What Can Go Wrong When Replacing a Roof?
It’s equally as tough to replace a roof as building one from the ground up. According to Clear Vision Construction, many signs indicate when you should repair or replace your roof, and when you make this decision, it is best to nail it on the first try.
This is why it is advisable to hire an experienced roofing company in Portland to ensure the complete success of your job with no flaws. However, we prepared a list of possible mistakes made during a roof replacement process that can affect you long-term if the roofing company does not pay attention.
Using Low-quality Piping Components
Rooftop vents are required to remove gas from your kitchen and bathrooms. On the other hand, ventilation pipes have become a common source of rooftop leaks. Because many roof repair contractors employ low-quality collars around the bottoms of these pipes, they don’t last very long.
Contractors might make errors while cutting collars to size, in addition to quick wear and tear. Even minor errors can result in fissures that grow over time, allowing more water to penetrate the roofing materials.
Not Including Ice and Water Shields
An ice and water shield has been used to seal roof eaves during repairs for years. If you live in rainy regions, you’ll want to make sure your roof repair contractor uses ice and water shield in vulnerable spots. You’re more likely to see leaks and water damage if you don’t have it.
Some roof contractors frequently make the error of relying on caulking for water resistance. Usually used for windows and doors, caulking shrinks and expands, resulting in fractures over time if used as a substitute for ice and water shields. Water will flow into the roof through these fractures, causing more damage.
Wrong Layer Order
The process of roof replacement is more than just changing the shingles. The project is much more than simply the top layer. Every roof replacement contractor is aware of the several layers required for success. However, adding a layer out of sequence is a typical blunder that compromises overall security.
In general, any roof should have the following layers:
- Ventilation – intake and exhaust vents are strategically placed in the ceiling or attic to provide ventilation.
- Roof Deck – the layer that goes over the framework and serves as the foundation for everything else.
- Underlayment – a protective coating that is applied to the roof deck.
- Ice and Water Shield – a waterproof membrane with a polymer-modified bitumen adhesive.
- Ridge Vents – a type of roof vent that is a part of the roof ventilation system.
- Roofing material – shingle, shake, tile, metal, wood, or slate.
- Flashing is a flat, thin waterproof material at the intersections of several planes of the roof.
Overlooking the Roof Deck
The basis for your roof replacement is decking. If it’s weak, it won’t matter how well it’s installed because your entire roof might be jeopardized. Roofing contractors may ignore existing decking flaws in favor of pushing on with the foundation rather than constructing a new one.
You may save money in the short term, but you’ll wind up with a subpar roof replacement in the long run. Ensure that any roof repair professionals thoroughly check the decking to see whether it, too, needs replacement.
