Roof Components – A Matching System
Roofs can comprise of many intricate components, including water/ice protectors, shingles (hip/ridge), strips (starter), flashing, shingles, and vents. Ideally, these are made to act in accordance with one another. It is generally recommended that your roof components and materials come from the same company.
Nails per Shingle
Each manufacturer has different instructions on the number of nails that can be used per shingle. No two shingle designs are inherently the same. If this question is pertinent, don’t hesitate to ask it.
The Recommended Form of Flashing
When a roof meets a structure such as the chimney or dormer, these areas tend to be very vulnerable to moisture and water infiltration. Flashing is going to be the main defense from moisture getting in through these areas. There are many types of flashing in the marketplace so be sure to ask what kind your roofing contractor is using and what they suggest depending on what the home’s siding is made of.
Sealing off a Pipe Boot
Pipe Boots are used where the vent stacks penetrate the roof. This is of concern for some residential homeowners because a lot of pipe boot companies do not provide a warranty. Therefore, a pipe boot must be sealed off correctly. Failing to do so may lead to quite a lot of damage.
The Type of Valley Installation Used
Roof valleys can also be vulnerable to leaks. It is in this area that water can accumulate after a rainfall. Because of poor installation, many homes experience significant leaks in these areas. A thorough valley installation should include some combo of water or ice protectors, flashing, and/or shingles installed in accordance with manufacturer’s instruction. Ask your contractor what tactics will be employed and how exactly everything will work.
Capping off Ridge Vents
Ridges have vents that allow the roof to be breathe in a sense and stop water from accumulating. This portion of the roof is unfortunately the area that experiences the most wind shear. Find out what a contractor intends to do to cap off and protect these ridge vents from future damage.
How Far Shingles Will Extend Past a Drip Edge
Ideally, when there’s a rainfall, water trickles down the slope and into the gutter. The reality is not so simple however as some rain tends to stay on the edge of a shingle. Although a drip edge is installed, water can make its way underneath the shingle and reach the roof deck, causing damage. Find out if the contractor intends to lengthen the shingle edge over the drip edge.
