Roofing Issues & Home Inspections

Roofing Issues & Home Inspections can Identify Required Shingle Replacement

Roofs are expensive to repair and replace and know the condition of your new homes roof is why you require a professional home inspection.  We inspect asphalt composition shingles, metal roofs, wood roofs and flat roofs whether tar gravel, composite or membrane.

Asphalt shingles have a life expectancy of between 15 and 25 years. With age, asphalt roof shingles will begin to cup either up or down. They will blister and have granular loss.

The Barrie Home Inspector will inspect your entire roof and includes pictures of shingles, flashings and deficiencies in a computerized report.

One of the common entry points for water is through the roofs flashing.  Flashing is typically sheet metal designed to prevent water from penetrating behind the roofs protective covering.  Flashing is usually nailed and caulked to exterior walls and sometime protected by a cover flashing.  When getting quotes for a replacement roof always remember to ask if the price includes new flashing.  Older flashing is unsightly when rusted and riddled with nail holes from multiple roof installations.

All modern shingles manufactured in North America have mats made of interwoven fiberglass strands, so you may also hear them called “fiberglass” shingles.  A modern shingle consists of a fiberglass mat embedded in asphalt, and covered with granules on the surface that faces the weather. The mat, asphalt and granules act together to form a durable, flexible and waterproof assembly.

As part of the roof inspection we look for the following:

Cracked caulking on flashing –  This can allow water to enter behind flashing and damage wall components and sheathing.  If left unchecked water can enter home doing damage to insulation damaged-flashing-120x90 Roofing Issues & Home Inspectionsand drywall and even creating a possible mould problem.

Shingles Curling or Blistering –  This is a warning sign that your roof shingles are going to require replacement.  Typically the protective granular coating wears off the shingle which allows the sun and UV rays to start deteriorating your shingles.

Missing or Broken Shingles –  Wind, hail or walking on roof can potentially damage or tear a shingle.  If not repaired this is an entry point for water which can lead to expensive water damage.

Flashings for plumbing, heat and exhaust ducts – Cracks in rubber boots or cracked caulking at vents etc can also allow water entry.

Replacing any broken shingles is a fairly easy and inexpensive repair.   Caulking is also very inexpensive but is a very important part of preventive maintenance.  Caulking is an ongoing process in the preventive maintenance of a home.  Checking and sealing any cracks or loose flashing is also easily accomplished.

Cost of Professional Repairs

Contact listed professional roofing companies and seek at least three bids for repair work. You can use a handyman for minor fixes and possibly shave costs, but the person should be bonded, have proof of liability, and have workman’s compensation insurance.  Make sure everything discussed on re-shingling roof is included in written contract.  Important items are make and quality of shingles,  type and amount of “ice and water shield” and what new flashings are to be installed.   This could be the time you also may want to install new roof vents and plumbing flashings etc.

Part of your roof inspection also includes masonry chimney for wood stove and fireplaces.  Certified WETT Inspections for Alliston, Barrie and Orillia are available for only $50.00 when included as part of Home Inspection package.
