Benefits to Roofing Underlayment
Resisto underlayments are very lightweight and more comfortable to work with on the roof. These products have a greater amount of square footage per roll, which means it has wider coverage than asphalt felt products.
While being lightweight, these products are also very durable. Synthetic and self-adhesive underlayments are significantly stronger to resist moving or tearing. The material technology doesn’t allow moisture absorption and resists wrinkling and fungal growth, so the longevity of these products is more prominent than most other materials.
The harsh weather elements can also be a factor for the underlayment you require. Synthetic underlayments have a high-temperature tolerance, and they retain less heat. UV exposure has a longer timeframe, which can be beneficial if the roofing project has been delayed for any reason.
It's always helpful to know where each underlayment should be installed.
Self-adhesive underlayments shouldn't be installed on the entire roof, so it is recommended to place it in the areas where water could penetrate the roof deck.
Ice and water shield self-adhesive underlay only need to be installed in the below areas.
- Eave edges (12" inside the exterior wall)
- Rakes on gable roofs
- All valleys and hips
- Any penetrations - chimney, skylights, vent pipes, etc.
The remainder of the roof can be covered with a synthetic underlayment.
LB1236 has a granulated surface and should ONLY be used under an asphalt roof and should be covered right away.
Note: Do not use a granulated surfaced underlayment underneath a metal roof because the two can rub together. Over time this will cause a corrosion effect.
