Roofs by Nicholas has spent years refining and improving our processes to insure the roof repair or replacement at your home will go smoothly, quickly and the results will meet all your expectations.
Prior to any roof installation, your estimator will have provided you with the specifications and applications to do your job right. As part of the reroof process, we may need to obtain a permit from your local jurisdiction, and we obtain all permits and handle all related fees, inspections and final job sign offs.
Removal of your existing roofing is the first task performed by our crews. The process can take about 4-6 hours depending on the size and steepness of your roof. Some existing roofs have multiple layers of roofing that can increase the time and cost, and we always remove all layers down to the original roof sheathing. This allows us to thoroughly inspect your existing sheathing and rafters for dryrot, termite or other possible water damage that may have occurred over time.
The Roofs by Nicholas process includes cleaning as we go to and our teams will leave your site completely clean, including the gutters. This is the “dirtiest” part of the roofing process and our professional procedures include protecting your gardens, bushes, pool and air conditioning system.
Upon removal of all existing roofing, we will inspect the existing roof deck for any structural damage of the roof deck caused by possible dryrot, termites or water damage. Many city and county inspectors will also conduct tear off inspections as part of the permit process. We are required to replace all damaged wood members. In the unlikely event that your house has structural damage , we will advise you, allow you to inspect the areas and provide you a detailed quote to bring your house back to safe standards.
Most existing homes in the Texas Area originally roofed with wood shakes or shingles were built with spaced sheathing. This is identified by boards running horizontal to the rafters with a 4”-6” space between them. Spaced sheathing can still provide an adequate roof deck for the installation of wood shakes and shingles, or can be used as a substrate for new solid sheathing such as OSB or plywood.
Homes originally roofed with asphalt shingles, or built after 1990, were constructed with solid sheathing, using 1” nominal sheathing or plywood. Most existing solid sheathed roof decks provide an acceptable substrate for any new roof material.
Installation of new solid sheathing on homes with existing spaced sheathing is very common in reroofing. The use of Oriented Strand Board (engineered wood or OSB) is widely used in reroofing, along with CDX plywood.
This installation of new solid sheathing can take up to 8 hours, is always installed on top of the existing spaced sheathing, and is commonly inspected as part of the permit process.
All roofing materials require an underlayment of asphalt saturated felt (tar paper) or an equivalent approved material to assist in achieving a watertight roof system.
Underlayments are no longer rated by pounds (15lb. or 30 LB) but by Type as determined by ASTM ratings. Fiberglass reinforced felt membranes are made and recommended by most shingle manufacturers, and are the only felt products warranted with the roofing product. Some low slope applications will require self adhered membranes also made and warranted by the shingle manufacturer.
Every roof requires flashings at all valleys, walls and penetrations (pipes, vents, chimneys and skylights) to perform effectively. Roof by Nicholas, your Texas roofing experts, replaces flashing wherever necessary. Flashing and other roof penetration points are the number one cause of roof leaks. Roofs by Nicholas takes the unique extra step of sealing the valley and access points with Ice & Water Shield to prevent potential leaks from heavy rains or the slow melting of ice and snow during the winter.
New building codes, product warranties, and the installation of solid sheathing all require additional attic ventilation as part of the reroof process. Ventilation is a key component to maximum roof performance, and plays a vital role in a home’s comfort during hot summer days and cold winter nights. Additional venting at the eaves, combined with eyebrow vents or continuous ridgeventing, will be specified to meet the new demands of your roof system.
Composition shingles are the most common product used for reroof. Invented by Owens Corning in 1978, They are lightweight, walkable, fireproof, and affordable. Asphalt shingles come in a variety of styles and colors and offer extensive long term warranties. Always installed over solid sheathing, they require ASTM underlayment, zinc coated nails, proper ventilation and all shingles have specific install specifications and patterns. Roofs by Nicholas teams are trained in the proper installation of each shingle to ensure you are protected by the full Manufacturer’s Warranty.
Both Concrete and Clay tiles are available in standard weight (new construction) and lightweight (reroof) and are always installed over solid sheathing. Roofs by Nicholas recommends and installs a double underlayment of ASTM felt, and lead based two piece flashings. A structural inspection is available if deemed necessary, and the walkability of the roof should always be considered prior to choosing a tile roof.
All shake roofs are available in Class “A”, “B”, or “C” fire ratings and are legal in all city and county jurisdictions. Shake roofs require a Type 30 ASTM felt underlayment, two galvanized fasteners per piece, and function best when installed over spaced sheathing. Different qualities of wood grain and product thickness can greatly affect the price even though the installation specifications are the same.
All jurisdictions require a final inspection and sign off from the local building department. All work is to be completed prior to final, and the jobsite left clean and free of roofing related debris. A properly completed roof project and complete customer satisfaction are essential to our success and a true indication of our performance.
