Thatch Roof Conversions

Bosazza Roofing specializes in converting thatch roofs to other roofing solutions. Thatch roofs on homes, holiday cottages and lodges can be changed to other roofing types. We offer a range of different roofing products when changing from thatch, and can recommend which is best for your particular roof. 

Why do people want to change a thatched roof?

There are a number of reasons why home owners with thatched roofs may choose to convert to tiles or roof sheeting:

  • If a thatch roof is in a bad condition it can become expensive to maintain over time especially in areas with overhanging trees and lots of shade
  • Water can’t be harvested from a thatched roof and it’s becoming more and more important to have access to rain water
  • Thatch can be at higher risk of fire and the associated insurance costs can be high
  • Standard roofing products can reduce the risk of insect, bird and animal damage to the roof

How do you convert thatch to tiles?

We offer three different systems to convert thatched roofs – your choice will depend on the current condition of the roof, as well as whether you want to keep the original structure of the roof or renovate entirely:

Thatch Roof Conversion Systems

A Thatched Roofing - Over-Sheeting with flexible roof sheeting

Over-Sheeting

Our most popular system to convert thatch to tiles is over-sheeting; this involves overlaying the original thatched roof with tiles or roof sheeting. Due to the fact that the original roof is being covered, there is much less disruption to the home or inside of the building during the process of re-roofing. The insulation properties of the thatch roof underlay also means that extra insulation does not need to be installed. The original thatch roof needs to be in a particularly good condition to make this a problem free roofing option. Some roofs may need some maintenance work on the thatch before over-sheeting.

Thatch Roof Conversion - Original Structure Stays

Structure Stays

Keep the original pole structure of the roof, remove all thatch and replace with tiles or roof sheeting. This option removes all of the thatch from the roof and opens the house or building up during the process of re-roofing. This method gives you more options on the choice of internal finishes such as ceilings. Some clients decide re-lay a thin layer of thatch over the laths to create a thatch ceiling. This retains the warmth and rustic feeling of the inside of a thatched home. When you convert thatch to tiles using this method, extra insulation needs to be installed between the ceiling and roof tiles to ensure heat management in the home.

Thatch Roof being Reconstructed with new roofing

Renovate & Reconstruct

This system is for those looking to totally renovate and re-construct their roof. The entire roof covering and structure are removed, the roof is redesigned and constructed from scratch. In this case the roof can be constructed with pre-fabricated trusses or with a pole structure built on site. You can redesign and renovate your roof entirely, choosing a new roof covering, internal and eave ceilings and gutter systems. Often clients choose this system as a part of a larger renovation.

"We finally did it! We converted our thatch to a tile roof using a product called Onduvilla. No dust, leaks, no more wind chill. Living in the windy City of Port Elizabeth we previously had serious wind gusting through the thatch (absolutely freezing in winter) we were forever living in fear of bush fires and lightning storms. Maintenance on the forever decaying thatch is now a thing of the past. Jonathan’s crew have an amazing work ethic, we have tackled major renovations in the past but nothing on this scale and their workmanship is inspiring, clean, neat and steady. Thank you for giving us a new home."
