Most contractors don't inspect the wood decking. We, however, take the extra step to inspect the entire roof decking for overall strength and ability to securely hold the nails and shingles.
Without proper installation of underlayment your decking will be exposed to moisture that will cause your decking to become soft and appear wavy. This can also cause the shingles to crack and deteriorate more quickly. We use plastic caps or tin caps with staples to install underlayment. Also, if requested, we can use Valley Fast or Ice & Water Shield in the valleys giving protection like no other valley product. Although you don't see this from the street, it is a very important protection.
We have addressed all areas of shingle installation to help ensure the very longest life of your roof. You can have complete confidence that our certified crews will exceed the manufacturer's guidelines. For instance, if requested, we can nail each shingle with six nails, rather than the industry practice of just four. We also use starter strip rather than the industry practice of just using strip shingles. This ensures your starter seals at both the top and bottom. To protect even further, we add shingle sealant around the eaves for the maximum wind protection possible.
Flashing is a metal sheet that protects against leaks, however if not done correctly can be the place where most leaks occur. Many contractors give a minimum amount of attention to these areas. We recognize this to be the most important places to prevent water leaks. We apply a superior flashing sealant (NP1, a super-rubber) which is nothing like silicone which cracks and leaks over time. We paint vent pipes, gas vents, exhaust pipes and all other roof accessories to prevent rust and match the color of the roof you choose. We also seal the exposed nails with NP1 and use lead stacks instead of the commonly used rubber. Lead stacks usually last about 95 years longer than rubber. With all these steps, you will have a leak-free and beautiful roof.
