Never bid on any residential property before ascertaining that the roof is in perfect condition. The exhilaration of buying a new home can cause you to forget that critical step in the purchase process, but that can be a costly mistake.
Roofs are expensive to install and contribute significantly to the property value. Upgrading one after purchasing a house can affect your finances for several years. Ensure the roof structure is sturdy and well-maintained, with longevity that can last long after you buy the house. Otherwise, reach out to our roofing Niagara professionals to help fix any roofing problems you may have.
What to Look for When Buying a House Checklist
Life expectancy
One of the main determining factors for roof replacement is lifespan. The closer a roofing material gets to its life expectancy, the more problems will arise, forcing you to replace it eventually. Check the paperwork for an official last replacement date, then compare them with the lifespan of the roofing material. Do not rely on verbal confirmations without reading the official home improvement document.
Other signs that can show you the state of the roof are:
- Deficiencies like worn-out shingles or bald spots.
- Presence of mould, especially on the panes that should neither be curly nor bulging.
- The roofing material should be lying flat on the surface.
- Cracking, curling, peeling, or shrinking roofing material.
- Rusting or cracked caulk.
- Worn out rubber seals around the vent pipes.
All of the above are signs of problems that could result in costly repairs or replacements.
Point to note: every roofing option has a different lifespan. Some can last more than 50 years, others approximately 15 years. Keep that in mind when checking the roof age.
Roofing Material Quality
Cheap, architectural, and dimensional roofing materials all have different quality levels. For instance, architectural shingles are sturdier and more resistant to damage by weather elements. They also have better durability and will not require regular replacement.
Metal roofing types like standing-seam or galvanized steel also have a longer lifespan and better value. They have a lifespan of at least 50 years when installed properly. That is why some metal roofing types are known to last a lifetime. Establish whether the roofing material has a valid warranty, then have it transferred to your name.
Ventilation
Poor ventilation can cause several issues, including mould growth and limited airflow. Good ventilation allows an inrush of sunlight and airflow that ensures the proper flow of hot and cool air remains optimal. The roof only enhances energy efficiency if the ventilation system is working correctly.
The Attic
Climbing a ladder to the rooftop is unsafe if you are not a professional. However, you should not close the purchase deal on the property without assessing the attic. Most moisture-related issues manifest in the attic before anywhere else – it is the first place you will notice mould, mildew, stains, or other problems associated with leaking roofs.
Check for:
- Discolorations: The area beneath the roof should not have stains, especially on the structural wood.
- Insulation: The attic should have an effective moisture barrier to make the space more comfortable.
- Ventilation: Inadequate ventilation restricts air circulation, which means the air will not have a passage into and out of the space. Check the functionality of all vents.
- Streaks of light: You should check for that on a sunny day. The existence of pinholes that allow beams of light into the attic shows the weak or compromised points on the roof. You can consult an expert to discuss the best solution depending on the level of damage.
You can also conduct such inspections from the loft area of a house. If you are uncomfortable reaching the attic, call a roofing specialist or find as much information as possible from the loft.
Inspect canals and seepage system
Seepage systems or canals are not the first elements that come to mind when exploring what to look for in a house when buying. They are critical during roofing assessment because they determine how well water drains away from the house foundation. The system includes gutters, downspouts, and drainage pipes. Look for broken shingle pieces or granules in the gutter eaves. The more you find, the more damaged the roof is. The shingle grains protect the roofing material from damage by sun rays.
Gutter evaluation is better done by professionals who know how to navigate the dangers and what to look for – an expert can notice signs that an untrained eye will miss.
Mould growth
Mould manifests in various colours ranging from brown to black. Some can remain hidden for extended periods, and others become noticeable as soon as they grow. They usually develop because of water intrusion.
Surfaces to check for mould include walls, floors – under carpets, or other moist, dark, and warm places. The longer you ignore the mould, the more it spreads to other surfaces. Sometimes the fungi thrive in a warm climate, contrary to what most people believe.
Eliminating the mould without fixing the source does not provide a lasting solution. Investigate the roof for potential moisture sources.
Breaks and leaks
An insignificant leak on the roof can cause too much damage to the house interior if not fixed. The damage can start on the upper levels and spread to the walls and floors. The result is frustration and repairs or replacements that set you back financially.
Other than damaging several elements in the house, including furniture, leaks can destroy finishes like paintwork. The longer it remains unresolved, the more the house structure becomes compromised. You end up with a mess that is overwhelming to handle. The frustration can worsen if you realize the problem soon after purchasing a property.
Being impossible to trace only worsens the situation because water tends to travel farther away. You can check for the leak source in valleys, chimneys, or vents. Time the inspection after rainfall when traces of water are easy to follow.
Hiring a professional may save you the trouble of finding the leak yourself. You get all the facts and go the extra mile to discover other issues with the roof. You can save a lot of money by involving an expert roofer.
Additional tips
Work closely with the inspector investigating the roof and ask them to write a final report after completing their assessment. A written document can come in handy when negotiating the property price. Ensure you work with a dedicated inspector and follow their recommendations. Remember, professionals know more about what to check in a roof when buying a house and are less likely to disappoint you.
