Replace or Repair the Roof Over Your Head?


BUSTAMANTE ENGINEERS STAFF • January 30, 2023

Potential Signs That Your Roof May Need Some Attention 

The roof over your head is one of the most important parts of your house. When installed and maintained properly, it provides shelter from the elements, protection from water damage to the building, and safety and security to you and your family. Despite the importance of these functions, roofs aren’t always prioritized when it comes to maintenance, repair, or replacement…out of sight out of mind.

Does It Make More Sense to Replace the Roof or Repair It?

Over time, your roof will start to show indications of wear and tear. While there are a few things that can indicate your roof is no longer in its best shape, any one sign on its own doesn’t necessarily mean your roof needs replacing. Proper upkeep of your roof helps ensure that it stays in good condition to maximize future resale value and keeps you and your belongings protected from weather in the meantime. 

The Most Common Signs That Your Roof Needs Attention

Don’t ignore these warning signs that it’s time to inspect your roof! If you are worried about any visible symptoms of damage, the building envelope specialist from BUSTAMANTE ENGINEERS can help you decide whether a total replacement is necessary.

  • The Roof Has Outlived its Typical Useful Life - How old is your existing roof? Depending on the roofing material, the lifespan of a roof could be between 15-30+ years! Check past home improvement records to find out exactly when your roof was installed. The roof duration also depends on whether the old roof was removed and if it is properly ventilated. 


  • Water Damage in the Upstairs or Attic - Moisture marks, brown, yellow, or grey stains, and peeling paint on walls and/or ceilings may indicate a damaged, leaking roof. 


  • Roof Is Sagging - A droopy, sagging roof indicates that trapped moisture has deteriorated roof materials and may require repair or replacement. 


  • Flourishing Moss, Mold, or Fungi – These annoying additions indicate trapped moisture, which can stain a roof. To do away with organic growth that collects in shaded corners of your roof, carefully remove the matter. 


  • Buckling Shingles - When shingles start to curl, it’s a sign that they’re no longer properly adhered. The curved surface can be caught by strong wind, leading to further damage during the next storm. 


  • Missing Shingles or Significant Granular Loss – An inspection should be performed when missing and/or damaged shingles are found. Excessive granular loss which can be found in the gutters is a key indicator that your roof needs attention. 



  • Additional Consideration: Are You Planning to Sell the House? A new roof can be costly, but it will add value to your home. You may be more likely to get full asking price, spend less time with your home on the market or have shorter negotiations.

Types of Roof Products & Their Lifespan

How often a roof will need to be replaced depends on several factors, such as the quality of the roof’s installation, quality of the materials used, and the type of roof product. These are a few examples of typical useful lives of roofing types: 

  • Architectural Asphalt Shingles (laminates):  20+ years
  • Low Slope Roofs:  15+ years
  • Metal Roofs:  30+ years
  • Wood Shingles:  20+ years (depending on exposure)

Culvert Replacement Project Made Possible with Assistance from PENNVEST
By BUSTAMANTE ENGINEERS Staff August 20, 2024
The BUSTAMANTE ENGINEERS Inc. project that we are highlighting this month is CMP pipes that deteriorated and caused a portion of the pipe to collapse, and the necessary funding to complete the project. These four pipes were initially installed to allow for an existing creek to continue flowing underneath a roadway. The project was pertinent as one of the four had already collapsed and the remainder of the pipes were in a similar disrepair. The cost of replacing the 400 linear feet of pipe was a significant undertaking but made possible with the assistance in the form of a loan received from Pennsylvania Infrastructure Investment Authority (PENNVEST).
