When searching for a roofing company, most homeowners consider how long it has been operating in this business, references it can provide, whether it offers warranties on its quality, and if it carries proper insurance coverage. A roofing project is quite complex. Even small problems can cause lots of trouble. You should also ask the following ten questions when hiring a roofer.
1. Does the Job Involve Removing the Old Shingles?
Many roofers cut corners by avoiding the removal of old shingles. They simply place the new shingles over the existing ones. If the old shingles are not removed, it can lead to poor quality roofing structure. The old shingles may have developed cracks and gaps. If new shingles are laid over these damaged shingles, your roofing will develop problems quickly within a few months. An experienced roofer will always remove the old shingles before placing the new ones in their place.
2. Will the Roofer Install Metal or Drip Edge?
These aluminum pieces are placed under the shingles at the roofing edges. Its purpose is to direct the water runoff into the eavestroughs and protect the soffits, fascia, and decking. If the roofer does not install this metal part, the water runoff from the roof cannot be controlled properly, and your roof will be at risk of getting damaged easily. Unscrupulous roofers leave the installation of this item unless the homeowner specifically asks for it. Make sure you ask for it and get it installed to protect your roofing investment.
3. How Many Nails will the Roofer Use for Every Shingle?
The standard is to use at least four nails for every shingle. However, six nails are needed for each shingle if it is used for houses with a steep slope roof or a roof that falls in an area that sees the high-speed wind. The use of the correct number of nails based on the type of shingle ensures every shingle is held firmly in its place.
At the same time, the nail installation method also counts a lot.
The Nail Line: Each type of shingle has a nail line ranging from 1.5-2.5 cm. This is the marking where the nails are placed. If the nail is placed too high, it will not keep the shingle in place properly. It compromises the strength and integrity of the roof. If the nail is placed too low, its head will rust and corrode over time, leaving gaps due to natural expansion and contraction of the roofing material caused by the changing outdoor temperature. Improper nailing voids warranties. Your roof will be susceptible to storm and wind damage.
Improper Nailing: A nail driven too hard into a shingle can tear it apart and damage it. If it is not put tightly, the shingle placed above it does not touch the lower shingle closely and it leaves a gap between the two shingles. It leads to air pockets that weaken the roofing structure. An angled nail leaves a gap where water can sneak in.
4. Will the Roofer Reuse or Install New Flashings?
Removal of flashings is a complex job that requires first measuring the existing flashings, and then bending the new ones accordingly. Some roofers try to avoid the hard work when it comes to replacing the flashings. It helps them reduce the time they spend on the roofing project. However, it can be a big problem for the homeowner. The old flashings of your roof have a particular dimension based on the types of roofing structure and house design. These flashings develop problems over time, and it is best to replace them at the time of replacing the shingles. Not replacing them now can mean higher repair bills within a few years.
5. Weaving the Shingles or Using Steel underneath the Shingles
It can be a big problem if a roofer prefers weaving the shingles without installing the required metal part underneath them. Woven valleys prove cheaper and do not require much installation effort. However, it is not ideal for the homeowner. Woven valley design is vulnerable to early wear and tear. Metal valleys last longer and look better.
6. How Far the Overhang Will Extend?
Shingles require between 6 mm to 2 cm of overhang depending on various factors. It should not extend beyond 2.5 cm. Too little overhang and it will cause the water to seep into the fascia board. Your shingles become vulnerable to being blown off in the high winds. It will suck water through the eavestrough.
7. How the Roofer Will Cut the Shingles?
A trained and competent roofer uses a straight blade to cut the shingles properly. If a roofer prefers cutting it without properly measuring it or using the right blade, the shingles will be ruined.
8. Protecting the Eavestroughs
Inexperienced roofers often damage the eavestroughs if they do not use proper tools, equipment, and gears while working on the roof. Resourceful and professional roofers use ladder stabilizers and other supporting systems to work properly and safely. It prevents any damage to your roof. Ask a roofer about these risks and what supporting and safety gear they will be using while working on your roof.
9. The Cost of Plywood to Replace Soft or Rotten Decking
A Kelowna roofer could come up with unexpected bills for the decking plywood if it was not discussed earlier. You should clearly ask a roofer how much you will be charged for each plywood sheet if any decking plywood sheet requires replacement.
10. In What Condition the Roofing Crew Will Leave the Job Site?
This roofing project will take several days. The staff of the roofer may leave your home and job site unprotected during the initial days. It is necessary for the roofing company’s staff to place the tarp over the roof before leaving. They should check the garden and lawn for hazardous items like nails and clean the stripped shingles before leaving the project site.
