Roof replacement is one of the most important areas of home maintenance and construction. There is a difference between a roofing contractor and a shingle installer. The latter focuses on shingle replacement, but may cut corners on the project’s structural phases. These shortcuts can result in higher utility bills and future problems with the roof. Poor-quality materials or workmanship can literally leave you ‘out in the rain’. When hiring Roofing Companies McHenry IL, ensure that they take the steps below.

Removing the Roofing Down to the Wood

Your existing roof covering (tile, slate or shingles) should be taken down until the sheeted deck or plywood is exposed. Most shingle manufacturers void the warranty on any shingles installed over existing roofing; hire a contractor that follows manufacturer recommendations on roof replacement.

Taking off the Flashing

Existing roof flashings should also be removed, and any rotten or damaged wood replaced. If not, the wood can cause structural failure.

Removing Tar Paper

Taking off the tar paper allows your roofer to inspect the roof deck before installing underlayment and shingles. Sheathing nails must be inspected, and reapplied if necessary.

Installing Underlayment

Underlayment should be installed before shingles are laid. Most Roofing Companies McHenry IL choose either titanium or tar paper; both work but titanium is more heat-reflective.

Installing Water Shields

These should always be placed at the gutter ends of any roof. Most roofers find that these end line shields have been installed improperly, and a good roofer will seal the area between the roof and the fascia board with a seal cap or a gutter apron.

Ensuring Proper Ventilation

A poorly-ventilated roof will shorten the life of your roof covering and deck. A good roofing replacement contractor will install continuous ventilation at the roof peak, and at the first rows of shingle starter areas. Many homes are without soffits which allow air to flow out. If your home’s roof prevents ventilation at the top and bottom, your roofer should install shingle vents at various locations.

Your roof is your home’s best defense against wind, rain and snow. The average roof will last up to 20 years, and regular maintenance can extend its life span. When it is time to replace your home’s roof, All States Exteriors will do a thorough job by following the steps above.
