Leaves from nipa, mangrove, rumbia or sugar palm trees (depending on the region) are prepared in various ways – mostly either plait into mat like sheets or split along the ribs to be used as shingles. If properly harvested, treated, stored, built, and maintained, such a roof may last up to 10 years.

Thatching Process

The process of thatching involves several steps:

Preparation and Site Assessment

Before beginning the thatching process, a thorough assessment of the roof structure and its suitability for thatching is conducted. Any necessary repairs or modifications are made to ensure a sound foundation.

Applying the Thatch

Thatching starts at the eaves and progresses upward, layer by layer. The thatch is fixed to the roof structure using a combination of techniques, such as stitching, pegging, or wiring. The layers are carefully compacted to create a tight and water-resistant covering.

Finishing Touches and Maintenance

Once the thatch is in place, it is trimmed and shaped to achieve the desired appearance. The ridge is often adorned with decorative elements, such as thatch finials. Regular maintenance, such as patching and re-ridging, is necessary to ensure the longevity of the thatched roof.
