere.... Same with houses with sheetrock walls.
Someone walking heavily across a roof will sound unsettling. I've had a raccon jump out of a tree onto mine and run across it.....that was loud enough to wake me up. Yet my roof at one time had THREE layers of shingles (yes a violation of code the inspectore missed....AND weathered more than a decade of WInter snowfalls on top of that....
If you see my point....houses are more resilient than you might think. Wood frame houses as most are built are particularly so.
