There is so much more to your home’s roof than simply adhered rows of shingles. Tracking from the inside of many homes and up out of the roof are components from bathroom or kitchen exhaust fan vents, water heater pipes, ducts and vents connected to rooftop HVAC units, chimney stacks and more.
With all of these openings leading down into your house, you are probably wondering how rainwater keeps from coming in. This is where roof flashings, flashing angling and gravity come in.
All about flashings
In the basic sense, roof flashings are the materials that set between the primary roof and things like the aforementioned objects that do not get covered with roofing materials. Flashings are like a protective barrier for the otherwise exposed sections of housetops, where shingles can’t cover because of an object.
For example, the base/stand of a rooftop air condition unit cannot have roofing material over it. Instead, metal flashings are placed between the unit’s base and the top of the roof’s shingles to prevent water from coming through. If water is coming in, then you will need to contact local roofing services in Ambler for fixes.
Looking up at a roof where roof flashings are, you are likely to see different shades of red rust forming off the sides. You might see rust stains below and off to the sides of metal elements on the roof that are rusting themselves. After all, most metal does rust! Have a professional come out to inspect all up and down the red sections to see if the problem is great and to make any needed repairs.
Locating and deciphering rust on your roof is a good thing because you don’t want a small, fixable problem to transform into a big one:
- Components could weaken from rust and fall off, not only damaging the component, but the roof as well.
- As the rust continues to grow and spread, the newly unprotected parts of the roof can send water through and into your home.
- Rust on flashings around water heater pipes can be a sign of pipe leakage, either due to corrosion or the pipe might be too hot.
- A concentrated area of red rust stains under a chimney could be traced back to a galvanized metal chimney cap.
If you want your roof flashings to last as long as the roof, then install a quality flashing material appropriate for such a job. Metal flashing materials include copper, aluminum, lead, stainless steel and galvanized steel. Flashings can also be made of plastic or rubber. They must be placed in the proper locations around objects on or protruding from the roof to assure the deflection and diversion of rainwater away from roofing seams and areas where water tends to pool.
There’s no better way to know the job is being done right than to schedule an expert in roofing services in Ambler to come out to inspect, repair, replace or install your home’s roof flashings.
