Shingles and metal are only the first line of defense. Dee's Roofing builds in the waterproofing layers underneath that keep water out when wind-driven rain gets past the surface.
When heavy thunderstorms push rain sideways across the ridges, or water backs up in a valley during a downpour, the roofing you see isn't always enough on its own. What keeps your home dry is the waterproofing system underneath — the underlayment, ice and water barrier, flashing and seals that catch water before it reaches the decking.
Dee's installs synthetic underlayment across the roof deck and self-sealing ice and water barrier in the most vulnerable areas: valleys, eaves, around chimneys and skylights, along walls, and at low-slope transitions. Those membranes seal around roofing nails and give water a second barrier to run off of instead of soaking in.
We also waterproof problem areas on existing roofs, from resealing flashing to adding protective membranes on low-slope sections. Dee's is family-owned, licensed and insured, and your estimate is always free.
These are the areas where extra protection makes the biggest difference.
Where two roof planes meet and channel heavy volumes of water during storms.
Protected against water backing up under the first rows of shingles.
Barrier and flashing combined around penetrations that interrupt the roof.
Shallow areas where water moves slowly and needs a continuous membrane.
Shingles shed water in normal rain, but wind can lift tabs, and debris or backed-up gutters can push water uphill under them. Without good underlayment and barrier beneath, that water goes straight to the decking.
Valleys, chimneys and wall intersections are where most roof leaks begin, because water is concentrated or the roof surface is interrupted. Extra waterproofing in those spots is inexpensive insurance during a new roof installation.
Darrell makes sure these layers are installed properly on every roof we build, so your home stays dry through every season East Tennessee throws at it.
Here's how Dee's waterproofs a roof from the deck up.
Underlayment is a water-resistant layer installed over the roof deck and under the shingles or metal. It acts as a backup barrier if water gets past the surface.
It's a self-adhering membrane that seals around roofing nails. We install it in valleys, eaves and around penetrations, where leaks are most likely.
In many cases we can reseal flashing, add protective membranes on low-slope areas, and correct problem spots without replacing the whole roof.
Wind-driven rain and heavy water flow can push water under shingles in valleys or around flashing. Better waterproofing in those areas often solves it.
Yes. Underlayment, barrier in vulnerable areas and proper flashing are part of every new roof Dee's installs.
