Most customers who experience roof leaks do not think much about the flashings. However, the flashings, when deteriorated or unsecured, can lead to a leak problem. Roof flashings are fitted to maintain a watertight seal on a roof – something that is important to UK residents.
Older Roof Flashings
Historically, roof flashings were made from lead. That is because the metal can be easily moulded without the worry of splitting or cracking. Now, businesses that provide affordable roof repairs in Stoke-on-Trent add flashing that is made of other materials, such as plastic, rubber, or zinc. If lead is used, it is typically protected with a waterproof pan.
How Flashings Help
Fitting flashings is important, as doing so provides the following:
- Protection from the entry of rainwater inside a home
- A barrier against damp – moisture that can lead to ceiling instability
- A safeguard against mould and mildew
How the Flashings Are Fitted
When flashings are fitted with a new roof, they usually are placed before roofs are tiled. If chimney stack flashings are fitted, they usually are fitted two on each side. The lower flashing piece is fitted beneath the tiles or shingles. The top flashing piece is fitted inside a groove that has been chased out of the brickwork’s mortar. Afterwards, the top edge of the flashing is fitted inside the groove and resealed with mortar. It is pressed down so that it conceals the bottom flashing.
When the flashings are fitted in this fashion, they create a watertight seal – a seal that will make your new roof perform better and maintain your home’s structural integrity.
