Learning how to tarp a roof is straightforward, and deciding whether to do it is the part that matters.
A roof tarp is a stop to the loss, not a repair. The storm and roof guide covers the damage underneath, a roof leak in heavy rain is usually what sends people up a ladder, and Emergency Services 24H routes the job to licensed roofers nearby.
Roofers use screwed battens over the tarp edge rather than staples.
A tarp without that fixing peels in the first gust, so secure tarp edges with battens, tarp straps or sandbags.
Put a tarp over the ridge wherever you can: water finds a seam.
Before you start: assess roof damage from the ground, check weather for the next dry window, and pick the ideal time of day for light.
To secure a tarp without nails on a metal roof or a tile roof, sandbags and rope over the ridge are the honest answer, and an adhesive roof patch is the only thing that sticks to a wet surface.
Put a tarp over the ridge wherever you can, because water finds a seam. A leaky roof at a valley or chimney needs the tarp carried past it. On a flat roof a leaking roof ponds instead of shedding, so the fix is different again.
Before you start, assess the damage from the ground and check the weather for a dry window. Heavy duty waterproof roof tarps outlast the cheap blue ones.
Go or no-go: read this before the ladder
Any one of these means do not climb
Wind, rain or a wet or icy surface; a steep pitch; decking compromised by impact from a tree or debris; darkness; working alone; a damaged service mast or any line nearby.
None of the pages ranking for how to tarp a roof put that gate before the procedure, which is how a how-to becomes an injury.
