Tell Me About My Roof!

Roof Covering

This is what you see when you look at your roof.  These are the shingles, wood shakes, tile or metal.  Underneath this is the underlay material  that protects the sheathing from the weather.

JLC Construction in Jacksonville is a Fl Licensed Roofing Contractor and a Fl Licensed General Contractor.  We can provide advice on roof repair or replacement and/or give you a professional inspection of your roof to determine needs.


These are the boards or sheet material that are fastened to the roof raters to cover a house.  The roofing and underlay materials are attached to the sheathing.

Roof Structure

The rafters and trusses constructed to support the roof's sheathing are called the Roof Structure.

Flashing and Drainage

The flashing is the sheet metal or other material installed into a roof's joints and valleys to prevent water seepage. The drainage is a roof system's design feature, shape, slope and layout, that affects its ability to shed water.

How Long Does It Take to Replace a Roof?

Re-roof or new construction depends on the the type of roof, the weather & the inspections needed. generally for 1,500 sq. ft. home it can take a few days.  JLC works to get your roof repaired quickly!

What about Asphalt Shingles?

Asphalt shingles are the least expensive per 100 square feet.  They are the number one residential roofing material in the USA because of their durability, variety of styles, different types and different designs. JLC can discuss your options and best pricing.

What is Thermoplastic Polyolefin, TPO?  Why is TPO Used for Florida Commercial Roofs?

TPO single ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance & installation advantages. As demand increases for heat-reflective and energy efficient roofing systems, TPO single ply roofing membranes continue to provide exceptional resistance to ultra-violet, ozone & chemical exposure.

What Affects My Roof's Performance?

Florida elements such as Sun, Rain, Wind, Condensation, Moss & Algae, Trees & Leaves and Missing or torn shingles, and/or Shingle & Flashing Deterioration all affect Roof Performance.


A deteriorated roof system only gets worse with time therefore should be fixed or replaced as soon as possible to keep the damage and cost of repairs at a minimum.
