Warrantied Roofing System
The keyword here is “System.” Each manufacturer has its unique type of roofing system consisting of (x) amount of components that are required to get their full warranty (different manufacturers have different requirements). This is the most comprehensive protection you can get for your roof, according to the manufacturer you, or your roofing contractor, decides to use. Usually, these consist of:
- Ice and Water Shield
- Synthetic Underlayment
- True Starter Shingles
- Architectural Shingles
- True Hip and Ridge Shingles
Standard Roof Replacement
A true starter shingle has a critical fast-acting adhesive strip that helps bind the shingle to the eave and rake of your roof to help prevent wind damage. These starter shingles are a key element in wind defense for your roof. To cheat this system, roofers will take a 3-tab shingle, flip it around, and use that. This does not offer the same protection. Without the adhesive strip, the eaves of your roof are vulnerable to excessive wind because they have nothing bonding the edge of the shingle to the eave.
hip and ridge shingles
True hip and ridge shingles are meant to flex. A normal shingle IS NOT. So when a roofer takes a 3-tab shingle, cuts it into three sections, and bends those over your hips and ridges, the shingle loses many of its granules along that crease, which exposes the underlying fiberglass base. Now it is only a matter of time before the Sun wears down that shingle, cracking it, creating a breach in your roof.
- You are not tearing off the existing roof and seeing what is underneath. After a roof has been stripped, it gives a lot of insight into the actual condition of your roof decking.
- It adds unnecessary weight to your roof. While this may not be a catastrophic issue for an uncompromised structure, it could easily lead to disaster if it sits atop a failing one.
- If you are only re-roofing a section, then it will be painfully apparent since the shingles will most often not match. New shingles won’t match old ones even if they are exact matches, because the old shingles suffer from sun bleaching and other elements that wear on the coloration.
- It makes it even more difficult to track leaks. If the shingle-over begins to leak, then that water could travel many directions down the old shingles until it finds a way to leak inside your home. This also traps more moisture between those layers atop your roof.
