Tips & Tricks

homeowner adding shingles

Learn a few secrets contractors have learned through years of installing roofing.

We have listed some tricks of the trade that might help you. Be careful when accessing a roof and always use fall protection!

Roof cleaning

Water and a rake can do too much damage to your roof, but a leaf blower works well and is safe for your roof. Blowing from the ridge downward will remove a lot of debris from your roof. This also works great for the end of a new roof job.

Roof sheathing

When tacking your roof sheeting in place, use a chalk line to mark where your rafters are. This will help later and makes it easier for nailing the sheathing.

Roof ventilation

Use the 1 in 150 rule which most manufacturers require. Take your square footage of the living space and divide that number by 150. That will give you the total square footage of ventilation you need for intake and exhaust. For example, a 1,500-square-foot living space divided by 150 is 10 feet. 50% of that should be intake and 50% should be exhaust.

Roof access

Ladder safety is important. This is where a lot of accidents happen because you go up and down a ladder many times in one day when working on a roof. When using a ladder, make sure to:

  • Tie off your ladder to the roof so it will not slide.
  • Have the ladder extend three feet above the roof edge.
  • Always have your both hands on the ladder. Use a rope tied off to your tools and lift them up when you are on the top of the roof.

Roof systems

Most roofing systems have the instructions online. Be sure to review them and ask a question if you need to. The more knowledge you can gain the better off you will be. Learn the roofers language with these terms.

Nailing

Please review the installation sheet of the product you are using. It is easy to do online. Placement of the nails is important to have a warranty in place and more importantly having a good roof. Most asphalt roofs require four nails. In some high wind areas or with steep mansard type roofs, six nails are required.

Clogged downspouts

Many people will try clearing a clogged downspout by putting a garden hose down the downspout, while others try using a leaf blower. Both may be successful, but if not, try using a leaf blower and inserting the nozzle into the bottom outlet of the downspout and blowing upwards to loosen the clog.
