Your roofing is your house’s first line of defense against the weather that mother nature brings at us year after year. Whether it is windswept rain in July or a nor’easter in February, the roofing manages all that wetness and guarantees it does not enter your house where it could cause a lot of damage.
Flashing, or weather proofing as it sometimes is called, is a simple product that a roofer will set up on your roof along with the roofing material itself. It goes around vents, skylights, pipes and chimneys and also on grooves, valleys, edges and anywhere two parts of the roof meet, and it functions as an extra line of protection against the elements. Flashing comes in slim sheets and is designed to deflect water off the surface, whether that surface is shingles, wood, metal or tile, and works to prevent any wetness from getting into the roofing material and leaking into your basement. If it is set up the correct way, water will have to move against gravity to go through the roof, something that water does not tend to do, but which allows the integrity of your roof to stay unchanged. Stainless-steel, Copper, zinc, aluminium, lead and nowadays, rubberized or a water resistant synthetic content can all be used as flashing. Copper, for instance is a fantastic content for flashing since it is simple to work with, simple to solder and has a high resistance to the weather and other products being close to it. Since the aim is to stop water from getting under the roofing shingles and causing damage, flashing is a fundamental element of any properly set up roof. A professional roofing contractor knows that flashing must allow for the natural contraction and expansion of materials while still maintaining its leak-proof seal.
