Installation of new shingles over existing wood shakes or worn asphalt shingles can create a warped, waving appearance. Paul Hamilton Roofing & Construction does not install shingles over existing material. We always tear off existing shingle layers down to the roof deck, ensuring a clean, properly prepared surface. Not only does this create a nice, clean, and uniform appearance, but it also helps protect your home from water infiltration, algae build up, and other issues that may develop under the new shingle layer. Moreover, by removing all existing shingle layers we are able to assess the condition of existing decking. Any soft or rotten decking is replaced before installing underlayments, flashings, and shingles, ensuring that your roof will protect your home for decades.
Ice and water shield is a self-adhering, bitumen sheet that is applied to the roof decking to help prevent ice damns - which can cause water infiltration - from forming. Current building code requires ice and water shield to be installed along eves to at least 24 inches inside the exterior wall. Paul Hamilton Roofing & Construction installs premium, IKO Storm Shield® Ice/Water Shield in compliance with current building code. In addition to the building code requirements, we also install ice and water shield along valleys, chimneys, skylights, and other penetrating structures that may be at risk for water infiltration. When choosing a contractor to install your next roof, be sure to choose a contractor that not only installs ice and water shield, but also that a premium ice and water shield product is utilized.
Current building code requires a layer of underlayment to be installed between the roof deck and shingle layers. Traditional construction methods typically used roofing felt - a mat of fibers pressed together to form a sheet and impregnated with asphalt. While many contractors still choose to install roofing felt (probably because it is cheaper), Paul Hamilton Roofing & Construction uses GAF TigerPaw® synthetic underlayment. Synthetic underlayment provides better protection against water infiltration and creates a smoother surface to enhance the appearance of the shingle layer after installation. Protect your home by demanding that your contractor use a premium, synthetic underlayment like GAF TigerPaw®.
Current building code requires flashing to be installed at wall and roof intersections, at gutters, wherever there is a change in roof slope or direction, and at all roof openings. Paul Hamilton Roofing & Construction installs corrosion-resistant flashing metals in compliance with all building codes and we always replace valley metal, drip edge, gutter apron, and other flashings with new material. Variables can affect the size requirements and placement of flashing material. When you choose Paul Hamilton Roofing & Construction to install your next roof you can rest easy knowing that we are aware of and comply with all current building codes - ensuring that your home will be protected for decades.
Hot air can accumulate and get trapped in attic spaces, which can cause moisture problems. Proper roof ventilation helps remove hot air from your attic. Paul Hamilton Roofing & Construction always replaces standard roofing vents and caps with new material. We will also advise placement of new vents if needed, and we replace all roof penetration boot flashings. We typically install adjustable neoprene boot flashings against PVC piping. However, lead boot flashing is always used against metal piping - the kind that are common among older plumbing exhaust pipes - because neoprene will deteriorate over time if installed against metal pipes.
