Warranty and FAQs

Osborne Roofing wants you to be able to sleep at night and not worry about the big weather system heading our way. That’s why we give an unbeatable workmanship warranty on all roofs we install. As long as you own the house we will warranty our work. 

In addition to this we are able to offer enhanced warranties on the shingles due to our status with the manufacturers. A standard roof warranty is 10 years on the shingles before it becomes pro-rated and then depending upon the life expectancy of the product the warranty changes as each year passes. The majority of roofs we install are warrantied for 50 years.


Some warranties are fully transferable, normally for a small fee, depending on the manufacturer.

As a preferred installer, Osborne Roofing is often able to give enhanced warranties on our installations, which are backed by the manufacturer.

FAQ Roofing Osborne

Vents are a very important part of the roofing system, they allow the attic space to release warm air during the summer and cold air during the winter so that condensation doesn’t form. When we measure the roof it indicates to us the correct number of vents required, often newer homes have the bare minimum number of vents and sometimes the wrong kind of vents for bathrooms.

Synthetic underlayment gives superior protection for your home at a reasonable cost, it’s a second layer covering the house under the shingles. The lower the pitch of the roof, the more important this protection is.

Ice and water shield is an asphalt product that has a sticky backing on it. It is applied to areas of the roof that need extra protection. The ice and water shield seals around the nails that penetrate it, this product gives superior protection, as it’s more like a rubber membrane underneath the shingles. It is typically only used at the roof edge, valleys, skylights and chimneys because of the cost.

You can install a second layer of shingles, but we don’t recommend it. It voids the warranty on your new roof and decreases the life expectancy too. Homes with 2 layers of shingles tend to need more plywood replacement due to rot when re-roofing at a later date.

There are several factors which determine the cost of a job. The pitch of the roof will make the biggest difference, it will probably cost more as it will need more material and it’s much slower for the roofers because of the danger involved in moving around on the steeper pitch.

  • Length of valleys
  • Skylights
  • Chimneys
  • Access to the roof
  • Type of roof decking (plywood or pine board)
  • Amount of property protection required

Flashings protect the intersections between brick and shingles. The metal flashing directs water that’s running down a brick wall onto the shingled slope below. The wall flashing also hides the “step flashings” so it’s also partially a cosmetic flashing. Wall flashings don’t always have to be replaced. They can often be re-used but many people choose to replace them as they tend to fade over time. They are the last component to be installed so they do not have to be replaced at the same time as the shingles.

Drip edge is used at the edge of the roof near the eaves trough. It’s designed to support the shingle and direct the water into the trough. It also helps prevent ice from pushing back underneath the shingles during the wintertime. It can also help prevent small animals from entering the attic space, especially squirrels.

We use roofing nails that are 1¼” long. Most installers use pneumatic air guns some use roofing hammers. Sometimes ice and water shield or felt paper is installed with staples as they are just being held in place until the shingles are installed.

Deck mounted skylights are attached to the roof decking (plywood or pine boards). It’s often best to replace this type of skylight at the same time as the shingles because the flashing kit needs to be installed with the shingles.
Curb mounted skylight are attached to a frame (typically made from 2×4’s) that is attached to the roof deck. If the flashing that surrounds the frame is in good condition the skylight can be replaced at a later date if required.

We install both Velux & Columbia skylights. We recommend changing skylights when the roof is replaced as it’s the perfect time and cheaper since there is a crew already on site. We also suggest changing any acrylic dome skylights to flat glass versions as they are less problematic.
