How to install cement board as roofing
To install cement boards as roofing, begin by ensuring your roof deck is clean and dry. First, cut the cement boards to the appropriate size using a utility knife or saw. Lay the boards onto the roof, ensuring they overlap at least 1/4″ and are aligned with the trusses. Secure them using corrosion-resistant screws or nails, making sure to fasten every 6–8 inches along the edges and in the field of the boards. For waterproofing, apply a roofing underlayment beneath the boards. Ensure the joints are sealed with fiberglass mesh tape and thin-set mortar.
Steps for installation:
- Prepare the roof deck.
- Cut the cement boards to size.
- Lay the boards, ensuring proper alignment and overlap.
- Secure boards with fasteners.
- Seal joints with tape and mortar.
Attentions:
- Cement boards are lightweight compared to traditional roofing materials, making handling easier.
- They are more fire-resistant, durable, and moisture-resistant, providing superior protection and a longer lifespan than other materials.
