The Fire Risk:
Thatch was flammable—a single spark from the chimney could ignite the roof, destroying the building. This risk was managed through careful chimney design (extending chimneys well above the roof, using spark arrestors), but thatched buildings still burned more easily than tiled or slated structures.
The Animal Damage:
Birds, rodents, and insects found thatch attractive—birds nested in it, rodents burrowed through it, insects consumed it. This was constant problem requiring vigilance and periodic repairs.
Some thatchers incorporated deterrents—wire mesh preventing birds from nesting, certain plants repelling insects—but animal damage was inevitable cost of using organic material.
The Weather Extremes:
Severe storms could strip thatch from roofs, heavy snow could crush poorly supported structures, ice could trap moisture and cause rot. The thatcher had to account for local weather patterns, installing thatch robust enough to survive typical conditions.
