Properly stack the tiles on a roof

 

Please be careful when stacking tile packs on sloping roofs.

To save time, most roofers prefer to stack several packs of shingles on the roof before starting to install them. However, shingles can be damaged if stored or stacked incorrectly, which can reduce the life of the roof. Proper stacking of tiles is also critical to avoid damaging other roof components.

 

This is essential when properly stacking asphalt shingles on a roof. This article details these tips:

 

On steep sloping roofs, nail a table just below where you are going to place the tile packs. This will prevent packages from slipping, which could be dangerous and damage the roof.

Carefully place packages on the floor. Wait until they are on the floor before removing the shingles from the packages.

Packets of 3-language shingles can be carefully placed on the ridge of the roof or lime lesa, as long as not too many packages are placed in the same place. Laminated tiles should not, preferably, be bent over the ridge of the roof or lime lesa.

Do not stack too many packs, so that there is no risk of them crumbling. A package usually weighs between 75 and 80 pounds, so stack only a few to avoid putting too much pressure on the roof and damaging it.

Choose a new location for other packages, so the roof doesn’t have to bear too much weight in one area. This also makes it easier to access shingles when you’re working on different parts of the roof.

Avoid stacking packages near vulnerable areas of the roof where damage, including vertices, is most likely to occur.

 

Whenever possible, stack tiles only on flat surfaces.

 

Some contractors will intentionally stack tile packs on the roof ridge. This process is known as “breaking packages” because it helps separate the tiles from each other at 3 tabs. However, this must be done with care. If you forcefully release the packages, you may damage them or the roof, especially if it is cold.

 

In addition, breaking packages for laminated tiles is not recommended because their two-layer construction resists bending. Bending them could damage them or misalign the layers. Instead, it is ideal to place them flat.

 

In the image above, you can see that the roofing team is unloading the tile packs with the help of a conveyor belt. However, they are stacking too many packages in one place. Concentrating the load on a small area can cause long-term problems with the roof structure.

 

The Dangers of Stacking Tiles in the Heat or Cold

 

Asphalt shingles are more malleable in heat, so you’ll need to be especially careful when moving a hot package. In addition, it may be more difficult to remove shingles at 3 tabs from the package in hot climates because the sealer on each tile is lined up in the center of the package and can adhere to each other. This is not usually the case with laminated tiles because they are packaged in such a way that the sealer is at the edge of the packages, not in the center.

 

The solution to this adhesion is simply to position the tile packs at 3 tabs so that the granular side is facing up. This can make it easier to remove the individual tiles from the package.

 

Also consider that the sealer on the asphalt shingles is activated by heat. To prevent early activation, store tile packs in the shade as much as possible. When you put them on the roof, take advantage of the shaded areas.

 

In very cold weather, asphalt shingles are less flexible and are more likely to break, especially limestone and ridge shingles. Some contractors will place these packages in the cab of their truck to heat the tiles before installing them. Either way, extreme care must be taken not to drop tile packs forcefully when performing roofing projects in cold weather*.

 

Avoid debris when stacking tiles

 

Although you must work on a clean surface, debris can fly toward the roof while you are installing the tiles. If debris accumulates on the tile adhesive strip, the tiles will not adhere properly, limiting the roof’s wind resistance. Keep shingles in their packaging until it’s time to install them to reduce your exposure to dust, dirt, or other debris.

 

If you use asphalt shingles or other products, stacking the materials on the roof requires that safety be taken into account to reduce the risk of damage to the roof and its materials.
