With all of the different types of roofing materials, choosing the nails or screws that will do the job and best practices for applying them takes experience.

From metal roofing to ceramic roof tiles, let’s take a look at some of your options for the best fasteners for various roofing materials, starting with asphalt shingles.

Asphalt Shingle

With asphalt shingles, the top choice for protecting them against wind uplift is roofing nails. When applying asphalt shingles, fasteners should be placed below the adhesive strip, equally spaced across the shingle, and placed in slightly from the ends.

Metal Roofing

Here are some tips for self-tapping metal fasteners:

  1. Use the right fastener. Screws and fasteners have metal-to-wood and metal-to-metal applications.
  2. Use a fastener that has a large washer.
  3. Hi-Lo threaded screws are used in metal-to-wood applications. (Tek screws are used in metal-to-metal applications. Stainless steel screws should be used when screwing down aluminum metal roofs. )

  4. Protect against corrosion and rust by using mechanically galvanized fasteners.
  5. Variety and choice matter.
  6. Instead of carbon steel screws use stainless steel or zinc aluminum cap screws.
  7. Look for and use fasteners with a strong V-neck head to prevent product breakage while on the job site.
  8. Coordinate color of roofing screw with roof panel color.
  9. If you needed the screws yesterday look for quick ship options.
  10. Use fasteners from a reliable company.

When positioning the screws, they must penetrate the underlying structure to show a minimum three laps of thread when fully seated. This will ensure that the self-tapping screw threads are securely engaged to provide maximum durability.

Ceramic Roof Tiles

Clay and slate tiles can be attached to the roof deck using a variety of fasteners such as nails, wire, concrete, and metal clips. Another popular way to secure these heavy tiles is polyfoam, as you will see in the following video:

 

Battens are usually made of wood and they are what each tile is fastened to. Laying out the batten strips properly is the key to a symmetrical tile roof.

Flat Roof System

Originally constructed with tar and felt paper, a modern flat roof generally uses a membrane made of synthetic rubbber. It is applied over a liquid coating and then held down with an adhesive.

Wood or Shake Shingles

Use stainless steel, galvanized, or aluminum two-inch nails when working with cedar. If you use stainless steel, choose your alloy based on

your distance from the ocean. Use a 316 alloy if you live less than 15 miles from saltwater; otherwise, use a 304 alloy. Using a nail with ring shanks prevents the nail from popping out as your cedar roofing expands naturally.

Nail guns tend to fire the nail too far into the shingle, causing it to crack and eventually fall off. Also, firing the nails quickly can cause you to miss the skip sheathing beneath the shingle. Any missed nails will be more likely to cause shingles to crack and curl. To avoid this, hand-nail two nails into each shingle. Place the nails four inches from the top and one inch from each side.

One critical step that is many times forgotten with shake shingles is to climatize them before installation. Place them under a tarp and off the ground so they can adjust to the temperature and humidity of your climate.

Be sure to check with your insurance provider before having a Denver Roofer install wood shingles. Along the Front Range of Colorado, especially in the foothills, there have been enough wildfires that some insurance companies are a little apprehensive about covering homes with wood shingles.
