The most common type of roofing material is asphalt shingles. They are relatively inexpensive, easy to install and come in a wide range of colors and styles. They also come with a steep price tag, as they require periodic replacement due to weathering.
Asphalt shingles are made from recycled materials such as recycled rubber and glass bottles. This makes them more environmentally friendly than some other materials, including concrete tile or slate shingles.
Fiberglass shingles are made from fiberglass strands that are melted together under high pressure to form the shingle shape. The fibers are then sprayed with asphalt and allowed to cool in the shape of a finished product.
The most expensive type of roofing material is slate tiles, but this is because they are usually handcrafted by skilled artisans who use only the highest quality materials available. Slate tiles can be used on any style of house regardless of whether it is a Victorian mansion or an ultra-modern glass-and-steel skyscraper; however, they also require regular maintenance because they are not waterproof by themselves (they must be sealed).
Built up roof with gravel
If your roof is built up with gravel, it’s important to maintain a regular cleaning schedule. This will prolong the life of your roof and ensure that it continues to protect your home from the elements.
A tar and gravel roof is a good choice for many homes because it can be installed quickly and easily, even by do-it-yourselfers. The gravel provides traction for walking on the roof and helps prevent snow from accumulating.
How to Clean Your Tar and Gravel Roof
Regularly cleaning your roof is one way to maintain its appearance and extend its life. Here are some steps you can take:
Use a pressure washer or garden hose to remove loose dirt from the surface of your roof. Pay special attention to areas where leaves collect or other debris accumulates.
If moss or fungus starts growing on your roof, spray it with an algaecide solution and scrub away any remaining growth with a stiff brush or broom.
If your roof has algae growing on it, you can use a solution of bleach and water in place of an algaecide solution. Dilute 1 part bleach with 3 parts water, then apply it according to manufacturer’s instructions using a spray bottle or garden sprayer
