Important Things to Consider When Buying Roof Flashings for Your Home

Most people expect their roofs to perform for a minimum of 15 to 20 years. With certain types of products, some roofs can even be expected to last 50 to 80 years. The actual lifespan of your roof, however, will also depend greatly on the accessories or features it has.

Roof flashings are of some of the most important roofing features any house should have. They are the transition materials and media between the main roofing materials and the other items that do not get covered with these materials. These flashings are frequently installed on the chimney, the vent, on the edges of the roofs and walls, and on roof peaks and valleys, either under or over the roofing material.

When buying roof flashings, the first thing you have to consider is its material. Roofing experts recommend that you should buy flashings made of materials that have the same or a longer life span as your roofing material. This way, when it’s time to replace your roof due to wear and tear, you can also have the flashings changed, and not before it.

The roof flashing should also be able to handle the constant expansion and contraction between roofing products and other materials which are not roofing products. The sun can create very hot surface temperatures during daylight hours and cause roofing materials to expand. In the evening, the temperature drops and the materials contract. Seasonal changes can also cause the framing lumber to shrivel and swell depending on the humidity and wood moisture content. This shrinking and swelling can cause the roof coverings and rafters to move. The flashing materials you should select must be able to withstand such movements and continue to be leak-proof. 

If you’re having a hard time selecting the right flashing product for your home, finding the right supplier can help you out. Aside from having a wide range of roof flashings to choose from, you can have them made customised according to your specific requirements. You can even get your custom-made flashings on the same day you order them.
