When people think of roofing, they usually picture a contiguous surface or surfaces that slope in different angles and are somehow joined, but that image rarely includes one of the humblest, but most important component of any roof: the flashing. Roof flashing consists of thin stripes of material installed in the most sensitive areas of the roof, such as in the roof valleys, where two roof sections meet, around the skylight, the chimney and around other roof openings, to reinforce those sensitive areas that would be otherwise prone to develop leaks.
Flashing comes in lots of different types and can be made from many different materials, such as galvanized steel, copper or rubberized materials. Whatever the material, flashing stripes play the same role on the roof: they divert water away from the sensitive roof section. Most types of flashing are quick and easy to install (all you will need is the flashing stripe, some caulk or the adhesive material used for the specific type of flashing that you have), but they need to be inspected by roofers in Dallas and maintained whenever the roofing is maintained to detect any faults in early stages and to prevent roof damage. If any cracks, curling or damage is detected on the flashing, the stripe needs to be replaced immediately to maintain the strength of the sensitive area.
