How Do I Know If I Need A New Roof

 How do you know if you need a new roof.  Here are some of the ways:

1.  Water damage

2.  Visible staining of asphalt single roofs

3.  Age

4.  Delamination of any building component

5.  Curled or raised shingles or roofing plies

 

Water Damage

Interior water damage is often a problem with the roof.  If you see evidence of a problem, there is often a much larger problem hidden from view.  Mold can accumulate and finishes can be ruined if left unchecked.  Give us a call to evaluate any problem, free of charge.

 

Visible Staining of Asphalt Shingles

Staining of asphalt shingles is not always an indication of a defective roof.  Sometimes, it can be killed with bleach or detergents and removed.  More often than you think, a larger problem may underlie the staining.  This is because:

1.  Roof staining is caused by algae deposits on the roof.

2.  Algae takes time to deposit and usually happens on older roofs or roofs under conditions that accelerate weathering.

3.  Algae multiplies and weathers your shingles, causing them to wear prematurely, crack, and curl.

Give us call to evaluate the extent of algae growth and recommend repair procedures.  Hopefully, only a cleaning is necessary.  It's always a good idea to address algae before it becomes a bigger problem.

 

Age

Roof materials have become significantly more robust in the past decade.  Typical warranties on new shingle roofs are 15-20 years on 3 tab shingles, lifetime for architectural shingles with a 15 year algae warranty, and 10 years or greater on flat roofs (modified bitmunous, TPO, and EPDM) depending on thickness or number of plies.  This wasn't always the case.  You can expect the following lifespan for previously installed roofs older than 5-10 years before roofing materials became more resilient to aging:

1.  3 Tab Shingles - about 10 years

2.  Architectural and Designer Shingles - about 15 years

3.  Mod Bit, TPO, EPDM, and Built-up Roofs - 5 - 10 years

If your roof is older than this, give a call to evaluate.

 

Delamination of Any Roofing Component

Delamination, or separation of a roof component away from its adjoining component, is almost always a problem.  Gutters separated from fascia do not drain.  Fascia, soffits, or trim with splits or gaps allow squirrels and birds into your attic, add heating and cooling load to your building, and allow water infiltration.  Peeling flashing or roof tiles are an invitation for water migration.  Even if it seems water should still sheet properly over a delaminated component, wind can drive rain under your roof even against gravity!  Don't allow delamination to become a bigger problem.

 

Curled, Split, or Cracked Shingles or Roofing Plies

Asphalt shingles that are past their useful life swell at the edges, fray, crack, and split.  If this is visible, especially from the ground, more extensive damage probably exists if inspected at arms length.  All mean the roof needs repaired or replaced.

Flat roof systems (mod bit, TPO, EPDM, and built-up) are sheets of roof adhered or fastened to the roof and each other.  If the plies are cracked, separated, or gaps exist between the plies, water will find its way through these defects.  Flat roofs may have some ponding (sitting water that evaporates over time), further compounding the problem.  This must be addressed immediately, especially on flat roofs with ponding!

 

Hopefully, this helps diagnose some common roofing problems and helps you judge your roof's condition.  Please reach out if we can help in any way with your concerns.
