This attention to the smallest of details ensures your project will be done correctly.

A Look Into Roofing Installations & Repairs
Every roof replacement and repair has its own specifications, as very few roofs are exactly alike. One certain thing is shingled roofs are not waterproof, as they are meant to shed water. With this in mind, all the conditions that apply to roofing will be intended for moving water off the roof. Following the IRC, the IBC and each manufacturer’s recommendations is essential in producing solid and functional applications. Knowing this, we approach roofing the following ways. All members of our team are insured for both liability and for workers compensation, and are trained in worksite safety measures to OSHA specifications.

Pre-Inspecting the Job Site
A site preparation is always performed before any project is approved. We take notes and utilize these to foresee any issues with protecting all structures, landscaping and utility installations.

Special care is taken at this time to ensure all necessary tools and procedures will be on site. Measurements are taken with careful care to obtain the best material lists possible to get the most out of each labor provider’s time, including measuring the amount of existing materials to be replaced that need to be taken away from the site once the project is complete. Calculations of the attic ventilation are done to verify a healthy breathing space is above the living sections of the home. These take into account any intake provided by gable and soffit vents; and mechanical or electric intake. Exhaust is then calculated and verified, and if it is sufficient, we will provide the same or equivalent materials. If not sufficient, we will then recommend to the homeowner proper ventilation techniques, and ensure they are installed according to local Minneapolis regulations.

Removing Existing Roofing Installations
Generally, removal is done in the mornings. It begins with the proper placement of either a Roll-Off Container or a Construction Waste Trailer selected for size and maneuverability for each site. Tarps are hung to protect the side walls and the landscaping. Plywood is used where a tarp will not provide the necessary amount of protection. Safety equipment is installed to ensure all labor penetrations, furnace exhaust, sidewalls, gutters, etc. are maintained throughout the process. Old flashing and ice and water protection is then carefully removed, and we always look for any areas that may have been previously tampered with, such as damp sheathing; loose mortar or brick; and stucco coming off walls; siding beginning to deteriorate and may need replaced, and went undetected during the pre inspections.

Ice and water has strong adhesives and needs to be scraped from the ends of the eaves, valleys and penetrations with great care to ensure the correct adhering of new applications. Any items that need to be removed to re-roof and replaced at the end are carefully set aside until completion of the reapplication. If re-sheathing the roof deck is necessary, photos are taken at all stages to ensure inspectors and homeowners alike will be sure that all work was done properly according to local regulations.

Roofing Installation Process
In most cases, roof loads are delivered, unless landscaping or other customer concerns need to be met. In rare occurrences, we will provide rooftop deliveries, as often these result in a compromised driveway, especially asphalt. At this time, we then apply:

  • Chimneys over 30″ wide to an elevation require the installation of a cricket. We install our crickets to be functional, yet eye pleasing, by building up the “V” with lumber, then using valley metal to finish.
  • Application of a drip edge to eave ends: this ensures the ice and water barrier will be placed over the drip edge preserving the watershed.

Ice and Water Application

  • Carefully placing this over the drip edge from each eave end on gables.
  • Placement of Ice and Water is then applied to each valley per local regulations. Generally we will use an entire width of a roll.
  • Apply Ice and Water to any sidewalls, chimneys prior to the installation of any flashing; to all roof penetrations present: this includes plumbing pipes, electrical masts, roof vents, exhaust vents, turbines, etc.; and application is sometimes needed for manufacturer warranties on all ridges, and when necessary, this is also applied.
  • Underlayment is then applied to the remaining roof decking. Specialty underlayment is used occasionally for manufacturer warranties, or for roofing system warranties. This is applied with 5/16″ staples or roofing felt caps, depending again upon pitch and application.
  • Drip edge is then applied on all rake edges over the Ice and Water and felt to ensure wind will not catch under the felt.
  • 24″ Galvanized or aluminum valleys are applied, ensuring a minimum of a 6″ overlap where one piece will not cover entire length. Occasionally, a homeowner will request the valleys be woven, then rolled valley is provided. Flashing to sidewalls and chimneys are then applied.
  • Starter asphalt shingles are then applied to all cave edges and rake edges.
  • Asphalt shingles are applied per manufacturer’s specifications with correct fasteners in nailing pattern and location specified for wind and warranty purposes.
  • Pipe jack plumbing and roof vents are placed as shingles approach them. They are installed on the top of lower shingles to continue the water shedding. The upper shingles are then applied by “stepping” into place to provide the proper watershed.
  • Caulk is used on any nail tops to give additional protection.

As asphalt shingles are placed by side walls, chimneys and dormers, followed by being counter flashed. Trimming of edges is then performed on all eave and gable ends.

Cleaning Up The Work Site
All work sites are then picked up and rolled over with magnets to ensure all fasteners are disposed of and all previous materials and paper, tape, etc. from new products is removed from the site. The waste container is removed, and we make sure the underside of the container is also swept and no waste is left behind.

Final Walkthrough
After each re-roof, Delta Construction walks the homeowner through a detailed checklist, and make sure they understand all we have built. We get a signature from them the job is indeed complete per the contract and their expectations. They are left with a 10-year craftsmanship warranty from Delta Construction, Inc. along with any and all manufacturers’ warranties in place. Often extended warranties from manufacturers are paid for by the homeowner, and those too are explained in detail.
