What is Rolled Roofing?

Rolled roofing is a type of roofing material that comes in large rolls, typically made from asphalt. It is lightweight, affordable, and easy to install, making it a popular choice for flat or low-sloped roofs such as sheds, garages, and even some residential homes. The installation of rolled roofing over shingles is an efficient way to extend the life of your roof, provided that the underlying structure is sound.

Benefits of Installing Rolled Roofing Over Shingles

2. Speed of Installation Rolled roofing can be installed quickly. The rolls cover a large surface area, allowing for faster application compared to traditional shingles.

3. Added Protection Adding a layer of rolled roofing can provide extra protection against leaks and moisture. This is particularly beneficial if your shingles are showing signs of wear but still have some life left in them.

4. Reduced Waste By avoiding the removal of existing shingles, you reduce waste sent to landfills, making this an environmentally friendly option.

5. Versatility Rolled roofing is suitable for various surfaces and can be applied to both residential and commercial properties, providing versatility in application.

- Condition of Existing Roof Ensure that your current shingles are in good condition. If there are extensive damages, it may be better to remove them first.

- Building Codes Check local building codes and regulations, as some areas may have restrictions on layering roofing materials.

Installation Steps

1. Prepare the Surface Clean the existing roof surface, removing debris and checking for any loose shingles that need to be secured.

2. Install Underlayment Lay down a waterproof underlayment to provide an additional barrier against moisture.

3. Unroll and Cut the Roofing Start unrolling the rolled roofing from one end and cut it to size, ensuring it overlaps properly.

4. Secure the Roofing Use roofing nails and a roofing adhesive to secure the rolled roofing in place, ensuring a tight seal against the elements.

5. Finish Edges Make sure to seal the edges and any seams to prevent water infiltration.

In conclusion, installing rolled roofing over shingles can be a practical solution for homeowners looking to preserve their roofs while saving money.
