The typical scope of installation:


Asphalt Roof System

Cover entire house with tarps for protection

Re-roofing is a very messy project, especially when removing multiple layers of shingles. We take all the necessary precautions in protecting your property with the use of heavy duty tarps draped along the entire length of your house from top to bottom. Due to uncontrollable dust, it is recommended that customers cover or remove any valuables located in attic areas.


Strip all roof areas down to bare roof boards and remove all nails

Going over an existing roof is not recommended. This process does not give you the ability to properly inspect roof decks or flashings for damage. We will replace any damaged sheathing or flashing we come across during our deck inspection.


Chimney Work

Our chimneys are known to be the best in the business! We thoroughly clean the chimney of any old tar and caulk and remove existing flashings. We then grind out all necessary mortar joints before installing brand new lead flashing. All joints and visible cracks are sealed with mortar. We do not use caulk to attach flashings to brick. Please note, TAR IS NOT ACCEPTABLE FLASHING! Any roofer who uses tar to tie into penetrations is inexperienced and will undoubtedly install a roof system that will fail. We also can remove your chimney if you are not longer in need of it.


Ice and Water Shield leak barrier

Ice and Water Shield or Bituthene is a membrane that works primarily as a leak and ice dam barrier. It is the first component installed on your new roof system. This product will help protect your roof deck in case of water damming in your gutters, wind driven rain, and, damaging ice dams. We
install this product covering at least the first 6’ of the leading edge of the roof deck. We also wrap all roof penetrations, including, but not limited to: chimneys, stove pipes, plumbing pipes and skylights.


Premium Breathable Roof Deck Underlayment

Underlayment is one of the most important elements when installing a roof system. Traditionally known felt paper has been proven to rot or become brittle before shingles can reach there useful life. This product is outdated and not recommended. To provide a critical extra layer of protection
between your shingles and your roof deck we install premium breathable synthetic underlayments. These products work as a second form of protection by preventing wind-driven rain from infiltrating under your shingles and causing damage to your roof structure or to the inside of your home. In addition, a premium roof deck underlayment will allow moisture from inside your attic to escape.


Plumbing Flashing

We install brand new plumbing flashing on every roof we do. We use an aluminum flashing boot with a rubber collar.


Aluminum Drip Edge

We use only top of the line 8 inch aluminum drip edge around the entire perimeter of all roofs. Drip edge prevents water from running down behind the trim of your home. Watch out for companies who try and cut cost with a less performing 5 inch drip edge. Customers can choose between a milled finish, white, brown or black.


Starter Strips

Pre-cut starter strips are one of the most overlooked parts of a roofing system. Most roofers try and reduce cost by fabricating starter strips out of shingle scraps. This method does not guarantee a glue line at the leading edges of your roof. We use only precut starter strips that are installed around the entire perimeter of your roof (eaves and rakes). This installation increases your wind coverage on both the System Plus and Golden Pledge Warranties.


Asphalt Shingles

Almost every steep slope residential roof system installed in the northeast involves asphalt shingles. Even with an array of premium shingle styles available, nowadays, most homeowners opt for the best bang for their buck and choose a standard 30yr architectural shingle. Despite the fact that we highly recommend and primarily install Owens Corning and GAF roofing products, we do offer installations with warranties using any asphalt shingle available on the market.


Storm Nailing or Hurricane Nailing

Manufacturers and most building codes only require 4 nails per shingle. To maximize wind warranties and overall protection we attach every shingle with no less than 6 nails.


Attic Exhaust Ventilation

Proper ventilation is required to protect your roof from premature deterioration. Heat and moisture builds up in attic areas causing mold, mildew, rot and even exterior ice dams to say the least. Properly installed ridge vents or roof vents allow heat and condensation to escape at the most
effective location – the ridge. Ventilation is code and is mandatory on every roof system we install.


Hip and Ridge Cap

Capping a roof, when shingling, is the final step in the roofing process. The cap serves to seal the ridge or hips of the roof where the shingles come together from either side. We install only factory cut cap accessories made specifically for the architectural shingles we are installing. Most companies will attempt to reduce costs by fabricating cap on site out of cheaper grade three-tab shingles. This method is not recommended when installing an architectural roof system. Not only is there a risk of color variation, three-tab shingles carry less of warranty than architectural shingles and will expire much sooner than the rest of your roof.


Clean up and Disposal

We pride ourselves with a clean worksite. All debris is hauled to the recycling facility using our own dump equipment. We do not burden our customers with third party dumpster companies. We use high powered earth magnets to assure all nails are removed from the yard – the premises will be
left in broom clean condition.
